Hi, everyone. Sorry for long post, but I need help and can't express myself in fewer words. :o) I just bought a wonderful new video card for my wife's 'pooter, installed it, and it screams very loudly when power is turned on. Fans also do not rotate. I called manufactuer and they ran me through a few BIOS tests and determined that the voltage at the AGP slot is too high. V-Core Voltage = 1.76 volts and they said it can't be above 1.6v. I also swapped out the 600W powersupply and that made no difference. Put the card into another pooter with a much smaller powersupply (300W) and it did not scream. So... looks as if the MB in her 'pooter is dying. Anyway.... I am thinking of replacing the ASUS board with a Tyan since that seems to get good recommendations. Can you folks recommend a specific model Tyan? I am NOT technically inclined, so I really need guidance. Wife would like to investigate the possibilities of an AMD 64 processor so please consider that as part of the recommendation. She currently has an AMD 32 (1.7+ which I think is equivalent to 1.4 Ghz). Also, wife wants to know if it's possible later to pull the AMD 64 and replace it with a dual core AMD processor. Basically she doesn't want to have to replace the MB again for awhile. Alternatively she is thinking about 4X32 AMD processors. Is that insane or is that within the realm of rational thought? She realizes that there is not much in the way of 64 bit software at the moment so we're trying to plan for the future. We'd like to get the most bang for the dollar yet we can't be extravagant. Still, we also don't want something temporary. Your help with as much specific information will really help my shopping for the best price. Thanks, everyone. :o) Gil

The wattage of your power supply has nothing to do with the voltage on the bus. Some BIOS-s have adjustments for voltage. This is for those who like to "overclock" their computers. Higher clock rates usually require higher voltages. Perhaps you can boot into your BIOS and find a voltage adjustment.

There does not appear to be a way to adjust the voltage. The tech support folks at the company that makes the video card seemed to think that there was too much voltage at the AGP slot. Perhaps this is what caused the previous video card to fail and is causing the new card to scream. The video card tech folks said the card is designed to make that noise if the voltage is incorrect.

Hmmm-- too bad. One last thing to try. If there is an adjustment for clock speed cutting that back just might also have the unadvertised side-effect of cutting back on the voltage.

So, if there was any doubt, that confirms that voltage really is the problem. If the above doesn't work you now have a great excuse for getting a shiny new computer!

/snip/ There are apparently _two_ standard voltages for video cards. I also bought one of the "wrong" ones, and my ASUS m/b was smart enough to detect the problem, and would not run, the fans wouldn't go, etc. This was apparently the case also when I tried to plug this card into my grand-daughter's m/b. I can't imagine why the computer industry allowed this to happen, but it has. You have to look at the specs for your m/b, and then make sure your video card will work at that voltage, and if it's not obvious, you'll have to contact the video card manufacturer and find out. --doug -- No virus found in this outgoing message.

Yes, I thought it would be oh, so simple. Just plug it in and go! NOT! :o)

Oh, man that that's getting in WAY over my head! I pulled the MB and replaced a heat sink a few weeks ago and I thought I was really getting adventurous! :o)

And thus the reason for my post this evening asking for specific recommendations of Tyan boards and AMD processors. :o) Thanks! Gil

I don't know about 4xAthlonMP, although Tyan makes some very good dual boards, and MSI makes very good dual Athlon workstation board which come in at a reasonable price too. As far as Athlon64 goes, I would definitely recommend Gigabyte - they have dual-core capable boards. If you're serious about performance in the future and you're willing to spend some money, why not go for a dual core capable dual Opteron board, with a single core CPU (just one) for now until dual core prices are decent and you can afford to slip two of those hotties in?
