couldnt find a map

No jumper change.

Just populate the RAM sockets. If possible, do not mix DIMM's.

thanks for your help.
I have tried this first. doesnt work. it still recognise the original (black) 2 RAM (256 each) but not the 2 new (512 each) (blue) slots.
I was not able to verify exactly the version of the MoBo.
what can be done ?
