High pitch whine from speakers since new card

[Souness]

Installed my new 7850 today, and whenever I run a game I get an irritating high pitch whine from my speakers. It happens on the game menus too, but not at all on desktop, or watching movies etc. The frequency of the sound seems to change depending on what is happening on screen. For example, if the menu goes from a light to a dark background, the pitch will change a lot, but if I just move the mouse cursor it will change a little.

Any ideas?

whats your full system spec including psu?

system is roughly 2.5 years old

Corsair HX 750W
i7 920
Gigabyte GA-EX58-UD3R Intel X58 (Socket 1366) DDR3 Motherboard
6GB RAM
MSI HD 7850 Twin Frozr III OC 2048MB GDDR5 PCI-Express Graphics Cards
Onboard sound

Changed gfx from a 5850

The whine is your girlfriend/wife moaning about the money you just spend on a graphics card .

lol

can you pop in the bios and try this,see if it reduces or stops the noise completely,disable c1e then look in windows power saving options and make sure you choose "balanced"

you probably need to switch psu to anothe rbrand or an updated version

I checked and both those things were set that way already

why would I need a new PSU? This one was working fine with my 5850, and the 7850 doesn't even take as much power!

because its not shielded enough from emi,those new cards seem to emit more than older gen

could be the vrm inductor noise,from what ive seen and dealt with 9 times out of ten switching the psu fixes it,can be the gpu but mostly psu

some make the noise more than others,ive helped a lot of folks on another forum with this problem from x58/p55 onwards

disabling eist in the bios might reduce it or stop it aswell but the cpu wont downclock at idle

its interference between the cpu power saving or mb and the power supply

damn

I'll try that EIST thing

it always seems to be the way... upgrade one component and you end up getting another 3 just to make it work! I remember when I upgraded to a 5850 I ended up getting a whole new system, lol

btw, is the interference actually damaging stuff or is it just innocently annoying?

 

[Souness]

Nope, no dice.

I can't afford to change a perfectly good PSU and RMA'ing it would be too inconvenient. I guess I'll just grin and bear it if there's nothing else to try.

Thanks for the help

I have the same mobo, and it's an inherent problem with them when used with certain PSU's. According to GB website, they recommend turning off/disabling the CPU power saving features in BIoS to reduce the coil whine.

My power saving features were off already (I forgot to reactivate them when I was done overclocking).

Dude get that PSU changed, you shouldn't have to grin and bear it. It's like watching TV with the vacuum on!

Can't afford the inconvenience of a dysfunctional PC while PSU is being RMA'd (not even guaranteed to work).

It's not as bad as a vacuum... it's more like having a mouse under my desk. I played a game of AoE last night and forgot about the noise completely after about 10 minutes.

I guess I'll try the sound driver thing, but not really expecting it to work.

This happened to a mate of mine we all thought it was psu whine he was about to change it when he decided to reinstall his sound drivers and it worked they must have got messed up at some stage installing his new graphics card

Tried... no luck.

Move your cables around mate..... That will fix it. Had same thing its cables touching each other
Not PSU not GPU.

This was my first thought when it happened. Could not see anything touching but will have another poke

Are you using a HDMi cable? Try Dvi and see what happens.

DVI

What revision is your mobo? IIRC, rev1.0 have this problem and there is nothing you can do apart from trying an RMA. Rev2 boards had hardware changes made at production to reduce this MOFFAT whine.

Rev1.6.... are those affected?
