HP Pavilion 690 & TG01 compatible DDR4 kit

This 32GB kit contains two 16GB DDR4 2666 CL19 DIMMs built for HP Pavilion 690-0022na, 690-0050nf and TG01-xxx desktops. The modules run at 1.20V with 19-19-19 timings and use unbuffered, non-ECC 288-pin layout. They fill the two available slots to reach the platform maximum of 32GB.

Matched pair ensures dual-channel operation

Installing the two sticks together lets the memory controller run in dual-channel mode instead of single-channel. The manufacturer tests each pair for compatibility so mixed-module timing issues are avoided. All installed memory will operate at the slowest module speed or CPU limit, so a matched kit keeps performance consistent.

Low-profile design fits standard desktop slots

Without a heat spreader the modules sit flush in the 288-pin DIMM sockets, leaving clearance for large CPU coolers or tight chassis layouts. The 1.20V operating voltage matches standard DDR4 power delivery on these HP platforms. Builders who need ECC, registered buffering or speeds above 2666 MHz should look elsewhere.

Questions about this item

Will the 1.20V DDR4 modules need any voltage adjustment or replacement as the system ages?

The kit runs at the standard 1.20V for DDR4 2666; no voltage adjustment is required and the modules are covered by a lifetime exchange warranty against manufacturing defects.

What limits sustained throughput on this 2×16GB CL19 kit?

The 2666 MHz DDR4 speed and CL19 19-19-19 timings set the bandwidth ceiling, and all installed memory will run at the slowest module or CPU capability.

How much heat and noise do the two unbuffered DIMMs produce during all-day use?

The modules have no heat spreader and operate at 1.20V, so they add minimal heat and zero noise; system airflow handles the thermal load.
