Club ATI 9800 XT artifacts problem

[chris@sweden]

Hello all,

I have already post this on Shuttle mobo section..

My setup produces artifacts even on stock frequencies of the RADEON 411MHz core and 365MHz mem...If I underclock to 408MHz the core, the artifacts are less..

The card is Club ATI 9800xt 256MB

These artifacts appear on metalic surfaces when they reflect light.

ATItool reports 68-70C when idle and up to 79C under load (the maximum I have seen).
For testing I have put a 120mm fan blowing direct on the RADEON dropping to 64C idle and 70C max on load with case open. The artifacts are there even with 411/365 MHz.. So I believe that maybe is not temprature problem of the RADEON...


Also note that this is a second Club ATI RADEON 9800XT with the same problem.

Here is the question

Do you guys think that the on board power supply can not handle the load of the 9800xt and produces spikes ?
Or just the club atis are crappy when you plug them in an nforce2 mobo?

(a friend of mine has the same card on a TYAN dual athlon and he can overclock to 424 with the stock cooling and with no artifacts)

You definately have enough power.... i think your problem may be software. what drivers are you using and have you upgraded to directx 9c yet? does the same thing happen with other videocards in your system? can you borrow one from a friend to see if the same thing happens?
