Server-grade DDR5 memory kit

This NEMIX RAM kit delivers 384 GB across eight 48 GB DDR5-5600 RDIMMs. Each module is a 2Rx8 registered ECC part running at 1.1 V with CL46 timing, built for the Supermicro H13SSH-E motherboard. It targets administrators expanding capacity on that specific platform.

Verify board population rules first

The H13SSH-E manual defines supported capacities, approved DIMM order, and installation steps. Memory controllers vary by revision, so confirm the exact population sequence before ordering. Eight-slot kits require every slot to match the board's qualified list for full-speed operation.

Registered ECC design offloads the controller

Registered architecture buffers address and command signals so the memory controller drives all eight slots cleanly at rated speed. ECC corrects single-bit errors in flight, protecting data integrity on production workloads. The 288-pin RDIMM form factor fits only DDR5 RDIMM slots, not UDIMM or SODIMM sockets.

Questions about this item

What comes in the 384GB kit and do I need to buy anything else to install it?

The kit contains eight 48GB DDR5-5600 CL46 2Rx8 registered ECC RDIMMs at 1.1V. No additional parts are required; the modules plug directly into the Supermicro H13SSH-E motherboard's 288-pin DDR5 slots.

Should I choose this 8x48GB kit or a different capacity for my Supermicro H13SSH-E?

Select this 384GB kit when the board's memory-population rules allow eight 48GB 2Rx8 RDIMMs and you need the maximum supported capacity. Check the motherboard manual for approved DIMM configurations and population order before deciding.

What does the DDR5-5600 CL46 rating mean once the modules are running in the server?

The modules will operate at 5600 MT/s with a CAS latency of 46 cycles at 1.1V. Registered buffering and on-die ECC let all eight slots run fully populated at this rated speed while correcting single-bit errors in real time.
