Six green DDR5 RDIMM sticks in a row, no heat spreaders

NEMIX RAM

NEMIX RAM 384GB 6x64GB DDR5 6400 CL52 2Rx4 ECC Registered RDIMM memory upgrade

SKU CH-5BWQ-PM2N0

Six 64 GB DDR5 registered ECC RDIMMs running at 6400 MT/s CL52 and 1.1 V, validated for the Supermicro H13SSW motherboard

  • Total capacity384 GB (6 × 64 GB)
  • Rated speedDDR5 6400 (PC5 51200)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • 384 GB total capacity across six matched 64 GB modules
  • DDR5 6400 speed with CL52 latency for rated server performance
  • Registered ECC design offloads the controller and corrects single-bit errors
  • 1 V operation at 2Rx4 rank matches the board's memory controller requirements
  • Validated for the Supermicro H13SSW motherboard with 288-pin RDIMM form factor

Exact-Match Server Upgrade

This 384GB kit delivers six 64GB DDR5 6400 RDIMMs tuned to CL52 at 1.10V. It targets administrators upgrading a Supermicro H13SSW platform that requires registered ECC modules in a 2Rx4 configuration.

Replaces Mismatched Or Partial Kits

The jump is worth it when a server currently runs mixed capacities, slower speeds, or unbuffered DIMMs that prevent full-slot population. Matching rank, voltage, and timing lets the memory controller recognise every module at rated throughput without down-clocking.

Straightforward Slot Installation

Align the 288-pin notch, press firmly until the latches click, and follow the board's prescribed population order. The most common issue is skipping the manual's slot sequence, which can leave capacity unseen or force reduced speeds.

Questions about this item

Will these 288-pin DDR5 RDIMMs fit the Supermicro H13SSW motherboard slots?

Yes, the kit uses the 288-pin Registered DDR5 form factor that the H13SSW requires, and the 2Rx4 rank matches the board's population rules.

What is the correct installation order for the six 64 GB modules on the H13SSW?

Follow the motherboard manual's DIMM population sequence; install modules in the prescribed slot order so the memory controller recognises all 384 GB at DDR5-6400.

When should the RDIMMs be replaced to maintain ECC protection?

Replace any module that logs correctable ECC errors persistently or fails memory diagnostics, as continued use risks uncorrectable errors and unplanned downtime.
