Show 12 more configurations
  • 512 GB total capacity with four 128 GB modules for maximum density
  • DDR5 4800 speed rated at PC5-38400 for high throughput
  • Registered ECC design corrects single-bit errors and stabilises fully populated slots
  • CL40 latency at 1.1 V matches the motherboard's memory controller expectations
  • 288-pin RDIMM form factor fits the Supermicro H13SVW-NT-OS2 board exactly

Exact-match DDR5 upgrade kit

This 512GB kit contains four 128GB DDR5 4800 RDIMMs built to the precise rank, voltage and timing the Supermicro H13SVW-NT-OS2 motherboard expects. Registered ECC architecture offloads the memory controller and corrects single-bit errors so fully populated slots run at rated speed without silent data corruption. It is for administrators who need maximum capacity on this specific platform.

Replaces partial or mismatched memory

The kit upgrades from smaller-capacity RDIMMs, mixed-rank sets or non-ECC modules that force the board to down-clock or disable slots. The jump is worth it when the workload demands the full 512GB at DDR5 4800 with CL40 latency and 1.1V operation. It is not for systems that only accept UDIMMs, SODIMMs or lower-density registered DIMMs.

Slot-in RDIMM installation

Install by following the motherboard manual's population order for four 2Rx4 registered modules; the 288-pin form factor seats like any standard DDR5 RDIMM. What usually goes wrong is ignoring the approved slot sequence or mixing ranks, which prevents the system from recognizing the full capacity. Verify the manual before starting.

Questions about this item

Does the 288-pin RDIMM form factor fit the Supermicro H13SVW-NT-OS2 motherboard slots?

Yes, the 288-pin Registered DIMM form factor matches the slots on the Supermicro H13SVW-NT-OS2 motherboard; UDIMM or SODIMM modules will not fit.

What population order does the manual require for the four 128GB 2Rx4 modules?

Install the four 2Rx4 modules in the exact slot sequence shown in the Supermicro H13SVW-NT-OS2 manual; wrong order can prevent the system from recognising the full 512GB capacity.

When should I reseat or replace a module if ECC logs show corrected errors?

Reseat the 288-pin RDIMM if corrected-error counts rise on a specific slot; replace the module if errors persist after reseating and firmware updates.
