  • Rated speedDDR4 3200 (PC4 25600)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL22
  • Buffer typeRegistered
  • Rated voltage1.2 V
  • Massive 768 GB capacity handles extreme server workloads
  • Six 128 GB modules populate all channels for peak bandwidth
  • DDR4 3200 speed delivers 25 600 MT/s data throughput
  • ECC registered design corrects errors and stabilises heavy loads
  • Low 1.20 V operation reduces power draw in dense configurations

Server-grade capacity

This 768 GB kit contains six 128 GB DDR4 3200 RDIMM modules built for THINKMATE GPX-XS12-24S3-8GPU servers. Each module is registered, ECC-enabled and organised as 4Rx4 to maintain data integrity under sustained loads. The 1.20 V operating voltage matches the platform specification.

DDR4 3200 interface limits

The PC4-25600 standard tops out at 3200 MT/s with CL22 timing, so bandwidth and latency are fixed by the memory controller. Registered buffering adds one cycle of command delay but allows the platform to populate all slots without signal degradation. No higher speed or lower latency is available within this DDR4 generation.

768 GB headroom

Six ranks of 4Rx4 DRAM per module give the maximum density this platform supports, letting large GPU-accelerated workloads, virtualisation fleets or in-memory databases run without paging. Once the six slots are filled, further expansion requires a different server chassis or motherboard.

Questions about this item

Should I pick the 6-module kit or buy single 128 GB sticks for my Thinkmate server?

The kit supplies six matched 128 GB modules for a total of 768 GB; mixing loose sticks can break quad-channel balance and ECC integrity.

What does DDR4 3200 CL22 actually deliver inside a GPU-optimised Thinkmate box?

At 3200 MT/s with CL22 timing the modules run at the server's rated bus speed, giving full registered ECC bandwidth for 24 GPU workloads.

Does the 288-pin RDIMM interface limit how fast the memory can run in this platform?

The 288-pin registered DDR4 slot caps at the platform's 3200 MT/s spec; the kit operates at that ceiling with 1.20 V and 4Rx4 organisation.
