USB clock

Perhaps I am misunderstanding as I am quite new to this, but don't many DACs have an onboard word clock that would fix any jitter caused by funny RAM timing or frequency rates? Also, doesn't USB itself re-synchronize the packets?

My setup uses 3GB of no-name DDR400 (2x 1GB, 2x 512MB) running in dual-channel mode at 800MHz. The processor is a P4 Prescott (or PressHOT for those of you in the know) with Hyperthreading that draws around 95 watts alone. The motherboard is a SuperMicro (good quality, made for workstations) and the power supply is some 500 watt brick I pulled out of an old server. The video card is overclocked as well.

According to what I've read my PC is doing everything wrong to be suitable for audio transport. But I have compared it to 3 other computers -- Apple Macbook, Toshiba notebook and a Dell workstation -- and they all sound absolutely identical through ASIO.

I would think the motherboard's power supply would be among the most important factors in quality audio via USB.
