DDR4 2666 ECC RDIMM kit

This 32 GB kit contains four 8 GB registered DDR4 modules that run at 2666 MT/s with CL19 latency. It is built for ASRock Rack ROMED8-2T motherboards that support AMD EPYC processors and require ECC registered memory.

32 GB capacity with ECC headroom

Four single-rank 1Rx8 modules provide 32 GB of error-correcting capacity for virtualization, database or file-server workloads. The registered design adds electrical buffering so the memory controller sees one load per module, but the kit stops at 2666 MT/s and CL19 so bandwidth-sensitive tasks may hit a ceiling.

288-pin registered fit for EPYC boards

The modules plug into standard 288-pin DDR4 RDIMM slots and operate at 1.2 V without a heat spreader. They need a motherboard that accepts registered ECC DIMMs and an EPYC-compatible platform; they will not work in consumer desktop boards that require unbuffered non-ECC memory.

Soalan tentang produk ini

Will the four 8 GB DDR4 2666 ECC RDIMM modules work alongside existing registered memory in an ASRock EPYC server?

Yes, each 1Rx8 module runs at 1.2 V with CL19 timing, so it will operate with other registered DDR4 ECC DIMMs of the same speed and voltage in the same platform.

How can I verify the kit is running at DDR4 2666 with ECC active after installation?

Check the BIOS memory information or use a tool such as dmidecode; it should report 32 GB total, 2666 MT/s, registered ECC, 1Rx8 organisation and CL19 latency.

What exactly ships in the box and is anything else required to use the memory?

The package contains four 8 GB DDR4 2666 ECC RDIMM modules (part number MR21300-818K4); no additional parts are needed for installation in a compatible ASRock EPYC motherboard.
