Hi pitched noise during 3Dmark06!!

[Solouko]

i've just done my first overclock on the system in my sig, and i've fgot the processor up to 2485MHz the memory running at 235MHz, but i think it's the auto overclock on the graphics card that's doing it. i've used nVidia coolbits in the graphics card setup to automaticaly overclock the system, now, when i run 3Dmark06 all through the video tests the system is producing a REALLY loud high pitched noise!

now when i minimis a window to the task bar or maximise it it also makes the same noise, but at a lower pitch and a lot quieter, so i'm thinking that it's the graphics car that's producing it.

My big wory is that it's the graphics card memory, now i've got the CPU and GPU running on water cooling, but when i took the stock cooler of the GTX i didnt put any kind of heat sink back onto the graphics card memory, i've had people tell me that you dont really need it on a RAM chip. however i'm really worried about this noise now!

I think I've heard stories where the capacitor's on 7900s can vibrate under load creating the high pitched noise you speak about.

yes, it does sound like a capacitor, i've heard tham make noises like that before!

so, why's it only just started and how can i stop it :3

i've just rebooted and nothing makes any abnormal osunds until i run 3Dmark06, now i've run it many times before with no problems, i've even returned the card to it's stock speeds but it doesnt seem to have helped.

If it only does it during 3dmark06 I would just leave it but check it with other games to make sure. Not sure what you could do to stop it once you've got it to be honest.

I had this issue with my old Asus A8R32-MVP ATi motherboard.. the noise came from capacitors during memory intensive tests/benchmarks. Thankfully a bios updated fixed it.

What board do you have?

i've got a DFI lanparty ultra-D, and the bios has already been updated.

the sound doesnt just happen with 3Dmark, after i've run 3Dmark the noise is there whenever i do anything graphixy, like minimise, maximise a window or even scrole! it's more then a little anoying

i'm going to run HL2: Lost coast to see if that generates it

Update:

Yes it happens in lost coast but only for a few moments periodicaly everey 3 of 4 minutes, during the lost coast video stress test there was no noise

i had that really bad with my 3200+, especially with scrolling, and i also had it when went into graphics settings on the 6800gt, making the screen go black and then come back on again, and also when i right clicked on a video file (avi).

now with my 4600+ it happens when scrolling on the list of servers on BF2. i thought it was coming from the cpu area, but im not too sure.

same with my 7800..... REALLY ANNOYING!!

A similar problems in can occur CRT monitors. Due to thermal expansion and contraction the solder holding the the HT capacitor pins/leads to the circuitboard tends to crack and produce a poor contact, similar to a dry joint. I don't know the physical explanation of why an alternating HF voltage should produce audible frequencies when applied to caps with poor electrical contact to the circuitboard. However I have resolved this on several monitors by re-soldering contacts that appeared cracked under a magnifying glass. These can be a pain to find and often it is quicker to just touch up all pins of all caps on the circuitboard.

Will this apply to and work with graphics cards or CPU power supply caps I don't know. But it works fine with CRT monitors. If you try this method, just a quick touch of pins enough to melt the solder on the reverse side of the circuitboard is all thats required. Do not over heat the components.


Just a thought.

Good luck

I've recently had a similar thing happen to my old Pelted x800 - take manual control of the overclock and drop it back a bit - sorted the problem for me! I like the degradation theory - only started recently and the cold hammers the joints!
