Yes, some soldered laptop memory can be upgraded—but usually not by the laptop owner. In the unusual cases where it works, a board-level technician removes the original motherboard-mounted BGA DRAM chips, installs compatible higher-density chips, changes any required board configuration, and thoroughly tests the result.
A documented Dell XPS 13 7390 modification increased memory from 8GB to 16GB. It proves that “not user-upgradeable” does not always mean “physically impossible.” It does not make soldered RAM a normal, safe, or economical consumer upgrade. For most owners, the correct answer is still to buy the higher-memory configuration, replace the motherboard, or choose a laptop with removable memory.
The first step is identifying what kind of memory your laptop has. “Soldered RAM” can describe discrete DRAM chips attached to the motherboard, memory integrated into the processor package, or a laptop that also has an unused SO-DIMM slot. Those designs have very different upgrade possibilities.

What kind of laptop memory do you have?
Use this classification before buying parts or opening the chassis:
| Design | What is physically present | Upgrade reality |
|---|---|---|
| SO-DIMM | One or more removable DDR4 or DDR5 laptop memory modules. | Easy upgrade: install a supported module or replace the existing modules according to the service manual. |
| Soldered memory plus a slot | A base amount of DRAM is attached to the board, with one or more unused SO-DIMM slots. | Conditional upgrade: add a module without replacing the soldered chips. Capacity, channel behavior, and maximum supported memory remain model-specific. |
| Discrete soldered DRAM | Individual LPDDR or DDR memory packages are soldered directly to the motherboard. | Professional board-level upgrade: a specialist may be able to replace the chips if the board, firmware, and replacement parts support the target configuration. |
| CAMM2 or LPCAMM2 | A removable low-power memory module secured to a compression connector rather than permanently soldered to the board. | User-replaceable: it combines some LPDDR5X characteristics with modular replacement, although the laptop must explicitly support it. |
| Memory-on-package | DRAM is integrated into the same package as the processor. | Practically non-upgradeable: the memory is not a separate motherboard component that a repair shop can sensibly swap. |
This is why both of the following statements can be true: a manufacturer can accurately say that a laptop’s memory is “not upgradeable,” while an electronics engineer can still replace discrete DRAM chips on a particular motherboard.
Why manufacturers solder memory in the first place
Soldering memory is not done for just one reason, and the engineering advantages do not eliminate the repairability trade-off.

- Shorter signal paths: placing memory close to the processor can make high-speed signaling easier to route.
- Less board area: removing sockets and their surrounding traces can simplify the motherboard layout.
- Thinner systems: the space saved may contribute to a slimmer chassis or leave room for a larger battery, cooling system, or other components.
- Fewer connectors: a soldered design eliminates the mechanical connector and some associated signal-routing requirements.
PCWorld’s technical explanation identifies thinness, power efficiency, and board-space savings as major reasons for using soldered LPDDR memory. Those benefits are real, but so is the cost: the buyer has to choose enough memory at purchase, and a failed memory chip may require board-level repair or a system-board replacement.
Low-power memory no longer has to be permanently soldered in every design. Micron describes LPCAMM2 as a modular approach intended to retain LPDDR5X benefits while enabling replacement. Micron reports up to 64% space savings and lower active and standby power than DDR5 SO-DIMM in its own comparison methodology; those are vendor measurements, not a universal independent performance guarantee.
The Dell XPS 13 7390 case that changed the answer
The clearest evidence that discrete soldered RAM can sometimes be upgraded is the Hackaday case study published on November 24, 2021. Engineer Greg Davill modified a Dell XPS 13 7390 that originally had 8GB and brought it to 16GB.
According to Davill’s technical write-up, the work involved:
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- Identifying the board’s LPDDR3 memory arrangement.
- Finding a compatible four-chip 16GB configuration using four 32Gbit ICs.
- Identifying the replacement part as
H9CCNNNCLGALAR-NVD. - Accounting for the target memory speed of 2133Mbps rather than simply choosing another chip labeled LPDDR3.
- Removing the original BGA packages with a preheater and hot air.
- Reballing the replacement packages with a stencil, solder balls, flux, and cleaning work.
