32GB DDR5 4800 Module

This 32GB DDR5 4800 UDIMM is built for the MSI Z790 Project Zero motherboard. It delivers 32GB of system memory in a single 288-pin stick rated at CL40 latency and 1.1V operation. The module uses major OEM chips from Samsung, Micron or Hynix and carries the MD38400-328K1 part number. It targets builders and upgraders who need a validated 32GB DDR5 kit for this specific platform.

Single Slot Unbuffered Design

The stick fits one standard 288-pin DDR5 DIMM slot and requires no registered or ECC support from the board. Its unbuffered 2Rx8 organisation leaves three additional slots free on a typical four-slot Z790 layout for future expansion. Installation follows the motherboard manual and needs no extra power cables, cooling headers or software configuration beyond standard BIOS memory training.

32GB Capacity At DDR5 4800

The 32GB density handles mainstream gaming, content creation and multitasking workloads with comfortable headroom. At the rated 4800 MT/s speed and CL40 timing the module runs within JEDEC baseline specifications for stable operation. It will not serve workloads that demand higher frequencies, lower latencies or capacities beyond 32GB per slot without additional modules.

Questions about this item

Will the CL40 latency and 1.1V voltage limit performance during sustained heavy workloads?

The module runs at DDR5 4800 with CL40 timing and 1.10V standard voltage. These are JEDEC base specifications. No heat spreader is fitted, so thermal throttling may occur under prolonged maximum load.

How much heat and noise does this module generate when running all day?

The UDIMM operates at 1.10V without a heat spreader. It produces minimal heat and zero noise since it has no moving parts. Case airflow is sufficient for typical daily operation.

What motherboard slot and chipset must I already have for this 288-pin DDR5 UDIMM to work?

You need a motherboard with a 288-pin DDR5 UDIMM slot and a chipset that supports DDR5 4800 non-ECC unbuffered memory, such as the MSI Z790 Project Zero referenced in the compatibility list.
