System-specific DDR5 ECC kit

This 64 GB kit contains two 32 GB DDR5 5600 modules built for the ASRock Rack W680D4U-2L2T/G5 motherboard. Each unbuffered UDIMM runs at 1.1 V with CL46 latency and 2Rx8 organisation. The 288-pin design fits the board's native DDR5 slots.

Suited for ECC server builds

Buyers adding error-correcting memory to the named ASRock Rack platform will match the validated specification. Systems that require registered DIMMs, non-ECC modules, or a different DDR generation cannot use this kit.

Verify slot count and population rules

Confirm the motherboard has enough free 288-pin DDR5 sockets for two modules and check the manual for approved population order. Ensure the BIOS recognises 2Rx8 unbuffered ECC at the rated speed before ordering.

Questions about this item

What motherboard must I already have for this 288-pin DDR5 ECC UDIMM kit to work?

The kit is validated for the ASRock Rack W680D4U-2L2T/G5 motherboard, which provides the 288-pin DDR5 slots and ECC unbuffered support these modules require.

Can I keep my existing DDR5 4800 modules and add this CL46 5600 kit alongside them?

Mixing speeds will force all modules to run at the lowest common speed and latency; the board will down-clock this kit to match the slower 4800 modules.

How do I confirm the kit is running at 5600 MT/s with CL46 after installation?

Open the BIOS memory information screen or use a system-information utility; both will display the configured data rate and CAS latency for each installed module.
