8GB DDR4 2666 desktop module

This 8GB DDR4 2666 module uses the standard 288-pin desktop form factor and runs at 1.20V. It is unbuffered and non-ECC with a CAS latency of 19. The module supports the Intel XMP 2.0 profile for automatic configuration. It suits office PCs and basic home builds that need a single stick of memory.

Upgrade from 4GB or slower DDR4

Replacing a 4GB stick or a slower DDR4 module adds headroom for multitasking and avoids swapping to disk. The jump is worth it when the motherboard has a free 288-pin slot and the BIOS can apply the XMP 2.0 profile at 2666 MT/s. Systems already running 8GB or faster memory will not see a noticeable change.

Comfortable for everyday workloads

Eight gigabytes handles web browsing, document editing and light media playback without pressure. Heavier tasks such as video editing, modern gaming or running virtual machines will exhaust the capacity and cause paging. The lack of a heat spreader limits sustained high-load stability in tightly packed cases.

Questions about this item

Does the 288-pin DDR4 module fit a standard desktop DIMM slot?

Yes, the 288-pin DDR4 form factor matches standard desktop DIMM slots.

How do I enable the Intel XMP 2.0 profile on this CL19 kit?

Enter the BIOS, locate the XMP toggle, select Profile 1, save and reboot; the module will then run at DDR4 2666 with CL19 timings at 1.20V.

Will the lack of a heat spreader shorten the lifespan of these 8GB sticks?

No, the unbuffered DDR4 ICs are rated for continuous operation at 1.20V without a spreader under normal case airflow.
