OWC 32GB DDR4 3200 CL22 1.2V 260pin SODIMM HP ProBook 630 635 640 650 G8

32 GB DDR4 SODIMM for HP ProBook G8

This 32 GB DDR4 3200 MHz CL22 module is built for HP ProBook 630 G8, 635 Aero G8, 640 G8 and 650 G8 laptops. It runs at 1.2 V as a non‑ECC unbuffered 2Rx8 SODIMM with 260 pins. The kit targets professionals who need more memory for multitasking and larger datasets on these specific platforms. Buyers whose notebooks require a different pin count, voltage or form factor cannot use this module.

Sustained load behaviour

At the rated 3200 MHz PC4‑25600 speed the memory maintains JEDEC‑compliant timings during extended workloads such as compiling code, rendering video or running virtual machines. The CL22 latency stays consistent because the modules are validated at full speed rather than tested only in short bursts. Systems limited to lower memory frequencies by BIOS or chipset will downclock automatically.

Thermals noise and power

Operating at 1.2 V keeps power draw low and eliminates the need for a heat spreader in the thin chassis of the supported ProBooks. Without a spreader or active cooling the modules run silently. The low voltage also reduces thermal load on the laptop’s shared cooling system during prolonged use.
