Something wrong with this pic?
I've been working on setting up a Q6600 with 4x1gb memory on the Abit board and just noticed something during an OCCT run ...

I got so use to the 45nm CPUs reporting I was surprised to see the temps flip on the Q6600 with the mobos monitoring temps lower than Coretemp. Unless someone tells me different, I'm inclined to believe the mobo monitoring. :confused:
Absurd EMI on this board...
So, great story -- after finally dialing in my 24/7 stable overclock and nailing down the voltages that I wanted, I turned down the fans to a more reasonable level and have noticed that I have the dreaded high frequency noise resonating from somewhere on my IP35 Pro. Even worse, I plugged studio headphones into the rear audio port and can hear HORRIBLE electrical interference coming from the board.
A few things I've learned about the problem:
1) Changing my PSU (Seasonic S12 650W) out with a Seasonic S12 550W didn't help the problem at all -- possibly a problem with Seasonic PSU's & the IP35 Pro, but doubtful.
2) Manipulating the PS/2 port with my finger alters the frequency of the sound, but doesn't eliminate it.
3) Unscrewing and re-seating the motherboard doesn't help.
4) The sound is clearly coming from around the PWM area.
5) Reducing my overclock back to stock frequencies/voltages didn't help.
6) Disabling C1E/EIST, onboard audio, both ethernet ports, and pretty much every other feature on the board that can be adjusted in BIOS didn't help.
7) Changing my BIOS from 16 beta 04 to release 16 didn't help.
8) The sound changes in intensity based on CPU load -- setting my G9 mouse up to a polling rate of 1000 makes it much more intense anytime I move the mouse.
9) I stopped by home this afternoon and tested for the presence of this interference and high frequency resonance in the system I built for my parents a few months ago, which features an IP35 Pro w/ an E6400 overclocked to 3.44 Ghz (and the 550W Seasonic PSU that I "borrowed") -- their system has no interference issue... plugging my studio headphones into the rear jack yielded sweet, dead silence...
10) So even if I can find a way to kill the high frequency sound, the interference is still there and that's the real problem.
So, is the interference I'm experiencing unique to my IP35 Pro (or a small % of bad ones), or are there other things causing the interference that I haven't explored yet.
The only other thing that comes to mind is my 8800GT SSC -- but I haven't been able to find any other people with major interference problems from it.
I would just RMA it, but others with this issue claimed that it wasn't corrected by the RMA, and Abit's policy towards advanced RMA's is awful (they take a $157 deposit, make you pay $15 for shipping the refurbished board to you, and then will MAIL you a check for $150 when you send the board back...), so I might as well just buy a new board and sell my IP35 Pro (or RMA and then sell it).
Opinions/advice?
