hello jaquith, thanks for the answer.
just for review, at my startup bios there`s text above :
E5300 @2,6Ghz 2 CPU CORE...
..a 200mhz system bus procesessor is installed. this processor is not supported on this board and will run at reduced processor clock speed. system performance will be impact.."
now, you give me 2 choice for that problem, exchange the processor cpu, or buy some new mobo that does support with th E5300.
but is there any other opinion for my problem?
btw maybe i think i will choose the first answer,
