I can't rise the memory voltage above 1.435 although for the last 3 bios releases it states that they add memory voltage options over 1.435V. Once I set it to 1.45v it wont post anymore. How do you set it to 1.5v ? Maybe I didn't do it from the right place (first time I have a Gigabyte board)...
Yes, weird behavior. Its only happens in gaming. On desktop environment it boost properly with loads that exceed 10% but in games that barely use 10% is just caped at 5.5. (X670E AORUS MASTER - AGESA 1.0.0.3 A)
Is not the boost, is the latency penalty between CCDs. My 7950x is locked on all cores at 5.5 on all games and exhibits the same behavior when you set the affinity on just one CCD. For example on Riftbreaker the difference is ~30 fps. Other games respond well with affinity on physical cores...
