This seems to apply to both the G5 version and the MacPro version.

We have one G5 version we are trying to get exchanged by ATi - which USED to be a straight forward procedure and is now nightmarish ( anyone have a live contact there ??? )


The cards tend to overheat - there is a discussion here

Mac Owners Support Group :: View topic - ATi Radeon X1900 XT: Too Hot for the Mac Pro

Dust built up in particular.

:eek:

Cards in the MacPros are easy to get at so have a look every once in a while - save you some grief as unlike retail cards your warranty on the Apple version is only one year unless you extend it.....

Add this to your maintenance list. $479 for a replacement if it fries out of warranty.

Good idea.

I just took apart the one in the G5 which is a different design.
Nasty as there are 8 small screws to undo to get to the copper cooling and sure enough it was at least 30% restricted with dust build up. :mad:

What a sucky design - all in the name of keeping it to one slot in the G5 version.
Too little cooling and too easy to clog up.

Air cleaning will work but be careful with the compressed cans as they can get reaaaaaallllllly cold and harm the components.
We use a compressor we can dial pressure and no cold factor.

The fan on the G5 version seems to force air INTO the Mac against the fans of the machine as the clog is inside the housing and not visible without removing the cover plate.
I removed one of the pCi Slot covers to improve air flow over the card so the exiting air from the GPU will go right into the air flow above it and not build up.
Might help.

So far no artifacts which given ATi's new found idiocy on exchanges ( thanks AMD :rolleyes: ) will be a real bonus.
My staff spent two hours trying to execute a warranty exchange with no luck at all.

Update - clearly the card is cooked - artifacts still tho it took longer and finally froze the machine.
Oh well at least they won't come back to us about dust.

Still dropping to a 6600 after a 1900 is :( ...slowwwwwwwwwww

Y'know ATi USED to have one of the best warranties in the business. No longer.

A $500 card like the 1900 only carries a 1 year limited warranty. That sucks big time. :mad:
