Exact-Match Server Upgrade

This 64 GB DDR4 3200 Registered ECC RDIMM is built for the Supermicro X12QCH+ motherboard. The 2Rx4 organisation, 1.2 V operation and CL22 timing match the controller's requirements so the module is recognised at full capacity and runs at its rated PC4-25600 speed without manual tuning.

Thermals Power And Noise

Registered buffering reduces electrical load on the memory controller, keeping power draw steady at the specified 1.2 V even with every slot populated. The modules carry no heat spreader, relying on standard server airflow to maintain stable temperatures during continuous operation. Silent solid-state design adds no audible noise to the chassis.

When The Jump Is Worth It

This kit replaces lower-capacity or non-ECC UDIMMs that cannot be recognised in registered-only slots or that leave the system vulnerable to silent data corruption. The upgrade is justified when workloads demand maximum registered DIMM population, error correction and full 3200 MT/s throughput. Buyers needing unbuffered consumer memory or speeds beyond DDR4-3200 should look elsewhere.

Questions about this item

How do I install this 288-pin RDIMM on the Supermicro X12QCH+ and which slot order does the manual require?

Power down the server, open the chassis, and insert the module into the DIMM slots in the exact population sequence listed in the Supermicro X12QCH+ manual — typically filling the first slot of each channel before adding a second. The 288-pin keying only fits one way; press straight down until both ejector clips click.

Will the ECC function or the registered buffer need any firmware updates or periodic replacement?

No. ECC error correction and the registered buffer are hardware features of the DRAM and the register chip; they operate automatically and do not require firmware updates or scheduled replacement.

At what point does the CL22 latency become the bottleneck during sustained 3200 MT/s workloads?

CL22 is the rated CAS latency at 3200 MT/s; the memory controller issues reads at that timing continuously, so the latency ceiling is reached whenever the workload saturates the memory bus with random accesses.
