Exact-match server upgrade

This 64 GB DDR4 module runs at 3200 MT/s with CL22 timing and 1.2 V operation. It is built as a 2Rx4 registered ECC RDIMM for the Supermicro X12SPT-G and X12SPT-GC motherboards. The spec-matched design lets the memory controller recognise full capacity at rated speed without manual tuning.

Registered ECC architecture

The registered buffer reduces electrical load on the memory controller so every slot can stay populated at full density. On-die ECC detects and corrects single-bit errors in real time, preventing silent data corruption and unplanned reboots in production workloads. No heat spreader is included, relying on chassis airflow for thermal management.

288-pin RDIMM form factor

The 288-pin registered DIMM fits only boards wired for RDIMM signalling; it will not work in UDIMM or SODIMM slots. Builders must follow the motherboard manual for approved population order and maximum supported capacity per channel. Major-brand Samsung, Micron or Hynix DRAM chips are used, and the module carries a lifetime replacement guarantee with US-based technical support.

Questions about this item

Does the 64GB DDR4 3200 module require any periodic maintenance or component replacement after installation?

No, the DDR4 RDIMM has no moving parts or user-serviceable components and does not require scheduled maintenance or replacement under normal operation.

What is the first limit reached when the 2Rx4 registered ECC memory runs at full load for extended periods?

The DDR4 3200 modules operate at a fixed 1.2V with CL22 latency, so the electrical and timing limits defined by the JEDEC PC4-25600 standard are the boundaries encountered first.

How much heat and noise does the 288-pin ECC RDIMM produce when the server runs continuously?

The module has no heat spreader or fan, so it adds minimal heat and zero noise; all thermal load is handled by the server's existing airflow and cooling system.
