How are you increasing voltage?
Afterburner voltage controls are locked, here, selecting unlock does nothing.
Nevermind, download says v2.1 but it's actually v2.0, downloaded from another source and not it's working.
My default appear to be 1.025v, is that right?
I am tempted to buy a 3rd 580 but concerned that even at 4.2ghz at 2560x1600 it won't be a huge improvement like going from single to sli was.
Does anyone know how 3 way scaled on the 580 and what sorts of cpu speeds and res you need to make it worthwhile ?
So yeah, stick to 2-way SLI we say -- unless you need to break 3DMark records of course![]()
It amazes me that a few years back Jen Hsen was on stage launching a dell machine with the 7900gx2's inside in quad sli and stated that they scaled almost perfectly (which was utter bs). Now fast forward several years and the scaling of the 580 in quad is potentially even worse than its predecessors.
Is it down to drivers or more down to the game engine that scaling above 2 gpu's really falls off? Some would say cpu limitations as well.
So what are you guys able to achieve for 24/7 overclocks?
I've tried a few games but almost everything seems to get some artifacts past 825 with voltage increase and pretty much any memory increase is resulting in artifacts.
So for benchmarking it's great, for gamings the overclock is pretty crap.

But you cant seem to unlock the voltage controls (Or have you?) when everyone else can. Most gtx480's need a voltage increase around 830'ish...
