Memory upgrades for Intel server systems. Each listing covers one Intel system SKU, using the memory type, speed and module size of the board inside it. To find yours, type the system model into the search bar at the top of the page, for example M50FCP2UR208, M50CYP1UR212, M20NTP1UR304, R2208WFTZS or R1304SPOSHOR. The model is on the system label on the chassis and on your order paperwork.
The board inside each system sets its memory: M50FCP, M50CYP, M20NTP and M70KLP systems use the Intel board of the same family, R1000WF and R2000WF systems use the S2600WF board, R1304WT systems use the S2600WT board, and R1208SP and R1304SP systems use the S1200SP board.
4th and 5th Gen Intel Xeon Scalable platforms
DDR5 registered memory (RDIMM) only; these listings are 16GB to 128GB DDR5-5600 ECC RDIMMs (PC5-44800, 1.1V). They 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. DDR4 modules do not fit these platforms.
DDR4 registered memory; these listings are 16GB to 128GB DDR4-3200 ECC RDIMMs (PC4-25600, 1.2V), which run at DDR4-3200, or at the processor's rated memory speed if that is lower.
M20NTP family (16 slots per board or node): server systems M20NTP1UR304.
M70KLP family (48 slots per board or node): server systems M70KLP4S2UHH. Four-socket platform: 12 slots per processor.
1st and 2nd Gen Intel Xeon Scalable platforms
DDR4 registered memory. Each model has two listings: a 64GB DDR4-2666 LRDIMM (PC4-21300, 4Rx4, 1.2V), and 16GB, 32GB and 64GB DDR4-2933 RDIMMs (PC4-23400, 1.2V) in kits; 64GB RDIMMs need 2nd Gen processors. Modules run at their rated speed, or at the processor's rated memory speed if that is lower.
DDR4 registered memory. Each model has two listings: a 64GB DDR4-2666 LRDIMM, and 16GB and 32GB DDR4-2400 RDIMMs (PC4-19200, 1.2V) in kits. Both run at the platform speed (DDR4-2400 with v4 processors, DDR4-2133 with v3).
DDR4 ECC unbuffered memory (ECC UDIMM) only, up to 64GB in 4 slots; these listings are 16GB DDR4-2666 ECC UDIMMs, which run at the platform speed. Registered and load-reduced modules do not work in these systems.
Do not mix LRDIMMs with RDIMMs, or registered modules with ECC UDIMMs, in the same system. DDR4 and DDR5 modules are keyed differently and are not interchangeable.
Install identical modules across each processor's memory channels for full bandwidth: groups of 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, four per processor on Xeon E5 v3/v4 boards, three per channel group on the S7200AP, and matched pairs on S1200SP boards.
Each listing names the exact module it fits. If you need a module type or size that is not listed for your platform, contact us before ordering.
