Had 6200-30 locked in on my RAM with 1:1 before this AGESA. I blamed my Asrock motherboard for not overclocking as of 1.3.0.0a so I bought an Asus Crosshair Apex (1dpc) XOC motherboard to see how far I could actually push my RAM with a proper setup and… Whatcha know I can't lock in the settings again.
FCLK will go to 2066 happily. Ram voltages will all be correct. But the RAM will simply not clock up.
Even on all defaults and _only_ changing RAM speed and voltage, it won't clock up. Other timings will stick but not the speed.
Also disabling GDM on all default settings gives me C5 error, even without any other overclock settings being applied.
I _could_ roll back the AGESA and play with that, but I want to know what exactly is going wrong.
