I have a Asus Z8NA-D6 motherboard. Been running fine so far with one E5504 Xeon processor.

I have added another Xeon E5504 CPU to the second slot and it will not power up (or there is no signal to the monitor).

The status lights turn on as normal. no error led.

Nothing happens other then the leds start and both cpus/fans power up. HDD power up.

I tried clearing CMOS.

Any sugestions?

Update. Removing ram for second cpu makes it boot atleast. itboots with memory pluged in for cpu 1. (2 4gb modules) when addin one more to the second cpu it still boots but bios only see the 2 blocks at cpu 1)
