This page lists every non-ECC unbuffered desktop memory module (UDIMM) NEMIX RAM supplies — DDR5, DDR4 and DDR3 for desktop PCs, small-form-factor business desktops, gaming towers and workstation-class desktops that do not use ECC. Every listing is matched to real systems, so you can shop by the PC or motherboard you own instead of guessing at specifications.

What is on this page

Single modules from 4GB to 48GB (4GB, 8GB, 16GB, 24GB, 32GB and 48GB) in 1Rx8, 1Rx16 and 2Rx8 rank configurations, plus matched kits up to 192GB (4 × 48GB) and 256GB (8 × 32GB). Speeds run from DDR5-5600, DDR5-5200 and DDR5-4800 through DDR4-3200 to DDR4-2133 and DDR3-1600. Every module runs at its JEDEC standard speed, with no XMP or EXPO profile to set in the BIOS. Use Technology Speed, Module Density, Kit and Rank to narrow the list, or Shop by System Model to jump straight to modules matched to your desktop or motherboard.

Where desktop UDIMM is used

DDR5 UDIMM is commonly paired with Intel Core 12th, 13th and 14th Gen and Core Ultra 200S desktops and AMD Ryzen 7000, 8000 and 9000 (AM5) desktops. DDR4 UDIMM is commonly paired with Intel Core 6th to 14th Gen DDR4 boards and AMD Ryzen 1000 to 5000 (AM4). DDR3 UDIMM covers older Intel Core 2nd to 4th Gen and AMD AM3+ systems. Matched listings cover business desktops such as Lenovo ThinkCentre and Legion, Dell OptiPlex and Precision, and motherboards from ASUS, MSI, Gigabyte, ASRock and Supermicro.

Choosing the right desktop module

Match the generation first — DDR5, DDR4 and DDR3 are keyed differently and do not fit each other's slots. On DDR5 desktops, two modules (one per channel) usually run faster than four; if you need maximum capacity, a 2 × 48GB or 4 × 48GB kit is the cleanest route. Intel Core Ultra 200S boards that list DDR5-6400 CUDIMM also accept standard DDR5-5600 UDIMM. A faster module in a slower system clocks down to the system's speed, and mixed kits run at the speed of the slowest module. Non-ECC UDIMM and ECC UDIMM share the same slot shape but are not interchangeable on every platform — for ECC-capable workstations and entry servers, see DDR5 ECC UDIMM. If you are unsure, send us the system model or the OEM part number and we will confirm fitment before you order.
