Targeted Server Upgrade

This 32GB DDR5 module is an ECC registered RDIMM built for specific Gigabyte workstation and server boards. It addresses administrators who need to add capacity to a H223-Z10, H233-Z80, H253-Z10, H273-Z80 or H273-Z81 system. The part is not compatible with standard desktop computers or with unbuffered and load-reduced memory types.

Build Integration

The stick plugs into a 288-pin DDR5 slot and runs at 1.1V with a CL40 timing at 4800 MT/s. Because it is registered, the memory controller sees a lighter electrical load, which helps stability when multiple modules are populated. It cannot be mixed with unbuffered or ECC load-reduced DIMMs, so the rest of the array must match this registered specification.

Compliance and Support

The module meets JEDEC and RoHS standards, making it a warranty-safe upgrade for the listed platforms. OWC backs the part with a limited lifetime warranty and an advanced replacement programme that includes free technical support. No heat spreader is fitted, so airflow in the chassis should be adequate for bare DRAM.

Questions about this item

Will the 4800 MT/s DDR5 speed hold under continuous server workloads?

The module runs at the JEDEC-standard 4800 MT/s with CL40 latency; sustained throughput depends on the host platform's memory controller and cooling.

How much heat does the 1.1 V registered DIMM produce during all-day operation?

At 1.1 V the module draws low power for DDR5, and with no heat spreader it relies on chassis airflow to stay within thermal limits.

Which Gigabyte motherboards must I already have for this 288-pin RDIMM to work?

Compatible systems are the Gigabyte H223-Z10, H233-Z80, H253-Z10, H273-Z80 and H273-Z81.
