I remember that with the UD3R rev 1.0, the first 2 I got had the noise even after disabling C1E, but the third one had no noise after disabling C1E. So, there is some sample variance in the motherboards. However, I found that regardless of what C1E setting you have, you can eliminate the noise coming from the motherboard by fixing a vcore voltage value, rather than leaving it at Auto. Maybe you want to try that.
Thank you thank you thank you!
Fixing the vcore voltage works.
I set me vcore to 1.25v
Turned off turbo.
My machine now works at full clock with C1E enabled and NO NOISE.
Still, it would be nice if this problem was fixed completely.
Having a fix vcore is the same thing is as turning of c1e. Google C1e for more info.
Maybe, but the results are different.
In order for me to get rid of the noise, I had to turn off BOTH C1E and C3/4/5 (or whatever it is).
My CPU would run at 130-140W and would not go below 70 degrees.
Now with the voltage fixed, and the two options above turned on, the wattage goes down as low as 40W and the CPU dips to 60 degrees when idle.
Though I agree, this isn't as good as letting the voltage change (where temps would drop below 50 degrees), it's still better then the state before.
I got an RMA for this board.
I'm going to pick up an Asus board (can't decide witch one. I have the original P6T at work and no issues).
Then I'm going to send this POS for an RMA replacement and then sell it when I get a new one back.
