9800 np lock up probs

[tweakmaster420]

ok i have been experimenting with oc'ing the 9800 np and i moded it with amd heatsink... and now that im playing real games not 3d mark... it locks up my pc in every game with the hard drive light solid on and i have to do a hard reset.... i am no longer oc'ing my processor. i am running at stock everything with clean install of win xp.. and now my pc locks up in halo and max payne 2 every so often at different times but it allways does.. i am just oc'ing the card @400/321 and this happens.. could this be im oc'ing the card too much?????? this is really drivin me crazy... these are the only two games i have installed on my pc at the moment cause i did a clean install trying to remedy the same prob in all my other games... if anybody has any info on this i would apreciate it. im runnin 3.8 cats btw.

Uh, yes. Sounds like the core is too high and freezing the comp.

Perhaps. I bet if you flash to Pro you probably won't have anymore problems. Set it back to stock speed just to verify it is your o/c.

And why the heck did you put an AMD heatsink on that thing anyways?

Try going back to the 3.7 cats.
Just from reading other threads, people are saying 3.8's run hotter.

Doesn't make that much sense to me, but it's worth a try.

Lockup is caused by the GPU speed being too high... when the RAM gets too high you get artifacts and tearing before lockups.

I agree with the last two guys. Go back to the Catalyst 3.7 Drivers and keep your 9800 at stock 9800 pro speeds and you should be good. I have a Power Color 9800 SE and have it softmodded with third party cooling, running nice and snug at 9800 Pro speeds. I am creating a little blurb with pics to put onto my website and will let you all know how I make out with the 3dmark testing. On another note My brother bought a Sapphire 9800 SE from NewEgg.com refurbed and it too can run the 9800 Pro speeds with 3rd party cooling.
