Question 7900X Overclocking problem

[cassiopei1337]

Hey folks,
I'm an owner of a 7900X for a year already and it was running at 4900 @ 1.265v all days long absolutely normal. A few days ago I updated my old BIOS to a newer one and from this point I can't overclock my CPU anymore at all - it runs normal at 4500 @ 1.13v, but f.e. it crashes at heavy CPU load even at 4800 @ 1.225v. My previous settings (4.9 @ 1.265) also crasehs my PC. And those crashes are pretty weird - no blue screen, just a turn off.
My MoBo is AORUS Gaming 3 X299. If that is important, RAM is Corsair Vengeance LPX 4x16GB @ 3600 (overclocked to 3800 with no seemed problems).

Any ideas and tips to solve this? I tried to roll back to my old bios - no success. Monitoring CPU temp just a second before PC crashes shows me something around 65c, which isn't bad for this CPU at all.
The only thing I can think of is something in my bios settings - so maybe someone owning the same CPU\MoBo can share some important settings I could've forget about.
Thanks in advance.


PS And my PSU is Be quiet Dark Power Pro 1000W 80 plat.

For those who may encounter the same problem - I changed the TDP (Watts) in BIOS from 140 to 200. Now it works just fine with my old settings.
