The other thing is having more than 4GB of RAM. Use the switch "maxmem=4096 -v" without quotes in your com.apple.Boot.plist or at Chameleon when choosing the OS. It isn't in the graphical options, but if you just start typing you'll see it at the bottom of the screen. Also make sure that you're using AHCI mode for all SATA controllers until you get the system going.

I personally have a Phenom II 550 and a GA-MA790FX-DS5 (nearly the same chipset) and used these methods to successfully boot Snow Leopard.

Good luck.
Actually I have multi at 15, my Phenom works at 3.0 Ghz all the time, all drives are set to AHCI, and I tried booting with maxmem=2048 on Chameleon but it didnt help

I envy you, you have a working SL
What guide did you follow?

GA MA-790X UD4P, AMD Phenom II X2 550
8 Gb DDR2 667 RAM, ATI HD 3850
WD 640 Gb, Seagate 320 GB
Win XP 64bit & OSX 10.5.5
