Sun e250 Processor Upgrade

Please help...

I have a Sun e250 with 2x 300mhz processors in it with a serial console. All is fine with this setup. I have two 400mhz processors to put into this server, but when I power this server on with the two 400 mhz processors installed, I just get a bunch of garbled text as below... The server does not ever display the openboot prompt or attempt to boot. I took one of each of the 400mhz processors, and installed one at time to see if I got the same results, and I sure did. I was thinking that maybe one of them is bad. Is both of the processors bad, or am I just missing something? The 400mhz processors have different revision numbers. Does that matter? Also below is the white label numbers off of the 400mhz processors. FYI, the serial console works perfectly with the 300mhz procs installed.

proc #15445-04 Rev 50

proce #25445-03 Rev 51

Openboot: 3.12
