Showing 73 - 96 of 148 products

Memory upgrades for Thinkmate-branded systems. Each listing covers one Thinkmate model, using the memory type, speed and module size that system needs. The fastest way to find yours is to type the model number into the search bar at the top of the page, for example RAX-XS4-21S4, GPX-XS8-24S3-4GPU, TWX QS4-14R7 or VSX R5 760S4. The model number is on the system label and on your Thinkmate order confirmation.

GPX GPU servers and workstations: multi-GPU systems for AI training, inference, rendering and simulation.
STX storage servers: STX-NL nearline storage, STX-TN NAS servers and STX-WS Windows NAS. For other NAS brands, see NAS memory.
RAX rackmount servers: Intel Xeon and AMD EPYC rack servers.
VSX, HPX and SBGrid workstations: professional workstations, including SBGrid systems for structural biology and cryo-EM.
TWX tower servers: pedestal servers for offices, labs and branch sites.
HDX high-density and EDX edge servers: dense compute for clusters, and compact systems for edge sites.

Which memory does my Thinkmate system use?

DDR5 ECC RDIMM: most current systems, mostly DDR5-6400 and DDR5-5600. See DDR5 RDIMM.
DDR4 ECC RDIMM: earlier Xeon Scalable and EPYC systems, mostly DDR4-3200. See DDR4 RDIMM.
ECC UDIMM: single-socket entry servers, TWX towers and some workstations. Some also accept non-ECC; where they do, both listings are here. Choose one type; do not mix ECC and non-ECC. See DDR5 ECC UDIMM and DDR4 ECC UDIMM.

Match the module type (RDIMM or UDIMM) and generation (DDR4 or DDR5) to what is already installed, use identical modules, and populate every memory channel evenly on each processor for full bandwidth. A faster module runs at the speed the processor supports, which is normal. Not sure which module fits? Send us your Thinkmate model number or the part number of the module you have installed, and we will confirm the right module before you order.
