pushing the limit ...

[i686]

hi'
as you can see on my sig, I have a prescott OC @ 3.8.
now, I see that the voltage isn't this stable, so I turn it to 1.5v,
base is 1.42v.
I'm on air, I can push the fsb to 250 with a ram 1:1.
just afraid of high temp.(over 60°c on load)

the question is how far can I go riskless with the voltage of the cpu to reach this 4ghz?
will it affect the agp and pci if they are left to default settings in bios?
since I put 1.5v the temp didn't change.
and the system is a bit faster too ... cpu works easier.
max under prime, everest looking ... 49°c

anyone has an advice?

ps; will change for a core2duo, but it's not for right now ..

You should lock the AGP/PCI to 66/33 in the BIOS. As for voltage,,, the more voltage you give the shorter it's life will be. IIRC around 1.55 volts max for air.

Get a bigger/stronger fan on the Typhoon. My old 3.2e would crash as soon as temps go past 50C. The biggest problem you will have is keeping it cool. It is a Preshott after all.

There is also the Vdroop mod which will keep your Vcore from drooping under drooping under load. All Asus boards have Vdroop designed into them to protect CPU from high voltage, you can fix with a 28K ohm pot (IIRC).

hi'
thanks for fast reply
alright, so I'll stay @3.8, because I can't afford a major upgrade right now, meaning mobo, cpu, ram ddr2, and a pci express video card like the nvidia 7900gt as I thought earlier
and for sure I don't want this cpu to fail ...
so, 1.50v should be enough to keep it running riskless.
I needed to know this, thanks again

it's running fine by now, so let it be this way until money is enough to jump on an upgrade
