10.4: Eliminate excess fan noise under 10.4.3 on G5s
This may be a separate problem, but what is that electronic noise I hear when I move windows, or play full screen video sometimes? It's really annoying...any fix for that?
10.4: Eliminate excess fan noise under 10.4.3 on G5s
That, my friend, is the bane of sound engineers on PCs since the bane of time. The buzzing is caused by the bandwidth limitations off your PCI bus. When you move windows the graphics card is using it's "hardware acceleration" to make things snappy, which introduces noise into the sound card b/c of the limitations of the PCI design. Of course, with hardware acceleration turned off for 2d operations, it goes away, but whether that'll work under OS X, I don't know. The hardware gurus have promised a fix for this every year since PCI came out, so don't hold your breath. It's much, much worse on Windows machines, but a number of good sound cards can avoid this, and many MoBo audio chipsets. Sorry, but you're stuck.

AFAIK, this is not just limited to the PCI bus; my old (very old) 386 used to do this as well, using just ISA cards.

Maybe you are talking about the problem by having "nap" mode enabled? On G5s this mode issues a very annoying high-pitch sound on certain operations. Anyways, you need to download the CHUD tools at Apple and disable nap mode to fix the issue. |
