System-specific DDR5 kit for ASRock WRX90 WS EVO

This 256GB kit contains four 64GB DDR5 RDIMMs validated for the ASRock WRX90 WS EVO motherboard. Modules run at 4800MT/s with CL40 latency at 1.1V. Registered ECC design targets workstation and server workloads that require error correction.

Replaces non-ECC or lower-capacity DDR5

The jump is worth it when applications need registered ECC stability across four channels and total capacity beyond standard consumer limits. Systems already running DDR5 4800 without ECC or with fewer ranks gain data integrity and density without changing platform.

Fills four DDR5 RDIMM slots on the WRX90 WS EVO

Each module is a 288-pin 2Rx4 registered DIMM without a heat spreader, leaving clearance for CPU coolers. The kit occupies all slots for quad-channel operation at the rated speed. Buyers who need more than 256GB or non-registered memory cannot use this configuration.

Questions about this item

How many 288-pin DDR5 slots does the ASRock WRX90 WS EVO need free for this 4-module kit?

The kit contains four 64GB modules, so four DDR5 RDIMM slots must be available on the WRX90 WS EVO motherboard.

What BIOS setting should be checked after seating the 1.10V CL40 RDIMMs to confirm they run at 4800 MT/s?

Enter the BIOS and verify the memory frequency shows 4800 MT/s and the voltage reads 1.10V; enable any XMP or EXPO profile if the board offers one for registered ECC DIMMs.

When would a module in this 256GB ECC RDIMM kit typically need replacement?

Replace a module only if the system logs uncorrectable ECC errors or memory diagnostics report a persistent fault on a specific 64GB stick.
