I built a system with a P8Z68-V PRO and Core i5-2500K yesterday. After building it, I entered the BIOS menu and Loaded Optimized Defaults.
I then had an issue with the system powering on/off multiple times each time it was turned on from a cold start. It would say boot up and say "Overclock Failed". It turns out the "Optimized Defaults" were applying an overclock: BCLK set to 104, and multiplier set to 42. Not sure why the defaults were doing this, but I just left it alone for the moment.
I then installed Windows 7 and downloaded the latest 0501 BIOS. I went into the BIOS menu and updated the BIOS. The system continued doing the multiple reboots. After updating the BIOS, I manually set the BCLK to 100, and multiplier to 34, and the system now boots successfully.
So I think I made a couple of mistakes:
* I downloaded and updated the BIOS while the system was not completely stable
* I did not reset the CMOS before updating the BIOS, as I have read is recommended by a few forum posts.
A couple of questions:
1) Have I messed up my system? Should I reupdate the BIOS?
2) How would I know if a BIOS update failed? Would it be pretty obvious that there were problems with the system?
Thanks in advance!
