So I've tried to overclock my FCLK at 2200 and I've stresstested by using Linpack Xtreme 10Gb 100 pass. Unless I'm mistaken, it looks like stable ?
And also what do you think about the timings & voltages used ? (I use the VDD-VDDQ values from the EXPO profiles / M_Ordering set at "Normal" – stable 24h VT-3 & TM5 Ryzen3D-1usmus & HCi).
