Hi all

Ive got a new mobo coming - a dfi ultra d which will allow me to put stupid volts through the 3500+ albeit on air. I can at the moment get suicide shot at 3246MHz on 1.66v...and SuperPI upto 3045MHz - what do you guys think I will get on 1.8v for both suicide and SuperPI? ATM the best SuperPI I got was 28.1s using BH5 RAM and a Gigabyte NForce3 250GB Motherboard. :)

Regards,

thanks

i have seriously thought about improving the cooling but even with 1.66v it idles at 30c or so with a £3.50 Akasa heatsink. I dont expect to super pi at 3.2 gig but I will see what it can do.
 
well it turned up.

I set it up and installed the drivers.

now I try putting 1.73v through the CPU and it just reboots instantly when running SuperPI but 1.65v works fine? even my old gigabyte K8NSC939 could do this. What is wrong? can the chip just not handle the .3 of a volt more than before? the temps are 32c or so. I tried running 3022MHz on 1.55 that works fine so does 3030 on 1.55v but at the speeds that definitely superpi at 1.55v will just obtain an instant reboot when set to 1.73v? Any clues as to why?

Also, what memory voltage is it that I need to move the jumper so it takes it from the 5v rail isntead of the 3.3v?

got another 9MHz I think from the suicide shot. http://valid.x86-secret.com/show_oc.php?id=236769

The chip probably can't handle that much volts. I would never put 1.73V through the cpu as it would probably kill it quite quickly, especially as your only using a cheap akasa air cooler.

Even though the temps are low that amount of volts can still kill a chip.

thanks mate , im not using that vcore again - max Im using is 1.66v.

The temps are incredibly low for such a massive amount of voltage. What are you using to monitor them? Try CoreTemp instead and see what that reports.

Lee is right also, voltage can kill the chip alone. It may be that the chips inbuilt safety controls are just turning the thing off before it fries itself.

cheers bud.

Im using SpeedFan to monitor them, will fire it up in a sec and see what the temps are with 1.66v. Remember though, they were only idle temperatures and the only load I run with this amount of Vcore is SuperPI
 
whatever went through the chip was definitely too much voltage, now it wont benchmark at the right speed lol..

I read on XS that the mobo can overvolt the CPU a bit by upto .8 of a volt...so I could have had 1.82v through it, not suprised this has happened tbh, ah well at least its old stuff.
