Overclock gone wrong... help!

thecremeegg · 7 May 2010 at 17:28

Right I tried to increase the overclock on my 4870 but it failed and I got massive screen corruption and then grey, requiring a reboot.
The problem is that now if I load into windows I can't get into CCC without the same corruption! I can't work out how to stop it as in safe mode CCC won't load!

Any ideas?

Have you tried un-installing driver/ccc then re-installing?

Phoenixdancer · 7 May 2010 at 18:11

Just simply uninstall and reinstall and while your at it get the new 1.4 drivers

thecremeegg · 7 May 2010 at 18:12

Yep, and its still the same, has seemingly saved the oc to the card or something

Tried uninstalling it and deleteing everything from the registry and AppData etc?

thecremeegg · 7 May 2010 at 18:15

I'm in windows now having uninstalled and reinstalled the ATI 10.4s. If I try and load CCC then it all goes wrong and artifacts

Edit: Andy, what do I need to delete from the registry? Cheers

try a driver cleaner program??

Phoenixdancer · 7 May 2010 at 18:22

put the card is a diffrent pci-e slot and change the overclock and then put back in original slot

Your CCC profile will be saved in C:\Users\your name\ Local\ATI\Ace\profiles, if you can get in there then you can edit the clocks manually using notepad. Assuming of course you saved it to a profile.

Should be this

Stop using CCC and use AtiTrayTools, imho it's better. If using Win7 you'll need to disable driver signing, google it, it's dead easy.

Load up safe mode and then remove the drivers/edit the config

do a search for ATI and delete what ever pops up, then just reinstall drivers, that should solve it.

if nothing else works then grab a hammer and give it a good beating.

no do what Devrij said it keeps the profiles saved even if you delete the program, when you reinstall it automatically links it back up hence its ok when it uninstalled...not when you reinstall.

Uninstall CCC then goto C:\Users\your name\ Local\ and delte the ATI folder and all its contents, then reinstall CCC...done

have you got a on board vga port?

Download Driver Sweeper (google), works perfectly.

Can cause problems. I used it with either 1.3 or 1.4 drivers (not sure which) and it meant I couldn;t install CCC again no matter which driver I used to install.

Ended up having to wipe windows 7 and reinstall.

So use with caution.

In the end I used driver sweeper, which on its own didnt sort the problem. I had to download rivatuner and use that to set the clocks back! I must have rebooted over 20 times tonight, not a process I want to repeat!
Thanks for the help guys
