|"yes it is a 9500"|
The 9500 is one of the "defective" Phenoms, I'm surprised they're even available anymore. The ones with 50 in the model number (9550, 9650, etc) are the fixed versions.
"the board isa geforce 8200"
No, the chipset used on the board is a GeForce 8200. There are dozens of boards that use that chip. If you want my help, I'll need to know the manufacturer (Asus, Biostar, ECS, Gigabyte, MSI, etc) & the model number. Once I get a look at the manual, I'll be able to find what jumper you're talking about. See if you can find it on this list of 13 GeForce 8200 boards:
"socket am2+ 1066 mhz , the ram is 800mhz dual channel ddr2"
Many problems with your description. 1066MHz is max supported RAM speed. Dual channel is a feature of the board, not the RAM & DDR2-800 is the wrong RAM for a Phenom. It will work, but you'll take a performance hit. DDR2-1066 is what you should have gotten.
