384GB DDR5 ECC RDIMM Kit

This kit delivers 384GB of DDR5-4800 Registered ECC memory in eight 48GB modules. It is built for servers and workstations that require maximum capacity with error correction and registered buffering. Each module runs at 1.1V with CL40 timing and uses a 288-pin RDIMM form factor. The kit is verified for the Supermicro H13SSL-N motherboard.

Suited for full-population server builds

This memory suits administrators upgrading a Supermicro H13SSL-N to its full supported capacity with matched modules. It is not for systems that accept only unbuffered UDIMMs or SODIMMs. It is not for platforms limited to lower densities or speeds. Buyers needing non-ECC or consumer form factors should look elsewhere.

Registered ECC with 2Rx8 organization

The registered architecture offloads the memory controller so all eight slots run stably at full capacity. ECC corrects single-bit errors in real time to prevent silent data corruption. The 2Rx8 rank structure and 1.1V operation match the motherboard's memory-population rules. Confirm your system manual for approved DIMM order before installation.

Questions about this item

Should I pick the 384GB kit or a smaller capacity for my Supermicro H13SSL-N?

The 384GB kit fills eight slots with 48GB modules so the board sees the full amount at DDR5-4800; choose a smaller kit only if your manual limits total capacity or requires a specific population order.

What does DDR5-4800 CL40 actually deliver in this server?

The modules run at 4800 MT/s with a CAS latency of 40 cycles at 1.1V, giving the bandwidth and timing the H13SSL-N memory controller expects for stable registered ECC operation.

How does the 288-pin RDIMM interface limit speed or capacity here?

The 288-pin registered DDR5 form factor is keyed for this motherboard; it supports the full 384GB across all eight slots at the rated 4800 MT/s without downclocking.