- Changing a resistor strap used by the board to identify the memory configuration.
- Practicing on an older board before attempting the target laptop.
- Running four passes of MemTest86 without errors after the repair.
After the CMOS battery had been removed and reconnected, the modified laptop took approximately 30–60 seconds to boot. The BIOS reported 16GB, the operating system started, and the memory passed the documented test sequence. Davill nevertheless concluded that buying the 16GB version initially would have been preferable.
This is evidence of possibility, not a repeatable consumer procedure. It worked because the specific XPS platform had a higher-memory configuration to study, compatible chips could be identified, the board’s configuration straps could be understood, and the repairer had the equipment and experience to perform BGA rework.
Why this is not a normal RAM upgrade
With a SO-DIMM, you normally remove a retaining clip, insert a module, and let the platform read its specifications. With soldered DRAM, the memory packages are part of the motherboard’s electrical design. The operation is closer to repairing or modifying a populated circuit board than to upgrading a laptop.
The replacement chips must match far more than the memory label
“LPDDR4,” “LPDDR5X,” or “same speed” is not enough. A suitable replacement may need to match all of the following:

- Package type, physical footprint, and BGA ball count.
- Ball-map arrangement and pin compatibility.
- Density per package.
- Internal organization and data width.
- Operating voltage and signaling requirements.
- Supported data rate, timing, and training behavior.
- Channel and rank arrangement.
- Platform-specific or manufacturer-specific compatibility.
- BIOS, firmware-table, or resistor-strap support for the new capacity.
The XPS example illustrates the problem. A donor chip can be the same LPDDR generation and still be unsuitable: the original memory was rated at 1866Mbps, while the desired configuration called for 2133Mbps. The laptop’s schematic, boardview, memory datasheets, BIOS information, and a known higher-capacity board are much stronger evidence than a retailer listing that merely repeats a memory-generation name.

There is also a sourcing risk. Small quantities of high-density BGA DRAM may be expensive, unavailable, salvaged, remarked, or counterfeit. A chip can have the right printed markings and still be defective or electrically unsuitable.
The BIOS may need a configuration change
A removable SO-DIMM generally carries an SPD EEPROM that describes its capacity and operating characteristics. Soldered memory does not use a removable module in the same way, so the firmware may obtain equivalent information from board configuration, firmware tables, or platform-specific settings.
In the XPS 13 7390, Davill found five resistor straps connected to CPU GPIO lines. Those straps identified different memory configurations, and one had to be moved so the BIOS would recognize the 16GB arrangement.
That does not mean every soldered-memory laptop uses resistor straps. Depending on the platform, the capacity, density, vendor, timing, or organization may be determined by:
- Automatic memory detection and training.
- Resistor or GPIO configuration.
- BIOS tables or platform firmware.
- Memory-controller limitations.
- A fixed processor-package configuration.
A system may therefore fail to boot, train the memory incorrectly, run at a lower speed, or report the wrong configuration even when the replacement chips appear electrically similar. Conversely, a BIOS screen showing a larger capacity is not proof that every memory address works. In the XPS case, the BIOS could report the configured capacity based on the resistor straps without fully testing the memory, which is why extended diagnostics mattered.
How to identify your laptop’s memory design
Do this research before removing the bottom cover. Use the exact model, processor, display or regional configuration where relevant, and motherboard revision if it is available. Product families often contain several completely different memory designs.
1. Record the exact model in Windows
Press Win+R, type msinfo32, and press Enter. Microsoft documents msinfo32 as the Windows System Information command. Record the system model and processor rather than relying on a name such as “XPS 13,” “ThinkPad T16,” or “EliteBook.”
For additional memory-device information, open PowerShell and run:
Get-CimInstance Win32_PhysicalMemory | Format-Table BankLabel,DeviceLocator,Capacity,Speed,ConfiguredClockSpeed,Manufacturer,PartNumber,FormFactor,ReplaceableMicrosoft’s Win32_PhysicalMemory documentation describes properties such as capacity, speed, manufacturer, part number, form factor, and replaceability. This output is useful evidence, but it is not definitive. SMBIOS information can be incomplete or inaccurate, and a generic or empty device listing does not prove that the RAM is soldered.
