OC'd 9500 Pro overheating

I have a OCSysyem OC'd 9500 Pro (I think they use OEM Sapphire cards) which I have always had overheating problems with... I think.

It came with some generic tin ramsinks and a Thermaltake Crystal Orb fan.

I then switched to a Zalman ZM90A-HP which worked a little better, but unfortunately it didn't really fit in my Shuttle SN41G2 case. Or with the tin ramsinks. So I went back to the Crystal Orb, and got some OCZ copper ramsinks. But I believe its still overheating.

The reason I think its overheating is that if I play a game it starts to get artifacts after a while and eventually the system will lock. The prime candidate for this is Homeworld 2. I can play for about an hour then magically parts of the ships start to disappear and other strange things happen.

I have messed with the core/ram frequencies with Rage3D Tweak, and the card came at 344 Core/324 Memory, and I can bring it down to 308/290 and it still exhibits the same problems.

Any ideas on how to fix this? I would try some other heatsink for the GPU but I would really like to be able to put the case on the cube. Currently the card with the Crystal Orb just barely fits in there.

try the factory stocks speeds 275/275 if it still hapens your card could be toast/damaged

Its just your memory that cant cope with your OC! Try decreasing it to say, just around 280-300 mark, and then it should work OK! I think your core will handle 330+ easy!

I can't seem to get Rage3D Tweak to go any lower than 290 for the memory, and I tried powerstrip but that screwed everything up. Any other ideas?

how are u over clocking? disable you over clock and use something like radclocker or somthing that shows your clock speeds as they are

Thanks for the heads up about radclocker. I was able to turn the card down to stock 275/275 and it seems to be fine. Also to answer your question the cards bios is set default to 344/324 maybe ill start inching it up from stock now. Thanks again!
