NUC stands for Next Unit of Computing, Intel's name for its small-form-factor PCs. Intel's NUC line is now supported by ASUS, and ASUS has since built its own NUC, ROG NUC and ExpertCenter mini PCs, while ASRock makes a long line of DeskMini, DeskMeet and other mini PCs. This guide explains what memory these small systems use, how to match your model to the right module, and which ones cannot be upgraded at all.
The short answer
Almost every NUC and most mini PCs use SODIMM, the compact laptop-size module, in non-ECC form. The generation has to match your system exactly. A DDR4 system takes DDR4 SODIMM, a DDR5 system takes DDR5 SODIMM, and the two are not interchangeable. The main exceptions are the ASRock DeskMeet and DeskSlim, which take full-size desktop UDIMM, and a small group of models with memory soldered to the board.
Find your exact model first
Mini PC names are close to each other, so confirm the model before you order. The model name and code are on the label under the system and on your order paperwork. Examples are NUC 14 Pro, NUC14RVH, NUC 11 Pro, NUC11TNH, ExpertCenter PN64, Chromebox 5 and ASRock DeskMini X300. Each NEMIX listing covers one model or family of models, so searching the model name or code on the ASUS NUC and mini PC collection or the ASRock mini PC collection takes you straight to the right module.
ASUS and Intel NUC memory by family
The ASUS NUC and mini PC collection has 46 listings covering Intel NUC 7 through NUC 13, ASUS NUC 12 through NUC 16, ROG NUC, ExpertCenter PN, PB and PL mini PCs, Chromebox and the ROG GR70. Every listing is non-ECC SODIMM, and the speed shown is the one NEMIX lists for that model. Starting prices on October 27, 2026 were $56.99 for DDR4 SODIMM and $149.99 for DDR5 SODIMM.
The generation gap is easy to see in the table. Intel NUC 7 through NUC 13 Pro and the earlier ExpertCenter models are DDR4. From the NUC 13 Extreme onward, and on newer ExpertCenter models, the memory is DDR5. If you are not sure which side of that line your NUC is on, the listing that matches your model name settles it.
ASRock mini PC memory
The ASRock mini PC collection has 40 listings. Most ASRock mini PCs use SODIMM like the NUC family, but the DeskMeet and DeskSlim are slightly larger and take full-size desktop modules, so check the type column before you order.
| ASRock family | Listings | Memory |
|---|---|---|
| DeskMini | 15 | SODIMM, DDR4 on most models and DDR5 on the X600 and B860 models |
| Jupiter | 9 | SODIMM, DDR4 on most models and DDR5 on the X600 |
| Mars | 5 | SODIMM, DDR4 on most models and DDR5 on the RPL model |
| Beebox-S | 2 | DDR4 SODIMM |
| DeskMeet | 6 | Full-size UDIMM, DDR4 or DDR5, with ECC UDIMM listings on some models |
| DeskSlim | 3 | Full-size DDR5 UDIMM, with an ECC UDIMM listing on one model |
Where ASRock supports ECC on a model, an ECC UDIMM listing sits beside the non-ECC one. If your ASRock model is not listed, send us the model name and we will check it.
Models that cannot be upgraded
A few small systems use memory soldered to the board, so there is no slot to fill. The NUC 14 Pro AI, the ASUS Ascent GX10 and the Chromebox CF40 are examples, and they are not listed. If your spec sheet says LPDDR5X or memory down, the memory is on the board. Send us the model name and we will tell you whether it has a slot.
How to choose capacity
- Check your slot count. Most models have two SODIMM slots, which lets you fit two matched modules for dual-channel memory. A few models have a single slot, among them the NUC 16, NUC 14 Essential, PN42 and PN43, according to ASUS specifications, so a pair does not apply to them.
- Match the modules. When you fill both slots, use two identical modules for the most reliable result.
- Do not exceed the maker's maximum. Each NEMIX listing is built to the maximum published for the model, so the sizes offered on your listing are the safe options.
- Size for the job. Office and light desktop use is comfortable at 16GB. Virtual machines, development work, video editing and signage players with heavy content benefit from 32GB or more where the model allows it.
How to install SODIMM memory in a mini PC
- Shut down and unplug the system, then wait a moment for it to power off fully.
- Open the case. The method differs by model, usually a bottom cover or a top panel held by screws. Use the maker's service guide for your model.
- Find the SODIMM slots and remove the existing module by releasing the side clips, which makes it spring up at an angle.
- Insert the new module at an angle with the notch aligned, then press it down until the clips lock.
- Close the case, reconnect and power on. The system reports the new total at startup or in the operating system.
The same steps apply to the ASRock DeskMeet and DeskSlim, except that full-size UDIMM modules seat straight down into long slots.

Frequently asked questions
What kind of memory does a NUC use?
Most NUC models use non-ECC SODIMM. The generation depends on the model, with DDR4 on the older Intel NUC and earlier ASUS models and DDR5 on the newer ones.
Can I use desktop memory in a NUC?
No. NUC systems take SODIMM modules, which are physically shorter than the full-size modules used in desktops. The ASRock DeskMeet and DeskSlim are the exception because they take full-size UDIMM.
Can I put DDR5 memory in a DDR4 mini PC?
No. DDR4 and DDR5 modules have different notch positions and electrical requirements, so each generation only fits and works in a system built for it.
Do I need to match speeds and sizes?
Use two identical modules when you fill both slots. If speeds differ, the system runs the modules at the slower speed, and mixed sizes can reduce performance, so matching modules is the safest choice.
Why is my model not listed?
Some small systems have memory soldered to the board and no slot, so they cannot be upgraded. If your model is not listed, send us the name and we will check it.
Does my mini PC take ECC memory, and what is the maximum RAM?
Most NUCs and mini PCs take non-ECC SODIMM. ECC only works on the few models whose specification sheet lists ECC support, and Intel notes that the same sheet states the maximum capacity and the maximum number of modules. Look up your exact model there before you order, and send us the model name if you want us to check it.
