Exact-match server upgrade

This 128 GB kit provides two 64 GB DDR5 RDIMMs rated at 5600 MT/s with CL46 latency and 1.1 V operation. It is built specifically for the Supermicro X14SDI-36C-SP3F motherboard and uses registered ECC modules with a 2Rx4 organisation.

Installation notes

The 288-pin RDIMM form factor matches the board's DIMM slots exactly, so no adapter or converter is needed. Because the kit is rank- and voltage-matched to the platform, the memory controller recognises the full capacity at rated speed without manual tuning. The only common issue is ignoring the motherboard's required population order; always follow the manual's slot sequence when filling all channels.

DDR5 RDIMM limits

Registered DDR5 modules offload electrical load from the memory controller, allowing every slot to run fully populated at the rated data rate. ECC corrects single-bit errors on the fly, preventing silent data corruption in production workloads. The practical ceiling is the maximum capacity and population rules defined by the specific motherboard, which vary by model and BIOS revision.
