I have tried all the BIOS versions in the last few months and with the F3h the overclocking performance has improved slightly (very slightly).
Unfortunately they are still too unstable! The VCCSA bug is back, the required voltages are still too high and sometimes the frequencies set on the CPU change by themselves, setting to 4.6 for no reason.
I am currently "stable" @ 4.8Ghz, Vcore 1.245, AVX -1 / AVX512 -2 and the rest of the voltages on AUTO because they didn't bring any improvement (IDLE 28-30°C, Full load 90°C).
Cinebench R23 it gives me an error after about 4 tests, sometimes even after the first test.
Unable to complete any test @ 4.9 and 5 Ghz (I didn't go beyond a 1.36v Vcore).
MacoOS Catalina, Opencore 0.7.4.
Has anyone experienced overclocking on this card recently?
