Targeted desktop upgrade

This 16 GB DDR4 DIMM is built for the HP Pavilion 690-0020 and 690-0021nf gaming desktops. It adds a single 288-pin module to systems that ship with two slots and a 32 GB ceiling. Non-ECC unbuffered operation matches the platform's standard memory controller.

Capacity ceiling and speed limit

The stick runs at 2666 MHz with CL19 timing and 1.20 V. Two such modules fill the board to its 32 GB maximum; a third cannot be installed. All installed memory will operate at the slowest module's speed or the processor's supported rate, whichever is lower.

Slot layout and pairing advice

The motherboard provides two DIMM sockets, so this single module leaves one free for a matching stick. Matched-pair installation enables dual-channel bandwidth, while a lone module runs single-channel. A 64-bit operating system is required to address more than 4 GB.

Questions about this item

Will this 16GB DDR4 2666MHz CL19 module run correctly alongside my existing slower DIMMs in the Pavilion 690-0020?

Yes, the system will run all installed memory at the speed of the slowest module or the CPU limit, so mixing is possible but overall performance drops to that lower speed.

How can I verify the 2666MHz speed and CL19 timings are active after installing this CM2048642666DIMM stick?

Enter the BIOS or use a system-information utility; the memory tab should show DDR4-2666 with 19-19-19 timings at 1.20V for the new module.

Does the box contain only the single 16GB DIMM or are mounting brackets or cables included?

The package content lists one memory RAM stick only; no brackets, cables or additional hardware are supplied.
