Did I fry my CPU?

[PChiu]

I am new to overclocking, but I am worried I damaged my cpu. I have an asus Z790 extreme motherboard with a 14900k cpu. Initially I used the AI-Optimization feature to get the overclock up to 6.1Ghz. All was good.

After a few days, the computer started crashing and so I used "Auto" (I guess this means to let the bios work out what would be a good clock speed for the processor). It came up with 6.0Ghz, and I was happy with that as well... then a few days go by again and that becomes unstable.

In my infinite stupidity, I decided to start playing with the DIGI+ VRM settings. It turns outs that if I set "CPU Load-line calibration" to "Level 8" I was able to make it stable again... after a while, it became unstable again... and on the same path of stupidity, i started playing with the V/F curve.

Originally, at 6.0Ghz, the 14900k would be supplied 1.503V, I found out through trial and error that if I gave it an extra 0.2V (1.703V) that it would run stable.... and for a while it did... but I would disturbingly run at 1.7V the whole time and won't clock down at all even at idle.

But now, 10 days in... it won't run stable no matter what I do. This is the second processor that has done something like that. The first one... I set my threshold temp at 115C and I think I burned that one.... this one never ran over 100C.

Did I let it have too much voltage and resulted in frying my cpu again? I am not sure what to do... I thought the max voltage was 1.72V and it had overvoltage protection.... (I didn't play with those settings).... help!

I guess... I should have done a whole lot more reading before I decided to play with options in the bios...

The TJMAX for these cpu's is 100 C, you going over that will probably cause damage. I would go to bios defaults and then set the P-core ratios ex (55) = 5.5GHZ. You can also set specific P-core ratios on which core has the best single core clocks with an *.
