5volt Fluctuating Slightly

[Woofmeister]

I was playing around with my BIOS and I noted that my 5V Voltage was fluctuating slightly. Mostly it shows 4.84 but every once in a while it shows 4.78. Since the BIOS shows the 4.78 number in red, I'm assuming that is an abnormal reading. I've confirmed the fluctuation using ASUS probe.

I should point out that my computer is rock stable--I just got finished running Prime95 for 12 hours with no problems. Still, should I be concerned?

As you can see by my sig, I've got a 600 watt Seasonic, so I should have plenty of power into the 5volt rail. Also, because I had to RMA one of my graphics cards, I'm currently running with only one graphics card, so power should really not be a problem rigth now.

Anyone think I should worry?

Your limit is 4.75. Then after that, it falls out of the ATX spec. The BIOS isn't very good at detecting the *real* voltage coming off the line. You should check with a multimeter.

Ditto. I highly recommend using a digital multimeter. You should be able to find one on ebay for really cheap.

OK. Dumb question--Where/how do I attach a multimeter to test the 5volt rail?

it needs to be in contact with any ground (black) and a 5v (red)
