You are going to kill yourself because of that? What are you going to do if the cards can't perform as this post #52

 

Ok don't tell me. Must be scary.

There's plenty of 7970's out that will clock that high. Why do you need that Sapphire? My Diamond and Visiontek both can clock that high, but I don't run them like that. Running 1200/1600 is plenty with Crossfire. Have you heard the coil whine yet. At 1300mhz, there gonna be screaming lmaosmiley.gif

Memory is 1637 also stable at 20% in extreme kombustor.
I have room for the core but not the memory, I'd like to get a good 10% more increase until I get two more 7970's with my new mobo, then I'll scale back slightly.
Thanks.
Edit I've never done any BIOS flashing etc, so I'd like to keep it simple. I'm running a 64bit windows 7.

Easy, crank the voltage up to 1.300v and see what it can do. If you can't clock any higher, then you need to keep it cooler.

Opps, Sorry about the double post redface.gif

No, MSI Afterburner has a limit with 1200 core clock and 1650 memory clock :\. My temps are fine in a single gpu config, FOR NOW.

Also what is this coil whine? Never heard such a thing from my card yet :\.

No coil whine on any of my Sapphires, although the 1st one I bought did have on my old PSU.
It was a 750W Ennermax Noisetaker. Nothing on new PSU.

Hard to notice it with the reference cooler , in my case when i switched from the reference to the Accelero i found out my 7970 (1230/1600 1.17v) got the coil whine too ;(.

Ill put it to u this way. I have never won any money on a scratch off in the 25 years i have been alive ( probably over 50 scratch offs). That is the luck i bring to the table lol. Its not about sapphire really, it could be any vendor i just need the assurence that i will be able to hit those clocks. If they scream i hope it sounds like a cat, that way, it will keep the mice at bay

I have a windforce 3 thingy, the triple fan cooler from gigabyte. Not as quiet as yours but eeh. What does it sound like ph34r2.gif. Do any other card experiance this or only the radeons.

Uninstall Catalys and Afterburner. Flip the BIOS switch to #1 then run this:

Tahiti_XT_C3860100_X00_BIOS_Dec20_2011.zip 420k .zip file

 

Reinstall Catalyst followed by Afterburner.

No it doesn't.. You need to unlock it. My Afterburner goes to 2000 core and 2700 mem.

Close afterburner, Go to computer/ C: / Program files (x86) / MSI AFTERBURNER . You need to go to the bottom of the cfg file and change Unofficial Overclocking Mode from 0 to 1 and the save the file. Open Msi Afterburner and the hit Yes to the message.

WALLA, 2000+ core 2700+ mem thumb.gif

@ Ken1649, what does that do instead of just unlocking AB? Unlocking AB has done everything I need without flashing the bios. I only flash bios if that's last resort

@ jomama22, so your not lucky your telling me. Ok. What makes you think your going to get cards guaranteed to run those clocks? Does sapphire say their cards will do 1300core or your money back?

@ Stu-Crossfire, your cards are on air. The fans are louder than the coil whine. I didn't hear any either until I put mine on water. They make noise for sure and the higher you clock them the louder it gets.
