System-specific upgrade

This 32 GB kit contains two 16 GB DDR4 modules rated at 2666 MHz with CL19 timings and 1.20 V operation. It is built for the HP/Compaq Pavilion 690-0020 and 690-0021nf gaming desktops and fills the two available DIMM sockets to the platform’s 32 GB maximum.

Straightforward DIMM install

The 288-pin unbuffered DIMMs slot directly into the motherboard without tools or cables. Because the board only accepts two modules, there is no room for error in population order; mixing with existing sticks will force all memory to run at the slowest installed speed.

Capacity locked at 32 GB

Two 16 GB sticks saturate the two sockets and hit the system’s 32 GB ceiling, so no further expansion is possible. A 64-bit operating system is required to address the full amount, and the kit cannot serve platforms that need ECC, registered modules or higher frequencies.

Questions about this item

How can I verify the kit is running at 2666 MHz with CL19 timing after installation?

Open Task Manager or BIOS and confirm the memory shows 2666 MHz speed and 19-19-19 latency; the modules will default to the slowest installed speed if mixed with other RAM.

What exactly ships in the box and is anything else required for the HP Pavilion 690-0020?

The package contains two 16 GB 288-pin DDR4 DIMMs; no extra cables, brackets or tools are needed for the listed Pavilion models.

Should I choose the 2 × 16 GB kit or a different capacity for the 690-0021nf?

The motherboard has two slots and a 32 GB maximum, so the 2 × 16 GB kit fills both sockets and reaches the full supported capacity.