2. Read the manufacturer’s exact specifications
Search the manufacturer’s support site for terms including:
- Memory slots
- Memory type
- Onboard memory
- Soldered memory
- Memory on package
- Customer accessible
- Upgradeable
- Service manual or hardware maintenance manual
- PSREF
Look for explicit wording, not assumptions based on the processor family. For example:
Recommended Free Tools
- Lenovo’s ThinkPad X13 Gen 7 Intel specifications list 16GB and 32GB soldered LPDDR5X configurations with no memory slots.
- HP’s EliteBook X G1a specifications describe LPDDR5X memory as non-accessible and non-upgradable.
- Dell’s Latitude 5455 documentation labels its memory onboard and integrated into the system board.
3. Check the service manual or an internal board photograph
A service manual may identify a SO-DIMM socket, an LPCAMM2 connector, or no serviceable memory component. Teardown photographs can help confirm what is physically present, but do not treat a photograph of one configuration as proof for every motherboard in the product family.

Do not infer that a memory device is removable merely because Windows lists it as a “physical memory” device. Conversely, do not infer that a laptop has no slot merely because software does not display one.
The important exception: soldered memory plus an unused slot
Some laptops solder a base amount of memory to the motherboard and provide one SO-DIMM slot for expansion. This is the best-case scenario for an owner because no BGA chip replacement is needed.
Lenovo’s ThinkPad T16 Gen 2 Intel specifications demonstrate why the exact configuration matters. They show:
- LPDDR5X models with all memory soldered and no slots.
- DDR4 models with 8GB soldered plus one SO-DIMM slot, supporting up to 40GB.
- DDR5 models with 16GB soldered plus one SO-DIMM slot, supporting up to 32GB.
Adding a module does not automatically guarantee ideal dual-channel performance. If the soldered and removable capacities do not match, the platform may use asymmetric or partially interleaved operation. The exact behavior depends on the processor and motherboard, so check the manufacturer’s supported configurations and service documentation before buying a module.
LPCAMM2: low-power memory that is actually replaceable
CAMM2 and LPCAMM2 are important because they challenge the assumption that efficient, high-speed LPDDR memory must be permanently soldered. An LPCAMM2 module is secured to a compression connector and can be removed, although the procedure is more involved than replacing a conventional SO-DIMM.
For example, Lenovo’s ThinkPad P1 Gen 7 specifications list one LPCAMM2 connector, dual-channel operation, up to 64GB of LPDDR5X-7500 memory, and a platform limit of up to 7467MT/s. Lenovo classifies the memory as upgradable.
Lenovo’s replacement instructions classify the CAMM2 module as a replaceable component and warn that memory replacement can trigger memory retraining. Follow the model-specific instructions, including the required power and battery precautions.

Framework’s Laptop 13 Pro also uses removable LPCAMM2 LPDDR5X memory rather than soldered-down memory. There is an important capacity discrepancy to check before buying: Framework’s product page advertises configurations up to 64GB, while its later knowledge-base material and replacement guide state support for one LPCAMM2 module up to 96GB at 7467MT/s. Verify the latest compatibility list and module availability before treating 96GB as a purchase option.
When soldered memory is actually inside the processor package
Some newer laptops do not have individual DRAM packages soldered near the processor. Instead, the memory is part of the processor package itself. This is a materially different and more restrictive design.
Intel’s Core Ultra 200V documentation describes integrated LPDDR5X memory on package and no external DDR interface. Intel lists 16GB and 32GB package configurations. Dell’s documentation for the Pro 13 Plus similarly states that the memory is integrated into the processor and is not upgradeable.
A board-level technician may be able to replace discrete BGA DRAM chips mounted on a motherboard. That does not mean the technician can separately upgrade memory integrated into a processor package. Treat the factory capacity of a memory-on-package laptop as permanent when choosing the machine.
What the XPS chip-level repair required
The XPS 13 7390 project is useful as a case study because it shows the hidden work behind a seemingly simple capacity change. It was not a matter of “soldering bigger chips” onto empty pads.
