AGP Bus VDDQ Voltage
According to my Video card manufaturer this voltage should be close to 1.5 volts. My motherboard is apparently delivering 2.04 volts. Any ideas on what effects this can/will have? Could it be causeing some graphic related problems in newer games? What can I do?
That sounds high. It shouldn't be over 1.8 volts.
You could be accidentally have upped it with a jumper change or BIOS setting. Check your board manual... you may very well either be unnecissarily overvolting your AGP card or your motherbard displays +.4v too high. It's more likely that you have it set at 1.8v and it's displaying +.2v too high.
Overturned PSU pots?
Thanks! Unfortunately it seems that there is no setting in Bios or via jumper(not in manual). Do you think this would be causing some nasty graphic stuff in newer games?
Hmm... well I'd leave it then. Are you having graphical problems in major games?
If it's a 1.5v video card, it should work in a 3.3v slot. Could be that you're trying to put a 3.3v vid card in a 1.5v slot
I'd double-check just to make sure.
So far the problems occur in C&C Generals, Ghost Recon and No One Lives Forever2. Some other demo's I can't remember. According to the Vid card manual the AGP Bus voltage should be 3.3. It's 3.18 which shows as acceptable to Smartdoctor software from ASUS. The AGP Bus VDDQ voltage is supposed to be at or around 1.5V. It's 2.04, which comes up as an alert in the above mentioned software. Attached is a screenshot. Sometimes it's better, sometimes worse. Sometimes different colors.
I'd try changing vid cards. STill any problems? ARe there settings for adjusting VDDQ?
You could have a faulty motherboard; probable sources of graphical glitches, however, are infinite.
No, the VDDQ doesn't seem to have changeable settings. I'm waiting to hear from the motherboard manufacturer. Both it and the vid card are still under warranty from the reseller, although trying to convince them that one or both are defective is another story. I will seek replacement nonetheless. Thank you for your help.
On second thought, I suspect that the overvolt is gradually frying your AGP Card, giving you those nice graphical glitches.
To the victor goes the [RMA] spoils.... our happy mobo is the most probable candidate.
