Exact-match DDR5 server kit

This 384GB kit contains six 64GB DDR5 6400 CL52 RDIMMs built to the precise rank, voltage and timing the Supermicro H13SVW-NT memory controller expects. Registered ECC architecture with 2Rx4 organisation allows every slot to run fully populated at rated speed while correcting single-bit errors on the fly. It is not for buyers who need UDIMM or SODIMM form factors.

Thermals and power in normal use

Modules operate at 1.1V without heat spreaders, relying on server chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller, keeping power draw predictable across all six slots. No active cooling or additional voltage is required for standard operation.

Bundled kit contents and support

The package delivers the complete 6x64GB matched set so population order follows the motherboard manual without mixing modules. Lifetime replacement warranty and US-based technical support cover verification of fitment and troubleshooting after installation.

Questions about this item

How do I install the 6x64GB DDR5 RDIMM kit in my Supermicro H13SVW-NT, and which population rule is often missed?

Populate all six 288-pin slots following the motherboard manual's exact DIMM order; the step most often missed is using the prescribed sequence instead of filling slots sequentially.

What maintenance or replacement will the 384GB ECC RDIMM kit need over its service life?

No routine maintenance is required; the modules have no heat spreader and run at 1.10V, so only a failed DIMM would need replacement under the lifetime warranty.

What limit appears first when the 6400 CL52 2Rx4 kit runs sustained workloads?

The CAS latency of 52 cycles at DDR5-6400 sets the timing boundary that governs sustained throughput before any thermal throttle can occur.
