Exact-match DDR5-6400 48GB RDIMM

This registered ECC module delivers 48GB at DDR5 6400 (PC5-51200) with CL52 timing at 1.1V. It is built for the Supermicro H13SSL-N motherboard and uses the 288-pin RDIMM form factor that board requires.

Registered buffer and on-die ECC

The registered architecture offloads the memory controller so every slot runs fully populated at rated speed. ECC catches and corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots in production workloads.

48GB per module with DDR5 headroom

A single 48GB 2Rx8 DIMM lets dense configurations scale without exceeding the board's supported population rules. Systems needing more capacity than the motherboard's maximum DIMM count allows will require higher-density modules.

Questions about this item

Will the 2Rx8 ECC RDIMM modules require any firmware updates or slot reconfiguration on the Supermicro H13SSL-N?

The modules are an exact-match upgrade built to the board's memory-population rules, so they are recognised at full capacity and rated speed without extra firmware steps.

What thermal limit appears first when the 48 GB DDR5 6400 kit runs continuously in a fully populated server?

Registered architecture offloads the memory controller, allowing every slot to run fully populated at full capacity without throttling under sustained load.

How much power does the 1.10 V registered ECC kit draw when the server runs all day?

Operating at 1.10 V, the DDR5 RDIMM modules draw minimal power while ECC corrects single-bit errors on the fly to prevent unplanned reboots.
