Exact-match 1.5 TB DDR5 kit for Supermicro

This 12-module kit delivers 1.5 TB of DDR5 6400 registered ECC memory built for the Supermicro H14DSG-O-CPU motherboard. Each 128 GB RDIMM runs at 1.1 V with CL52 timing and a 2Rx4 organisation. The registered design lets every slot run fully populated at rated speed.

Verify DIMM population rules

Server and motherboard memory support varies by model. Consult the system or motherboard manual for supported capacities, approved DIMM population order, and installation steps before purchase. The 288-pin RDIMM form factor this board requires is not a UDIMM or SODIMM.

Registered ECC design prevents silent data

Registered architecture offloads the memory controller so all twelve slots operate at full capacity, while ECC catches and corrects single-bit errors on the fly. Major OEM Samsung, Micron, or Hynix chips populate modules without heat spreaders. Lifetime replacement warranty and US-based technical support back the kit.

Questions about this item

Does the 1.5TB kit include all 12 modules or do I need to buy extra DIMMs?

The kit contains twelve 128GB DDR5 6400 CL52 1.1V ECC registered RDIMMs, giving the full 1.5TB capacity in one package; no additional modules are required.

Should I choose the 12x128GB kit or a smaller capacity for my Supermicro H14DSG-O-CPU?

The 12x128GB kit matches the board's maximum supported population of twelve 2Rx4 registered DIMMs; select it when you need the full 1.5TB, otherwise pick a smaller kit that follows the same population rules.

Will the DDR5 6400 CL52 rating run at that speed once installed in the H14DSG-O-CPU?

The modules are spec-matched to the motherboard's memory controller, so the kit operates at DDR5 6400 with CL52 timings at 1.1V when populated according to the board's installation guide.
