Is the 10-15% rule universal when I comes to raising the v-core?

I have a stock running 2600+ Barton, with a Thermalright SLK-900A, drawing off an Antec True-Power 450W PSU, currently operating at ~30c idle, >40c load.

I wanna turn this ***** up, but after I fried my last CPU and ATI 9600Pro :cry: last week, due to bumping the vcore too much and/or my crappy 350W "Came-with-the-case" PSU, I'm a little fearful now as to how far I can go.

Not really, I suppose it all depends how much you are willing to risk.
I highly doubt too much cpu vcore killed your vid card- in fact its next to impossible.

With your cooling I would max out at 1.85v daily or 1.9 for benchmarking. You could go up to about 2v with subambient cooling.

OK thanks for the info.

As far as the vid card goes, I think the increased vcore had at least an indirect responsibility for its demise. The only thing I can think of is because I put so much stress on the 350W PSU, (overclocking CPU and GPU, raised vcore, 4 case fans, 1 big Tornado HSU fan, GPU silencer, etc.) that my PSU decided that it had had enough, and took my CPU and vid card with it. I HOPE thats what happened, anyway.

Two things damage a cpu chip through normal operation. Temperature and electron migration (and I guess falling if you plan on dropping it ;) )

Electronic migration occurs more often as you set volt core higher, but doesn't happen significantly at lower temperatures.

High temps can hurt the core because they speed up em and I believe stress the connections.

So when it really comes down to it, the safe vcore of a chip depends on the type of cooling you have on the chip, and the temperatures the chip runs at at idle/load.

nealric is right... I haven't heard of voltage killing an agp card or memory in a while.
