HP Pavilion 690 & TG01 Upgrade

This 16 GB DDR4 DIMM is built for HP Pavilion 690-0022na, 690-0050nf and Pavilion Gaming TG01 desktops. It installs in a 288-pin slot and runs at 2666 MHz with CL19 timing. The single stick adds 16 GB to the two-slot motherboard.

Capacity Limit & Pairing

Systems capped at 32 GB with two sockets can use this module to reach half the maximum. Buyers needing the full 32 GB must add a second stick. Mixing brands is possible but all memory will run at the slowest installed speed.

DDR4 2666 CL19 1.2 V Spec

The module operates at 1.20 V, is unbuffered, non-ECC and uses a 2Rx8 rank. These electrical and timing parameters decide whether the motherboard will accept the stick without configuration changes.

Questions about this item

Does the single 16GB stick ship alone or with extra hardware?

The package contains one 288-pin DDR4 DIMM rated at 2666 MHz CL19 1.20V; no cables, screws or heat spreader are included.

Should I pick the 16GB module or add a second one for 32GB total?

The desktop has two slots and supports up to 32GB, so a second identical 16GB stick gives the maximum matched-pair capacity.

Will the CL19 2666 MHz rating actually run at that speed in my Pavilion 690-0022na?

The module is validated for that platform and will operate at 2666 MHz CL19 provided the CPU memory controller also supports 2666 MHz.
