Who said anything about Slot-1? The adapter I speak of, as you can <A HREF="http://www.compgeeks.com/details.asp?invtid=S370TUA&cat=CPU" target="_new">See Here</A>, is a Socket 370 to Socket 370 adapter. Intel changed a couple pin definitions on their Tualatin processors to make them NOT WORK in older Socket 370 boards. This adapter reassigns those pins to make the CPU work in older boards.
This adapter is very handy because it can do several things:
1.) It can make Tualatin processors work in Coppermine compatable boards like yours.
2.) It can make Coppermine processors work in Mendicino Celeron boards.
3.) It has voltage and bus speed detection pins inside the socket (look closely).
Those pins would be especially handy in your situation for overclocking, because changes in BIOS don't happen until the system boots. So changes at the socket take place imediatly and allow for higher overclocks.
Also (not pertinent to your board), boards older than yours that didn't support Coppermines will with this adapter, but the voltage pins are needed to change the detected voltage to 1.80v. But you don't need that feature on your board.
For your board I suggest a Tualatin Celeron 1100@1466MHz. That's because your board is made for 133MHz bus speeds, and the main performance handicap on Tualatin Celerons is their native 100MHz bus. I'd try it using 1.65v core.
Don't bother emailing Asus because I know more about their boards than they do. Seriously, they don't support adapters and so forth, and rarely retest their boards with higher speed processors. So their knowledge is limited to the technology available way back when your board was a current product.
