Upping voltage beyond 1.5V

Happy with current 3.6Ghz overclock but you all know what it's like, I wanna go further :D

I needed to put 1.5v in to get stable at 3.6Ghz (1.5075v in BIOS). Cpuz says I'm idling @ 1.490v & 1.430v under load.

So I have a vdrop of 0.0175 & a vdroop of 0.0775?

Can I up the voltage beyond 1.5v to compensate for this? If so would I just put it up by 0.01v to make up the vdrop or 0.07v to make up for the vdroop?

Just a bit wary of putting too much juice in :confused:
 
As long as you can keep the temps reasonable then I don't see why not. I need 1.53v to keep mine stable at 3.6ghz. Wouldn't go too far above 1.5v though, maybe 1.6 max
 
I've been tinkering with my Q6600 overclock recently and pushed it up to 3.7GHz, I'll check the BIOS settings & uguru/cpuz readings when I get home.
I've prime95'd it and it's solid - I am running it under watercooling though so temps never get too high.

I'll be gradually tweaking this higher over the next few weeks but I'm not expecting to be able to go much higher - I'll be surprised if I hit 3.8 without prime95 failures to be honest. It will be a question of whether the RAM or the CPU starts causing problems first, and I'm not gonna push the RAM voltage up any higher as it would probably start glowing. ;)
 
BIOS CPU 1.6V
BIOS CPU VTT 1.31V

uguru CPU 1.55V idle - 1.49V under load
uguru VTT 1.3V

I'm using an Abit IP35 Pro so it has a number of voltage issues - under voltage and vdroop, so an increased Core voltage helps out, be careful with your own as it may differ. ;)

Running clock speed reported by cpuz is 3707.8 MHz
 
Only managed 3.8ghz on mine, 1.512 vcore in bios, air cooling, ran it daily at 3.6ghz on 1.4 vcore, the voltage jumps tend to get very high after a certain point.
 
So looking at the above & other threads it looks like going over 1.5V is common for getting higher than 3.6Ghz.

Says on the Intel website the max voltage for the Q6600 is 1.5v, has anyone run their systems over 1.5v 24/7?

Just asking as this is my main system & if I do fry my chip I won't be able to get a replacement until after Xmas :eek:

I had my chip at 1.5v for a good couple of months whilst at 3.6ghz with watercooling. Dropped my overclock back now as i'm on air now, but there's nothing wrong with my chip :)
