AT Bus Clock??
This is a discussion about AT Bus Clock?? in the Windows Hardware category; Just wondering if anybody could help explain to me what exactly is the AT Bus Clock setting in the Bios for. I have a Gigabyte Supersocket 7 mobo and it has these options: Auto Sync Bypass CLK2/3 CLK2/4 CLK2/5 CLK2/6 7.

CLK/3=SX/DX16,DX20,DX25,DX2/50,DX4/100
CLK/4=SX/DX33,DX266,DX3/99
CLK/5=DX40,DX2/80
CLK/6=DX50,DX2/100
CLK=half speed of processor
/x=divider
ex: If I have a 486DX4/100 then my settings would be:
CLK/3
Reason:
CLK=33X3=99mhz
CLK/4=SX/DX33,DX266,DX3/99
CLK/5=DX40,DX2/80
CLK/6=DX50,DX2/100
CLK=half speed of processor
/x=divider
ex: If I have a 486DX4/100 then my settings would be:
CLK/3
Reason:
CLK=33X3=99mhz
33=bus speed
OP
err...thanks but somehow that just confused me even more, hehe...me a computer idiot...
currently it is set at auto and has CLK2/4 set, I have an AMDK6-2 450MHz (2.2v) cpu. reason i was so interested is that i have tried in the past to overclock my cpu but couldn't get it to boot and was wondering if this had anything to do with it.
current settings is 100mhz x 4.5

Change 4.5 to 5.
OP
tried that already before, these are things i tried in the past:
switched multiplier to 5 (wouldn't boot up)
switched multiplier to 5.5 (wouldn't boot up)
switched the FSB to 105 MHz (wouldn't boot up)
etc. etc...FSB increment of 5MHz
also even tried to up the core voltage, wouldn't boot up.
the only thing that would allow me to boot up was a simple core voltage 2.4v but still running at 450MHz

oh yah, another thing i was wondering was video cards and their bios. I have a TNT card and replaced it with an older SiS AGP card but the pc would not even boot up. I was wondering why?
i'd guess either the card isn't pushed in all the way, or the card is bad. that's really the only thing i can think of that would make it not show anything. can u hear ur hdd spin up or ram count or anything? if not i'd be worried about ur mobo...
OP
couldn't be the card since it works fine on the other pc i pulled it out from (p2 system) and couldn't be the mobo since i placed the tnt back and it booted up (i'm typing right now from the pc)
