Boosting CPU Voltage, how much does it strees mobo?

[geoffry]

I know raising CPU voltage shortens the life of the CPU and pulls more power, but how much would a CPU voltage of roughly 1.5V on a C2D stress the motherboard MOSFETs and all that crap?

I'm thinking of bumping my OC back to my old 3.3 ghz up from 3 ghz on my e4500 till it goes kapoot, then go for a Q9550 (unless of course it stresses the mobo a ton). Voltage required at 3 ghz is low but at 3.3 it takes a bunch.

I've got a GA-P35-DS3R if it matters.

IMHO, it stresses it as much as the extra voltage can stress the CPU. You are running it above designed parameters and there is no set "%" to define extra stress.

However, many boards are designed with overclocking in mind so they are stressed less due to beefier components and design. As long as you accept this extra stress, I would expect the "stressed" motherboard to last as long as the "stressed" cpu. Usually we are talking timespans well past the normal upgrade cycle so you may never likely see the component fail in your useful life of it.

Thanks for the info. This was the first puter I ever overclocked so I wasn't too sure.

It definitely stresses it, as your overclock will pull more juice from the power supply and VRMs. But if your board is designed to work with quad cores, and overclocked quad cores, then I think you can feel safe about upping the voltage on a dual core. Now I think, so if someone has more details on any differences of power delivery between a dual and quad core from the motherboard, then I'd like to hear it.
