Server Memory Upgrade

This 64 GB DDR4 3200 ECC RDIMM is built for Supermicro servers and workstations that require registered memory with error correction. The single 64 GB module uses a 2Rx4 organisation and runs at 1.20 V with CL22 latency, adding high-density capacity to compatible platforms.

Thermals and Power

Operating at the standard DDR4 voltage of 1.20 V keeps power draw low and heat output minimal in normal server workloads. Without a heat spreader the module relies on chassis airflow, so adequate case ventilation is the only thermal requirement.

Build Integration

The 288-pin RDIMM fits Supermicro motherboards that support registered ECC DDR4; it does not work in unbuffered consumer boards. One module occupies a single DIMM slot, leaving remaining slots free for further capacity expansion.

Questions about this item

How do I install this 288-pin DDR4 RDIMM in a Supermicro server, and what step is often missed?

Align the notch with the slot key, press firmly until both retention clips click, then verify in BIOS that the module registers at 3200 MT/s and ECC is active — skipping the BIOS check is the common oversight.

What maintenance or replacement will this 64 GB ECC RDIMM need over its service life?

No scheduled maintenance is required; the module has no heat spreader or moving parts, and ECC corrects single-bit errors transparently — replacement only occurs if a multi-bit error exceeds correction capability.

What limit appears first when this CL22 1.2 V module runs sustained workloads?

The CAS latency of 22 cycles at 3200 MT/s sets the timing floor; under continuous load the memory controller will hit this latency ceiling before voltage or thermal constraints become binding.
