1TB DDR5 RDIMM kit for ASRock Rack servers

This NEMIX RAM kit delivers 1 TB of DDR5 ECC registered memory across eight 128 GB modules. It is built for the ASRock Rack GNR2D16-2T motherboard and matches the exact rank, voltage and timing that board expects.

6400 MT/s CL52 at 1.1 V with full population

Running at DDR5-6400 (PC5-51200) with CL52 latency and 1.1 V, the 2Rx4 registered design lets every slot stay populated at rated speed. ECC corrects single-bit errors on the fly, preventing silent corruption in production workloads.

Replaces mixed-capacity or slower DDR5 kits

Swapping out partial fills or lower-speed modules removes population bottlenecks and restores full-channel bandwidth. The jump is worth it when your current configuration cannot reach 1 TB or forces down-clocking under load.

Questions about this item

Will the 128 GB DDR5 RDIMMs run at 6400 MHz alongside slower DDR5 modules I already have?

All populated slots must use identical 6400 MHz CL52 1.1 V registered ECC modules; mixing speeds or ranks forces the controller to down-clock every DIMM to the slowest common setting.

How can I verify the kit is operating at its rated 6400 MHz CL52 after installation?

Enter the UEFI or use a tool such as CPU-Z and confirm each DIMM reports DDR5-6400, CAS 52, 1.10 V and registered ECC status with no correctable errors logged.

Does the package include only the eight 128 GB RDIMMs or are heat spreaders and cables supplied too?

The kit contains exactly eight 288-pin DDR5 128 GB registered ECC RDIMMs; no heat spreaders, cables or additional accessories are included.
