Supermicro H13SVW-NT-OS2 memory kit

This 768 GB kit contains six 128 GB DDR5 RDIMMs built for the Supermicro H13SVW-NT-OS2 motherboard. It targets administrators who need the full registered ECC capacity their server platform supports.

Registered ECC with 2Rx4 organisation

Registered buffering offloads the memory controller so every slot runs fully populated at rated speed. ECC corrects single-bit errors on the fly, preventing silent data corruption in production workloads.

288-pin DDR5 RDIMM installation

Modules seat in the board's 288-pin DDR5 slots following the manual's population order. Mismatched ranks, voltages or mixing UDIMMs will prevent the system from posting at full capacity.

Questions about this item

Will the 128 GB DDR5 RDIMMs need replacement due to wear over time?

No — solid-state DRAM has no moving parts and no write-cycle limit, so the modules do not wear out under normal server operation.

What limits sustained throughput on this 4800 MT/s CL40 kit?

The DDR5-4800 JEDEC data rate and CL40 latency set the maximum bandwidth and response time the memory controller can sustain.

How much heat and power do the six 1.1 V modules produce when the server runs all day?

Each module operates at 1.1 V with no heat spreader; total power draw and thermal output scale with the 768 GB capacity and DDR5-4800 activity level.
