Speed 4800MHz

  • 256 GB total capacity from four 64 GB modules for maximum density
  • DDR5 4800 MHz speed with CL40 latency delivers rated throughput
  • Registered ECC design corrects single-bit errors and stabilises full population
  • 10 V operation matches the motherboard's voltage requirement exactly
  • 288-pin RDIMM form factor fits the Supermicro H13SVW-N memory slots precisely

Exact-match server upgrade

This 256GB kit delivers four 64GB DDR5 4800MHz registered ECC RDIMMs built to the precise rank, voltage and timing the Supermicro H13SVW-N motherboard expects. It is for administrators who need the full 256GB capacity recognised at rated speed without manual tuning. Buyers who want unbuffered UDIMMs or SODIMM form factors cannot use this kit.

DDR5 4800 interface limits

The modules run at 1.1V with CL40 latency on the 288-pin DDR5 registered interface, so the memory controller sees a consistent electrical load across all populated slots. Registered buffering lets every slot run fully populated at the rated 4800MT/s, while on-die ECC corrects single-bit errors before they reach the OS. Systems that require a different voltage, latency or unbuffered topology will not post with these DIMMs.

Four-slot installation

Each 2Rx4 module seats in a standard 288-pin DDR5 RDIMM slot; the kit contains exactly four sticks for a complete population. The motherboard manual dictates the required slot order and any BIOS settings for full-capacity operation. Skipping the manual's population sequence is the most common reason the system reports less than 256GB or fails to boot.

Questions about this item

Should I pick the 256 GB kit or a smaller capacity for the Supermicro H13SVW-N?

The 256 GB kit fills four slots with 64 GB modules. Choose it only if your motherboard manual confirms support for that total capacity and the required population order.

Will the DDR5-4800 speed run at 4800 MHz once installed?

Yes, the modules are rated for DDR5-4800 (PC5-38400) and the board's memory controller will recognise the exact rank, voltage and timing to operate at that speed.

Does the 288-pin RDIMM interface limit how many modules I can install?

The 288-pin Registered RDIMM form factor is what the H13SVW-N requires. Population limits are defined by the motherboard manual, not by the module interface itself.
