Sapphire HD7970 DUAL X OC Settings

Hey guys,

I OC'd my Dual x 7970 from the AMD Catalyst control Center.
I just want to know if the boost i gave it is good or should i lower the settings. The default settings were:
High Performance GPU Clock Settings: 950 mhz
I put it on 1150 mhz
High Performance memory clock settings: 1425mhz
I put it on 1600mhz

I ran Tomb Raider on ultimate settings and the temps were 54-58 degrees Celsius. Fan speed was 53-56%.

Idle temps are 37 degrees, idle fan speed is at 25%

Are these numbers good? Should I change something?

Thank you in advance for your help.

Looks really solid. The 7970 boost is great at stock but those overclock temps are excellent. Did you try running a GPU stress test for stability?

No, I haven't. I did this just before I had to go to work, so I had no time.
Which stress test would you recommend?
And thank you for your quick response!

Definitely run FurMark.

Should I do it at stock first and then gradually increase the clock speeds? I'm sorry for all these questions, but this is my first time OC'ing. I have a general idea of the concept, but I want to be sure about what I'm doing.

Usually you increase one variable at a time. Such as increasing the clock speed. Then once you have found a stable level back up a little bit from that. Then do so the same for memory. Once done, set your GPU to those settings you found and try the FurMark test again. Look for any artifacting or issues in quality. If so, then back down a little bit.

I prefer a modest overclock. Cuz at some point you really aren't going to get much more improvement. at the same time, you'll be increasing the heat so you gotta pay attention to that.

I haven't used Sapphire utilities for GPU usage. But I'd suggest making a custom GPU fan setup. Essentially you set a graph to adjust fan speeds for temps. This helps a lot in my opinion. I'd do this step first.

Will follow your exact instructions!
I'll probably just give it a very minor OC since I don't have any complaints with the performance on stock settings.(BF3- averaging 100 FPS - 1080p on Ultra).
And when i drop below 60fps on future games, i'll just get another one or replace it with an R9 290x.
Thank you very much for your answers!

100fps in BF3! wow. Then again it's probably worthless cuz most people game on 60Hz monitors. That's why I'd do a very modest overclock and leave it at that. If you need to push it then adjust it later, in the meantime a 7970 is more than enough at stock. I was thinking of getting one and leaving it at stock so I don't have to buy a new PSU for it.

Have you tried BF4 yet? I'm gonna wait for more benchmarks before I decide whether I should buy a 7970 or keep my 660ti.

I played the beta for 30 minutes. Didn't even have fraps at the time to check fps. But i put it on ultra graphics and it was excellent. No problems at all.
If you've got the money, I would think you should upgrade. If not the 7970 you could get the R9 280x. I've read a lot of good things for this card!

I hope you got the 7970 recently. The price drop is insane to me. It used to be this high end expensive GPU for $500. Now you can get one for $280. It's awesome!

Does Sapphire have software that allows you to create custom fan profiles? I'm not familiar with their software.

I did get it recently. But unfortunately where i live(Cyprus), electronics prices are way high. I got it for 419 euros, which is more than $550.. They still sell the Titan for 1050 euros, which is around $1400 i think.. INSANE! The PC i build would have cost me about 40% less if i was in the USA or UK.

Yes, Sapphire have the Trixx Tweak Utility:

It controls everything you would need.

I don't live in US either. Most buyers are from US on this forum so I just assumed you were. I will be in the US in January so I was thinking of picking up a 7970 while I was there.

I glanced at the software images and I saw their is a feature that allows you to customize the GPU profile. Do it. Before, I thought you had to buy fans to keep your GPU cool, but later realized that you can tweak the GPU software a bit and get better results.

Yeah, I'll do it tomorrow probably. It looks like a nice and simple program.
Lucky you. Hey, you might as well get 2 of them and throw in a PSU! :)  Next time I'm in the US, I'm just gonna buy PC parts, even if i don't need them!

^ agreed. Sucks that components aren't the same price everywhere. The only issue with buying and leaving is that if things fail you have to ship them back.
