Intel Server Memory Guide: Server Boards, Server Systems & Compute Modules
Memory upgrades for Intel-branded server boards, server systems and compute modules. Every Intel listing at NEMIX RAM is matched to one Intel model and to the memory that platform takes: the right DDR5 or DDR4 module type, speed and size. This page explains how to identify your Intel platform, what memory each one uses and how to install it. To go straight to the products, shop all Intel server memory or type your Intel model number into the search bar at the top of the page.
Find your Intel model number first
Everything follows from the model number. On a board it is printed on the board itself and on the box label; on a rack system it is on the system label on the chassis; on a compute module it is on the module label. Your order paperwork carries it too. Intel model numbers follow a simple pattern:
| Example | What it is | Board inside |
|---|---|---|
| M50FCP2SBSTD, M50CYP2UR208, M20NTP1UR304 | Intel M-series board or system. The family name (M50FCP, M50CYP, M20NTP or M70KLP) comes first; "SB" marks a server board, and a system name gives its height, "1U" or "2U". | The Intel board of the same family |
| D50DNP1MHCPAC, D50TNP2MHSTAC | Module for the Intel FC2000 multi-node chassis: compute, management, storage or accelerator. | D50DNP or D50TNP |
| S2600WFT, S2600CWTR, S1200SPLR | Server board: "S" plus the board family, then letters that name the board variant. | Itself |
| R2208WFTZS, R1304WT2GS, R1304SPOSHOR | Rack server system. "R1" is a 1U system and "R2" a 2U system; the letters after the drive-bay digits name the board family (WF, WT or SP). | S2600WF, S2600WT or S1200SP |
| HNS2600BPB, HNS2600TPFR, S9248WK1HLC | Compute module: one node of a multi-node chassis. | S2600BP, S2600TP or S9200WK |
A rack system takes the same memory as the board inside it, so an M50FCP2UR208 uses the same DDR5 memory as the M50FCP2SBSTD board, an R2208WFTZS uses S2600WF memory and an R1304SPOSHOR uses S1200SP memory.
Memory by Intel platform
The M50FCP and D50DNP families use DDR5; every other platform on this page uses DDR4. The older S2600, S7200AP, S9200WK, R1000/R2000 and HNS2600 models each have two listings, a 64GB LRDIMM and an RDIMM listing with kits. Capacity shows what a fully populated board or node holds using the largest NEMIX module listed for that platform.

Rules that apply across every Intel platform here
- DDR5 or DDR4, by platform. M50FCP and D50DNP platforms take DDR5 only. Every other platform on this page takes DDR4. The two are keyed differently and will not fit each other's slots.
- Registered or unbuffered, never both. The S1200SP family (and the R1208SP and R1304SP systems based on it) takes ECC unbuffered memory (ECC UDIMM) only. Every other platform on this page takes registered memory.
- Do not mix LRDIMMs and RDIMMs in the same system. If your server already has RDIMMs installed, replace them all or match what is there.
- Install identical modules in matched groups. Eight per processor on 3rd, 4th and 5th Gen Xeon Scalable platforms (M50CYP, M50FCP, M20NTP, D50TNP, D50DNP), six per processor on the M70KLP and on 1st and 2nd Gen Xeon Scalable boards (S2600WF, S2600ST, S2600BP), four per processor on Xeon E5 v3/v4 boards (S2600WT, S2600CW, S2600TP, S2600KP), three per memory controller on the S7200AP, and pairs on the S1200SP. S9200WK compute modules take identical modules in groups of 8, 16 or 24.
- Speed follows the processor. DDR4 modules run at their rated speed or at the processor's rated memory speed if that is lower: DDR4-2400 with Xeon E5 v4, DDR4-2133 with Xeon E5 v3, and 2933 or 2666 MT/s with 3rd Gen Xeon Gold 5300 or Silver 4300 processors. DDR5-5600 modules run at 5600 MT/s with 5th Gen processors and 4800 MT/s with 4th Gen at one module per channel, and at up to 4400 MT/s at two modules per channel.
- Compute modules do not share memory. Each node in a multi-node chassis has its own slots and needs its own set of modules, including the D50DNP and D50TNP management, storage and accelerator modules in the FC2000 chassis.

Why NEMIX RAM for Intel server 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 Intel listing names the exact board, system or compute module it fits, so there is no guesswork about module type or speed.
Clusters, labs and data centers
Intel M50 and S2600 servers and FC2000 and HNS2600 multi-node compute modules run in HPC clusters, research labs, universities and hosting fleets. Purchase orders, net terms and volume pricing are available for data centers, government buyers and resellers as well. Request a quote for a full cluster, a rack refresh or a spares pool.
Frequently asked
Can I use DDR4 memory in an M50FCP or D50DNP system?
No. M50FCP and D50DNP platforms take DDR5 RDIMMs only. The M50CYP, M20NTP, M70KLP and D50TNP platforms take DDR4.
How much memory does an M50CYP or M50FCP system hold?
Both have 32 slots. With 128GB NEMIX RDIMMs in every slot that is 4TB; Intel lists up to 8TB using 256GB modules.
Will a DDR4-2666 module work in a board rated for DDR4-2400?
Yes. DDR4 memory runs at the highest speed both the module and the processor support, so a DDR4-2666 module runs at DDR4-2400 in a Xeon E5 v4 system.
Can I add 64GB LRDIMMs to a server that already has RDIMMs?
No. LRDIMMs and RDIMMs cannot be mixed in the same system. Either replace the existing modules or add matching RDIMMs: every S2600, S7200AP, R1000, R2000, HNS2600 and S9200WK model on this page also has an RDIMM listing, linked in the table above and from each LRDIMM listing.
Does the S1200SP take registered server memory?
No. S1200SP boards and the R1208SP and R1304SP systems take ECC unbuffered DIMMs (ECC UDIMM) only, up to 16GB per slot and 64GB in total.
How much memory does a multi-node chassis need?
Each compute module is populated separately. A chassis with four HNS2600TP nodes needs four sets of modules, one per node.
