Billyjack, how are you getting 1.4GHz? By upping the FSB? I haven't tried upping the FSB, with the new chip, yet. With my 800@900 I could only go to 103MHz, but Prime95 would burp so I backed it down to 100MHz. I think that's because I bought generic RAM back when PC133 was almost $200 for a 256MB stick.
Budman, I've had this KT7-RAID since October of last year. Once I figured how to work around it's little quirks, it's run pretty stable. Might get a lockup during startup about once a month (which is about the same as my ASUS/Intel setup at work).
I did buy this chip with the plan to move it to a Palimino certified motherboard, after the second revision of the board. Then wait for the Palimino to drop in price (1.7 or 1.8GHz for less than $150). In the mean time I'm wasting it's potential(it's a 1200C) on this old 200MHz FSB motherboard.
