Thank you for your answers!
in fact, the shop dealer, sell me an Athlon 1800+, when the computer start, i can read in the Bios, that the CPU is an Athlon 1800+, but win XP and differents softwares detect a Duron 1200.
So, i open the processor, and it's a duron 1200 !
the guy sell me a duron 1200, but on my invoice there is an athlon 1800. And the motherboard is not the one i really order to him!
So i call him and he tells me that he will change that to what i ordered !!!!!!
