Server Memory Kit

This 128GB kit contains four 32GB DDR4 RDIMM modules built for registered ECC server platforms. It targets administrators upgrading ASRock Rack ROMED8-2T motherboards running AMD EPYC processors. The registered design and error-correcting code suit workloads that demand data integrity over raw latency.

Registered ECC Build

Each module uses a 2Rx4 organisation with major OEM chips from Samsung, Micron or Hynix and operates at 1.20V without a heat spreader. The 288-pin RDIMM form factor fits standard DDR4 server slots, while the registered buffer reduces electrical load on the memory controller during heavy multi-DIMM population.

DDR4 2400 Speed

Rated at DDR4 2400 (PC4-19200) with CL17 latency, this kit matches the motherboard's supported memory speed for stable operation. Builders needing DDR4 2666 or higher frequencies, or non-ECC unbuffered DIMMs for consumer boards, should select a different product.
