NEMIX RAM 256GB (2x128GB) DDR5 5600MHz ECC Registered RDIMM Supermicro X14SDI-36C-SP3F

Exact-match server memory kit

This 256 GB kit contains two 128 GB DDR5 RDIMMs rated at 5600 MHz with CL46 latency and 1.1 V operation. Registered ECC architecture and 4Rx4 organisation let the Supermicro X14SDI-36C-SP3F motherboard recognise full capacity across both slots without down-clocking. The modules ship new and ready for immediate installation in compatible systems.

DDR5 RDIMM population limits

Registered DIMMs are required by this board; unbuffered UDIMMs or SODIMMs will not function in the 288-pin slots. Each channel supports a defined maximum rank count, so filling every socket with 4Rx4 modules works only when the memory controller and BIOS revision allow that density. Consult the motherboard manual for the approved population sequence and any per-channel rank ceiling before ordering.

4Rx4 rank density decides fit

The 4Rx4 organisation determines whether the memory controller can address the full 256 GB at the rated 5600 MHz speed. If the platform firmware or CPU revision caps rank-per-channel lower than this kit provides, the system will either reduce speed, halve usable capacity, or fail to post. Verify the exact rank limit for your specific processor and BIOS version prior to purchase.
