How to overclock a 7850 past 1050MHz?

Heaven usually just kicks me out with a driver failure if I've gone to high, same for BF3.

1225 is my limit for 1.15V by the way, 1250 failed.

Looks like you and 555 have some good chips, mine doesn't seem to want to do anything consistent as you can run it once and its fine and same settings again a bit later and doesn't like it.
 
anyone who overclocks their cards needs to watch the heaven benchmark and not just set and forget.

I can run higher core and memory, and whilst heaven will come back with my score I know it's not stable as I've seen a few tale tail signs of graphics corruption. Very quick, but there none the less. I'm 1150 stable and happy with that.

I take it you've encountered no issues with the TF3? Read somewhere that there were some issues with TF3, cant remember what or where it was from though.

Interested in getting a 7850 soon, well depending on stock and price but cant decide between Sapphire and MSI.
 
Well i'm settling at 1100 core and 5800 memory at 1125 voltage for tonight.

GPU really doesn't like going over 1100 on the core without some significant instability. Might try some different drivers tomorrow though and see if I get any more success.

Absolutely none. It's been flawless, one of the best cards I've ever owned.

Just come out of a BF3 session @ 1225MHz 1.15V, 63C and 45% fan, solid as a rock. :cool:

I've had this card OC'd since launch (at various settings) and it's given me no problems at all.
 
Right, Starcraft 2 seems ok-ish. Need to have a play but bumping core to 1000 has helped A LOT! Haven't touched the memory, might inch it up a bit in the morning. Still wish it wouldn't suggets that I should be running with medium settings but hopeful this is a driver issue.

Initial jitters aside I like the card. Fairly quiet and powers down nicely. Starting to feel happier now!

My drawback is that i'm running at 2560x1440 which means the GPU will always be stressed on BF3 with ultra settings. I may just put the money up for a second card and run them at lower speeds to get the performance.

So tempted by one of these - problem is that i'd be coming from a GTX570, so it'd need to be a good clocker.

Fair point. I have just done this and the biggest instability I have found is starcraft 2. Though I believe this is a driver issue not the card. I think the card will clock happily enough using the guides on the first page. Drivers for the 570 are reasonably mature in contrast.

But having said that these are quiet, run cooler and use half the power
 
Okay, I haven't got the Overclocking range enhancement option on a VTX3D HD7850 when using the 2.0.6.0 version of Asus Tweak tool. The most recent version does have it, however, I still can't go over 1050. I'm locked there. I did have CCC installed, but I have freshly uninstalled the drivers and reinstalled them, just the driver, and the obligatory catalyst unistaller.
 
I've been watching GPU tweak monitoring software and my GPU keeps switching to 3D mode when just sat on the internet although GPU usage is 0%. Anyone else seen this as its causing me to have higher temps and making what I consider to be a loud gfx card even louder.

Also what temps are people getting. Mine is sitting at 55-58 idle which just seems stupidly hot when its not doing anything and load its up over 80 and thats with the fan at high speeds.


EDIT - I've just checked a bunch of review sites and they all showing idle temps 20-30. I think I've a got a doozey of a card as ambient temps aren't to high and I've got a very well ventilated case.

I should be buying a new gfx card in the coming week or so. I was set on a 7850 at a sensible <£200 price mark but I've now got some extra money to play with and am being tempted towards a 7870. This is despite the consensus of opinion and logic saying I should get the 7850. I even had my finger hovering over the 'buy' button for a Sapphire 7870 OC GHz for £260 earlier today...

Are there any decent comparisons of a fully clocked 7850 v 7870?

It's a bug with Firefox. If you use IE you'll find it doesn't happen.

For some reason in firefox when you scroll it makes the GPU ramp up to full speed.

Power isn't a massive problem, nor is noise or heat as the GTX570 is just fine. What i'm not happy with is being bent over regarding HD7870/7950/7970 and GTX680 pricing, which is just a big urine extraction.

Especially if I get one of these at around 1200MHz+.
