bought 2 with Duron 1.8
Neither one will go thru POST.
No stray mounting grounds.
Power supply shows proper voltages on all leads including
the two status lines.

The ASUS literature doesn't mention Duron compatibility, but
you'd think Tigerdirect wouldn't mismatch items, would they?

anyone got a suggestion?
thanks / mark

Duron is listed:

http://support.asus.com.tw/cpusuppo...?type=1&name=A7S8X-MX&SLanguage=en-us&cache=1

Set FSB_SEL jumpers to a lower frequency. Is it 133MHz for Duron?
If it still won't post, try 100MHz and see if that helps.
Section 1.9 "Jumpers" in manual, item #3 has details for FSB_SEL.

Duron spec - 133 Mhz is mentioned. For the 1800 Duron, the
multiplier is screwed. The four bit code on this unit, stops
at 12.5x. How will the hardware represent a 13.5x multiplier ?
You will need 13.5 x 133 to reach 1800Mhz, I think.

Good luck,

Thanks, Paul - the links shed some light on compatibility. But
still no beep of any kind, however, at any fsb speed. (The board
was jumpered to 100, rather than the factory default 166, so
perhaps at least that issue has arisen before...)

Can you get your hands on another type of Athlon ?

Perhaps it needs a different BIOS flashed to it.
The latest revision is 1007.

Phone Asus tech support and see if this is a known
issue.
