Server memory kit for EPYC platforms

This 256 GB kit contains four 64 GB DDR4 2400 LRDIMM modules built for ASRock Rack ROMED8-2T motherboards. It targets administrators who need maximum capacity in a single server chassis.

Load-reduced 4Rx4 organisation at 1.2 V

The modules use a 4Rx4 layout with ECC and operate at 1.2 V, a combination that only works on platforms qualified for DDR4 LRDIMM memory. Verify the motherboard QVL before ordering.

Standard JEDEC voltage keeps thermals predictable

At the rated 1.2 V the kit runs within normal DDR4 server power envelopes. No heat spreaders are fitted, so airflow across the DIMM slots determines operating temperature and acoustic profile.

Questions about this item

What does the 2400 MT/s rating mean once the kit is installed in the ASRock Rack ROMED8-2T?

The four 64 GB modules run at DDR4 2400 (PC4-19200) with CL17 latency, delivering 256 GB of ECC load-reduced capacity for the EPYC platform.

How does the 288-pin DDR4 LRDIMM interface limit performance on this board?

The 288-pin LRDIMM socket caps the kit at 2400 MT/s even though the motherboard supports up to 2666 MT/s.

What physical clearance does the 4Rx4 288-pin LRDIMM need in the server chassis?

Each 64 GB stick is a standard-height 288-pin LRDIMM with no heat spreader, so it fits the ROMED8-2T DIMM slots without extra clearance.
