FSB divider questions?? Abit KR7A-Raid133 or anyone else too!!

[JustStarting]

I've got my new KR7A-Raid133 up and running stable for the last week at default clock speeds (XP1700+/11*133FSB). Memory is running CAS2/4Way/2T/5T/2T/Auto/Auto/2Tcommand/HI/0-ps. I have not gone 1T Command rate yet- I'm waiting for my 2nd stick of Crucial and will probably run it 2T anyway with 2 sticks. Seems to be very stable with DDR set @2.75v. I plan on FSB OC'ing a little, and wonder how these things have been seen to get up to 160-180FSB with a divider of 4:2:1?? The PCI bus would run out of spec wouldn't it?? At 160FSB PCI bus is 40mhz- at 180 PCI bus is 45. No way anyone is running a hdd at 45mhz PCI bus. Am I wrong here? Does this mean there is a 1/5 divider that does not show up in the Bios?




Who has one of these Screamers running over 150-160 FSB? Please post your RAM settings and Voltages (I/O, DDR).

unlock the multiplier and change that--that is always safer for your system anyways. i don't like FSB OC myself...

my kr7a-r can run stable at fsb 145,
i can run it fsb 152 but eventually it will crash on windows
more than that, it can boot but cannot go into windows[win xp pro]

i try it with just vga card running i can push it w/ fsb 150 run and stable

i believe it's all due to divider 4 on the pci, if just
it has divider5 than it will be 150/5=30 it probably will run smoothly

but you probably will have better luck than me with your system and
you can push it trough fsb 160 or even 180

I totally agree with that
