Artefacts with Radeon 9800 on IS7-G

[dp004i]

I've started getting artefacts with my Radeon 9800 Pro (Abit IS7 mobo) after I swapped an Intel 2.4B (133FSB) for 2.4C (200FSB) if I overclock the FSB to anything over 225MHz. The processor runs prime95 for hours with no problems at up to 250MHz FSB on this mobo, so I don't think it's causing the problem. AGP and PCI frequencies are locked to 66MHZ and 33MHz, repectively. I'm starting to suspect that the prboblem is with the motherboard, but not quite sure yet. Are there any settings I can play around with that might solve the problem?

PS: The artefacts look like those you get when your video card memory is overclocked too high (borken lines and polygons). My card is not overclocked.

You're not the only one with problems,I just had to RMA my 2nd 9800 pro on a Abit IC7,looks like these boards are killing Radeon 9800's.

I took my board to get look checked out by the store & will know for sure on Monday.

But it looks like the abit is the culprit,when I bought this board It killed my 9800,I figured it was a fluke & RMA the video card.

I was using a 8500 in the meantime while I waited for my 9800 to come back,today I got a new 9800 back & installed it.

Guess what... artifacts all over the place like when you OC the ram too far... killed an other one. :disgust:

The second i get my IC7 back it's getting sold !!!

I don't think it's damaging the card - it works fine if I bump the FSB down a bit.
