Target System and Kit Composition

This 128GB kit contains four 32GB DDR5 5600 modules built for the ASRock Rack W680D4ID-2T/G5/X550 motherboard. It is intended for administrators or integrators who need maximum supported capacity on that platform. The modules run at 1.10V with CL46 latency and use a 2Rx8 organisation on a 288-pin UDIMM form factor.

Fit and Limitations

Buyers who want ECC error correction or registered buffering should look elsewhere because this kit is non-ECC and unbuffered. Systems that require a heat spreader for thermal management will not find one on these modules. The kit is validated only for the named ASRock Rack board; other platforms are not covered by the supplied compatibility data.

Deciding Specification

The definitive figure is the DDR5 5600 (PC5-44800) speed rating combined with the 2Rx8 rank configuration and 1.10V operating voltage. If the motherboard memory list calls for this exact speed, rank, and voltage the kit will install and operate as specified. Any deviation in those parameters means the modules are not the correct match.

Questions about this item

What motherboard is this 128 GB DDR5 5600 kit validated for?

The kit is qualified for the ASRock Rack W680D4ID-2T/G5/X550 motherboard, which provides four 288-pin DDR5 UDIMM slots running at up to 5600 MT/s.

Can I mix these 2Rx8 modules with single-rank DDR5 DIMMs already in the board?

Mixing 2Rx8 and 1Rx8 modules is possible if the motherboard firmware supports mixed-rank populations; install the new 32 GB sticks in the primary slots and keep existing DIMMs in the remaining slots.

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

Open BIOS or a tool such as CPU-Z and verify the memory frequency reads 5600 MHz and the CAS latency shows 46 cycles at the rated 1.10 V.
