NEMIX RAM 128GB DDR4 ECC LRDIMM Kit

This 128GB kit contains two 64GB DDR4 2933 PC4-23400 modules built for server platforms. Each stick runs at 1.2V with CL21 latency and uses a 288-pin load-reduced ECC design. The 4Rx4 organisation suits high-density memory channels on compatible ASRock Rack EPYC motherboards.

Upgrade from lower-capacity or non-LRDIMM memory

Replacing smaller RDIMM or UDIMM modules with this 2x64GB LRDIMM kit increases total system memory while reducing electrical load per channel. The jump is worth it when your workload demands maximum supported capacity per slot and the motherboard qualifies load-reduced ECC at 2933 MT/s.

Verify motherboard qualification

Confirm the ASRock Rack ROMED8-2T or target board lists ML23400-944K2 on its qualified vendor list for 2933 MT/s operation. Check the manual for supported ranks per channel and required slot filling order before installing the 4Rx4 modules.

Questions about this item

Will the 288-pin DDR4 LRDIMM modules fit the ASRock Rack ROMED8-2T motherboard slots?

Yes, the 288-pin DDR4 LRDIMM form factor matches the memory slots on the ASRock Rack ROMED8-2T motherboard for AMD EPYC processors.

What is the correct way to install the 2x64GB kit, and what step is often missed?

Insert both 64GB modules into the correct channel slots per the motherboard manual, press firmly until the retention clips click, and ensure the BIOS recognises the full 128GB at 2933 MT/s.

Will the Samsung, Micron or Hynix DRAM chips on these LRDIMMs need replacement under normal server workloads?

The modules use major OEM chips from Samsung, Micron or Hynix and are stress-tested for reliability; no scheduled replacement is required during the product lifetime.
