Damn, you was right, i've done 2-3 test with your configuration. The vtt was too high, now i'ts 1.24v and vcore is 1.23v. OCCT is running by 15 mins :eek:
Why nobody has never talked about this vcore problem before?
PS: I'll post the screen after this test.
Here it is. (i've stopped the test manually) vtt is 1.26v
