Server-Specific ECC Registered Memory

This 32GB DDR4 3200 module is an ECC Registered RDIMM built for the Gigabyte MZ72-HB2 and R152-P30 through R152-P33 platforms. It operates at 1.2V with CL22 latency and a 2Rx4 rank configuration. The module is designed for workstation and server environments that require registered memory with error correction.

Registered DIMM Platform Constraints

This memory uses the 288-pin DDR4 RDIMM form factor and will not fit or function in standard desktop computers that require unbuffered UDIMMs. It cannot be mixed with unbuffered or load-reduced ECC modules in the same system. The registered buffer adds a clock cycle, so the platform chipset and BIOS must explicitly support registered DIMMs.

Verify Registered DIMM Support Before Ordering

Check your system documentation to confirm it accepts DDR4 ECC Registered RDIMMs and cannot use unbuffered or LRDIMM types. Ensure the motherboard has free 288-pin DDR4 slots and that the BIOS is updated for registered memory compatibility. This module is backward compatible with 2133, 2400, 2666 and 2933MHz bus speeds.

Questions about this item

Should I pick the single 32 GB module or a different capacity for my Gigabyte MZ72-HB2?

This listing is a single 32 GB DDR4 3200 ECC registered RDIMM. Add more identical modules to reach the total memory your server board supports.

What does the 3200 MT/s rating deliver once the module is installed in a Gigabyte R152-P30?

The module runs at DDR4 3200 CL22 at 1.2 V. If the system bus is slower it will down-clock to 2933, 2666, 2400 or 2133 MT/s automatically.

How does the 288-pin ECC registered RDIMM interface affect what I can install alongside it?

The 288-pin registered DIMM slot only accepts DDR4 ECC registered modules. It cannot be mixed with unbuffered or load-reduced memory.
