Short answer: Supermicro servers and server motherboards use ECC memory. Current X14, X13, H14 and H13 platforms take DDR5, mostly registered ECC (RDIMM); X12, H12 and X11 platforms take DDR4 RDIMM or LRDIMM; X10 systems (Xeon E5 v3/v4 and Xeon D-1500) take DDR4 RDIMM in 16GB and 32GB sizes; and Xeon E, EPYC 4004, Atom and embedded systems take ECC UDIMM or SODIMM. A Supermicro system takes the memory of the motherboard inside it. This guide shows how to read your model name and links to matching NEMIX RAM listings across 1,527 Supermicro motherboards, servers, GPU systems, storage servers, blades, IoT systems and workstations.
Find your Supermicro model first
On a motherboard, the model name is printed on the board, usually between the memory slots and the PCIe slots, and on the box. On a system, it is on the chassis label and in your order paperwork. The prefix tells you what you have: X boards are Intel (X14DBM-AP, X12SPT-G), H boards are AMD EPYC (H13SSL-NT), and A boards are Intel Atom (A2SDi-8C-HLN4F). The number after X or H is the generation. Systems start with SYS- (SuperServer, Intel), AS- (A+ Server, AMD), ARS- (ARM), SSG- / ASG- (storage), SBI- / SBA- (SuperBlade) or MBI- (MicroBlade).

Older X10 systems: Xeon E5 v3/v4 and Xeon D-1500
220 NEMIX RAM listings cover X10-generation SuperServer, TwinPro, FatTwin, GPU, storage and workstation systems (the number in the model name ends in 8, as in SYS-1028U, SYS-6028R or SYS-F628R3). These platforms take DDR4 ECC RDIMM, plus ECC or non-ECC UDIMM on Xeon D-1500 and X10SRA systems. Their memory controllers support 8Gb DRAM only, so we list 16GB and 32GB RDIMM and 8GB and 16GB UDIMM built on 8Gb DRAM; higher-density modules made with 16Gb DRAM are not listed for these systems. DDR4-3200 modules run at the system's rated speed (2400, 2133 or 1866 MT/s). Examples: SYS-1028U-TNRT+ · SYS-6028R-TR · SYS-2028TP-HC0R (TwinPro) · SYS-4028GR-TRT (GPU) · SSG-5018D8-AR12L (storage) · SYS-7048GR-TR (workstation) · SYS-E300-8D (IoT) · SYS-5018D-FN4T (ECC UDIMM).
Which type of memory does my Supermicro system use?
- ECC RDIMM: registered memory for Xeon Scalable, Xeon 6, Xeon W-3400 / W-2400 and EPYC servers and boards. See DDR5 RDIMM and DDR4 RDIMM.
- LRDIMM: load-reduced DDR4 for maximum capacity on supported X11, X12 and H12 platforms. See DDR4 LRDIMM. Do not mix with RDIMM.
- ECC UDIMM: unbuffered ECC for Xeon E, EPYC 4004 / 4005 and many embedded boards. See DDR5 ECC UDIMM and DDR4 ECC UDIMM.
- SODIMM and ECC SODIMM: compact modules for some Atom, Xeon D and MicroBlade designs. See ECC SODIMM.
Install identical modules and populate memory channels evenly on each processor for full bandwidth; faster modules run at the speed the platform supports.
Have a Supermicro part number instead?
If your quote or invoice lists a Supermicro memory part number rather than a system model, see Supermicro OEM part number memory. Thinkmate systems built on Supermicro platforms are listed under Thinkmate Supermicro memory.
Frequently asked questions
Which memory does my Supermicro motherboard or server use?
It depends on the motherboard generation. X14, X13, H14 and H13 boards take DDR5; X12, H12 and X11 boards take DDR4. Most Xeon Scalable, Xeon W-3400 and EPYC 9004 / 7003 platforms use registered ECC memory (RDIMM), while Xeon E, EPYC 4004 and many Atom and embedded boards use unbuffered ECC (ECC UDIMM) or SODIMM. A Supermicro system takes the memory of the motherboard inside it. Every NEMIX RAM listing names the exact module type.
Why are X10 systems offered only in 16GB and 32GB modules?
X10 systems use Intel Xeon E5-2600/1600 v3/v4 or Xeon D-1500 processors, whose memory controllers support DRAM chips up to 8Gb. Most 32GB 2Rx8, 64GB and 128GB DDR4 RDIMMs sold today use 16Gb chips, which these systems cannot use. We list 16GB and 32GB registered modules built on 8Gb DRAM, so every module on an X10 listing works with that platform.
Can I mix RDIMM and LRDIMM, or ECC and non-ECC modules?
No. Registered (RDIMM), load-reduced (LRDIMM) and unbuffered (UDIMM) modules cannot be mixed in one system, and ECC and non-ECC modules should not be mixed. Choose one type and use identical modules throughout.
My platform is rated for DDR4-2933 or DDR4-2666. Why is the listing DDR4-3200?
Faster modules run at the speed the platform supports. A DDR4-3200 RDIMM installed in a DDR4-2933 or DDR4-2666 system runs at that system's rated speed, and DDR4-3200 is the speed most widely available today.
How many modules should I install?
Install identical modules and fill memory channels evenly on each processor. Xeon Scalable and EPYC processors have six to twelve memory channels each, depending on generation, and bandwidth is highest with one module in every channel. Each listing shows the slot count and the maximum capacity for the board or system.
How do I order memory for a Twin or multi-node system?
Memory is listed per node. Order the configuration for one node and multiply by the number of nodes, filling every node the same way.
I have a Supermicro memory part number, not a model name. Where do I look?
Supermicro memory part numbers (for example MEM-DR532L-...) are cross-referenced in our Supermicro OEM part number collection. Search the part number at the top of any page.
Can I order memory for a rack, a cluster or multiple servers?
Yes. Purchase orders, net terms and volume pricing are available for data centers, hosting providers, integrators, research labs, universities, government buyers and resellers. Request a quote with your model list and quantities.
