This is a poll about the presence of electric noise in P55 based systems. If you have one, please vote!
It would be great to have details of the system on which the electric noise is or is not present. Also, if you have a fix it would be great to know which one are you using.
So I guess a good way to get some info would be voting and filling this little form with manufacturer and model:
Processor:
Motherboard:
Power supply:

Does your P55 rig have electrical noise?

Processor: i5 750
Motherboard: Gigabyte P55A-UD3R
Power supply: Corsair HX620
Graphics card: Sapphire 4670 Passive
Electrical noise: Yes. Some in the PSU and some from the motherboard.
Fix for electrical noise: Running the CPU at a fixed Vcore.
Description of noise: Sounds like "cri-cri-...". It happens mostly when the system has been idle and gets a peak of activity for a few seconds, like moving or scrolling a window. Also happens if the system has just finished a period of high activity and it is followed by a low activity one. The tone of the sound varies with CPU activity level. Also, the sound was present (with a slightly different tone) with a Seasonic S12 PSU.

Yes!
Processor: Intel i7 860
Motherboard: Asus P7P55D
Power supply: Corsair HX620
Graphics card: Asus EAH4870 Dark Knight
Electric noise: YES, from the PSU only.
Fix for electric noise: Partial fix by disabling C1E and SpeedStep

Processor: Intel i5 750
Motherboard: Asus P7P55D Pro
Power supply: Antec CP-850
Graphics card: Palit GTX260 216
Electric noise: Yes, unsure of the source.
Fix for electric noise: Seems to be fixed by disabling all the CPU power management settings in the bios (C-state stuff... turned everything off)
Description of noise: laptop-style coil whine, depends on load
Might still be a bit of noise left, tolerable.

A bit late to the party...
Processor: Intel i5-750
Motherboard: Asus P7P55D-E Pro
Power supply: Corsair HX750
Graphics card: Asus EAH5850 DirectCU 1GB
Electrical noise: There's a high pitched ringing (a constant "eeee" noise) that comes from around the socket area of the board. This happens when the processor is idle.
Fix for electrical noise: Apart from a 'workaround' (with limitations) of disabling both "C1E Support" and "Intel(R) C-STATE Tech", there is none.
Description of noise: I've had two of these boards, from two different online stores, that exhibit the same problem. There's a thread over at bit-tech (title: ASUS P7P55D-E PRO high pitch noise) that has more information about solutions I've tried (can't link, too few posts). It looks like the noise issues can be very hit or miss with users of this board.
Anyone have any experience with an affected board and a replacement or different board that doesn't have the noise, preferably with the same components?

Processor: Core i7 860
Motherboard: Gigabyte P55A-UD5
Power supply: Antec CP-850 / Seasonic S12II-430
Graphics card: Gigabyte Radeon HD 4850 (semi-passive via Arctic Cooling Accelero)
Noise description and solution: There was chirping sound coming from the both PSUs, roughly at the same volume. It was solved by disabling C1E and SpeedStep. Also, there is some coil whine coming from the motherboard (when CPU is idle), but in practice it is not audible in normal use, especially since the case is placed under a desk. However, I think it would've been a problem if my target had been a near-silent system instead of just a quiet multi-purpose rig.

Processor: Core i5 750
Motherboard: ASUS P7P55D
Power supply: Nexus RX-6300
Graphics card: Sapphire HD5850
Electrical noise: Yes: high-pitched noise coming from the PSU. It's especially noticable in Google Chrome, in games, when watching movies and after waking up from sleep mode.
Fix for electrical noise: Partially fixed by disabling C1E, Speedstep and C-state in BIOS. Most of the high-pitched noise in Chrome or when watching a movie is now gone (it's still there, but very faint). The noise is still loud in games.
Description of noise: Chirping, which changes tempo and volume when scrolling in Google Chrome, during a scene change in a game, etc.
Notes:
Using a SilverStone Raven 2 case with all fans set to LOW
PSU got replaced (by same model) but that didn't solve it (the delivery people dropped my rig though, so maybe it did solve it before it arrived).
