I mean, if I raise my FSB, fully knowing that I would have to raise my v-core voltage (depending up on how high I raise the FSB too), to have any stability at all, how many +5% voltage increases could I give it, before it completely burns up? And also, when I reached that plateau, would it burn up on boot up alone? Or would I have time enough to monitor the temp and shut it down? Just curious.

Never tested that out...lol! You'd have to do some searching to see what others have been able to get away with. Personally, I've never worked with a board that increases the vcore in percentages.
Let's look at this using some basic math skills. 100% of anything is that same as multiplying by 1. If you have a total of $100, 100% of that total would still be $100, correct? If you have 5% of that $100 total, you'd have $5...are you following me? Another way to write 5% would be 0.05, so $100 x 0.05 = $5. OK, if you were to increase your $100 total by 5%, how much would you have? You'd have $100 + $5 = $105. Another way of putting it would be $100 x 105%...which is the same as $100 x 1.05...is this making sense?

Now let's apply that to your vcore. Let's say your CPUs default vcore is 1.65v...if you increase it by 5%, you'd have 1.65v x 105% or 1.65v x 1.05 = 1.7325v. If you went with a 10% increase, you'd have 1.65v x 1.10 = 1.815v.

jam,

I need to go back and re-think my question.

Sorry for taking up your time.

sorry, did I confuse you? LOL. Use the following to arrive at the new vcore value

5% increase = default vcore x 1.05

10% increase = default vcore x 1.10

15% increase = default vcore x 1.15

20% increase = default vcore x 1.20

As to what voltage will actually fry your CPU, it's hard to say. I've seen reports of people raising the Tbred vcore as high as 2.0 - 2.2v

So working in reverse & using 1.65v as the default & 2.2v as your max:

2.2v/1.65v = 1.3333, so 2.2v is 33.33% increase over the default

The 10% rule is pretty save. 10-15% you'd better have good cooling. Over 15%, take your chance to upgrade CPU prematurely.

Now I can work with those numbers.

Thanks for the advice guys.
