Prime95

I just failed a test of prime95 after a 13 hour test, it said i had one error, FATAL ERROR: Rounding was 0.5, expected less than 0.4.
I read stess.txt it recommended upping the voltage, how far up do i up the voltage safely to? What are known safe voltages?

EDIT: this was my latest overclock from 2800 to 2900 on a p4 2.6c

What are you running at now?
Well, some say 1.7, others 1.8.
Most of all I would say it depends on wheather or not you can afford to replace it !
If you can, max it - if you can't, keep it safe (~1.7)
Also the difference that you will see in 100mhz is next to nothing.
I lost a 3.06 that was running at 1.8 BUT I am not sure it was the voltage that killed it.
I guess it depends a lot on your cooling, how far you want to push it.

i dont want to ruin anything of mine, this stuff has gotta last a year or two im broke, my voltage is at 1.49 rite now

after you pass ~1.7 you are in snds territory, so avoid voltages higher than that if at all possible.

ok sounds good, i will try it upon restart

Anything 1.7 or lower should be fine.
set it up around 1.65 and see how high she wiill go.
A 2.6 should do 3 at a reasonable voltage.
Remember to ballance the return vs the risk
Like if your running 3.2 @1.75 volts, but it runs 3 @ 1.6 AOK, your better off at 3
Almost no difference in preformance, and it will last longer and be more stable.

thanks bobo, i will up the fsb tonite to 225 and up the voltage to 1.6 and see how well it will turn out
