hi guys I have the above Mac Pro with a single CPU
I upgraded it to a dual tray board but for some reason it won't boot it at all
I get normal fan speed and that's it no chime no video no nothing power light is solid
I have removed both heatsinks and inspected the CPU's And Sockets and all looks good.
now to trouble shoot I tried just CPU A in the board and the Mac Pro fired up and chimed booted see's the CPU tray serial and SMC version.
so I thought great placed back in CPU B and no chime again,
just normal fan spin and power light solid
any advice guys ?
my only other question is could it be that the CPU board wasn't upgraded to a 5,1 firmware ?
despite it working with a single CPU in socket a ?
any help is appreciated thanks
