Showing 97 - 120 of 159 products

Memory upgrades matched to your Thinkmate system. Each listing on this page is built for a specific Thinkmate server, GPU system, storage server or workstation — or a Supermicro SuperServer sold by Thinkmate — using the memory type, speed and module size that platform needs. The fastest way to find yours is to type your Thinkmate model number, such as RAX-XS4-21S4, GPX-XS8-24S3-4GPU or STX-TN-XE24-24S3, into the search bar at the top of the page. The model number is on the system label and on your Thinkmate order confirmation.

Which type of memory does my Thinkmate system use?

Most Thinkmate servers and GPU systems use registered ECC memory, while entry servers and some workstations use unbuffered ECC memory. The two types are not interchangeable:

ECC RDIMM — registered server memory for Intel Xeon Scalable and AMD EPYC platforms. Current systems use DDR5 RDIMM (DDR5-4800 and faster); earlier generations use DDR4 RDIMM (mostly DDR4-3200).
LRDIMM — load-reduced modules for maximum capacity on supported DDR4 platforms. See DDR4 LRDIMM.
ECC UDIMM — unbuffered ECC memory for single-socket entry servers and workstations, such as Intel Xeon E systems. See DDR4 ECC UDIMM and DDR5 ECC UDIMM.

Listings on this page range from single 8GB modules to 256GB modules and multi-module kits.

How to choose Thinkmate memory

Match the module type (RDIMM, LRDIMM or ECC UDIMM) and generation (DDR4 or DDR5) to what is already installed, and do not mix RDIMM and LRDIMM in the same system. On multi-socket servers, populate every memory channel evenly on each processor for full bandwidth; on GPU systems, balanced channels matter most. 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.
