AMD artificial limits of clocks speeds, power limit, and voltages are exactly what was holding back these video cards.
As reported in our forums by chispy; Extreme overclock Legend @der8auer proved this by running an unlocked 6900xt Red Devil Ultimate to an insane 3225Mhz on the core on a quick ln2 bench session. Roman took the time to test this and proved what we earlier thought about AMD's decision to lock down these cards so hard limiting the Core and memory clocks as well as a very low power limit impose as well as voltages.
Head on over to youtube @der8auer channel and see the monster WR fastest core clocks ever achieved on a graphics card, 3225Mhz on a quick liquid-nitrogen bench session wish left him wanting more, he will mod the card and add the @elmor evc2 controller to try and reach even higher clocks speed on his next video. He will share the unlocked Bios later and we will check if it can be flash to other 6900xt video cards as there is a new tool that enables flashing the RX 6xxx video cards under windows.
World Record for the fastest Graphics card ever recorded done on a Red Devil Ultimate, 3225Mhz
