System-Specific DDR5 Kit for ASRock Rack

This 64GB kit contains two 32GB DDR5 UDIMM modules built for the ASRock Rack W680D4ID-2T/G5/X550 motherboard. It targets system integrators and administrators upgrading that specific platform with validated memory.

DDR5 UDIMM Interface Constraints

The 288-pin DDR5 UDIMM form factor fits only DDR5-compatible unbuffered slots. The non-ECC, unbuffered design excludes use in registered or ECC-required channels. Operation is fixed at 1.1V with CL46 latency at the rated 5600MT/s data rate.

64GB Capacity Decides Fit

The 64GB total capacity, delivered as two dual-rank 32GB modules, determines whether the target workload fits within available memory. Builds needing more capacity or ECC error correction must select a different kit validated for that motherboard.

Questions about this item

Should I choose the 2x32GB kit or look for a different capacity?

This kit provides 64GB total as two 32GB modules, matching the dual-channel layout of the ASRock Rack W680D4ID-2T/G5/X550 and filling two 288-pin DDR5 slots.

What does DDR5 5600 CL46 mean for actual system performance?

The modules run at 5600 MT/s with a CAS latency of 46 cycles at 1.1V, delivering the standard JEDEC data rate and timing for this platform without overclocking.

Is this DDR5 UDIMM kit limited by the motherboard's memory controller or the 288-pin interface?

The 288-pin DDR5 UDIMM form factor and 5600 MT/s rating are the native specification for the W680D4ID-2T/G5/X550, so the memory controller and slot interface both support the full rated speed.
