Thread: Help--High Frequency Wine in Turbo Mode for Asus P4P800

    I just finished overclocking a new P4P800 from Asus (new board from NewEgg):

    P4 2.6GHz --> 3.25GHz, FSB 1005MHz, OCZ PC3200 Dual Channel 256MB pair. Win XP home, SP1. Seagate S-ata 80GB 7200 rpm.

    Retail Intel fan, 400W high quality power supply.

    The last tweak I entered in the bios was to enable the "turbo" mode. Everything works great and I just finished a 6 hour p95 torture test without error. But, I now have a very high frequency noise (like scrathing a blackboard) coming from, what appears to be, the mother board when the PC is doing significan calculations (e.g. benchmarks, torture tests, graphic manipulation, etc.). When the PC is idle or under low processing load, their is no noise. The fans are not the problem.

    The high pitch noise is driving me crazy! I mean it is really a high frequency, on the edge of human hearing.

    Has anyone ever heard of this? The noise started when I enabled the turbo mode.

    Are you absolutely positive it is not a fan somewhere. Motherboards do not make noise. Something has to be moving, like a fan, hard drive, or cd rom drive to be making the noise. I could be wrong, but nothing other than fans on a motherboard or processor would make any noise at all, no matter what.

    That is what I initially thought too, but the fan rpm does not change with additional processing and the noise seems to be aligned with processing. How about a crystal oscillator, or other oscillating component on the MB.

    --my fall back is that a drive is about to die, but these are brand new and why would the turbo mode cause a failure or the noise?

    --very odd.

    Oh, there is one benefit, every rodent and insect within a block has moved out.

    Ya know, Id call tech support. I never heard of this before, but tech suport has heard everything 20 times over, so since its new its gonna have a warranty so Id call em and find out if they can fix it, or if not, replace it.

    Ok, got the answer. It was the Opti UPS backup from which the PC draws its power. This is very odd, but under heavy processing loads an intermittent warning buzzer was being triggered at such a high frequency that I could not recognize the source. The audible frequency was so high that I had difficulty finding the source.

    I thought the same as Tweater that it was a feedback problem in the one of the speakers. I finally physically moved everthing around to isolate the noise and saw a correlation between a weak flashing light on the back of the UPS and the noise.

    I have a 400W CoolMax Taurus power supply in the PC, so I do not understand why the USP was freaking. Changed to another UPS--problem solved.

    --good grief!

    thanks all.

    I have a K8V SE Deluxe, and it's doing the same thing. It has three inductors, from the top down the third one is emitting the high pitch noise. I touched (gently pushed) it and the frequency changed. Now it seems to have stopped doing the noise.
