HP 255 G5 notebook upgrade

This 8 GB DDR3L SODIMM is built specifically for the HP 255 G5 notebook. It uses a 204-pin layout and runs at 1.35 V, matching the platform's low-voltage requirement. The single module fills one of the two available sockets and brings the system to half of its 16 GB maximum.

Sustained workload behaviour

CL11 timing at 1600 MHz delivers steady bandwidth for everyday multitasking and browser-heavy sessions. Unbuffered, non-ECC operation keeps latency predictable during long compiles or video playback. The 2Rx8 organisation spreads access across ranks, helping throughput stay consistent when the CPU keeps the memory controller busy.

Build and daily implications

Major-brand chips are used instead of generic dies to reduce the chance of boot failures or random errors. No heat spreader is fitted, so the stick stays slim enough for the tight SODIMM slot in the 255 G5 chassis. Buyers who want more than 8 GB total will need a second module, and this product does not support ECC or registered operation.

Questions about this item

How much power does this 1.35V DDR3L module draw during all-day use?

The module operates at 1.35V, lower than standard DDR3, reducing heat and power draw during continuous operation.

My HP 255 G5 has two SODIMM slots — can I add this 8GB stick alongside the original module?

Yes, the notebook supports two SODIMM sockets up to 16GB total, so this 8GB stick can be installed in the free slot.

Will the CL11 timing work with the memory already in my HP 255 G5?

The stick runs at CL11 11-11-11; the system will match the slowest installed module automatically.