- Find a reference configuration. A higher-memory version of the same laptop or board provides evidence about supported chip density, layout, and firmware behavior.
- Identify the exact DRAM. The repairer used BIOS information and platform research to identify a target part rather than relying on a generic LPDDR3 listing.
- Understand board configuration. The XPS used resistor straps to identify the installed memory arrangement.
- Remove the packages without destroying the board. This requires controlled heating of a multilayer motherboard and protection of nearby components.
- Prepare the replacement packages. The chips must be properly reballed and inspected, with correct alignment and a compatible ball map.
- Reflow and inspect the joints. An open joint, bridge, misplaced package, or lifted pad can prevent booting or create intermittent faults.
- Configure and initialize the platform. The CMOS may need to be reset, and the first boot can take substantially longer while memory is retrained or initialized.
- Test beyond the BIOS screen. The XPS eventually passed four MemTest86 passes, which was much stronger evidence than simply seeing “16GB” in firmware.
Do not use this as a home repair recipe. A hot-air station alone is not a substitute for BGA experience, a preheater, microscope inspection, suitable stencils and reballing materials, board documentation, and a way to recover from a damaged motherboard. Practice on scrap boards does not eliminate the risk to the target laptop.

How to decide whether a professional upgrade makes sense
Recommend a normal user upgrade when:
- The service manual identifies a SO-DIMM slot.
- The laptop manufacturer lists a supported maximum capacity.
- The module type, speed, capacity, and voltage are documented.
- The installation follows the service guide.
- You have a current backup before opening the machine.
Consider professional chip-level rework only when nearly all of these are true:
- The exact laptop and motherboard revision are known.
- The laptop is valuable, specialized, or difficult to replace.
- A higher-memory version of the same board or platform exists.
- The original and replacement DRAM part numbers are documented and traceable.
- A schematic, boardview, BIOS table, or other board-level documentation is available.
- The BIOS is known to support the target configuration.
- The technician has professional BGA equipment and microscope inspection.
- The cost of losing the board is acceptable.
- Warranty coverage is no longer important, or the work has been explicitly authorized.
- The repair shop offers a meaningful warranty on its rework.
Advise against it when:
- The laptop uses memory-on-package.
- The processor supports only a fixed package configuration.
- No higher-memory version of the same board exists.
- The memory package, part number, voltage, organization, or electrical details cannot be verified.
- The available chips are untraceable, remarked, or untested salvaged parts.
- The motherboard is difficult to heat evenly or already has damage.
- The machine is still under warranty.
- The labor cost approaches the price of a higher-memory used laptop.
- The system contains important data without a verified backup.
- You have no BGA-rework experience.
Risks and failure modes
Even when the capacity appears in BIOS, the repair can still be unreliable. Typical technical failures include:
- Torn or lifted motherboard pads during chip removal.
- A warped PCB caused by excessive or uneven heat.
- Solder bridges or open BGA joints.
- Incomplete or uneven reballing.
- The wrong ball map or package variant.
- Counterfeit, remarked, or defective DRAM.
- An incorrect resistor-strap configuration.
- BIOS refusal to train or initialize the new memory.
- Memory running below its expected speed.
- Loss of dual-channel or interleaved operation.
- Damage to nearby components from hot air.
- Flux residue or solder debris left on the board.
- A failed boot after CMOS reset or battery reconnection.
- Intermittent crashes caused by one marginal memory chip.
The XPS write-up describes the difficulty of finding genuine chips, inspecting their authenticity, heating a multilayer board, and correcting imperfect BGA alignment. These are not edge cases; they are the reason the work belongs with a specialist.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Repair Windows errors before they cause bigger problems3Fix the driver behind crashes, sound loss and screen glitchesEconomic risks
Parts may be expensive or unavailable in small quantities. A repair shop may charge a diagnostic fee even if the board is unsuitable. If the board fails, you may still need a motherboard replacement. A successful memory modification also does not refresh an aging CPU, GPU, battery, display, keyboard, cooling system, or SSD, and it may reduce resale value because a buyer cannot easily verify the work.
