X1900XT - Card Clocks Problem

Recently had a go at overclocking my X1900XT PCI-E as I've had it for a while and wanted to see how far it could be pushed on stock cooling. The max I could get it to was about 695 on the core with ATI Tool, couldn't get the memory to go past 750 without artifacts. Pathetic, considering the OC's I've seen other people manage, but I put it down to the card being oldish. Since then have played Crysis for multiple hours without any hitches, until yesterday, when loading my OC clocks caused a system hang.

I had to reduce the core clock to 685, then 675, and now just loading regular 3D clocks (even though ATI Tool is forcing 621/747 for some reason) is causing a hang in Bioshock. I've re-enabled the ATI Hot Poller Key and it seems to be O.K., but I just wanted to know if I've screwed the card beyond OC'ing capability. For some reason Bioshock just doesn't seem to look as good as it did before I tried overclocking, but that might be thanks to playing Crysis :p.

Thanks in advance!
 
I'm running 688/774 (in ATI CCC) Accelero S1. Doesn't go above 50. 33 idle. 12cm fan @ 7v. Compared to the stock cooler, it's still quieter than the ATI cooler at idle, and cools better.
 
I was thinking about going for a better cooler, although I still have some doubts. First of all, my card was getting to about 75 max in Crysis on High settings with aforementioned OC'd clocks; this didn't bother me that much because of how old the card is. Plus, with the problems I'm getting, will a better cooler allow me start OC'ing again, or have I bust the threshold of the card itself?
 
I've actually already re-seated the heatsink, but with Antec Formula 5 Compound, and attacked the card with a can of air. Funnily enough I was using ATI Tray Tools until I decided to have a proper go at OC'ing. Thanks for the guide and I'll be sure to use it.

Guess you can't go wrong for £11! Cheers chaps.
 
Right, last post in this thread I promise. I've been using Concorde's guide to start OC'ing again. An Accelero S1 is on its way in the post (although it cost £24 inc. P+P from Overclockers). The problem is, after setting 2D clocks and voltages, I can't set the core voltage for 3D clocks BACK to 1.45. I click apply and it switches back to 1.2. Memory isn't a problem as I can set that back to 2.0888/2.0888. I've tried searching the net for an answer on this but can't really find one. Any ideas?

Thanks again!
