Ok this is gonna sound REALLY weird but...

Post by LazyCoder » Thu May 24, 2007 1:35 am

Whenever I have 10000 static particles, my computer makes a strange noise every time blender redraws the view. Like I'll rotate the camera and I'll keep hearing this beeping noise coming from inside my computer, not from the speakers.

When I turn off static, or lower the amount below 2000 I can't hear the noise. Above 2000, the more particles I have, the louder the noise.

My specs:
- 2.33 GHz dual core intel
- 2048 MB memory
- 256 MB ATI radeon mobility X1800

So freakin annoying.

What kind of noise? Is it the gfx-card fan speeding up but grinding because it's a bit old or dirty?

That sounds like swap memory (hard disk) in use for me. Though with those specs it seems a bit strange but it may be a reason. You did not mention which operating system you are using. This information might enlighten the situation a bit. Other systems than Windows generally can access more memory (>1 GB iirc) in case of Blender. There's an experimental patch at the tracker to remedy this limitation though.

LazyCoder - don't worry, you're not entirely alone in peculiar noises happening! When I drag nodes around, I get a hissing noise coming through the speakers... I think computers just like to keep you amused really!

Same thing here!

It is a wierd crackle as I rotate round the 3D view at times. Stop moving and it stops crackling. That said, I've noticed the same thing with some command line programs too - is the command line/console is generating loads of output I can hear it with my speakers turned off!

No it isn't the disk swapping cause I know that sound!

... and if you get enough of them it almost sounds like crickets? lol

I'm on Windows XP, and I assume it's sp2 because I got the computer after sp2 was released.

So there's nothing really wrong with my computer? It's just kind of annoying that's all.

This happens to me on my ATI notebook. It has always done this whenever the gfx chip has a lot to handle. it goes like "zzzzzzzzzzzzzzz". Hey that's a good imitation!
