Managed to get a E5-2609 v3, the system booted and update all system to latest version bios/bmc/me etc.
After changing to E5-2630L v3 ES the system posts that it initialized chipset and memory with no error and hangs like this with a blinking cursor at the bottom. The diagnostic codes show (Orange 0100 / Green 1111).
I think I am missing smth or the CPUs are bad or they are not compatible...
well those ES chips did not work for me so i returned them...money was returned asap . I suspect a CPU issue but cant be sure since i dont use any other ES samples, I use retail 2609 v4 Xeons (after a Bios update with a v3) in a 2 node vsphere cluster.
Well, i will never suggest anyone to ever use ES cpu's again, eventhough i never found any processor to not be working in this machine. You guys must've had quite the frustration to get these servers to work as well. Hope you are happy with the server now though~!
Also, thanks Rand_ for helping these people out with your information, saved me from losing a bit of hair i think.
