Exact-match DDR5-5600 kit for Supermicro H13SVW-N

This 256 GB kit (2 x 128 GB) delivers DDR5-5600 (PC5-44800) registered ECC memory built to the Supermicro H13SVW-N motherboard's required specifications. The 2Rx4 RDIMM modules run at 1.10 V with CL46 latency so the memory controller recognises full capacity at rated speed.

Straightforward 288-pin RDIMM installation

Modules seat in the board's 288-pin DDR5 RDIMM slots using the standard keyed notch; no heat spreader means tighter slot spacing is not an issue. Most problems come from ignoring the manual's population order or mixing ranks, which prevents the server from posting at full capacity.

Verify motherboard population rules before ordering

Check the Supermicro H13SVW-N manual for approved DIMM configurations, maximum capacity per slot, and the required installation sequence. This kit suits builds needing registered ECC DDR5; it does not fit boards that require UDIMM, SODIMM, or non-ECC modules.

Questions about this item

How can I confirm the kit is running at DDR5 5600 with CL46 after installation?

Enter the system BIOS or UEFI and verify the memory frequency shows 5600 MT/s with timings at CL46; the registered ECC design ensures the Supermicro H13SVW-N recognises both 128 GB modules at full rated speed.

What comes in the package and is anything else required for installation?

The box contains the 256 GB kit as two 128 GB 288-pin DDR5 RDIMMs; no additional parts are needed, simply install them into the approved DIMM slots on the H13SVW-N following the motherboard manual population order.

Should I choose this 2Rx4 256 GB kit or a different capacity for my H13SVW-N?

Select this 2Rx4 256 GB (2 x 128 GB) kit when your workload needs maximum registered ECC capacity per channel at 5600 MT/s; consult the board manual for supported population rules before deciding.
