Waiting for my Sapphire 7950..will joining you guys for great OC

Received my Sapphire 7950 last Saturday, but unfortunately it's not a dual fan version as promise.
So I return the GC and now still waiting my Dual fan OC version to arrive.
But anyhow, I think worth additional RM60 for a dual fan, cos I don't want heat issue to stop my overclocking result

From all the review, I should say I don't like the reference noise.
Beside, the heatsink also different
I wonder what's the different between this two in terms of material and overclockbility

I don't care much about noise, what I can hear is from my speakers. (I always play games in hi volume)

Got my Sapphire HD 7950 OC today, here's some benchmark compare to my previous HD6870

(from left to right)1=6870ref, 2=6870@980mhz, 3=7950ref(900mhz), 4=7950ref(900mhz) Max setting

Ya, I think so..currently working on stable OC (1Ghz/6Ghz +20%power ctrl)
Not dare to try TriXXX to increase voltage, but I'm happy with what I've achieve

Update OC result for Furmark 1080p benchmark
900mhz/1250mhz = 2325 (57c)
1Ghz/1500mhz = 3267 (63c)

Increase about 25% (but I only increase 10% frequency, how come? )

Added on October 2, 2012, 11:25 pmI have a question, hopefully sifu(s) here can answer.
In CCC overdrive, power control.

7950 is a 160W TDP card, by increasing toward 20% setting means allowing 200W TDP for the GC.
Question: Does this means the GC are always working on 200W? Or the 20% means the extra voltage given only when the card need it?

Thanks in advance

3dmark11 = P7960


Finally Achieve HD 7970 reference (at least in 3dmark11)
Unable to Run in game benchmark, no idea why..

Now looking forward for higher level

Currently benched with 3dmark11, 3dmark Vantage, Heaven 3.0, Furmark, Batman: arkham (Can't get this right, as ref higher than OC)
I believe the improvement from 6870 to 7950 is close to 100%

You can download lots of benchmark from here FREE

No worries. Please share some benchmark once you have the result

Yesterday I try to Run Splinter Cell Conviction
And switch on SSAA (which i believe only AMD offering this Anti-Aliasing) in 4X
The graphic is phenomenal, even the leaf and many background detail is anti-aliased. However, this take a huge punch on performance, give it a try

Nice
Why don't you try some extreme setting? Your card deserve for a Max test

Impressive
May I know your CPU & GPU frequency?

Thanks, how about CPU? did you OC your CPU?

LOL, It's a waste if you didn't OC a K processor.
Mine working at 4.5Ghz, with stock coller you can achieve 4Ghz no doubt
Higher clock will mininize the bottle neck of your GPU, you should try

I'm using Xigmatek S1283W, 4.5Ghz Run prime95 around 60c
I always keep my eye on the temperature, make sure it doesn't exceed 75c

For i5 2500K OC guide visit, lots of sifu there can help you out, I learn a lot from there

No worries
However it's good for you to track the record before and after OC your CPU.
Feel free to share some if you can achieve higher score
Good luck bro

No problem, as long as you monitoring the GC temperature.

So fast received your 7970? how much you bought?

Added on October 4, 2012, 7:49 pmI can only achieve 1093 point with 1000mhz/6000mhz OC
But temperature around 50c+, now have to push some limit

I'm working on what's the Max clock I can go within 80C
Cos current Max is about 60C, So I think still a lot of room for me to OC

Wow!! that's impressive !!
How much voltage you increase?
