Supermicro Memory: SuperServer, GPU, Storage, Blade, IoT Systems & Motherboards
Memory upgrades for Supermicro SuperServer and A+ systems, GPU servers, storage servers, SuperBlade and MicroBlade, IoT and embedded systems, SuperWorkstations and Supermicro motherboards. Listings are matched either to one Supermicro model or to one Supermicro memory part number, using the memory type, speed and module sizes Supermicro specifies. This page explains how to identify your Supermicro system and which memory it takes. To go straight to the products, type your Supermicro model or part number into the search bar at the top of the page.
Find your Supermicro model first
Systems carry a model name starting with SYS-, AS-, SSG-, ASG-, ARS- or SBI- on the system label (for example SYS-621C-TN12R or AS-4125GS-TNRT1). Motherboards carry a model starting with X (Intel) or H (AMD), printed on the board, for example X13DEI or H13SSL-N. The board generation decides the memory: X10 and X11 take DDR4, X12 and H12 take DDR4-3200, X13, H13, X14 and H14 take DDR5.

Which memory does my Supermicro system take?
- X14 and H14 (Intel Xeon 6, AMD EPYC 9005): DDR5-6400 RDIMM.
- X13 and H13 (4th and 5th Gen Intel Xeon Scalable, AMD EPYC 9004): DDR5-4800 or DDR5-5600 RDIMM; entry X13 and H13 boards take DDR5 ECC UDIMM.
- X12 and H12 (3rd Gen Intel Xeon Scalable, AMD EPYC 7002/7003): DDR4-3200 RDIMM or LRDIMM.
- X11 and H11 (Xeon Scalable, EPYC 7001, Xeon E, Atom): DDR4-2133 to DDR4-2933 RDIMM, LRDIMM or ECC UDIMM; X10 takes DDR4 or DDR3.
Rules that apply across Supermicro systems
- Registered or unbuffered, never both. Servers built on Xeon Scalable, Xeon 6, Xeon W-2400/3400 and AMD EPYC take registered memory (RDIMM or LRDIMM); entry servers on Xeon E, Xeon 6300, EPYC 4004 and similar take ECC unbuffered UDIMMs. Each listing names the type its system takes.
- Do not mix RDIMMs with LRDIMMs, or 3DS with standard RDIMMs, in the same system.
- Fill memory channels in matched groups of identical modules: six or eight per processor on Intel Xeon Scalable and Xeon 6, eight or twelve on AMD EPYC.
- Match the generation. DDR5, DDR4 and DDR3 modules are keyed differently and will not fit each other's slots.
- Speed follows the platform. Faster modules clock down automatically to the speed the processor and slot population support.
Ordering by Supermicro part number
Supermicro sells memory under part numbers starting with MEM-, for example MEM-DR532L-HL01-ER48. If you are adding to modules you already have or ordering from a Supermicro quote, search the part number or browse Supermicro part numbers. Each part-number listing is matched to the density, rank and speed of the original module.
Why NEMIX RAM for Supermicro memory
NEMIX RAM is a US-based server memory specialist, in business since 1993. Every module is researched, matched, and compatibility-tested by NEMIX RAM, is JEDEC-compliant, and is backed by a lifetime warranty. Each Supermicro listing names the exact model or part number it fits, so there is no guesswork about module type, speed or capacity.
Data centers, HPC sites and integrators
Purchase orders, net terms and volume pricing are available for data centers, HPC sites, research labs, universities, government buyers and resellers. Request a quote for a cluster, a rack refresh or a spares pool, or send us your model or part number and we will confirm the right module before you order.
Frequently asked
How do I tell which generation my Supermicro board is?
The first characters of the board model give it: X10, X11, X12, X13 or X14 for Intel; H11, H12, H13 or H14 for AMD. Systems list their board in the specifications.
Can I mix RDIMMs and LRDIMMs in a Supermicro server?
No. Use one type per system, and identical modules within each channel group.
Can I search by Supermicro part number?
Yes. Type the MEM- part number into the search bar at the top of the page.
