The best bet may be Crucial CAS2 PC133 set at CAS3. Another forum member (Insane3D) is running it at 166 in his KK266-R with memory benchmarks matching some DDR systems.
I have tried sticks of Mushkin, Mosel Vitelic, Crucial, and Infineon in my A7V133, and found that a mix of Crucial CAS2 PC133, and Infineon does the best for me. I am currently running it at 3-2-2 at an FSB of 158. The Sandra 2001 memory benchmarks come in at 624/711. It has taken everything I could throw at it for the last couple of days without crashing, and very stable even with USB devices and the soundcard.
