Hi all, not long a go i bought the 5850 in my sig that replaced my GTX 480 which sadly died, it was a ebay job to close the gap until a better card is bought.
Now, i have had all sorts of odd things go on with my games with this card, and today, i was Streaming on Twitch.TV, and 2 times my drivers crashed which created a very slow system, so i ended up rebooting.

Now here is the thing, in Far Cry 3, i had horrendous stuttering, in certain other games it struggled with what i thought would be easy, like Crysis 2 on lowest settings at 1080p, but only doing 45-60ish FPS.

So, i looked a lot deeper than i normally would into the Radeon 5000 series, and found that they use error correction on the memory, now i did not go any further than that, i just instantly thought, maybe my OC is causing this?

So i reset the clocks, and i looked up what reviewers were OC'ing to with my card, now there is some huge differences, 1 got 950mhz GPU core, which is an impressive OC, another got 900, and another 875.
So, ok i pushed the core to 850mhz, ran OCCT, passed, pushed to 870mhz, 1 error was found, i went down to 860mhz, and found my stable core clock, i left memory as it was at 1050.

Playing the games i mentioned above are now far smoother, and FPS is far more consistent than before.

The OC i had before was 810 core, and 1100 on the memory.

May seem silly of me writing this up for how old the card is, it just baffled me is all.
