Server-grade DDR4 ECC RDIMM

This 32GB OWC module delivers DDR4 3200 performance with ECC registered operation for workstations and servers. The 288-pin RDIMM form factor fits compatible server motherboards that require registered memory. It is not compatible with standard desktop computers or unbuffered memory configurations.

JEDEC-compliant registered design

Built to JEDEC-standard specifications at 1.2V with CL22 latency and 2Rx4 organisation. The registered buffer reduces electrical load on the memory controller for stable operation in multi-DIMM server environments. No heat spreader is included, allowing dense side-by-side population in qualified chassis.

Direct replacement for Supermicro parts

Matches the exact specifications of Supermicro MEM-DR432L-HL01-ER32, MEM-DR432L-HL02-ER32 and MEM-DR432L-SL02-ER32 modules. This compatibility simplifies procurement when maintaining or expanding existing Supermicro infrastructure. OWC tests every module in-house to meet or exceed OEM requirements.

Questions sur cet article

What speed does the DDR4 3200 PC4-25600 interface actually run at?

The module operates at DDR4 3200 MT/s, which is the PC4-25600 data rate; the system memory controller sets the final speed based on CPU support and DIMM population rules.

What physical slot and clearance does this 288-pin RDIMM require?

It fits a standard DDR4 288-pin RDIMM socket; the module has no heat spreader, so it sits at the nominal JEDEC height for 1U and 2U server chassis.

How is this ECC Registered DIMM installed, and what step is often missed?

Power off the server, open the chassis, align the notch with the keyed slot, press firmly until both ejector tabs click; then enter BIOS to confirm ECC and registered mode are active.
