Memory upgrades for Intel server boards. Each listing covers one Intel board SKU, using the memory type, speed and module size that board takes. To find yours, type the board model into the search bar at the top of the page, for example M50FCP2SBSTD, M50CYP2SB1U, M20NTP2SB, S2600WFT, S2600CWTR or S1200SPLR. The model is printed on the board and on the box label.
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.
M50FCP family (32 slots per board or node): boards M50FCP2SBSTD.
3rd Gen Intel Xeon Scalable 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): boards M20NTP2SB.
M70KLP family (48 slots per board or node): boards M70KLP2SB. 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.
S2600WF family (24 slots per board or node): boards S2600WFO, S2600WFT.
S2600ST family (16 slots per board or node): boards S2600STB, S2600STQ.
Intel Xeon E5-2600 v3 and v4 platforms
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).
S2600WT family (24 slots per board or node): boards S2600WT, S2600WT2R.
DDR4 registered memory. The S7200AP has two listings: a 64GB DDR4-2666 LRDIMM, and 16GB and 32GB DDR4-2400 RDIMMs in kits of up to 6. Both run at the platform speed.
S7200AP family (6 slots per board or node): boards S7200AP.
Intel Xeon E3-1200 v5 and v6 platforms
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.
