64 GB DDR4 ECC UDIMM kit

This NEMIX RAM kit provides 64 GB of DDR4 2666 memory as four 16 GB unbuffered ECC UDIMMs. It runs at 1.2 V with CL19 latency and uses a 2Rx8 organisation. The modules are built with major-brand chips and carry a lifetime replacement guarantee.

Workstation builders needing ECC reliability

The kit suits professionals who require error-correcting memory for data integrity on the ASUS WS C246M PRO or WS C246M PRO/SE motherboards. It is not for systems that only accept registered DIMMs, SO-DIMMs, or non-ECC modules.

288-pin unbuffered ECC form factor

The single specification that decides fitment is the 288-pin unbuffered ECC UDIMM design matched to the board's DDR4 2666 population rules. Verified compatibility with the ASUS WS C246M PRO and WS C246M PRO/SE ensures recognition at full capacity and rated speed.

Questions about this item

Should I choose the 64GB kit of four 16GB modules or a different capacity?

The 64GB kit provides four 16GB DDR4 2666 UDIMMs that match the ASUS WS C246M PRO and PRO/SE memory population rules; select it when your workload needs the full 64GB at the board's rated speed.

What does the DDR4 2666 (PC4-21300) rating mean once the modules are installed in the workstation?

The memory will run at 2666 MT/s with CL19 timing at 1.20V, delivering the exact bandwidth and latency the C246 chipset expects for error-correcting workloads.

Does the 288-pin UDIMM interface limit the maximum speed or capacity on this motherboard?

The 288-pin unbuffered ECC UDIMM form factor is the only type the WS C246M PRO and PRO/SE accept, so the kit operates at the board's native DDR4 2666 limit without registration overhead.
