Sixteen green DDR5 RDIMM modules in a row

NEMIX RAM

NEMIX RAM DDR5 ECC RDIMM 256GB 16x16GB 6400 CL52 1.1V 288-pin Registered Kit for Supermicro H13DSG-OM

SKU CH-YZ3C-3B1TF

256 GB DDR5 registered ECC kit in sixteen 16 GB modules at 6400 MT/s CL52 1.1 V for Supermicro H13DSG-OM

  • Total capacity256 GB (16 × 16 GB)
  • Rated speedDDR5 6400 (PC5 51200)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • 256 GB capacity in a 16-module kit fills every slot for maximum throughput
  • DDR5 6400 speed with CL52 latency delivers rated performance without tuning
  • 1 V registered ECC design offloads the controller and corrects single-bit errors
  • 288-pin RDIMM form factor matches the Supermicro H13DSG-OM memory population rules
  • Major OEM Samsung, Micron or Hynix chips provide enterprise-grade reliability

Capacity and Fit

This 256GB kit contains 16 registered DDR5 RDIMM modules, each 16GB, built for the Supermicro H13DSG-OM motherboard. The 288-pin form factor matches the board's DIMM slots exactly, so the memory controller recognises the full population at rated speed.

Registered ECC Limits

Registered architecture buffers the command bus, allowing every slot to run fully populated without overloading the memory controller. ECC corrects single-bit errors on the fly, but the modules operate only at the DDR5 6400 CL52 1.1V specification; they will not negotiate higher speeds or lower latencies.

Pre-Purchase Checks

Verify that your H13DSG-OM revision supports 16 modules of 1Rx8 density and confirm the required population order in the system manual. Ensure the BIOS version listed for this capacity is installed, because unsupported firmware will prevent the kit from training at 6400 MT/s.

Questions about this item

Should I choose the 16x16GB kit or a different capacity for my Supermicro H13DSG-OM?

The 256GB kit provides 16 modules of 16GB each, filling all slots on the H13DSG-OM for maximum registered ECC capacity at DDR5 6400 CL52.

What does the 6400 MT/s rating deliver once installed in the server?

The modules run at DDR5 6400 (PC5-51200) with CL52 latency and 1.10V, giving the memory controller the exact speed and timing it expects for full-rated throughput.

How does the 288-pin RDIMM interface affect performance limits on this board?

The registered 288-pin DDR5 RDIMM format buffers address and command signals, allowing all 16 slots to operate at 6400 MT/s without signal-integrity loss.
