Capacitor whine while folding on gpu question for the knowledgeable masses....

post #1 of 8
Thread Starter 
If this is a double-post would a mod please move, not sure if I posted it correctly last time I tried...

Ok, so I am aware that the capacitor whine question is akin to beating a dead horse, but...
I recently added gpu folding to my sig.... now, I am not bothered by the whine, but it does annoy my better half. So, I loaded afterburner and lowered voltage from 1850mV to 950mV, core clock from 900MHz to 750MHz, and shader clock from 1800MHz to 1500MHz. Which helped reduce the whine so my better half dosn't complain about it anymore unless she gets within a few feet of my corner of the world.
Will I be okay running my card this way? I don't see why it would be a problem due to under-clocking... but I wanted to double check before I let it run 24\7

Thanks
cheers.gif

sory to ask question in your thread but how can you tell if it is gpu or psu i get that whine when i fold if my gpu is overclocked?

If it's actually the card, I heard nail polish over the whining capacitor reduces the buzzing sound. You're just suppose to make sure it's 100 percent dry before powering it on.

since I have 3 480's folding, I have a lot of cap squeal.. My psu also makes a squeal sound when everything is loaded. It's normal when running lots of current through your system. Mine is over 1000w loaded and gets even louder if I overclock my cards even more. You will get less PPD if you under clock your card. Be lucky you don't have to listen to 3 of them tongue.gif

It's a high-pitched tone, not a buzzing sound. I would never coat a capacitor with nail polish, unless you wany to seal the heat in.wink.gif

are you sure its the capacitior? i think you have what is known as coil whine, when you have chokes that vibrate and create that high pitched squealing sound. Capacitors arent supposed to whine... some resin or hot glue will fix your issue. It normally goes away after a bit of time though.

If I change my 480's from 800 to 825 the squeal gets louder and higher pitched. Go to 850 and even louder. I have heard this from day one with my 480's. My system is all on water and is almost silent. I can hear where the sound is coming from. I have a tech bench and my psu is on a different shelf. Gpu's for sure.
