128 GB DDR5 ECC RDIMM for Gigabyte servers

This 128 GB DDR5 4800 CL40 4Rx4 ECC Registered RDIMM is built for Gigabyte G493 and G593 server platforms. It targets administrators who need single-module density in workstation, NAS, server or network-switch chassis.

Registered 4Rx4 layout at 1.1 V

The module uses a registered 4Rx4 organisation running at 1.1 V with CAS latency 40. That combination of rank structure and ECC registration is the single spec that determines whether the part will post in the qualified Gigabyte systems.

Keyed 288-pin installation with no heat spreader

The bare 288-pin DIMM seats like any RDIMM; align the notch, press until the latches click. Common issues are mixing registered modules with unbuffered or load-reduced DIMMs, or populating slots the platform does not validate for 4Rx4 density.

Perguntas sobre este artigo

How does the 4800 MT/s speed translate to actual throughput in a Gigabyte G493 or G593 server?

The module runs at DDR5-4800, delivering up to 38400 MB/s of peak bandwidth per DIMM when the platform operates at its rated data rate.

What does the PC5-38400 designation cap in practice?

PC5-38400 confirms a maximum transfer rate of 38400 MB/s under JEDEC standard timings; the server memory controller cannot exceed this limit with this DIMM.

Will the 288-pin registered DIMM fit the memory slots in a Gigabyte G493-ZB2?

Yes, the 288-pin ECC registered form factor matches the DDR5 RDIMM slots on the listed Gigabyte G493 and G593 models.
