16GB DDR5-4800 Desktop Memory Module

This 16GB DDR5-4800 DIMM is built as a direct replacement for the Corsair CM5S16GM4800A40T2 kit. It targets desktop owners who need a single 288-pin module to restore or expand system memory without changing platform.

Major-brand DRAM ICs tested at 4800 MT/s

The module uses major-brand DRAM ICs validated at 4800 MT/s and CL40 timings. Each stick ships unbuffered, non-ECC, and at the standard 1.10 V DDR5 voltage, so it drops into compatible boards without extra configuration.

1.10 V DDR5 standard voltage

Operation at 1.10 V confirms the module follows the baseline DDR5 specification, making voltage compatibility the single check that decides whether this part fits the target system.

Questions about this item

Will the 1.10V DDR5 module need any firmware or BIOS updates to stay stable over time?

The module runs at the standard 1.10V DDR5 voltage with a tested frequency of 4800 and CL40, so no extra firmware steps are required beyond normal motherboard BIOS updates.

What thermal limit appears first when the 16GB stick runs at 4800 continuously?

Without a heat spreader the DRAM temperature will reach its throttling point before the 1.10V power envelope becomes a concern.

How much power does the 288-pin DIMM draw during all-day operation?

At 1.10V the module stays within the standard DDR5 power envelope, producing minimal heat and no audible noise.
