Ready for HP ProBook 650 G2 and 655 G3

This 16 GB kit (2 x 8 GB) is built for the HP ProBook 650 G2 and 655 G3. It uses 260-pin DDR4 SO-DIMM modules running at 2400 MHz with CL17 timing. The non-ECC, unbuffered design matches the factory specification for these notebooks.

Fits both SODIMM slots on the motherboard

The two modules fill the available slots on the ProBook 650 G2 or 655 G3, reaching the platform maximum of 16 GB. Each stick operates at 1.2 V and uses a major-brand chipset in a 2Rx8 configuration. No heat spreader is fitted, keeping the profile low for tight chassis clearance.

Steady throughput at rated speed

At DDR4 2400 the kit delivers consistent bandwidth under sustained workloads. The CL17 17-17-17 timing and 1.2 V operation keep latency stable during long sessions. The unbuffered, non-ECC design is suited to everyday productivity rather than error-correcting server duties.

Questions about this item

Will the CL17 latency and 1.2V voltage limit performance during sustained workloads?

The modules run at CL17 timing and 1.2V, which are standard DDR4 specifications for stable operation under continuous use.

How much heat or noise do these sticks produce when running all day?

The kit has no heat spreader and operates at 1.2V, so it generates minimal heat and makes no noise during extended sessions.

Which laptop models must I already own for this 260-pin DDR4 kit to work?

This memory is validated for HP ProBook 650 G2 and 655 G3 systems with two SODIMM slots.
