I just upgraded to a MSI 8800GT OC from my old 256mb 8600GT, and everything seemed to be working without a hitch until I pulled the side of my case off yesterday to adjust something. The card is constantly emitting a quiet high pitched whine of sorts that varies depending on the load. I know it's not coming from the fan and it doesn't sound like it's coming from the power conditioning part of the board, but rather closer to the monitor connection side. I did contact MSI about it and their tech support claims its normal, so I've since been trying to figure out how to eliminate the noise.
Google came up with a load of the same problem for people with the GTX, but not so much the GT. I tried holding an eraser to the larger capacitors and inductors to try and stop vibration as some people suggested, but that didn't seem to help at all. Oddly, when I disable my second monitor the noise goes away almost entirely unless there is a heavy load on the card. This seems to indicate that input power is the problem, but I checked the supply with a meter and under heavy load the 12V rail is sitting at about 12.11V with very little ripple. Is there anyone else with this issue or some advice on fixing it? I'm trying to avoid the RMA route for now because I don't want to wait 2 weeks and pay shipping just to get another card that does the same thing, and aside from the whine (which I can't really hear over the fans) the card works flawlessly.

I don't know if its any help but my graphics card makes a similar noise to what you've described while under 3d load, which can change in volume and pitch depending on whats on the screen at the time. This was back in like june last year when i bought the card (7900gt) second hand, installed it and heard a not-so-loud but still definetly audible 'squealing' kind of noise. I checked the power connector, reseated the card, etc etc and the noise has never gone away. A change of cooler to a much better zalman model didn't change anything either. I thought the card would be flaky and die on me but this never happened and its been very stable even with a heavy overclock. At the time i got the card and discovered this noise i put in something like 'squealing noise graphics card' into google, and i got quite a few relevant hits. The opinion was that yes either a capacitor or voltage regulator was at fault (imperfectly manufactured) and that the card could either quickly die or carry on just fine regardless. I remember reading some posts on some forum somewhere from people with 'noisey' cards that were working normally albeit with a little disconcerting noise being produced from them. You've rma'd the card so it doesn't matter anymore but i would like to say that this does happen sometimes and is not necesarily a sign of impending doom. Mines working fine almost a year after purchase, and even then was second hand. Cheers
