very sorry for the noob question here, but i've searched on google and found nothing. i see a lot of posts mentioning ACC. what is ACC? is this a bios setting? AOD setting? too bad i can't use AOD as i'm running windows server 2k8. also, i think i'm missing some bios settings, especially in the chipset section under pci express. i don't see the options for port #2,3, and so on. i wish i can access these settings to change the pcie setting to 16x instead of 8x. i have my two 4850 in crossfire connected to both blue slot which should be running at 16x in crossfire. i know they're not in 16x mode but 8x mode as gpuz shows that. btw, some specs

bios 0403
amd 5000+ am2 BE
4gigs gskill ddr2 800
asus m3a79-t mobo.

so far i'm learning more about this board. i'm going thru 50% of the posts on this thread. please help. you guys are awesome. thanks in advance
