    I recommend r600/r290/r170. maybe add some r1150 to make a r170/r1150 mixture but I would add another stage for it.

    I mounted an old vapoSE on the NB of my maximus formula. gave me a 10mhz fsb boost, but the nb was only -5*C because of bad mounting. Colder might gain some more.

    I tried r1150 in an autocascade but didn't have good results with it. r170 works much better. I think the leap between r290/r507 etc and r1150 is too big.

    with 15% silfos you don't get very nice joints, using flux helps a bit but still not great. using high silver content rods makes it a lot easier and gives much nicer joints.

    casting fins is very very hard. For silver casting the investment must be around 450 *C and the silver may not be above 1100*C else you get casting defects like brittle metal and holes in the metal....

    walt: ron know's what I mean with flooded, we've use that term for years now.
