Not everyone can reach 1200 core, many here can't reach anywhere near 1150 at all.
If you want to reach 1200 core, you most likely have to be ready to throw down a battle with a Gorn biggrin.gif

Actually I did make it to 1200Mhz but @ 1.3v @@ I see people who has the same card like ours, same bio, using same overclock utility, push it to 1250Mhz @ 1.25 rolleyes.gif So I was wondering whether this particular card same some problem or it is just nomal, every card it different? @@

take a look

I received a Sapphire 7950 OC today and so far I got this thing running pretty good at these speeds. This might be a better value then the 7970 currently

I bumped up the voltage to 1.093v

Glad to see you have your OC worked out. but your numbers should be a little better.
I would enable overdrive and set +20% just to rule that out.
You can always disable Overdrive by unchecking the box.
BTW can you enlighten us with the BIOS version your using ? TY
+REP for the previous test you did for me thumb.gif

Yeah AB is pretty user friendly and I'll probably use it for 24/7 use and gaming. I was just hoping to hit some higher clocks for benchmarking purposes. Maybe the next iteration of GPU Tweak will allow Powertune to stay at +20%.

Regarding Metro fps, I wonder if HT is making a difference for the better in your case. I have it disabled.

This is the bios version I'm using.

Thanks for your advice and commentary. I'm really enjoying the community here.

HT is definitely needed to be ENABLED. Its been tested that it works a whole lot better with modern titles.
Try that and see how you go.

Did some tests...... Power tune is needed for anything over 1180mhz....... in benchmarks such as AVP, and GPU tool,Furmark and OCCT.
I tested +5, +10 and +20%
And it stopped performing after 10%
So, ive now set powertune to 10% in CCC and Afterburner Beta 11 is not conflicting with it at all.
I get absolutely zero throttle with 10% engaged.

I ran 3d11 with that power tune at 0 and still scored 9k @ 1200 core with 2500k stock would it matter if I raise it to 10% ?

Two 7970 = four 6950/6970 or two 6990. This is why I got three 7970. biggrin.gif
