NEMIX RAM
Eight 32 GB DDR5 ECC registered DIMMs deliver 256 GB at 6400 MHz with CL52 latency and 1.1 V operation for the Supermicro X14SDW-72C-SP9F
Size 256GB 8X32GB
This 256GB kit contains eight 32GB DDR5 registered DIMMs rated at 6400MT/s with CL52 latency and 1.1V operation. It is built for the Supermicro X14SDW-72C-SP9F motherboard and uses the 2Rx4 rank structure that board expects.
Registered buffering offloads the memory controller so every slot runs fully populated at rated speed without throttling. On-die ECC corrects single-bit errors in real time, preventing silent data corruption during continuous server workloads.
The 288-pin RDIMM form factor matches the board's keyed slots; insert each module until the latches click. Verify the manual's approved population order before installation to avoid a no-post condition.

Other versions of this model
Same family, different memory, cooler or clock — compare before you commit.
Each 32GB RDIMM operates at 1.1V with CL52 timings; the registered design offloads the memory controller so all eight slots run fully populated at rated speed without extra voltage overhead.
The board must provide DDR5 RDIMM slots that support 2Rx4 registered modules at PC5-51200; the kit matches the exact rank, voltage and timing the controller expects.
All populated slots must use identical 2Rx4 registered ECC modules at 1.1V and CL52; mixing different ranks, voltages or timings will prevent the server from recognising full capacity at rated speed.
