32GB DDR4 DIMM for System Upgrades

This 32GB DDR4 module runs at 2666MHz with a CAS latency of 19 and operates at 1.2V. It is an unbuffered, non-ECC DIMM built with a 2Rx8 rank configuration using major brand chipsets. The 288-pin design fits standard desktop memory slots.

Single-Module Configuration and Lifetime Warranty

Supplied as a single 32GB stick, the kit lets you add capacity to an existing channel or start a new build with one module. A limited lifetime warranty against manufacturing defects covers the part when purchased from Computer Memory Solutions. Product appearance may vary from the reference image shown.

DDR4 2666MHz Speed Rating

The module is rated for DDR4 2666 (PC4 21300) operation; all installed memory will run at the speed of the slowest module or the processor's memory controller limit. A 64-bit operating system is required to address more than 4GB of total system memory.

Questions about this item

Will the 2Rx8 rank configuration on this 32GB DDR4 module need any special BIOS setting later?

The module uses a standard 2Rx8 organisation that the memory controller handles automatically; no manual rank configuration is required.

What limits sustained throughput on this CL19 2666MHz kit when running all day?

The CAS 19 timing at 2666 MHz sets the latency floor, so sustained bandwidth is capped by that speed grade rather than thermals.

How much extra heat or power does the 1.2V unbuffered DIMM add during continuous operation?

At the rated 1.2 V the module draws only its standard DDR4 power envelope, producing minimal additional heat inside the chassis.
