Question MSI Z490 Mag Tomahawk Turbo Ratio

Hi guys,

Anyone have any experience setting Turbo Ratio's for the Z490 Mag Tomahawk. My current ratio's are:
Group 1 - 3 core's = 50
Group 2 - 4 to 10 cores = 45

My CPU is a i9 10850K. I've changed the turbo mode from 'All Core' to 'Turbo Ratio' to set the groups above, I've also set a negative vcore offset of -0.095v. Otherwise everything else is on auto. The CPU never boosts beyond 4.5Ghz, I've also tried it with stock frequencies and it will boost to 4.8Ghz but it will never go higher when using Turbo Ratio. It will hit higher single core frequencies when using the default 'All Core' turbo setting.

Thanks
