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.

Questions about this item

Should I choose this 256GB kit or a different capacity for the Supermicro X14SDI-36C-SP3F?

This kit provides 256GB total as two 128GB modules, matching the board's DDR5 5600MHz PC5-44800 4Rx4 Registered ECC specification. Consult your motherboard manual for supported capacities and approved DIMM population order before deciding.

What does the DDR5 5600MHz rating mean once installed in the X14SDI-36C-SP3F?

The modules run at DDR5 5600 (PC5-44800) with CL46 latency at 1.1V. Registered architecture offloads the memory controller so every slot runs fully populated at rated speed, while ECC corrects single-bit errors on the fly.

Does the 288-pin RDIMM interface cap speed or capacity on this motherboard?

The 288-pin Registered RDIMM form factor is exactly what the X14SDI-36C-SP3F requires. It enables full-capacity population across all supported slots at the rated DDR5 5600MHz speed without downclocking.
