Problem with X1950XT X

[GFX707]

Just got my Powercolor x1950 XT Extreme and was pleased to see it had an Arctic Cooling cooler installed....however since installing it I have gone from random resets every 10 minutes and glitches in games to random resets every 10 minutes with the card suddenly thinking it's 500mhz instead of the 650mhz it's supposed to be.

It replaced an nVidia 6800gs which I removed the drivers for (using the control panel uninstall) before installing the ATI, and then installed the drivers off the CD and immediately replaced them with the latest catalysts....the newest cats give me glitches and the older drivers make the card seem to slow to 500mhz, and both are giving me frequent system resets.

Can you guys help with any suggestions? Thanks.

edit - I notice something about "power states" - is this some new feature of newer ATI cards which clock themselves down when idle or something?

I have a Tagan 470w PSU.

Last time I used Driver Cleaner it seriously messed my system up....you think not using it to uninstall was the problem?

Why the wink? Did I just buy a fraudulous card or something?

This has been around since at least the X800 series of cards. I had a few. ATI uses lower 2D Clocks and then ramps-up to Full-speed when using 3D. The only way around this sis to use a second party overclocking app or Overdrive in Catalyst Control Center.

OK - had an nVidia for a year or so, out of the ATI loop

OK, will do that. Screen just froze when I was randomly browsing internet.

I was trying to find your Tagan PSU online and I couldn't find the 470w model, do you know what the model # is?

Errrr, it's 480w, sorry....TG480-U01.

Hmmm, just clocked my computer to its normal speed (getting rid of my pitiful 20% conroe overclock) and the flickering etc. seems to have gone.

 

[GFX707]

Well, I am not surprised....crappish board really, asrock 775 DUAL VSTA.

 

[GFX707]

OK, I ran driver cleaner, etc. and now instead of crashing the entire computer and locking up at random moments it's crashing in most games with various error codes (All of them have 0xc0000005 in the technical details part).

Any ideas?

One more thing, I switched from an AGP card to a PCI-E card on the same board with dual connectors. Would that in itself cause problems?

The problem seems to be fixed now - a word of warning to everyone about ATI tray tools....be sure to check the fan settings before you run anything the first time with ATT installed....the settings are a bit "liberal" so you'd better check those yourself or you could get some high temps.
