HP Proliant Gen8 boot failure after bios upgrade and processor upgrade

We have a HP Proliant DL360P with one Intel Xeon e5-2650, and we was in need to use two Xeon e5-2670 V2, this server by default this G8 did not recognizes the v2 processor, so we found this procedure so we did the BIOS Firmware update to most recently (2014) and after we did the processor self-upgrade procedure as described on the link.

Changed the processor and it worked, and after a power-off / power-on it did not booted, in the SID panel it said that the processor was the fault, so we changed back the processor to the e5-2650, and it keept saying that the processor was the fault.

We removed the batery to clear the BIOS and after it botted but appeared a very mess strange characters in the display.

I'm now downloading the Firmware maintenance v10.1 from FTP of HP to make the procedure described here but I want to check with you if with your knowledged if you now something about it

Risky upgrade...

Remove power from the server. Unplug the cables. Let the machine sit for a few minutes. Plug the cables back in and power on.

If this doesn't work, you'll want to reset NVRAM.

Take a look at the HP ProLiant DL360p Gen8 Server Maintenance and Service Guide

You have to clear the CPU errors... Try the sequence detailed here.

If you have physical access to the server, you can try this sequence:

• Remove the power supply units and swap them.

Test to see if the system will boot...

If that doesn't work:

• Remove all power supplies from the chassis
• Locate the System Maintenance Switch on the motherboard - It's a set of 10 DIP switches.
• Turn switch #6 switch on.
• Insert all power supply units.
• Power on the server and allow it to idle for 3 minutes.
• Power the server off.
• Remove all power supplies.
• Return DIP switch #6 to off (original) position.
• Reinsert the power supplies.
• Power the server on.

Test to see if the system will boot...

If that doesn't work:

• Remove all power supplies from the chassis
• Turn DIP switches #1, 5 and 6 switch on.
• Insert all power supply units.
• Power on the server and allow it to idle for 3 minutes.
• Power the server off.
• Remove all power supplies.
• Return DIP switches #1, 5 and 6 to off (original) position.
• Reinsert the power supplies.
• Power the server on.

Test to see if the system will boot...

There's a special firmware update needed to allow the use of E5-2600V2 CPUs in systems originally equipped with V1 CPUs.
