NEMIX RAM
Six 64 GB DDR4 3200 ECC registered DIMMs deliver 384 GB for ThinkMate workstations
This 384GB kit contains six 64GB DDR4 3200 registered ECC modules built for the ThinkMate XF4-24S3 workstation. The 288-pin RDIMM form factor fits server-grade motherboards that require registered memory. It targets IT professionals upgrading mission-critical systems with validated compatibility.
The PC4-25600 standard caps transfer rates at 3200 MT/s with a CAS latency of 22. Each module uses a 4Rx4 organisation, so the memory controller must support quad-rank registered DIMMs. Registered buffering adds one clock cycle of address latency compared with unbuffered modules.
The kit delivers 384GB across six 64GB sticks, requiring six free DDR4 RDIMM slots on the target board. Systems with fewer than six slots or a lower per-slot limit cannot use the full kit. Buyers needing a smaller increment should select a lower-capacity kit.
