32GB DDR4 ECC RDIMM kit for ASRock EPYC servers

This 32GB kit contains two 16GB DDR4 2933 registered DIMMs built for ASRock Rack ROMED8-2T motherboards. The modules run at 1.2V with CL21 latency and provide error-correcting code protection for data integrity. They are designed for server and workstation environments that require registered memory.

Sustained-load behaviour with registered ECC

Registered buffering reduces electrical load on the memory controller during continuous operation. ECC circuitry detects and corrects single-bit errors in real time without halting the system. The 2Rx8 organisation spreads accesses across two ranks per module for stable throughput under heavy multi-threaded workloads.

288-pin RDIMM form factor decides fit

Only systems that accept 288-pin DDR4 RDIMMs can use this kit. UDIMM, LRDIMM or SO-DIMM slots will not accept these modules. Verify the motherboard manual lists RDIMM support before purchase.

Questions about this item

How much power does the 1.2 V DDR4 kit draw when the server runs continuously?

Each module operates at 1.2 V, the standard DDR4 voltage, so total draw depends on the motherboard's power delivery and the EPYC CPU's memory controller load.

What motherboard slot and chipset must I already have for this 288-pin RDIMM kit to work?

You need an ASRock Rack ROMED8-2T or compatible board with DDR4 RDIMM slots and an AMD EPYC processor that supports registered ECC memory.

Will the CL21 2Rx8 modules run alongside older DDR4 ECC RDIMMs I keep in the other channels?

The kit runs at 2933 MT/s CL21; mixing ranks or latencies forces the system to the slowest common speed and may require manual BIOS tuning.
