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.

Questions about this item

Does the 1.2V DDR4 module run cooler than higher-voltage RAM in an HP ProBook 630 G8?

The 1.2V DDR4 3200 CL22 SODIMM operates at standard JEDEC voltage, so it draws no more power than the factory memory and produces no extra heat during all-day use.

Will this 260-pin SODIMM work in an HP ProBook 635 Aero G8 without any other parts?

Yes, the 32GB DDR4 3200 CL22 1.2V module is a direct drop-in upgrade for the ProBook 635 Aero G8; no additional components or adapters are required.

Can I keep the original 8GB stick and add this 32GB module in an HP ProBook 640 G8?

The module is 2Rx8 CL22 at 3200 MHz; mixing ranks or timings can force the system to run at the slower stick's speed, so matching capacity and spec is recommended for stable dual-channel operation.
