I don't know what thread had someone mention a whine when folding on their GTX460, but I'm going to post my feedback in this one.

Just got a Gigabyte GV-N460OC-1GI (that's the 1GB GTX460) and have been running it for about an hour now. Whomever reported the whine while folding on their 460, I'm getting it also and it's ANNOYING! This card is dead quiet at idle compared to my old card (8800GT). Once I fired up F@H, I immediately heard the high-pitched whine. What makes it even more annoying is it oscillates as you use the graphics card for the GUI, like grabbing a title bar on a browser window then wiggling it back-n-forth to use the GPU. That makes the tone warble to make it even more distracting.

I'm going to try and record the tone and post it, but I'm not sure my headset mic will pick it up.

I haven't come across any posts about whining noise with GTX 460 but I have read a post about an NV GPU and for some, it helped to OC the GPU to remove the noise as it when out of hearing range. I think that it has something to do with the digital/analogue PWMs or something. What temps are you seeing on your GPI? Does increasing the Fan speed helps?

I have to go to class tonight and don't have time to mess with it today. I'm trying to record the tone so people don't think I'm nuts. :)

After tonight though, I'm willing to be a test case to try stuff to get rid of it so we can have a good list of things to try for other people to try when they buy this card.

Initial quickie observation with GPU-Z is it's hovering around ~59C with side of computer case off and it went up to ~61C with the side back on. Idle temp is ~33C. Fan speed stays a constant 40% both at idle and while folding.

Some GPU board whine. The boards use VRs which manage the power to the GPU and they can vibrate, depending on how they happen to be attached to that board. The frequency depends on how much power is being drawn so sometimes you'll hear it and sometimes not. Something like nail-polish and damp the vibrations and/or change the frequency. Some people have returned their GPU to the manufacturer for an exchange and that may help, depending on how the VRs are attached to an individual board.

I'm not sure what "VR" and "PWM" are short for so I can't look them up in Google images to see what they look like. I can visual ID capacitors and resistors, but don't know what those two are.

As bruce noted, nail polish to harden and solidify the mounting, not nail polish *remover* which could potentially damage the board if you got the good stuff. :twisted:

Not that I'd typically know anything about nail polish remover, but it (the kind that still has some acetone) works great as a parts cleaner in a pinch if you don't have IPA, paint thinner, mineral spirits or any kind of spirits. ;)

Thanks for the explanation. I'm having flashbacks to my 6 months of USAF Basic Electronics training back in 1989. :shock:

As a follow up, I can't record the tone. It's beyond the upper end of what my gaming headset's mic can pic up (Makes sense since it's intended for voice comms). Oh well, no biggie.

Never knew that :shock: changed my post to ensure that no-one damages their GPU

I read it as "nail polish", so no harm would have been done. I never would have put water/acetone on my card anyways, so it's all good. :)

Lets see how good your are :lol: I Googled and found this article with pictures where they investigate the coil whine an tell you how to fix it with nail polish. Personally, I never ran into any issues with my 4 Nvidia GPUs (currently on 5 one) and due to the high cost of GPUs here, will never dare to operate on it. Hope your GPU makes it out without any issues if it opts to undergo the surgery.

Not a peep, or whine, out of my, now, 14 nVidia cards. I've been folding on 10 of them, hard, for several years. The reports I've seen seem to show a problem with some brands. I have XFX, BFG, and EVGA.

I think there were earlier reports of whining with 200-series MSI boards.
Proud to crash my machines as a Beta Tester!

My Gigabyte 6600 Ultra, Gigabyte 7800, ASUS 8800 GTS 320 MB, Gigabyte 9600 GT 1 GB, Gigabyte GTX 260 SOC never made any noise at all. The only noise that comes is from the GPU fan @ 100%. The safest option I guess is that you RMA the GPU and hopefully you will get a silent one.

I have the GV-N460D5-768I-B i.e. the 768M version of the same card, and it runs cool and quiet, not a peep.
The temp is 61-63C when folding at 805/1610/1600 with 10152 PPD

(I am not a gamer, the GTX 460 is folding dedicated 7x24, that's why it is only 768M i.e. 192bit memory bus)

There's a better solution to the whine: acquire tinnitus as bad as mine. You won't hear the whine at all!

Hmm, if I put nail polish in me ears, will it fix the whine? What about acetone? :e?:

I've been thinking about buying 460's for Folding and have wondered about those memory bus specs. I wasn't sure if that referred to accessing the system memory or the video memory. It seemed like the first would not be very important but the second would be. So, is there no particular reason for buying the version with more memory and a bigger memory bus?
