RAM Voltage Issues

[crud_tud]

I recently put together the following system:

CPU: AMD Athlon 64 X2 4200+

MOBO: Abit Fatality AN8 SLI

Memory: 2 1GB sticks of Corsair XMS 184-Pin DDR SDRAM Unbuffered DDR 400 (PC 3200)

Video Card: PNY 7800GT PCI Express

Power Supply: Seasonic S12-500

This is the second system I've put together and I think I've got everything connected correctly. The system boots up and runs, but there seems to be an issue with the RAM voltage. When I load up the computer my ABIT EQ software automatically loads up in my system tray and when I maximize it I see that my DDRVTT voltage meter is showing red at 1.45 Volts. The problem seems to go away if I open up Abit OCGuru and change the system mode to quiet -- that brings the DDRVTT down to 1.34. Even then, I have problems. My computer will freeze up while encoding audio files or even downloading a large file off the internet. Either the system will just hang with an unmovable cursor or sometimes I will get the blue screen. When I do get the blue screen it always shows the same message, which I jotted down once. Here is most of it:

Problem detected and windows shut down to prevent...

DRIVER_IRQL_NOT_LESS_OR_EQUAL

STOP: 0X000000D1 (OX00000002, 0X00000001, 0XB2F1BAB6)

NVTcp.sys - Address B2F1BAB6 basee at B@F19000, Datestamp 421e79ad

This seems to be happening more and more often. Here are some of the things I've tried to do to solve the problem or narrow it down:

1. I flashed my BIOS using the the flashmenu (I had to update the software off the web). No improvement.

2. I tried every possible configuration of RAM, moving my two sticks to slots 3 and 4 (from 1 and 2). I tried using just 1 stick (tried both that way) in slot 1, then 2. I finally tried using a spare set of RAM sticks (Patriot brand ddr400 512MB each -- I know they work fine because they're from my old system) -- and still had the same voltage problem. So it's not the ram, right?

3. I unplugged and replugged the three power cables (2 go into the motherboard and one goes into my 7800GT). For good measure I then unplugged and replugged every other connector in my system as well. No improvement.

4. I just this afternoon reformatted my HHD and reinstalled windows, thinking perhaps some software issue was causing this. Still no change.

Any thoughts? I'm at a loss myself and am beginning to think I have a bad motherboard or powersupply.

what HD are you using IDE or Sata... may try changing the cable....

Thanks for the reply. I've got a 74gb raptor connected through sata cable. Could that be affecting my ram voltage, and if so, how?
