What happened to your lightnings? Got tired of waiting for the EK waterblocks? They're right around the corner. Hopefully Monday we'll see them. I've got 4 lightnings I'm planning on watercooling, but I also own a Sapphire Dual-X OC 7970 and an AMD DCII TOP 7970

I got tired of waiting for the blocks (and I can't put those hideous crop circles in my rig) plus I wanted a D/L DVI port for my S27A950D. I also heard that the Sapphire 7970 Dual-X OC's were some of the better clockers around (one of my Lightnings wouldn't do 1220MHz even at 1330mV). I'm still hoping that a fresh, stripped down OS install along with the latest 12.7 beta drivers will help my scores a bit...

You mean the AMD one?

I tried it and do you just simply let it run a couple of times? I got through it and the educational portion without issues.

Ah didn't notice it, but his Tess on Extreme with 1000/1350 seemed a bit low as well.

 

Yeah im def going to swap out my card. I have never had this many issues before which is annoying. I would just return it but I gave the games away so I can return it for something else. I will just swap it out with newegg and grab another msi 7950 and see what happens. IMO and im being blunt and honest. this 7950 runs like junk

I currently have a Gigabyte 7950, and its oc'd to 1250/1900 @ 1.3v. But the only way for me to do this is by using Trixx (OC) and Afterburner (voltage). I wish to only use one program. Is there a way to get Afterburner to go past the set limits of 1100/1575?

Use unofficial overclocking method. There is a missing .dll on the newer versions of AB though so you will need to find 2.2.1 or earlier.

Yep you just let it loop for a while.

What does this missing dll actually do? Help enable unofficial oc? I am using 2.2.3 and everything seem to work fine.

Currently running the new unofficial Beta drivers from Guru3d forums, so far no problems, but I haven't tried out any games yet since I've just reformatted.

It's a shame that you're experiencing all these problems, hope your next attempt is more successful.

It allows you to set a higher clock speed iirc. Still have to use UOM but even with UOM you can't raise clock speed with 2.2.3 as I understand it...
