View Full Version : High Pitched Buzz coming from new 6800NU

01-02-05, 12:44 AM
Hi All,

I've just been building my new system and everything was going fine, until I started benchmarking to see how well it was performing...

Whenever my 6800NU is put into a situation where there is something graphical going on, it emits this high pitched buzzing sound - that varys in intensity depending on what it's doing. I can hear it very slightly when I click the start button and the start menu fades up... and it becomes VERY audible and sustained when I run 3DMark.

The card is still performing like regular as far as I can tell though, my scores in 3DMark are decent.

I've tried giving the card different molex connections, even ones completely to itself, but it still makes the sound.

Any ideas what this could be, and how I can fix it? It's very annoying.

My System Specs:

AMD Athlon 64 3200+ (939)
Asus A8V Deluxe
Corsair 1GB DDR-3200XL
eVGA 6800NU 128MB
430W Antec TruePower PSU
200GB Maxtor 7200 RPM HDD

I remember this problem before... I believe it has to do with the card causing inteference with the Soundcard/onboard sound. Do you have an extra soundcard that you can throw in?

Wow - thanks for the quick reply.

There are currently no speakers plugged into the system.
I've even tried disconnecting the PC speaker to see if that was it, and it still made the noise.

What power supply do you have, the 6800 cards will let off a high pitched warning if it's not getting enough power.

I listed it in my system specs - it's an Antec 430W TruePower PSU.
It's only powering one HDD and a DVD-RW drive right now - other than the 6800.

I had this problem with my old 5800... I'm pretty sure it has to do with interference of some sort...

Exchanged the card with an identical one at the store today... and it fixed the noise.
Seems like it was simply a faulty card... maybe crappy capacitor or something.

Thanks for the help all.
