Targeted 16 GB DDR4 upgrade

This 16 GB DDR4-2666 module is built for HP Omen Obelisk 875-1xxx and Pavilion 690-0013d desktops. It installs as a single 288-pin DIMM to raise total system memory toward the 64 GB maximum across four slots.

Standard voltage, no spreader

The stick runs at 1.20 V with CL19 19-19-19 timings and no heat spreader. Power draw and thermals stay within normal DDR4 limits for everyday workloads in these OEM chassis.

Single-stick flexibility

The package contains one unbuffered non-ECC DIMM so you can add capacity without buying a matched pair. Mixing with existing modules is possible, though all memory will run at the slowest installed speed.

Questions sur cet article

How do I install this 288-pin DDR4 DIMM in my HP Omen Obelisk 875-1xxx, and what step is often missed?

Power off the PC, unplug it, open the case, align the notch on the 288-pin module with the slot key, press firmly until both side clips click, then enable XMP or verify 2666 MHz in BIOS — the step many miss is confirming the speed after boot.

What maintenance or replacement will this 16 GB 2Rx8 module need over time?

No scheduled maintenance is required; keep dust from the gold contacts and ensure case airflow stays clear. If a memory error appears, the module carries a limited lifetime warranty from Computer Memory Solutions for exchange or repair.

What limit appears first when this CL19 1.20 V kit runs sustained workloads?

The CAS latency of 19 cycles at 2666 MHz sets the response floor, and the 1.20 V JEDEC voltage caps headroom — thermal throttling is unlikely without a heat spreader, so latency and voltage are the first constraints.
