I have an Aopen desktop with a AX6BC motherboard with R2.30 bios. It has a Pll 350 processor.
I have flashed the bios to R2.59 which is the latest. Bios R2.41 states support for a Plll 600 processor.
I installed a Plll 450 and it would not work. When I flashed the bios , I went to R2.53 then on to R2.59.
Any ideas why the Plll 450 won't work? Does the latest bios (R2.59) not cover the previous bios versions? I thought Plll 600 support would cover a Plll 450.
Also the Plll 450 has a larger heatsink than the Pll 350, but no fan. Would that pose a problem, if I get the Plll 450 to work?

Thanks

Herman
