9600XT Corruption

[Jules]

Hi

I am hoping someone can help - I have a Gigabyte Radeon 9600XT (128)
which works fine, plays games fine no problems, BUT, as soon as I turn
on overdrive or try to overclock it, even by 1mHz it either corrupts
the screen producing unreadable fonts and icons disintergrate etc...
OR XP hangs. (I have a feeling this might be the difference between
when I have VPU recover on or off)

Now I know this is not a show stopper - but it is kinda of annoying
that most people seem to enjoy at least SOME overclocking.

I initially installed the Gigabyte drivers - tried uninstalling them
and using ATI Cat 4.8 - same. Tried disabling fastwrites, pegging to
AGP 4x etc... It could be heat related, but 1mHz!!!

Of course by default it runs 499.5 GPU core and 297 mem (ATiTool info)

I am not sure if there is voltage control over the AGP in the BIOS
(never normally bother with GPU o'cing) but I dont know what voltage
requirements the card has anyway????

I would be really happy to know what the problem is.

Jules.

Make sure your fans are clean, and working. If you can relocate your other
cards, to give the video card more room, that may help also.

That's odd, a 1Mhz core overclock from stock should not do anything. It
means your card is riding on the ragged edge even at stock settings.
Friend's 9600XT will take a 100Mhz core overclock on the stock cooler, and
his memory will take 25Mhz. I would suspect that the factory application of
thermal compound is either incomplete or flawed in some way. I'd remove the
hs/f assembly and reapply with thermal glue or better yet replace it with an
Arctic Cooling VGA silencer.

All cards can overclock by at least 1 mhz.
If you can't, then there is some issue with either the card BIOS, or
your motherboard, installed hardware, or installed software
interfering.

What is probably happening is, the clock set request is failing, and
trashing the display, or, actually setting it 100 mhz faster (or much
more) or so, when you only want 1 mhz.

I have no idea how to fix this type of problem.

The card is fairly new (1 month)and the fan is working OK. The only
other card is a PCI WiFi which is in slot 5.

I have run the same tests on the card at the default frequencies and
the card reaches the same temperature - but does not corrupt.

Could there be any software/firmaware issues to cause this, or are
these symptons exclusive to hardware?

Thanks

try turning off write combine or something like that and also fast write..

yeah, I had already tries turnng off fastwrites. I dont know what you
mean by write combine????
