Ars Technica heeft een review van de Asus K7M neer gelegd. Hoewel Ars over het algemeen tevreden is met de kwaliteit van het bord, lijkt er wel een probleem te zijn met de TNT2 Ultra kaarten. De oorzaak blijkt (alweer) te liggen in een power probleem:
Although our test bed for this round-up used a non-Ultra TNT2 card, I decided to throw an Ultra into the FIC and into the K7M to see if I could verify any of the reports I had heard regarding the K7M's Ultra support. Having none on hand, I busted out and acquired a Guillemot Xentor 32. To keep it short 'n sweet, the rumors are true. The Xentor 32 (which is an Ultra-class card) would consistently lock up the machine when running at it's stock speed. I could get it to run reliably by clocking it down to 150/175 (from the 175/183 it comes at), but what the...? I tried the same card in the FIC board, and I was able to get the Guillemot card up and running on the FIC board all day long with no problems.
Now this is a very interesting turn of events. See, originally FIC was being ripped on because of its finicky power supply support, but now we see that the FIC is, when supported properly, capable of supporting Ultra TNT2 cards. The irony here is that the Ultra card is almost certaily failing because it can't get enough power. The Ultra consumes considerably more power than the standard TNT2, and when you combine that with the power-thirsty Athlon, you've got a serious power strain on your hands. There's a reason why AMD recommends certain power supplies!
