32 GB DDR4 kit for HP Omen Obelisk

This 32 GB kit contains two 16 GB unbuffered DIMMs built to DDR4 2666 speed with CL19 timing. It is designed for HP Omen Obelisk 875-1xxx and Pavilion 690-0013d systems. The modules run at 1.20 V and use major-brand chips.

DDR4 2666 bandwidth and platform ceiling

The DDR4 2666 standard delivers a peak transfer rate of 21300 MB/s per module. Total throughput is capped by the memory controller in the host system, so installed modules cannot exceed that controller limit. Mixing speeds forces all memory to run at the slowest installed rate.

64 GB maximum capacity across four slots

The supported platform accepts up to 64 GB total across four DIMM sockets. This kit fills two sockets with 32 GB, leaving room for another matched pair to reach the limit. Builders needing more than 64 GB must choose a different platform.

Perguntas sobre este artigo

Should I choose the 32GB (2×16GB) kit or a single 16GB module for my Omen Obelisk 875-1xxx?

The 32GB kit provides two matched 16GB DIMMs for dual-channel operation, which the board supports across its four slots; a single module would run in single-channel mode and leave capacity unused.

What does the DDR4-2666 CL19 rating deliver in an actual Omen Obelisk 875-1xxx desktop?

The modules run at 2666 MT/s with 19-19-19 timings at 1.20V, giving the rated bandwidth of PC4-21300 when the CPU memory controller supports that speed.

Does the 288-pin DDR4 DIMM interface limit the speed on my Pavilion 690-0013d?

The 288-pin DDR4 DIMM form factor carries the 2666 MT/s signal; the practical ceiling is the processor's memory controller, not the DIMM connector itself.
