Targeted DDR4 SODIMM for HP ProBook G7

This 8 GB DDR4-2666 SO-DIMM is built for HP ProBook 430 G7, 440 G7 and 450 G7 notebooks. It delivers 260-pin unbuffered memory at 1.2 V with CL19 timing for owners of those specific models who need a straightforward capacity increase.

Upgrade path from 4 GB or 8 GB

The laptops support two sockets and a maximum of 32 GB. Adding this module to an empty slot or replacing a smaller stick raises total memory, and the system will run all modules at the slowest installed speed or the processor limit.

Simple slot installation

Insert the stick into the SODIMM slot at the correct angle until the clips engage; no tools or configuration are required. Mismatched speeds or exceeding the two-socket limit are the typical issues that prevent the system from recognising the new memory.

Questions about this item

Does this 260-pin DDR4 SO-DIMM fit the memory slots in an HP ProBook 430 G7, 440 G7 or 450 G7?

Yes, the module is built to the 260-pin DDR4 SO-DIMM form factor used by the ProBook 430 G7, 440 G7 and 450 G7, so it seats directly in their SODIMM slots.

What is the correct way to seat the stick, and what step do people often miss?

Align the notch with the key in the slot, insert at a slight angle, then press down firmly until both side clips click — the click is the step many forget.

When will this 8 GB module need to be replaced or upgraded?

The ProBook 430 G7, 440 G7 and 450 G7 support up to 32 GB across two slots, so you would only replace this stick if you later want more capacity or a matched pair for dual-channel performance.
