Soo !! Sold my Fclk 2233 on and bought another. This one boots 6800 1-1 mode so knew 6600-2200 would be a breeze, spent 2/3 days testing 6600-2200. Was busy for a couple days then got back to trying 2-1 mode which again is just short bursts looking for the ceiling as 8800-2200 CL32 GDM disabled boots on 1st go and the 1st sample that has done so, had another that booted GDM enabled at CL34 but needed some work for it to even train never mind boot, where as this one is just straight auto settings, you’ll never get max boot stable but is usually a good indicator on IMC quality, but so far on short tests 8400-8500 works and 8600 is so so.

Also bear in mind folks, this chip ain’t delidded or messed in anyway, shape or form. I simply keep it stock and use an Arctic 360MM pro, ambient temperature 18/19c
