256GB DDR4 ECC RDIMM kit

This 256GB kit supplies eight 32GB registered DIMMs built for THINKMATE VSX-R5-760S1 and VSX-R5-540RTP workstations. Each module runs at DDR4 3200 with CL22 latency and 1.20V operation. The registered design adds a buffer that reduces electrical load on the memory controller. It targets administrators who need maximum capacity in those specific platforms.

Sustained-load behaviour with registered ECC

Error-correcting code detects and corrects single-bit errors during continuous operation. The registered buffer stabilises signalling when all eight slots are populated. Modules use major OEM chips from Samsung, Micron or Hynix and are stress tested under load before shipping. This combination helps maintain data integrity during long compute jobs or virtualisation workloads.

DDR4 3200 interface limits

The PC4-25600 standard caps transfer rate at 3200 MT/s per pin across the 288-pin interface. Registered DIMMs add one clock cycle of buffering, which slightly increases latency versus unbuffered modules. Maximum capacity per module is 32GB with 2Rx8 organisation. Systems requiring higher bandwidth or greater per-slot density must move to a newer memory generation.

Questions about this item

Does the 1.2 V operating voltage keep heat and power draw low when all eight modules run continuously?

Yes, each 32 GB module runs at 1.20 V, so the full 256 GB kit draws minimal power and generates little heat even under sustained server workloads.

What must the ThinkMate VSX-R5-760S1 or VSX-R5-540RTP already provide for these 288-pin ECC RDIMMs to function?

The workstation needs DDR4 RDIMM slots that support registered ECC memory at 3200 MT/s and a memory controller able to address 2Rx8 modules across all eight channels.

Will the CL22 registered DIMMs work alongside any older DDR4 ECC RDIMMs I keep in the same ThinkMate system?

They can coexist if the older modules are also DDR4 registered ECC at 3200 MT/s; the system will run all sticks at the lowest common speed and latency.
