Else you will screw up your graphics card eventually.) turn it on or use D3DOverrider to turn it on for games that do not have it. (Just for the benefit of anyone reading the title of this thread, if you hear your capacitors squeal like crazy, you have not turned on VSync in the game. Probably one wire from the bracket screw to a PSU screw would do it. When you earth things, if you need to use wire use good copper wire and use connectors and proper tools.ĭon't create too many wires as they act as earth loops and create/pickup noise themselves. make sure when you screw down the PSU that it is earthed to somewhere metal that connects to the rest of the components in the case (i.e. make sure when you screw down the MB that the screws are going to earth to the case by removing the paint to expose the metal I find coping with this high pitch hiss very hard, because the sound is so unnatural. I found out that after listening for 1-2 hours of this I can cope much better, but it's still tough.
#High pitch sound generator
Yours does seem to have enough metal though. If I'm feeling very stressed I use this noise generator and turn up the volume just so that I can hear the hissing on the same level.
#High pitch sound full
third thing is unrelated to your problem, but metal grills is better than a plastic one for shielding, but a full steel case is better as an earth as well. Table 2: Audiometric hearing thresholds of normal ears: conversion of dB SPL into dB HL (. no way to trust that the board is earthed Low and high-pitched sounds appear less loud to the human ear. no way to earth the card at the PCIe to case interface The mouse and keyboard are both USB.Īnyone have any idea what is the problem? I'm out of ideas… and start to be desperate. The screen is connected to the GPU with a DVI cable.
#High pitch sound code
Besides, now I have a permanent AE code in the debug LED. So, to resume, after trying everything, I discovered that if I turn on the PC without the screen, there are no problems, I connect it, and the high pitch sound starts. I turn it off, check everything, turn it on, again the same unbearable sound, seems from the GPU. Turn on the system, and suddenly a high pitch sound start coming from the PC. So I turn off the PC, I connect the Screen (DELL UltraSharp 2007WFP, 20.1"), the mouse and the keyboard (also old Dells from previous system). In some cases, the sound can be so loud it interferes with your ability to concentrate or hear external sound. All fine, all fans turning, got multiple codes in the debug LED and it did finish with 34, which I thing means everything OK. The noises of tinnitus may vary in pitch from a low roar to a high squeal, and you may hear it in one or both ears. I mounted everything, and before I connect the Screen/Mouse/Keyboard, I connect the power to check if everything was OK. GPU: Sapphire HD 4870 Vapor 2Gb(will buy new one in Christmas, maybe)
