of those 3 Infineon all the way.
I had a 256mb stick of Pc2100 Infineon that did 205FSB, infineon is good stuff, but the other stuff is not bad either, seems like 175 or more FSB is possible with any of the chips.
But don't get the Spectek ships if you can avoid them, I had 7 sticks of the Spectek stuff and none were completely stable on any AMD rig I tried, and I tried lots.
I stuck 4 sticks of the PC2700 spectek chips in a IS7-E and it ran flawlessly, so I guess they just don't like AMD chipsets.
