Initial slight artifacting which quickly goes away?

Learning OC novice here with with a query just to be safe. I'm using a brand new MSI 7850 Power Edition OC 2GB and after raising my Core Clock with Afterburner to just 1050mhz (from the stock 950) and running Kombuster I get some slight artifacting upon immediate running of the test which then seems to fade away after a couple of seconds and it appears to continue just fine and clean as I let it run. Is this normal? To have initial artifacts as the test begins?

My temp raises to between 55-59 degrees - well below the threshold, as I understand it. I also raised the Memory Clock up from 1200 to 1250mhz and the artifacting was indeed slightly more pronounced, at first, but again it seems to fade away after a couple of seconds, completely. It almost seems like it's just caused by Kombuster's own initialisation process before settling down, nothing more. Am I wrong?

Edit: I've just noticed it's literally three distinct flashes of artifacting in as many seconds before it completely ceases and the test continues as normal.

I'm so far only using the default Afterburner settings and I've not yet utilised the unofficial overclocking method.

Thanks for any feedback!

Hi CaptQuint,
Are you try the improve Power Limit function?
It can raise you to maintain the frequency.
Thanks

pretty common to get some corrupted flicker when applying clocks on amd cards .... ignore it
my 5750 displays a nice checkerboard/squiggly line when applying clocks

This was my problem, thank you! The power bar was defaulted to 0%.

I've since unlocked the unofficial method and so far gotten a stable 1120 core. Anything higher makes Crysis 2 freeze after about ten minutes of play. I'm wondering if it's partly due to my using the latest amd driver instead of an older, more stable and overclock-friendly one. Any recommendations?
