768GB DDR5 ECC RDIMM kit for ASRock Rack W890D8-2L2T
This 768GB kit contains eight 96GB registered DDR5 modules built for the ASRock Rack W890D8-2L2T motherboard. It targets servers and workstations that require error-correcting memory at high density. Each module operates at 1.1V with CL52 latency.
DDR5 6400 registered limits
The modules run at 6400MHz PC5-51200 using a 2Rx4 organisation and registered signalling. Registered DIMMs add a clock cycle of buffering, so the memory controller must support registered operation. ECC function requires a platform that enables error correction across the full 768GB capacity.
288-pin RDIMM build implications
The 288-pin RDIMM form factor fits standard DDR5 server slots without a heat spreader, leaving clearance for dense slot populations. Eight modules fill every channel on the target board, so airflow across the bare PCB becomes the primary cooling path. Buyers who need unbuffered UDIMMs or non-ECC memory cannot use this kit.

Questions about this item
Should I pick the 8-module 768 GB kit or a smaller capacity for my ASRock Rack W890D8-2L2T?
The 8 x 96 GB kit fills all eight DDR5 slots on the W890D8-2L2T and delivers the full 768 GB supported by the platform. Choose a smaller kit only if you need to leave slots open for future expansion.
What does the 6400 MT/s rating actually give me once the modules are installed?
The memory runs at 6400 MT/s with CL52 latency at 1.1 V, providing the maximum standard DDR5 throughput the W890D8-2L2T memory controller supports without overclocking.
How does the 288-pin DDR5 RDIMM interface limit performance on this board?
The 288-pin DDR5 RDIMM interface is the native socket for the W890D8-2L2T, so the 6400 MT/s CL52 modules operate at their rated speed without downclocking caused by socket mismatch.
