Verify DDR5 RDIMM slot availability and ECC support

Confirm your ASRock WRX90 WS EVO board has a free 288-pin DDR5 RDIMM slot and that the BIOS recognises ECC registered memory. The module runs at 1.1 V with a 2Rx4 organisation and CL40 latency, so the platform must support these parameters.

Suits professionals expanding ECC capacity on this

Ideal for IT staff adding 64 GB of registered ECC memory to an ASRock WRX90 WS EVO system. Not suited for builds requiring non-ECC unbuffered DIMMs, higher-speed DDR5 grades, or motherboards outside the validated compatibility list.
