  • 512 GB total capacity from four 128 GB modules for dense server workloads
  • DDR5 4800 speed with CL40 latency delivers rated bandwidth without tuning
  • Registered ECC architecture corrects single-bit errors and stabilises fully populated slots
  • 1 V operation matches the Supermicro H13DSG-O-CPU memory controller specification
  • 288-pin RDIMM form factor fits the exact motherboard slot and population rules

Exact-match 512 GB kit for Supermicro H13DSG-O-CPU

This 512 GB kit contains four 128 GB DDR5 registered ECC RDIMMs that run at 4800 MHz with CL40 timing and 1.1 V. The 2Rx4 organisation and 288-pin form factor match the motherboard’s memory-controller expectations so the full capacity is recognised at rated speed.

Suited for fully populated server builds

Administrators expanding a Supermicro H13DSG-O-CPU system to its maximum supported DIMM count will benefit from the registered architecture that keeps every slot stable. Buyers who need unbuffered UDIMMs, SODIMMs, or a smaller total capacity should look elsewhere.

Steady throughput under continuous load

Registered buffering offloads the memory controller, allowing all four modules to sustain full-speed operation during long compute jobs. ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots during extended production runs.

Questions sur cet article

Does the Supermicro H13DSG-O-CPU motherboard need a specific BIOS revision to recognise the 512 GB kit at DDR5-4800?

The kit is validated for that motherboard; consult the board manual for the minimum BIOS version that enables full 512 GB capacity at the rated 4800 MT/s speed.

Can I mix these 128 GB 2Rx4 RDIMMs with smaller DDR5 RDIMMs already installed in the same server?

Mixing different capacities or ranks is not recommended; the board's population rules require identical modules per channel to maintain stability and ECC integrity.

How do I confirm the system is using all 512 GB at CL40 1.10 V after installation?

Enter the BIOS or use a tool such as dmidecode to verify each slot shows 128 GB, 4800 MT/s, CL40 timing and 1.10 V operating voltage.
