I have 2 sticks of SDRAM133 which won't run reliably at CAS2.
At what fsb should I try to run them at CAS3 to get the same performance as 133/CAS2?

In my experience... at cas2@100fsb I get the same performance (give or take 10 megs per second) as cas3@133fsb... so I'd assume you'd need to up the fsb to like 166 or so to get even close... I could be wrong so don't quote me

I suspect if the RAM has problems delivering performance at 133CL2 it would also have problem delivering the same performance at CL3 higher speed.

My secomnd rigs mem runs @ 148Mhz Cas3 but won't run at 133 Cas2, I suspect it will run at 100@cas2, and by upping FSB to 112 would it be faster than the mem at 148Mhz cas3??

the cpu of the second rig will run better under 148mhz
