NEMIX RAM 256GB DDR4 3200MHz PC4-25600 8Rx4 CL22 288-Pin ECC Registered RDIMM memory upgrade

SKU CH-JSBD-Q4H3S

256GB DDR4 3200MHz registered ECC RDIMM kit with 8Rx4 ranks, CL22 latency, 1.2V operation, and 288-pin form factor validated for Supermicro X12DPL-NT6 and X12DPL-i6 motherboards

  • Capacity256GB
  • Type288-Pin DDR4 RDIMM
  • SpeedDDR4 3200 (PC4 25600)
  • CAS LatencyCL22
  • Voltage1.20V
  • ECCYes

Size 256GB

  • 256GB total capacity fills every slot on supported Supermicro X12DPL boards
  • Registered ECC design offloads the memory controller and corrects single-bit errors automatically
  • DDR4-3200 PC4-25600 speed matches the motherboard's rated frequency for full-throughput operation
  • 2V CL22 8Rx4 timings meet the exact electrical spec the platform expects
  • 288-pin RDIMM form factor fits only the registered DIMM slots these boards require

Exact-match server memory

This 256GB DDR4 3200MHz kit is built for the Supermicro X12DPL-NT6 and X12DPL-i6 motherboards. It delivers 8Rx4 registered ECC RDIMMs at 1.2V with CL22 timing so the controller recognises full capacity at rated speed. The 288-pin form factor matches the board's population rules precisely. Buyers who need a different motherboard or a smaller capacity kit should look elsewhere.

Sustained enterprise stability

Registered architecture offloads the memory controller so every slot runs fully populated at full capacity under continuous load. ECC corrects single-bit errors on the fly preventing silent data corruption and unplanned reboots during production workloads. The 1.2V operation keeps power draw consistent across all modules. This is not suited for desktop boards that require unbuffered UDIMMs.

Straightforward slot installation

Modules seat in standard 288-pin DDR4 RDIMM slots following the motherboard's documented population order. No heat spreader means clearance is rarely an issue in dense server chassis. The most common error is mixing registered and unbuffered DIMMs or ignoring the manual's slot sequence which prevents the system from posting at full capacity. Always verify the configuration guide before installing.

Questions about this item

How much power does the 1.2 V DDR4 kit draw when the server runs continuously?

Each module operates at 1.2 V, the standard DDR4 voltage, so total draw scales with the number of populated slots and the CPU memory controller load rather than the kit itself.

Which motherboard slots and chipset must I already have to install this 288-pin RDIMM?

You need a Supermicro X12DPL-NT6 or X12DPL-i6 board with DDR4 RDIMM slots that support 8Rx4 registered ECC modules and the correct population order listed in the manual.

Will this 256 GB 8Rx4 kit work alongside lower-rank DDR4 modules I keep from an earlier upgrade?

Mixing 8Rx4 registered ECC DIMMs with different-rank modules is not supported on the validated Supermicro platforms; the memory controller requires identical rank and ECC configuration per channel.
