Hmm well my BBATi 9800 Pro seems to be a very expensive paperweight. I put a new HSF on it last night, and this morning i installed it. It seemed to be working fine but i didnt have time to mess with it cuz i had to work, i just let the computer fold while i was working. Got home, fired up 3d01 at 420/365, and got massive artifacts. This was strange because i could run at that speed when the card was stock. So i restarted, tried again at stock speeds of 378/337.5 and still got artifacts. So i turned the memory clock down to the minimum, like 303mhz and got no artifacts. i then turned the core clock up to 430 and got no artifacts. I put the stock HSF back on and the same thing. evidently there is something wrong with memory on my card, because if i turn it up past like 320mhz i get artifacts... i wonder why this happened? i checked over the card very carefully and could see nothing that would cause this. there was no thermal compound anywhere, no bent capacitors, nothing. I tried reseating it and still nothing. Right now im using a GF2 mx200 If i cant figure this out, im not sure what im going to do really. I would just get a 9800 Pro, but the RV420 is coming out in a bit. But i cant wait that long without a card. so who knows. I guess we have all broken stuff, it happens when you mod a lot, comes with the territory. it just doesnt make sense though that its the memory. enough of my rant.
