SL 165z HP Proliant Engineer Sample CPU

Hello!

I have a SL 165z Proliant Board with two 6164 HE CPU's running fine.

I got two new CPU's : InterLagos 2.5Ghz 12 Core ES CPU's.

I've installed the latest BIOS, but it says : InterLagos is not supported on this board, shutting down in 15 sec. This is the BIOS. It says it is AMI v4.31 during flash.

There is any hope that someone can help me?

Thanks.
