32GB DDR5 ECC RDIMM for Gigabyte servers

This 32GB DDR5 4800 CL40 2Rx8 registered DIMM is built for Gigabyte G293-Z42, G293-Z43, G363-ZR0, G493-ZB0 and G493-ZB1 systems. It targets administrators upgrading workstation or server memory where ECC registered modules are required. Standard desktop platforms cannot use this module.

Thermals noise and power draw

Operating at 1.1V JEDEC standard voltage, the module draws minimal power per stick and runs without a heat spreader. Registered buffering reduces electrical load on the memory controller, helping keep system thermals stable under sustained server workloads. Fan noise remains governed by the chassis, not the memory itself.

JEDEC compliance and warranty-safe upgrade

Full JEDEC and RoHS compliance guarantees a warranty-safe installation that meets OEM specifications. The single 32GB stick allows precise capacity scaling across the supported Gigabyte platforms without mixing registered and unbuffered or load-reduced DIMMs. OWC testing validates reliability for production deployments.

Questions about this item

How do I install this 288-pin DDR5 ECC RDIMM in a Gigabyte G293-Z42, and what step is often missed?

Power down the server, open the chassis, align the 288-pin module with the DDR5 slot key notch, press firmly until the retention clips click, then enable ECC in BIOS — the step most often missed is confirming the BIOS recognises the registered DIMM and activates ECC.

What maintenance or replacement will this 32 GB 2Rx8 module need over its service life?

No routine maintenance is required; the module has no heat spreader or moving parts. Replacement is only needed if a memory error count exceeds the platform threshold or if a capacity upgrade demands higher-density DIMMs.

What limit appears first when this 4800 CL40 1.1 V registered DIMM runs sustained workloads in a G493-ZB0?

The registered buffer and CL40 latency set the effective throughput ceiling; sustained bandwidth will plateau at the JEDEC DDR5-4800 rate before thermal or voltage limits are reached.
