How to overclock a 7850 past 1050MHz?

I got a confirmation email saying mine wil arrive between 1.30 and 2.30.

Shame I'm at work and will have to wait until I go home to try it.

Lucky you have someone at home to pick it up. When I know I'm getting a DPD delivery I have to keep checking which hour it'll be delivered so that I can skulk off home from work to "work from home" for a little while :D

I do notice the difference using MSAA. I mean, it ain't huge by any means but definitely noticeable. Also my 680 can hold 60 FPS with it on 95% of the time. Anyway, all I meant was that the FPS numbers need to be considered against other benchmarks on the web which run generally with MSAA on and at 4x.

I wasn't trying to talk down the performance you're getting or anything - it is very impressive.

No worries dude, I just benched at the settings I would use. In order to maintain what I call good fps at 1920x1200 on Ultra, this card has to choose between either 2xMSAA or FXAA=high. For me, FXAA set to high gives better results. 8xMSAA would be nice, but the hit is too much for a sub £300 card. Benching with FXAA seemed more practical because that is what most people will end up using for these cards.

4xMSAA pulled the 1200MHz card down to 40-50fps, and 8xMSAA dropped it into the 30's. FXAA is a much better compromise.

Agree absolutely.
 
I wouldn't return it, a 1150 on the core is still damn good, still over a 33% boost.
 
Haha give me chance!

Still trying to get Starcraft 2 smooth with the new card. Bit jerky when I scroll across the map!?! Anyone know optimum settings for this card and SC2?
 
Still getting frame rate drops. Hmmm this card should be at least equal too my 570 nay better, what going on here. I got rid of all nvidia drivers. Wonder if I need to reinstall windows?

What games and benches do you see drops in? Also, what clocks and volts are you running? My 7850 showed similar dips when I gave it too much voltage. Perhaps over-volatage protection is cutting in, or maybe you have clocked it too far?

If none or the above, try the following:-

i). Download DriverSweeper
ii). Uninstall any AMD/NVidia drivers.
iii). Reboot into Windows Safe mode
iv). Run DriverSweeper from within Safe mode. Allow it to clean all of the AMD and NVidia files it locates.
v). Reboot and install the latest official AMD drivers.

does oc graphics card really make much diff in real life?

Yep. It can make the difference between smooth and juddery gameplay, or allow you to enable extra graphics detail.

The average fps of the stock clocked 7850 above are equal to the minimun fps given by the 1200MHz overclocked 7850.

edit: The above overclock makes the 7850 about as fast as a stock 7950. ~£330 worth of performance for ~£180 is better value than £180 for £180.

Yes. It takes the 7850 from a merely 'good' mid range card, to an 'outstanding' card with some of the best price/performance you can get.

The OC directly translates into tangible game performance improvements, especially in more modern titles that really give your GPU a workout.

As you can see from 555's graph above, at stock the 7850 can dip down to even sub 40fps, which is not what you want at all... with a good OC the card rarely dips below the golden 60fps.

So far only Starcraft 2. ALso moved the sliders over in ccc and Starcraft 2 crashed. WIll try driver sweeper

Had it delivered to work instead as no one home.

Got it sitting on my desk as we speak. I'm tempted to open it now for the sake of it + the haribo.
