16 GB DDR5 4800 UDIMM

This 16 GB DDR5 4800 module is a JEDEC-standard unbuffered DIMM built for desktop, workstation, NAS and all-in-one systems. It runs at 1.1 V with CL40 latency and uses a 1Rx8 288-pin layout without a heat spreader.

Suitable for JEDEC DDR5 platforms

The stick fits any desktop or workstation that accepts 288-pin DDR5 UDIMMs at 4800 MT/s and 1.1 V. Systems requiring ECC, registered modules, lower voltage or a different pin count should use a different part.

1.1 V operating voltage

The 1.1 V requirement is the single specification that decides compatibility; the motherboard and CPU memory controller must support this exact voltage for the module to function.

Questions about this item

What DDR5 speed and CAS latency does this 16 GB module run at?

It operates at 4800 MT/s with a CL40 timing, matching the PC5-38400 JEDEC standard.

Does the 288-pin UDIMM fit a standard desktop DIMM slot without a heat spreader?

Yes, the bare 288-pin unbuffered DIMM uses the standard desktop form factor and has no heat spreader to clear tall CPU coolers.

What voltage must the motherboard supply for this 1.1 V DDR5 kit to work?

The module requires the standard DDR5 1.1 V; enable the JEDEC default profile in BIOS so the board does not apply a higher voltage.
