Hello Everyone/Need OC Help

Recommended Posts

First I would like to say hello to the community and give my thanks in advance because without all of you, people like me would be stuck raging trying to fix this problem without the proper knowledge. So I'd like to describe my issue.

 

I currently run a Sapphire 6970 Flex and everything runs perfectly when set to overdrive setting in the Catalyst CC at a max (950 GPU clock) and (1450 memory clock) the bar does not go any further is the catalyst. I tried using the TriXX utility and anytime I go past the 950/1450 settings it becomes unstabble and glitchy causing screen tare.

 

Comp Specs:

 

Motherboard: Asus-P8 P67PRO B3 Revision (updated Bios)

CPU: Intel i7-2600k CPU @ 3.40Ghz (No adjustments made)

GPU: Sapphire HD 6970 FleX (Idle at 49C with stated OC settings)

System Memory: 4x4GB Corsair Vengeance

PSU: Corsair TX850

OS: Windows 7 Ultimate 64-bit

Catalyst version: 12.10

TriXX version: 4.3.0

 

Cooling:

Large Coolermaster Case (Plenty of airflow with a proper wire tuck)

Corsair H60 Hydro CPU Cooler

 

Any input is much appreciated.

So what is the issue? You just want a higher OC?

 

I'd say spend that time overclocking your CPU first before worrying about the last percent or two on your GPU clocks. :P

Well my issue is after seeing the OC settings posted on this card on the review here I figured I should be able to run mine stable at something close to that or is that a silly thing to assume?

Every card is different. Some will overclock well, some almost don't overclock at all.

 

 

Maxing out the sliders in CCC is already something to be proud of for the most part. :cheers:

 

 

That said, you should be able to do a bit better with TriXXX. Are you changing the voltages at all or the board power limit?

I have adjusted the voltages on the card and it still causes the same screen tare effect and I read that my card can operate at a voltage of roughly 1.275V. I have not tried changing the board though. Im not sure what id change and what a safe voltage would be.

Screen tearing is your only issue? As in frames out of sync?

 

Just enable Vsync - you'll get frame tearing any time your frames per second exceeds your monitor refresh rate without it.

I have a 2ms LED Samsung Monitor so I'm not sure if that should matter. I get screen tearing on the desktop and especially when I open Firefox.Its like a flickering/tearing.

Oh...well that's another issue entirely (screen distortion). Do the higher clocks using TriXXX work in games without crashing or graphics glitches?

If I adjust past 950/1450 OC settings I am required to restart my comp to get rid of the distortion even if I restore back to 950/1450 before restart. I run my games fine at 950/1450 yes. I don't bother trying above that because if its distorting the screen before i even launch a game i figured it be pointless to try gaming doing so.

That sounds unstable then. :lol: I'd just forget about getting that last little bit from the GPU and focus on overclocking your CPU. You've got a decent cooler, a good motherbaord, and a highly overclockable CPU. :biggrin:

Okay thanks for the input and I have just begun reading about OC the CPU and it looks fairly easy. I'm just curious though as to why on this site the review for my GPU showed much higher OC settings and at a stable state.I get it now ever card is different but he was able to OC it to

That's only 48 MHz more than you've got on the core and 58 MHz on the memory. Those small differences would show up in benchmarks but probably never be noticeable in games. He probably just got a good card...some don't even budge from the stock settings so maxing out CCC without changing the voltage is actually pretty good. :cheers:
