8GB DDR3 1600MHz SODIMM laptop module

This A-Tech module provides eight gigabytes of DDR3 memory in a 204-pin SO-DIMM form factor. It runs at 1600MHz with CL11 latency at the standard 1.5V voltage. The stick is unbuffered, non-ECC and built with major-brand chips for AMD and Intel platforms.

Fits HP part numbers listed.

The module matches HP part numbers such as 656291-150, 667217-361, 667217-961, 670034-005, 689374-001, 691160-965, B4U40AA, H2P65AA, H2P65AT, H2P65UT and H6Y77AA. Systems that require ECC or registered memory cannot use this unbuffered non-ECC stick.

Single-rank versus dual-rank organisation

This unit uses a 2Rx8 configuration, meaning it is a dual-rank module. Some laptops only accept single-rank SO-DIMMs, so verify the motherboard documentation before ordering.

Questions about this item

How do I install this 204-pin DDR3 SODIMM into my laptop?

Power off the laptop, remove the battery if accessible, open the memory compartment, align the module notch with the slot key, insert at an angle, and press down until the retaining clips snap into place

What maintenance or replacement will this 8GB DDR3 1600MHz module need over time?

No routine maintenance is required; keep the contacts clean and ensure the laptop cooling system stays clear of dust to avoid thermal throttling of the memory

What limit appears first when this CL11 1.5V module runs sustained workloads?

The DDR3 1600 speed and CL11 latency set the bandwidth ceiling, so prolonged heavy multitasking will hit throughput limits before voltage or temperature becomes an issue
