Possible power problem? Bad voltages?

Here's my setup:

Asus A8V Deluxe WiFi edition
Athlon64 3500+ (2.2Ghz)
2x512MB corsair DDR400 2-3-2-6
2x 74GB raptor
300GB SATA seagate
80GB PATA WD
a cd burner & a dvd burner
gefore 6800 ultra OC
Antec True Power 550
Creative X-fi music


The problem I'm having is that every now and then, I'll get a pop up warning saying my graphics card has detected that not enough power is being given to it, so it is underclocking itself to prevent problems. Now this card has 2 separate power lines going into it. When this first started happening I removed all other devices from the two power lines (cd burners, hard drvies, even fans). So both lines are clear of anything else. I don't know if they're independant lines, I don't know if this PS even has 2 independant 12V lnies.

Well I instaled motherboard monitor 5 to see what's going on. I think I have the correct chipset, but the readings seem off. The temperature and fans reading seem correct, but not the voltages. I have the Winbond W83627THF-A selected and the readings I'm getting are:

core0 1.58
core1 3.02 (I have no idea why it reads a second core)
+3.3 3.33V
+5 5.03V
+12 16.32V
-12 0.00V
-5 0.00V

Now if I choose msi 848p neo as the configuration instead the reading I get are:
core0: 1.58V
core1: 3.02V
+3.3: 3.34V
+5: 5.03V
+12: 12.00V
-12: -178.60
-5: -6.7V

The msi 848p neo configuration is the only one showing the 12V line at 12V. Some of the other selections show the line as haveing 11.45V, and the Asus P4C800 E Deluxe settings shows 12.18V, all other readings are the same as above, except core 1 is at 0.0V.

Now from what I can find, the top one I listed here, the winbond W83627THF-A is the correct setting for my motherboard, but if that's the case, those 12V line readings concern me.


In any event, I have the gimps program and F@H running constantly on this PC, and it's completely stable for weeks. I have seen the problem pop up while playing World of Warcraft, but I've also come back to my computer and had the message popped up. I'm at a loss as to why the video card reports under voltages. It doesn't seem to happen very often. I sat here one weekend for 6-8 hours coding and gaming straight with absolutely no signs of any problem. Another day I sat here surfing the web and had the message pop up 4 times in an hour.

Now, I have been thinking of going to 2GB ram plus an Opteron 165, and I'm really concerned that the added stress will exacerbate my problem here.
 
The only way to see if your voltages are correct is to use a multimeter.
