Problems OC'ing my 5850

[neokeelo]

I got my 5850 a few days ago running Catalyst 10.2 and 10.3 beta and I have noticed a problem whenever I overclock even a little bit. I am using icronic's guide to overclocking. I was running a 4890 with 9.12 with zero crashes or problems before hand.

original guide -> http://tech.icrontic.com/articles/ov...adeon-hd-5850/

His guide is very good however, When I overclock to even just around 750/1050 I am getting constant driver crash and recoveries in 3d apps like 3dmark Vantage, Furmark, BBC2: Beta, and Batman Arkham Asylum.

Is this probably due to the grey screen crashes I have been reading about or could I just have a bad 5850? I would really like to oc this beast because I have read it can preform at 5870 levels with a little tweaking.

I am running the system in my sig.

Try putting your CPU back on stock speeds and see if the GPU still crashes on OC.
There might be something unstable in your PCI-E clock, Northbridge or whatever.

I put everything back to stock speeds but I still get driver crashes when slightly overclocking, pretty sure its the new drivers or my card. I might try to ebay it and get a different one... I really want to overclock it.
