256GB DDR5 4800 ECC RDIMM kit

This 256GB kit contains four 64GB DDR5 4800 ECC registered DIMMs built for the Thinkmate GPX-QH12-12E4-2GPU server. Each module runs at 1.10V with CL40 latency and a 2Rx4 organisation using major OEM chips.

Suited for Thinkmate GPX-QH12 servers

It suits administrators expanding memory in that exact Thinkmate GPU-optimised platform where registered ECC DDR5 is required. Builders working with desktop boards, non-ECC platforms or systems that need unbuffered DIMMs should look elsewhere.

Registered ECC with 2Rx4 organisation

The single specification that decides fit is the registered ECC RDIMM design with 2Rx4 rank structure; only motherboards wired for registered DDR5 ECC at 4800 MT/s will accept these modules.

Questions about this item

Should I choose the 256GB kit with four 64GB modules or a different capacity?

This kit provides 256GB total using four 64GB DDR5 4800 CL40 ECC RDIMM modules at 1.1V, giving maximum density for the THINKMATE GPX-QH12-12E4-2GPU server.

What does DDR5 4800 speed mean for my server workloads?

The modules run at 4800 MT/s (PC5-38400) with CL40 latency and 2Rx4 organisation, delivering high bandwidth for GPU-optimised compute tasks on the supported THINKMATE platform.

How does the 288-pin ECC RDIMM interface affect compatibility and capacity limits?

The 288-pin DDR5 RDIMM form factor with registered ECC and 2Rx4 rank design is required by the THINKMATE GPX-QH12-12E4-2GPU motherboard; the four-module kit fills the validated configuration for 256GB.
