That worked fine all the way through although towards the end the fan kicked up to 100% a couple of times.

How to overclock a 7850 past 1050MHz?

Loving this card so far. ASUS HD7850-DC20-2GD5.
Gets to around 65c in Heaven @ 45% fan speed which audible but not intrusive. Now to test real games for stability.
Excellent OC. I was going to say how did you get that high in Heaven, then I noticed you don't have 4xAA or tesselation on. Gave me a scare then
Those hitting 100% fan and 90C+ when OC'ing... which cards are you on? Even at 1.225V I've never seen my card go over 72C :|

If it didn't crash then that would point to insuffcient cooling , and your chip, like mine, needs loadsa volts. If it completed all the benchie without crashing, you could try keeping the 1150 clockspeed, and dropthe Vcore by small increments, but keep the fan at 50%. If it works fine, try going a bit lower with the volts until it crashes.
Post back with the results.

Aha! I wondered why the score suddenly jumped. I guess the settings reset without me noticing
. I'll re-run.

I'm really tempted to reseat the cooler om 7850, theres a hell of a difference in temps here, I've actually seen 97c (yep, 97c) after a run at 1.220V and I don't think the coolers are that bad. Saying that, I've seen a very nice cooler thats being released for the 7850/7870 cards, a "Gelid icy vision rev 2" in about two weeks and I haven't had a play around doing this for along time now and I fancy having go again.

i scored 959 points with stock 5870,still waiting for 7850 prices to drop abit more

That cooler is already out:
http://www.overclockers.co.uk/showproduct.php?prodid=HS-002-GD
It's a very good cooler and would cool a 7850 easily.
Would make your VTX card about as expensive as the MSI, so not too bad.

Now I looked at that one earlier and on ocuk page it doesn't have compatibility for the 7850/7870 cards, but on the site I looked at, it says it does
I'll do a bit of digging and see if I confirm either way

The 78XX's weren't out when that cooler came out, so they prolly added in compatibility to the website after they released and could check they fit.
Soldato
Ooooo....tempted
Edit: Just checked Gelid solutions own website and these do indeed have 7850/7879 compatibility. Just got to try and justify the cost, and will it enable me to clock higher?
Decisions, decisions

I'm in the same boat here. I'm going to try driver sweeper either later or tomorrow. I had NVIDIA drivers on before, so I'm wondering if something weird is going on there.
Soldato
It might be the version of teak tool you're using. Check to see its 2.0.8.3

I have tried both of the most recent versions and both of them against the 12.3 and 12.4b drivers, with and without CCC installed.

I assume you've done the following:
Installed either 12.3 or 12.4 (I don't think it matters which one really) reboot.
installed Asus tweak 2.0.8.3. reboot
select "advance mode" by selecting the middle button of the three small vertically buttons placed at the bottom lefthand side of the tool window.
select "settings" from the four larger options above these three little buttons.
From the window that opens, select "tuning" from the five options running across the top of this pane.
Towards the bottom of the pane, there'll be an unticked option called "overclocking range enhancement", select this option by putting a tick in it's box,
While you're in there, towards the top of the pane you're in, theres atick option to enable "GPU voltage", put a tick in the box to enable this option.
Onve you've done all that, select apply.
the screen will flicker and go black for a few seconds, then appear normally.
Select "Tuning" from the top of the line of options running vertically on the lefthand side of the pane and ....voila, you should have the increased overclocking range available to you.
Hope this helps, I can't put anymore comprehensively

when you say
"While you're in there, towards the top of the pane you're in, theres atick option to enable "GPU voltage", put a tick in the box to enable this option."
do you mean in the display priority bit? or is there another one saying something like this that i'm missing?
if so then unfortunately, yep, done all that. Only thing that's different is at the end when you go back to look at the sliders they haven't changed : (
oh well, going to uninstall everything, run driversweeper in safe mode, then try again in exactly that order. cheers

Yes mate, the "gpu voltage" option is in the same area as the "enable overclocking enhancement" option, its higher up, thats all.
had another go, didn't work again, tried to system restore back to before installing gputweak for the first time, didn't work again.
so your gputweak settings pages just look like this?

is there any part of the gpu-z part that looks off?
i'm starting to wonder if it's something to do with my card. do other people who have the sapphire version have the non-oc version or the oc version? is there anything i need to unlock on the card to let me do something? i don't know anything about these things really.

very very similar information in gpu-z to this guy, but he has a pixel fillrate and a texture fillrate over 0. is that relevant?
frustrating... think i'll go to bed and try again one last time tomorrow
