I run 4.66 daily with my cryorig r1 ultimate. I've hit 5.3 stable for one run through heaven, but it was hot as hell. With my fans locked at 50% my cpu never goes past 60 OC'd, I'm quite happy with that.
I managed to do a bit of overclocking last weekend but I could not get it to be stable. I think I need to get a better Mobo. Just funds will not allow at the moment. I think I should match my memory as well looks like I bought different 8gb sticks >___>
4.6 all core stable under 50c. Was good but unstable I could pull of 2-3 hours of heavy gaming, I coulda done better if I had more aggressive LLC and power settings. I think I hit 4.8 but it was 4 cores only and I only ran it to see if I could boot and didn't think much of it since it's only 4 cores.
