Your motherboard probably does not support that speed, without a bios upgrade.

Download a small utility called CPUID from http://www.cpuid.com or use this direct download link "http://www.cpuid.com/download/hwmonitorpro/HWMonitorPro_106.zip". Using this utility you can analyze your system hardware statistics and also you can find the RAM capacity supported in your system along with various other RAM parameters. It will also show you the available free RAM slots to use, as well. I hope this is useful to you.

Here is the weblink for your model  to update BIOS and Driver. Confirm Version number. You could consider upgradeing  your CPU to one of a faster speed.

You motherboard uses a "Socket A" CPU and therefore has limits to how high you can go.. I would recommend the XP 2200 or 2400+ as a good choice, but you can make your own choice.

hi bajazzo1954,
the cpu would be fast on amd duron pro 2000
it would be better for ur pc

Your M/B support Socket 462 (also called Socket A) is a PGA socket designed for AMD K7 family of processors. This socket can be used with AMD Athlon and Duron processors ranging in speed from 600 MHz to 2200 MHz (3200+) and with bus frequences ranging from 100 MHz to 200 MHz (400 MHz DDR)

Athlon (Socket A) (600 MHz - 1400 MHz)
Athlon XP (1333 MHz - 2333 MHz, or 1500+ - 3200+)
Athlon MP (1000 MHz - 2133 MHz)
Duron (550 MHz - 1800 MHz)
Sempron (socket A) (1500 MHz - 2200 MHz, or 2200+ - 3300+)
Mobile Athlon 4 (850 MHz - 1400 MHz)
Mobile Athlon XP-M (Socket A) (1200 MHz - 2200 MHz, or 1400+ - 3000+)
Mobile Duron (650 MHz - 1200 MHz)

I Recommend to go for Athlon XP with good cooling fan. :)
