How to overclock a 7850 past 1050MHz?

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:)

Very comprehensive, but yes, I have done all of that already. I cleared out the last vestiges of the nVIDIA driver and physics stuff but no luck there.

It has to be something in the system config, or the Asus tool settings which is stopping us from getting the unlock to work.

Ahhhhh, I don't know how to change it, however, I get an offset: (nnn) above the adjusters which isn't in anyone else's images who have successfully unlocked their frequencies.

Edit: that doesn't seem to matter, see next post

Those are stable for me on the Sapphire HD 7850 OC
Kinda sad about those voltages. Couldn't go 1200 core on 1.180 to 1.200
Didn't want to up

EDIT: oops, forgot the rest of the benchmark info:

Those settings are virtually what I've got and I'm currently running at. Shame I can't hit 1200 core for 24/7 use but takes a load of voltage to do so and of course the fan has to be run at 100% which is deffo a no go for me. I've got my gpu voltage at 1.2v, temps are really good so I might see if I can run stable somewhere between 1150-1200, maybe 1175?

It appears to me theres a lot these chips that need higher voltage to even run stable at 1150 core so I don't think theres a heat issue here after all, they just need loadsa volts unfortunately. I might be wrong though
 
Yep, it could even be reaching stock 7950 levels from what other people have been saying.

two00lbwaster, any joy? I uninstalled GPUTweak, registry cleared it with Ccleaner, uninstalled all AMD things, did driversweeper and Ccleaner registry clean again. Then I reinstalled everything one by one, rebooting along the way.

AND IT STILL DIDN'T WORK : (

I've just noticed that the option called " Keeps setting for next start on close application" is unchecked. I've got that option ticked, long shot, but bung a tick in the box and see what happens

Exactly the same as you, and I may have issues with maximum CCC values on stock volts.

I cleaned up using the cleaner, and then I manually went through the registry looking for nvidia values. Found a lot of them. I still have two PCI device entries for GTX 260s that were my previous cards.

I'll be buggered if I can be bothered to wipe my machine to test out whether it's an issue with my current installation.

lol, yeah, I have that ticked now, I just hadn't had it ticked when I freshly installed the tool. It makes no difference for me, still stuck at 1050 core.
 
made an account just to say i hate u guys...u made me fork over £181 to get this gpu after this thread...

will OC to 1200 the moment i get it! Getting the Sapphire 7850 (not OC edition)...so will see how much headroom that one has.

Would be an upgrade from my good ol gtx 260... R.I.P lil one
 
Really is odd how ASUS tweak isn't unlocking some peoples cards... just doesn't make any sense... we're all using same drivers and software... :S

We need MSI AB and Sapphire Trixx to get updated to give people other options for unlocking.
 
I get the feeling there's just some .dll sitting somewhere that hasn't been cleared and isn't picked up by CCleaner which for some reason isn't removed or edited right.

Very frustrating.

Tiny part of me is tempted to do a full format of my SSD and a reinstall of everything, but I feel a bit uncomfortable still writing and rewriting to my SSD hah, maybe I'm living in the past.

Flashing the bios of the graphics card - I've seen this phrase a few times, what does it actually mean and could it possibly work?
 
Flashing is replacing the cards bios with a another, usually a modded one to allow greater overclocking headroom, unlocking extra shaders, but can also come from a higher spec card (7870 'frinstance) to enable the higher specs cards options on the lower spec card.:)
