8GB DDR5 4800 Desktop Module
This OWC module provides 8GB of DDR5 memory at 4800 MT/s with CL40 latency and 1.1V operation. It uses a 288-pin unbuffered non-ECC UDIMM form factor. The part is built to JEDEC and RoHS standards as a direct replacement for Micron MTC4C10163S1UC48B. It suits desktop, workstation, NAS and all-in-one systems needing a standard capacity upgrade.
Sustained load behaviour
DDR5 architecture moves data at 4800 MT/s with a single 1Rx16 rank per module. The CL40 timing and 1.1V voltage are JEDEC baseline values, so throughput remains steady during long sessions without relying on overclock headroom. No heat spreader is fitted, so case airflow determines thermal performance under continuous use.
Installation notes
The 288-pin UDIMM slots into any desktop DDR5 socket keyed for unbuffered non-ECC memory. Alignment notch and side clips are the only mechanical steps; no drivers or BIOS toggles are required for JEDEC operation. The most common error is mixing this module with different speeds, ranks or voltages, which forces the system to downclock or fail to POST.

Questions about this item
How much power does the 8 GB DDR5 4800 CL40 module draw when the system runs all day?
The stick operates at the JEDEC-standard 1.1 V, keeping power draw low during continuous desktop workloads.
What must the motherboard provide for this OWC 8 GB DDR5 4800 CL40 stick to work?
A desktop board with a 288-pin unbuffered DDR5 DIMM slot is required; the module is non-ECC and unbuffered.
Will this DDR5 4800 CL40 module run stably alongside older memory already installed?
The module follows JEDEC DDR5 4800 specifications, so the memory controller will set a common speed and timing for all populated slots.
