Hey DGroves,
thank you for the advice. I followed the first part of your instructions to the letter and I was successful:
- I unplugged the power
- pressed the power button to release residual electricity
- replaced the CPU
- removed the battery
- pressed the CMOS button
Now when I booted up, I still got 8 beeps, but I thought maybe I have to set the BBR jumper back. It worked.
Now I am staring in bewilderment at a BIOS message that tells me I have a BIOS version of M60 v02.48, which is the current version I was trying to install from this link:
https://support.hp.com/de-de/drivers/selfservice/hp-z440-workstation/6978828
I put my Turbo Drive back in and it just booted up my Windows 10 system.
Now...You know what they say, making a mistake falls under experience, twice is just plain stupid...I learned from my mistakes. I am not touching anything anymore right now until I know what to do.
What are my next steps? I guess I could try to update my BIOS from within my OS to make sure it is running correct, right? Will I need to do anything else to install the E5 1680 v3 CPU after that? Are there any steps I have overlooked?
Best regards,
Chris
