512GB DDR4 2666 ECC RDIMM kit

This 512GB kit contains eight 64GB DDR4 2666MHz registered DIMMs with ECC and a CL19 latency. It runs at 1.2V and uses 288-pin 2Rx4 modules built with major OEM chips. The kit is validated for the ASRock Rack ROMED8-2T motherboard supporting AMD EPYC processors.

Server builders needing maximum registered capacity

This kit suits administrators upgrading an ASRock Rack ROMED8-2T platform to its full 512GB registered memory limit with ECC reliability. It is not for desktop PCs or workstations that require unbuffered UDIMM memory, nor for systems limited to lower densities or slower DDR4 speeds.

Eight-module 2Rx4 registered configuration

The decisive specification is the eight-module 2Rx4 registered layout delivering 512GB at DDR4 2666 with CL19 timing. This exact rank and density combination must match the motherboard qualified vendor list for the EPYC platform to initialise correctly.

Points forts
