Speed 4800MHz

  • 64 GB capacity in a matched 2×32 GB kit for full server performance
  • DDR5-4800 speed with CL40 latency delivers rated bandwidth without tuning
  • ECC and registered design correct single-bit errors and stabilise fully populated slots
  • 1 V operation at 288-pin RDIMM form factor matches the motherboard's electrical spec
  • Validated for Supermicro H13SVW-NT so the kit is recognised at full capacity

Server-grade DDR5 64GB kit

This 64GB kit contains two 32GB DDR5 4800 Registered ECC RDIMMs built for the Supermicro H13SVW-NT motherboard. The 2Rx8 modules run at 1.10V with CL40 timing and match the exact rank, voltage and timing the board's memory controller expects. System integrators upgrading compatible Supermicro platforms receive a verified fit that populates every slot at rated speed. Buyers needing unbuffered UDIMMs or laptop SODIMMs cannot use these modules.

Sustained-load stability

Registered architecture buffers the command and address signals so the memory controller stays within its electrical limits even when all channels are fully populated. ECC circuitry detects and corrects single-bit errors on the fly, preventing silent data corruption during long compute runs. The 1.10V operating voltage keeps power draw predictable under continuous server workloads. Workloads that demand higher frequencies or lower latencies than DDR5 4800 CL40 will not be satisfied by this kit.

DDR5 4800 interface limits

The PC5-38400 standard caps transfer rate at 4800 MT/s, so bandwidth scales with channel count rather than per-module speed. Four 288-pin RDIMM slots on the target board set the physical ceiling for this kit's capacity. Mixing ranks or voltages beyond the board's qualified vendor list breaks the memory-training sequence at boot. Systems requiring speeds above 4800 MT/s or capacities beyond the motherboard's validated maximum must choose a different memory specification.

Questions sur cet article

How much power does the 1.1V DDR5 4800 kit draw when the server runs continuously?

Each module operates at 1.10V DDR5 standard voltage. Registered architecture reduces electrical load on the memory controller, helping keep system power draw predictable during all-day workloads.

What motherboard slot and population rules must my Supermicro H13SVW-NT already follow for this 2Rx8 RDIMM kit?

The board requires 288-pin DDR5 RDIMM slots. Install the pair in the sequence the manual specifies for 2Rx8 registered DIMMs so the memory controller recognises the full 64GB at rated speed.

Will the 288-pin DDR5 registered ECC modules work in the same chassis as older DDR5 RDIMMs I may keep?

Yes, if the remaining slots accept DDR5 288-pin RDIMMs. Match speed, voltage, rank and ECC type per the motherboard population rules; mixed ranks or voltages can prevent the full 64GB from being recognised.
