Single 64GB DDR4 ECC RDIMM

This OWC module provides 64GB of DDR4 3200 memory in a single 288-pin registered DIMM. It is built for Gigabyte E252-P30, E252-P31, G242-P31, G242-P32 and G242-P33 servers and workstations that require ECC registered RAM. Standard desktop computers cannot use this module.

1.2V operation with JEDEC timing

The module runs at 1.2V with a CAS latency of 22 and conforms to the PC4-25600 JEDEC standard. No heat spreader is fitted, so airflow in the server chassis handles cooling. Registered buffering adds a clock cycle but reduces electrical load on the memory controller.

No mixing with unbuffered or load-reduced DIMMs

The 2Rx4 registered design means this DIMM must not be combined with unbuffered or ECC load-reduced memory in the same system. It is backward compatible with 2133, 2400, 2666 and 2933MHz bus speeds, allowing use in older Gigabyte platforms that support those rates.

Questions about this item

How do I install this 288-pin ECC RDIMM in a Gigabyte E252-P30, and what step is often missed?

Power down, open the chassis, align the notch on the 288-pin module with the slot key, press firmly until both latches click, then verify in BIOS that ECC registered mode is active — skipping the BIOS check is the common miss.

What maintenance or replacement will this 64GB DDR4 3200 CL22 module need over time?

No scheduled maintenance is required; the module has no heat spreader and runs at 1.2V, so only replace it if a memory test reports correctable ECC errors rising or a DIMM fails POST.

What limit appears first when this 2Rx4 registered DIMM runs sustained workloads?

The registered buffer adds one clock cycle of latency, so sustained throughput tops out at the JEDEC 3200 MT/s rating; thermal throttling is unlikely at 1.2V without a spreader.
