SuperMicro DDR5 4800 192GB Kit

This 192GB kit contains four 48GB DDR5 4800 UDIMM modules built for SuperMicro desktop workstations. It targets professionals who need high-capacity memory for memory-intensive applications on compatible platforms. The modules operate at 1.1V with CL40 latency and use a 2Rx8 organization without ECC or heat spreaders.

Sustained Load Stability

All modules are rigorously stress tested under load to ensure reliability during extended workloads. The 1.1V operating voltage helps maintain consistent thermal behaviour across the four DIMMs when the system runs at full capacity for long periods. Unbuffered topology keeps the signal path direct for predictable timing under continuous pressure.

DDR5 UDIMM Platform Limits

The 288-pin DDR5 UDIMM standard defines the electrical and mechanical interface used by this kit. Maximum capacity and speed depend on the motherboard memory controller and qualified vendor list rather than the modules alone. Builders must verify that their specific SuperMicro board supports 48GB density per slot at 4800 MT/s before installation.

Questions about this item

How much power does the 1.10V DDR5 4800 kit draw under sustained load?

Each 48GB module runs at 1.10V, so the four-module 192GB kit stays at the standard DDR5 1.10V operating voltage during continuous use.

Which motherboard slots and chipset are required for the 288-pin UDIMM kit to function?

The kit needs a motherboard with four 288-pin DDR5 UDIMM slots and a chipset that supports DDR5 4800 non-ECC unbuffered memory, such as the Supermicro C9Z790-CGW board.

Will the CL40 2Rx8 modules run stably alongside any existing DDR5 4800 sticks I keep?

Mixing is reliable only when the retained sticks are also DDR5 4800 CL40 2Rx8 1.10V non-ECC unbuffered UDIMMs; otherwise the system will default to the slowest common timing.
