too much voltage?

[tim-may]

i was reading up on some Vcore mods for my A7V133 and i had found a few good ones. with the 3 mods, i could potentially break the 4 volt barrier going to my processor. this is very unusual for me asking this but....how much is too much??

It's hard to say for sure.

My take on it is similar to what the Pentium is going through: because of the new .13micron process, 1.8V is about the maximum safe voltage that one can apply. People at OC are discussing this now. It seems that the throttling in the pentium, which keeps it from burning itself up, has the side effect of not preventing overvoltages to damage the CPU.

For AMD, there is no internal throttling, and any protection circuit needs to be on the mobo, as it reads the new Athlon's internal diode (and immediately shut down, on an overheat). So our AMDs don't suffer from the same problem that the Pentiums do, but they don't loose any data.

For us AMD'ers, it comes down to a balance between keeping the CPU cool, by any means necessary, and applying power. Overall, 95+ degC will fry an Athlon, and anything above 65C, can significantly reduce the lifespan. 45C however is a very comfortable temp for the Athlon, for operation and longevity.

So if you can keep your temps around 45C, then I think that you'll find that the max voltage that you'll be applying will be very near 2.00 V.

thx bigben for the ideal temps, but this is a 'what if' scenario.

here is what i plan on adding:

i honestly dont like the dip switch idea though.... i dont like having the ability to give the proc a variable voltage. but a duron 700 at 1ghz is a very inspirational feat. All of the pages mention putting a resistor on the voltage controller chip on the riser card to ground. this seems to be the biggest boost. Also, it seems that the voltage tends to swing a lot. is this ok???

i crunched some numbers with Radiate, and im getting almost 500 watts of heat at the 4v mark at stock (1.46GHz), but that gets even worse at the 2ghz mark, which is what im shooting for.
The amount of heat hits 665 watts.... Would a 220watt peltier handle this at either speeds?

seriously......don't go above 2.5v
