HP 200 Series Notebook Upgrade

This 8 GB DDR4 SO-DIMM is built for HP 240 G7, 250 G7 and 255 G7 notebooks that ship with a single memory slot. It targets owners who need more headroom for everyday multitasking on these specific models.

260-Pin Unbuffered Module

The stick uses a standard 260-pin SO-DIMM form factor with no heat spreader, so it slides into the sole slot without clearance issues. Major-brand chips run at 1.20 V with CL17 17-17-17 timings, and the unbuffered, non-ECC design matches the platform's native memory controller.

From 4 GB or 8 GB Single Channel

Systems limited to 4 GB or a single 8 GB module gain up to 12 GB total capacity when this stick is added, moving from single-channel to dual-channel bandwidth where the CPU supports it. The jump is worthwhile when the notebook currently has one empty slot or a smaller module and the workload exceeds 4 GB.

Questions about this item

Does the DDR4 2400 SO-DIMM run at 2400 MHz or drop to the CPU limit?

The module is rated for 2400 MHz. All installed memory will run at the slowest speed of the modules or the CPU capability, so a Pentium N5000 or Celeron N4000 will set the actual speed.

Will the 260-pin stick fit the single SODIMM slot in an HP 250 G7?

Yes. The 260-pin DDR4 SO-DIMM matches the single socket in the 250 G7 and the compatible 240 G7 and 255 G7 models listed.

What is the correct way to seat the module so it locks in place?

Align the notch on the 260-pin edge connector with the key in the slot, insert at an angle, then press down firmly until both side clips click. The common mistake is stopping before the clips engage.
