I have recently overclocked my Duron 700 to 892 MHZ. I am testing it now.
So far so good. It is currently in the middle of a one week long auto 232 chess
match with my PIII 800Cmine.
Actually overclocking it was easier than I thought it would be. I built the
computer using a Microstar K7T PRO 2-A. this is a good motherboard. The
overclocking can be done directly in he BIOS.
The first thing I had to do was remove the heatsink and chip from the
processor. It was neccessary in order to cross the L1 jumpers on the chip
itself. I didnt feel comfortable doing this with the chip installed!! All that
was needed was an ultrafine #2 pencil and that conducts enough to reconnect the
leads that are factory cut using a laser. I crossed all 4 jumpers. I reinstalled
the chip with some extra thermal coupling paste turned it on and it POSTed fine.
I then went right to CPU core voltage and turned it up .15 VDC. It Posted fine.
then I began using the CPU clock multiplier and went slowly up to 8.5. .... 9.0
would not post. Then I began increasing the bus from the default of 100 up to
105. 106 would POST but it would get kernel errors after being on for more than
15 minutes. i left it at 105 for 24 hours running chess analysis and it seemed
OK. The heatsink was very warm , but not _hot_ to the touch. I could keep my
fingers on it without being burned (thats a good sign).
The CPU itself is only about $60 at TC computers. The athlon 1.2 GHZ is
under $300 and from the latest reports I have seen it working succesfully at
1287 MHZ! I plan on buying an athlon soon and throwing it on my motherboard.The
Microstar supports 1.25 GHZ and 100-130 MHZ bus increments in 1 MHZ increments
as a multiplier.
