I thought I'd start this thread for members who have updated their BIOS to the latest 1502 and use the AI OC feature in the UEFI to OC their Maximus XI mobos.
I found with BIOS 1401 AI OCing gave a 22% OC with 48 and 50 CPU multiplier for no load and under load respectively.
BIOS 1502 has increased the AI OC to 27% with a 50 and 51 CPU multiplier for no load and under load setting. It would be interesting to see what other members found when going from BIOS 1401 to 1502 using AI OC feature in the UEFI.
