Hello
I've bought used Z620 with 2 Xeon E5-2609.
It's working fine.
I'm trying an upgrade towards E5-2680.
When i put one cpu, the system start normally.
With second cpu on riser, the computer start then stop immediatly.
And this several time.
So, i put again 2609 cpus : system start without problem.
I took 2660 cpu in another computer and put them in z620 : its start normally.
My question is : dual E5-2680 can't be used ?
regards
