How do you know what is a safe 24/7 overclock.

Hi
As title really was wondering how this Is figured out how do you know what is a safe 24/7 clock regarding volts,core clock and memory clock?

I'm guessing with volts it's the guideline of not above 1.3v also tied in with temps but what are exceptable core and vrm temps?

How do you decide what is a benchmark only overclock and what is a 24/7 clock?

I currently own a 7950 wf3 I run this at 1150/1500 @1.23v 63-64c underload 73-74c on the vrms is this considered a 24/7 or benchmark clocks?

Thought this may also help other people wondering also.
Thanks for any info all help is appreciated.
 
That's fine for 24/7. I wouldn't be comfortable going above 1.25V for 24/7 if temps were above 70C tbh, but with those temps and volts you're doing quite well. Especially to have your VRMs that cool at those volts. My MSI VRMs went to 105C at 1.2V and that was after 10 seconds of Heaven 3.0!
 
For mke at the moment on 7970:
Temps under 70c
25mhz back off from first signs of artifacts
10-20 loops of heaven for testing + a few hours of a stressful game to confirm.
 
I just play games and so long as the temp remains at under 70c (air cooling) and the game does not crash after a few hours, I consider this a stable 24/7 clock. Some games are more stressful than others, so I would be using a very heavy GPU intensive game.
 
I've run heaven a few times and was fine and been playing metro 2033 with everything on max (recently activated triple screen buffing in ccc as I was getting screen tearing which resolved the issue)

I had the memory at 1550 at one stage and seemed stable for hours but lastnight got a grey screen with lighter grey lines going down the screen!(guessing this is a memory being pushed to far issue) So backed off to 1500 and played for another hour or so and seems fine will see I suppose.

Been using metro 2033 as it looks like its pretty gpu intensive uses 99% according afterburner is this a decent game to stress test on?(looks beautiful)

I do the same. Run heaven a few times to gauge temps, and if all is well I blast a game. Metro is very demanding alright, so it makes a good test.
 
just checked my volts I'm actually running 1.237v.
But I think I could bring this down as I was getting stuttering/ unsmooth gameplay and artificing in metro 2033 (only in that game) was quite weird actually regarding the artificing even when I went back to standard clock speeds it did it untill I restarted the pc! and just slapped another .37v and it resolved it may try to bring it down a little.

1.237v sounds very high for an 1150 clock. All cards are different and all that, but mine'll do 1150 on 1.131v 24/7.

I will have a play tonight and see if I can lower the volts the ASIC on my card is awful though (59.9%) not sure if this truly makes a difference though.

The volts you have set yours at are pretty much my default voltage!!

Ah, that makes a bit more sense. My stock voltage is 1.056v I thinik.
Do you have a low asic score? Mine's 87.3 iirc.

lol
 
have managed to get the volts down to 1.218 instead of the 1.237 seems stable so far in metro only managed to play about 30 mins so far but had no artifacts or lock ups.
