KR7A and PCI dividers??

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 1T 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 above 160FSB??
 
Yes. You are wrong. The KR7A-Raid is just amazing. That is all. the KT266A doesn't support a different divider.
 
I though the probability of corrupting a HDD over 41-42mhz was highly likely. I don't want to toast a drive for 5% of performance.
 
Hey... I've got a KR7A-Raid myself with an athlon 1.6ghz chip. I managed to hit a 145mhz FSB pretty stable @ 1.85vcore, running ~25C idle and 40C load , but nothing like the mentions of the 166+FSB's that i keep hearing about. I too want to know how they are pulling this off without some sort of voltage mod or pci divider for stability.
