Speed 4800MHz

  • 256 GB total capacity from a 2 x 128 GB kit
  • DDR5-4800 speed rated at PC5-38400 for high throughput
  • Registered ECC with 2Rx4 architecture for enterprise stability
  • CL40 latency at 1.1 V for efficient operation
  • Validated for Supermicro H13SVW-NT motherboard compatibility

Exact-match upgrade for Supermicro H13SVW-NT

This 256GB kit delivers two 128GB DDR5 4800MHz ECC Registered RDIMMs built to the board's precise rank, voltage and timing requirements. It targets administrators who need full-capacity population on a Supermicro H13SVW-NT server without compatibility guesswork.

Installation follows standard RDIMM procedure

Align the 288-pin modules with the motherboard slots and press until the latches engage; the registered architecture offloads the memory controller so every slot runs fully populated at rated speed. The main risk is ignoring the board's population order — consult the Supermicro manual for the approved sequence before installing.

Handles 256GB at DDR5 4800 CL40 1.1V

The kit provides 256GB of ECC-protected capacity with single-bit error correction that prevents silent data corruption in production workloads. It runs out when the application demands more than 256GB or requires speeds beyond the 4800MHz rating this module is specified for.

Questions about this item

How can I verify the DDR5 4800MHz kit is running at its rated 1.10V and CL40 after installation?

Enter the server BIOS or use a hardware monitoring tool to confirm each 128GB module shows DDR5-4800 speed, 1.10V voltage, and CL40 latency with ECC active.

What comes in the box and is any extra hardware needed for the Supermicro H13SVW-NT?

The package contains two 128GB 288-pin DDR5 RDIMM modules; no additional parts are required for the compatible motherboard.

Should I choose a different capacity or rank for the H13SVW-NT if I want full 256GB in two slots?

This 2Rx4 256GB kit matches the board's population rules for two-slot maximum capacity; other ranks or capacities would not provide the same 256GB total.
