Capacity and fit

This 256GB kit contains eight 32GB DDR4 3200 modules built for ThinkMate Supermicro SuperServer 510P-M and 510P-MR platforms. Registered ECC RDIMM layout and 2Rx4 organisation suit multi-socket servers and workstations that require error-correcting memory at scale.

Sustained-load behaviour

Modules run at 1.2V with CL22 latency and PC4-25600 bandwidth, giving stable throughput during long compute or virtualization sessions. Major-brand Samsung, Micron or Hynix DRAM and factory stress testing under load reduce the chance of correctable errors accumulating over time.

Build and connectors

Bare 288-pin RDIMM sticks without heat spreaders keep the profile low for dense DIMM layouts and simplify cleaning in rack chassis. Registered buffering eases electrical load on the memory controller, helping reliability when all eight slots are populated.

Questions about this item

How much power does the 256GB kit draw at its 1.2V rating during continuous server workloads?

Each 32GB module operates at 1.2V, so the full 8-module kit runs at standard DDR4 voltage without elevated power draw.

What motherboard feature is required to use these 2Rx4 registered ECC RDIMMs?

The board must support DDR4 registered ECC memory with 288-pin RDIMM slots and 2Rx4 organisation.

Will these CL22 3200MHz modules run stably in a ThinkMate Supermicro 510P-MR alongside older DDR4 DIMMs?

They are validated for the 510P-M and 510P-MR; mixing ranks or speeds may force the system to the lowest common timing.
