Here are 2 links from the 2 reviewers:
Hardocp.com
Templintech.com
I am going to quote on templintech:
<< The KR7A non-raid board I have will hit 190mhz FSb easily >>
And then one from hardocp:
<< We were surprised at the bus speed on this board as we were hoping to reach a smooth 166MHz (although the PCI bus would be torqued to hell). We did drop the multiplier to its lowest and still cracking the 150FSB mark was not possible for us. >>
What do you think? I am aware that different week production might result in different yield. But I didnt expect the difference to be > 40 MHz on the FSB.
