Does motherboard have an effect on oc'ing a video card?

I overclocked my 5770 up to 910 mhz. The stock is 860 mhz. When I'm playing a game such as dragon age or company of heroes the screen goes all weird with bunch of vertical pink and yellow lines it looks like, but when I clock it down to say, 880, it's fine. All over the web I've seen that this card can clock stable to 960 without any additional cooling. My temperatures are very cool even when playing games, I'm just wondering if my motherboard has anything to do with it. Thanks.

It can do, but there are more than just the video card and mobo that factor into it.

You have to remember just because 1 person got 960 core doesn't mean you will, as each chip is different, they may have been on different drivers, and may have had different overclocks on other components. You may have a crap chip that doesn't OC well. To find out for certain, give it a little more power. Use MSI afterburner to overclock instead of CCC, as it lets you change voltage too, but DON'T raise voltages too high, the change will affect heat quite a bit, video cards are sensitive to it. I wouldn't, at first, go over 1.3V (1300mV), if that doesn't get your current OC of 910 stable, there will be something else causing the artifacts.

You can download MSI afterburner from here:

FYI: The 5000 series all use ECC memory so it won't artifact if you clock the memory high. it will either run slower or crash. So only the core will artifact.
 
Why don't you leave the card as it is? Should be working fine and with good fps and graphics with ur rig right? You got a good rig man don't be greedy hahah