Warranty implications
Opening a laptop does not automatically erase every warranty right in every country. The more accurate concern is that unauthorized modification or damage caused by the work may be excluded from coverage.
Dell’s U.S. limited hardware warranty excludes problems resulting from unauthorized servicing and components not supplied by Dell. HP’s warranty guidance says damage caused by self-repair, unauthorized repair or rework, modification, or soldering damage may not be covered.
Therefore, a RAM-chip modification may not legally or automatically void every aspect of a warranty, but it gives the manufacturer a strong basis to deny coverage for damage related to the modification. Check the exact warranty terms and local consumer-protection rules before proceeding.
Would replacing the motherboard be easier?
Sometimes a higher-memory motherboard is a more realistic alternative than replacing individual DRAM packages. It is still a complete system-board repair, not a simple RAM upgrade.
Before buying a replacement board, verify:
- Processor and GPU configuration.
- Display, battery, storage, port, keyboard, and chassis compatibility.
- BIOS and firmware requirements.
- Whether the replacement board is genuine and tested.
- Whether the board carries a serial number, Service Tag, or other device identity.
- Windows activation, enterprise management, and enrollment implications.
- Total cost compared with a higher-memory used laptop.
For example, Dell’s XPS 13 7390 service documentation notes that the Service Tag is stored on the system board and must be entered into BIOS after a system-board replacement. A board swap can therefore require identity, firmware, and licensing work in addition to the physical installation.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.How to verify a chip-level repair
A successful first boot is not enough. Use a staged validation process:
- Enter BIOS or UEFI and confirm the expected capacity.
- Boot the operating system and confirm the capacity and configured speed there.
- Run a bootable memory diagnostic.
- Allow multiple passes or an extended test period rather than relying on a quick check.
- Exercise the system with an appropriate demanding workload, such as compilation, virtual machines, or large memory allocations.
- Watch for freezes, application crashes, graphical corruption, kernel panics, unexplained reboots, and data corruption.
MemTest86 is a standalone USB-bootable diagnostic that tests RAM for faults and supports current memory technologies and form factors, including DDR5 and CAMM2. Its documentation also warns that not every reported failure originates in the RAM: a faulty CPU or motherboard can produce similar symptoms. A clean test is strong evidence, but it is not a substitute for diagnosing the entire platform if problems continue.

What a pagefile or “virtual RAM” can and cannot do
A pagefile or swap file is not a physical RAM upgrade. Windows can move less-active memory pages from RAM to storage, increasing the system’s commit limit. Microsoft describes that limit as the combination of physical RAM and page files in its page-file documentation.
A larger pagefile can prevent some out-of-memory failures, but it does not provide the bandwidth or latency of DRAM. Heavy paging can make a laptop feel extremely slow. A faster or larger SSD may make paging less painful, but it does not increase physical memory. “Virtual RAM,” “memory expansion,” and similar terms generally refer to storage-backed paging, not extra RAM chips.

Keep adequate free SSD space, let the operating system manage paging unless you have a specific reason to change it, and reduce memory demand where possible. These steps manage pressure; they do not create additional physical RAM.
Alternatives to replacing soldered chips
- Buy the higher-memory configuration. For a new laptop with fully soldered memory, this is usually the safest and cheapest lifetime decision.
- Use an existing SO-DIMM slot. A soldered base amount does not prevent a normal upgrade if the model includes a supported slot.
- Choose LPCAMM2. It offers a modern middle ground between soldered LPDDR-style memory and conventional SO-DIMM designs. Lenovo’s ThinkPad P1 Gen 7 and Framework’s Laptop 13 Pro are documented examples.
- Choose a laptop with SO-DIMM sockets. Business, workstation, gaming, and thicker performance laptops are more likely to retain removable memory, but verify the exact model rather than relying on the product category.
- Replace the motherboard. This can make sense when a compatible higher-memory board is inexpensive and readily available.
- Reduce memory demand. Close unused applications and browser tabs, reduce virtual machines or containers, disable unnecessary startup programs, use lighter software, and move unusually large workloads to a desktop, remote workstation, or cloud environment.
