4GB DDR4 2666MHz Desktop Upgrade

This single 4GB DDR4 DIMM runs at 2666MHz with CL19 latency and standard 1.2V operation. It is built as an unbuffered non-ECC module using major-brand chips for broad AMD and Intel desktop compatibility. The 288-pin form factor fits mainstream desktop motherboards that support DDR4 memory.

Replaces Kingston KVR26N19S6

It serves as a direct equivalent for the listed Kingston part numbers including KVR26N19S6L/4 and KCP426NS6/4. The upgrade is worth it when your system currently runs less than 4GB or uses slower DDR4 speeds, allowing smoother multitasking and faster application loading. Verify your motherboard's maximum supported frequency and capacity before purchasing.

Simple DIMM installation with common pitfalls

Installation requires aligning the notch on the 288-pin module with the slot key and pressing firmly until the retention clips click. Common issues include seating the module incompletely, mixing mismatched speeds which forces the system to run at the lowest common rate, and exceeding the board's maximum capacity per slot.

商品問答

Will this 288-pin DDR4 DIMM fit my desktop motherboard slot?

The module uses the standard 288-pin DDR4 DIMM form factor, so it fits any desktop board with a DDR4 slot.

Which way does the notch on this CL19 module align during installation?

Line up the off-centre notch on the gold edge with the key in the DDR4 slot, press straight down until both side clips click — do not rock the stick.
