Four green DDR5 RDIMM modules without heat spreaders in a 512GB kit

NEMIX RAM

NEMIX RAM 512GB 4x128GB DDR5 6400 CL52 1.1V 2Rx4 RDIMM ECC memory upgrade

SKU CH-DV3H-XAMVB

512 GB server memory kit with four 128 GB DDR5 6400 CL52 1.1 V 2Rx4 registered ECC RDIMMs for the Supermicro H14DSG-O-CPU motherboard

  • Capacity512GB (4 x 128GB)
  • Type288-Pin DDR5 RDIMM
  • SpeedDDR5 6400 (PC5 51200)
  • CAS LatencyCL52
  • Voltage1.10V
  • ECCYes
  • 512 GB total capacity from four 128 GB modules for dense server workloads
  • DDR5 6400 speed with CL52 latency delivers rated bandwidth on compatible platforms
  • 10 V operation reduces power draw per module in fully populated systems
  • Registered ECC RDIMM design corrects single-bit errors and stabilises heavy memory loads
  • Verified fit for Supermicro H14DSG-O-CPU motherboard with 288-pin RDIMM slots

Exact-match capacity and speed

This kit delivers 512GB across four 128GB DDR5 6400 RDIMM modules at CL52 and 1.1V. It is built for the Supermicro H14DSG-O-CPU motherboard and other systems that require Registered ECC memory in this exact configuration. The 2Rx4 rank structure matches the controller expectations for full-capacity recognition.

Registered design and 288-pin fit

Registered buffering reduces electrical load on the memory controller so all four slots can run populated at rated speed. ECC corrects single-bit errors on the fly to prevent silent data corruption. The 288-pin RDIMM form factor installs only in compatible server DIMM slots; it will not fit UDIMM or SODIMM sockets.

Upgrade from smaller or slower kits

Replacing a lower-capacity or lower-speed RDIMM set with this kit adds the bandwidth and density needed for heavily threaded workloads. The jump is worthwhile when your current population leaves slots empty or forces a reduced frequency, and the board's qualified-vendor list includes this part number.

Otázky k tomuto produktu

What speed does the DDR5 6400 interface run at when all four 128GB RDIMMs are populated?

The kit is rated at DDR5 6400 (PC5-51200) with CL52 latency at 1.1V, and the registered architecture keeps every slot running at that speed when fully populated.

Will these 288-pin RDIMMs fit the Supermicro H14DSG-O-CPU motherboard's DIMM slots?

Yes, the 288-pin registered RDIMM form factor matches the board's required slot type and population rules exactly.

How do I install the 4x128GB kit correctly, and which step is most often missed?

Follow the motherboard manual's approved DIMM population order for all four slots; the step most often missed is verifying the exact slot sequence before inserting the modules.