- Upgrade storage for paging responsiveness. This can improve storage performance when the system is forced to page, but it is not a substitute for more RAM.
Use this decision tree before spending money
- Find the exact model and board revision. Do not stop at a family name.
- Read the manufacturer’s specifications and service manual. Look specifically for slots, onboard memory, LPCAMM2, and memory-on-package language.
- If there is a SO-DIMM slot, perform the normal supported upgrade.
- If there is an LPCAMM2 connector, buy a documented compatible module and follow the service instructions.
- If all visible memory is discrete soldered DRAM, look for a higher-memory sibling configuration and board-level documentation.
- If the memory is integrated into the processor package, treat the installed capacity as fixed.
- Compare alternatives. Price the specialist repair, motherboard, and a higher-memory replacement laptop—including the cost of failure and lost warranty coverage.
Do not attempt a chip-level upgrade if…
- You have no BGA-rework experience, microscope, or controlled heating equipment.
- You cannot identify the exact replacement part and package variant.
- No higher-memory reference configuration or board documentation exists.
- The laptop is under warranty and the modification is unauthorized.
- The device contains irreplaceable data without a verified backup.
- The cost of failure is unacceptable.
- The repair quote is close to the price of a higher-memory replacement.
What common advice gets wrong
“Soldered RAM cannot be upgraded” is useful buying advice, but it is technically too broad. It fails to distinguish discrete BGA DRAM from memory-on-package and ignores laptops with soldered memory plus a slot.
Quick wins for a faster PC:
Clear out junk files and repair common Windows errorsFree Scan →Fix the driver behind crashes, sound loss and screen glitchesFind Drivers →Repair Windows errors before they cause bigger problemsFix Now →On the other hand, the XPS 13 case should not be generalized into “any soldered RAM can be upgraded.” It does not establish that every LPDDR generation uses the same configuration method, that a BIOS modification is always required, that a same-label chip will work, or that a hot-air station is sufficient. Nor does it apply to processor-package memory.
Likewise, “LPDDR is always soldered” is no longer correct because LPCAMM2 provides removable LPDDR5X-style memory. And “a larger pagefile gives you more RAM” confuses virtual-memory capacity with physical memory performance.
Bottom line
If your laptop has soldered RAM, first determine whether it actually has a removable SO-DIMM or LPCAMM2 module. If it has discrete DRAM chips on the motherboard, a qualified specialist may be able to replace them—but only after confirming the exact chips, firmware configuration, and board support. If the memory is integrated into the processor package, treat the factory capacity as permanent.
“Not user-upgradeable” is not always the same as “physically impossible,” but for most laptop owners it remains the correct buying advice.
Frequently Asked Questions
Can I add a RAM stick to a laptop with soldered memory?
Only if the laptop also has an unused, supported SO-DIMM slot. If every memory component is soldered, there is no slot into which a normal RAM stick can be inserted. A chip-level upgrade would require replacing the motherboard-mounted DRAM packages.
Is replacing soldered RAM worth the cost?
Usually not. It can make sense for a valuable or specialized laptop when a higher-memory reference configuration, genuine compatible chips, board documentation, and an experienced BGA-rework technician are all available. Compare the complete repair quote and failure risk with a motherboard swap or a higher-memory replacement laptop.
Does a larger pagefile give a laptop more RAM?
No. A pagefile increases virtual-memory commit capacity by using storage, but it is much slower than physical DRAM. It can prevent some out-of-memory errors, but it does not provide the speed or bandwidth of additional RAM.
Is LPCAMM2 the same as soldered RAM?
No. LPCAMM2 is a removable low-power memory module attached through a compression connector. It can provide LPDDR5X-style efficiency while remaining replaceable, but support and maximum capacity depend on the exact laptop.
The Bottom Line
Soldered laptop RAM is sometimes technically replaceable, but it is rarely a sensible user upgrade. Check for a SO-DIMM or LPCAMM2 module first. Discrete soldered DRAM may be a professional board-level repair; memory-on-package systems should be considered permanently fixed. When in doubt, buy the higher-memory configuration or choose a laptop designed for memory upgrades.
