  • Validated for Gigabyte G493 and G593 server platforms

Capacity and compatibility

This 64GB DDR5 ECC registered RDIMM is built for Gigabyte G493 and G593 server platforms. It targets administrators who need to add or replace memory in those specific workstation and server chassis.

Upgrade path

It replaces lower-capacity registered ECC modules in the same slots and cannot be mixed with unbuffered or load-reduced DIMMs. The jump is worth it when the workload demands more than the current memory ceiling allows.

Installation notes

The 288-pin module seats like any standard RDIMM and runs at 1.1V without extra configuration. Errors usually come from mixing registered with unbuffered memory or populating slots the board does not support.

Questions about this item

Does the 288-pin DDR5 RDIMM fit the Gigabyte G493-ZB2 server motherboard?

Yes, the module is a 288-pin DDR5 ECC Registered DIMM validated for Gigabyte G493-ZB2, G493-ZB3, G593-ZD1, G593-ZD2 and G593-ZX1 systems.

What is the correct installation sequence for this 2Rx4 registered module?

Power down, open the chassis, align the notch on the 288-pin edge connector with the slot key, press firmly until both retention clips click, then power on and verify 4800 MT/s operation in BIOS.

When should the 64 GB ECC RDIMM be replaced?

Replace if the system logs uncorrectable ECC errors, fails memory diagnostics, or no longer posts at the rated 4800 MT/s CL40 1.1 V settings.
