Targeted server upgrade

This 64 GB kit delivers two 32 GB DDR4 3200 ECC registered DIMMs built for the ASRock Rack EPYCD8-2T series. It addresses administrators who need to expand memory capacity on qualified server boards without mixing unvalidated modules.

Registered ECC stability

Each module uses a 288-pin RDIMM form factor with a 2Rx4 organisation and operates at 1.2 V. The registered buffer and on-die ECC reduce electrical load on the memory controller and correct single-bit errors, supporting continuous operation in multi-DIMM configurations.

Ready-to-install kit

The package supplies a matched pair of 32 GB sticks under part number MR25600-324K2, eliminating the need to source identical modules separately. Major-brand Samsung, Micron or Hynix ICs ensure consistent quality across the kit for straightforward installation.

Questions about this item

What does the DDR4 3200 PC4-25600 interface cap the transfer rate at?

The DDR4 3200 PC4-25600 interface caps the theoretical maximum transfer rate at 25,600 MB/s.

What physical slot and pin count does this 288-pin RDIMM kit require on the ASRock EPYCD8-2T motherboard?

The kit requires two DDR4 RDIMM slots with 288 pins each on the ASRock EPYCD8-2T motherboard.

How are these ECC registered modules installed, and which step is commonly missed?

Install by aligning the notch on each 288-pin module with the slot key, pressing down firmly until the retention clips click; the step often missed is ensuring both clips lock fully to register the ECC RDIMM correctly.
