HD 5750 flickering when any core speed changed?

[mcgge1360]

The bottom part of my 2nd and 3rd screens will flicker and move a bit if I change the OC settings on my 5750. This isn't a voltage/power issue because this happens with +1 mhz, +5 mhz, +150 mhz, and even underclocking. At it's default speeds it performs fine. I really would like to OC this card because it's not very powerful and until I get a new card it's all I have. It is a passive heat sink version so there are no fans, just a very large heat sink, and one of my fans blows directly onto it. At 100% it sets at 49 degrees, +100 mhz is 52 degrees, and +150 mhz is 56 degrees. The screen flickering happens on both AMD catyllist and MSI afterburner

it is the 1GB ddr5 version if wondering.

Why would you OC a video card with no cooling? You should remove the 2nd and 3rd screen as well if you are using it for gaming. It is not a gaming card, if you are using it as such with 3 screens, well, I wouldnt. If you arent using it for gaming, it should be fine. Those cards arent made to be OC'd.

I said it has no fan, no that it doesn't have cooling. it has a large heat sink which radiates heat instead of a smaller one with a fan.

Ok, I read that. I will repeat the question. It doesnt have any capability on its own to cool itself. It is dependent on air flow in your case. It has no cooling of its own. Why would you OC a card like this? It isnt wise is my point.

My case fans always run at the same speed, so the airflow stays the same, or goes up with my processor, but never down.
