I think it's 76.8% but not sure, definitely in the 76-78 range though. Not a great OCer but good enough in terms of gameplay, at least with current titles.

How to overclock a 7850 past 1050MHz?

I wouldn't go by asic quality on it's own, I had a VTX 7850 with an asic of over 84% and couldn't get the card over 1150 stable with max voltage allowable in A/B in either benchies or games.

I returned my first card as it had a terrible sag on it, never seen a new GPU card like it. Furthermore it had a ASCI of 72.4% and wouldnt manage much above 1100Mhz. Stock voltage was 1.23V.
Now got a MSI TF3 with an ASCI of 77.8% and stock voltage of 1.138V but yet to run any benchmarks as will probably run it for a few 20hrs or so first.

73% here on my Sapphire, so no major overclocks for me, which is kinda good as i've never OC before. So how would i go around doing it? I just wanna increase it to maybe 1050 or something around that. I've got TriXX so help on that would be useful, thanks. Whats the ideal Mem clock? Newb so help is needed

1100Mhz Core would be achievable I would think and when you consider the reference clock speed is 870Mhz that's still an impressive increase. Bit of testing required. The consensus is to use the Asus GPU Tweak mentioned in a few posts above this (I've personally not used TriXX so can't comment).

Review of Gigabyte card here:

Extra fan? I seem to think they both have two. Also I wouldn't consider default clocks as so easy to overclock yourself.

For £20 more i'd take the 7870.
When I got my 7850 there was £80-90 price difference between the two.

Ok ive download the Asus tool and got it open, what should i do from here?
I registered here to say two things:
1. I want to add to the statistics for how poor the overclocking is the on Sapphire brand version of this card. I always buy Sapphire for their extra cool and quiet cards, so naturally i assumed that the amazing 7850 would be one of the cards able to go as high as 50%. I'm severely disappointed with this card though as i can't overclock it even 10% without a freeze or error of some kind. Sapphire has really screwed the pooch with this card. The most expensive i've ever bought.
2. I think the OP of this thread should put some more effort into the first post. This is the most popular thread on Google for overclocking this card. Some statistics on what brands and models that people have and what clocks they've managed to reach. The OP could thereby show the recommended brands as well as warn people of the **** that is Sapphire!

I have the Sapphire with 1200 core with just 17.6 v. I could not dissagree more with you. Bad luck, just bad luck. It could happen with any other brand.
Cat 12.6 wqhl and 12.7 beta arent working properly with OC (even without it are ****), try 12.4 or early 12.6 beta.
Well this is exactly why we need a table of statistics, because i've read about problems with the Sapphire brand for this card for many other people too. But a few people complaining or raving about a brand is obviously not enough unless we can compare it to other brands somehow. Because you might simply be the lucky one.
I'm on 12.6 beta as i've seen no reason to upgrade. Think i tried some others as well, but it just doesn't work.
I think chances are the same for almost every top brand... really. My ASIC is 84%, what is yours?
Hey guys,
i have the Gigybyte 7850 and i can't get over 1070Mhz, at 1075 Unigine doesnt start, i see only black screen. And when i try to OC memories, even at 1250Mhz i see artifacts.
ASIC is ony 68% and default voltage 1.21 at load.
Is there any way to OC higher this ****?
Max temps at load are 59°C with FAN fixed on 35%..
and sorry for my bad English, hope you understand what i say

84% of what?
ASIC quality: I found Steevo (from techpowerup) explanation very clear.
It represents the arbitrary number Nvidia or ATI assign a die based on its location and performance figure they are trying to target. Just like it was said before a lower number should have higher leakage, but may also mean a closer to the edge die cut. If everything else were equal a number such as 85% should yield a balance between leakage so you can throw more voltage at it and non faulty transistors from die defects. By Steevo
So, more Asic, better GPU=better OC
You can use GPUZ to look at it
