Wow... I've never managed to get my 060 on my BPPC past 60Mhz, even with a fan attached to it if i stick a 64Mhz crystal in all I get Is a yellow screen... 
(never attempted to overclock the PPC side though, not sure if it can be done and don't fancy knackering nearly 500 quids worth of kit...)
We meet again!
I'm hopefully sending my Card to Stachu early next year for an upgrade to 330mhz PPC and maybe a little boost on the 060 as well.
By the way, what you describe I bet its the Memory that cannot run at the speed you were trying I think this is why Stachu uses 50ns Simms
