Hi guys,
I've been playing around with overclocking my graphics cards over the last few weeks.
I've been using Sapphire's triXX program. Reason being, after extensive research seems my particular make of graphics cards have locked votlage controls, even after you put the special phrase into the MSI afterburner config and disable ULPS. MSI afterburner, although it would let me put the clocks up to 1200mhz wouldn't let me change the voltage at all.
I'm also pretty sure mine are laser cut and won't unlock to 6970's, and tbh I'm not interested in trying this anyway for the time being.
Now TriXX will let me up the voltage, but only to 1.18v.
I can get it to bench 3dmark11 at 900/1360 I believe. Any faster and it will lock up.
Now in games on stock volts BF3/MS Flight were crashing all the time at 900/1350, after upping the volts to 1.18v with +20% power it run MS Flight last night for an hour no problems, but after playing Shift 2 Unleashed for about 10-15 minutes I got a BSOD.
I have dropped the clocks down a touch this morning to 890/1350 and will do more testing over the weekend.
So firstly, I am assuming my crashes are due to the lack of voltage at those clock speeds? - I'm 100% stable at stock clock speeds/also was stable at 860/1325 stock volts after many hours of BF3. I cant push the memory clock really any higher then 1350 or I get the off centre split screen thingy some people have reported.
Secondly, (and I appreciate it varies per card really) to save me possibly weeks of trail and error tweaking, anyone got some good stable clock speeds with 6950's on TriXX? Like would I be better off dropping the memory clock right off and upping core/or visa versa rather then trying to slowly adjust both?
Also temps wise, absolute max I have ever seen on all tested speeds/voltages was 73c.
