I had 2 diferent series of those chips.

I had 2 diferent series of those chips. From 2 diferent suppliers. I put some of chips from both series on other mobos and they ware working.
Mikkey, It`s good idea to put back old one. I`ll reball it and put it back.
Rom, there is no post codes becouse mobo is dead.
I think, if chips were good, that some of capacitors were bad and wait for me to heat mobo and then die. I searced for them but none found bad.
