I'm very stable right now at 6400, 1:1 mode, 2133 FCLK. Before I start tightening my timings, i was going to try and get gear down mode disabled working but I can't seem to find the right voltages.
I tried increasing VDDIO to 1.40v and I also tried increasing VDDP to 1.05 and 1.1 but that didn't work either.
Is there anything else I should try or just call it a day and start tightening my timings?
