Does anyone know the maximum safe voltage I can run HBM2 at? I seem to have hit a wall at 1100MHz @ 1050mV. I've risked as high as 1200mV but only managed an unstable 1125MHz on the memory clock. 1100 @ 1050 is rock solid for mining.
Your not changing HBM2 voltage. If your changing memory voltage via wattman your probably not doing anything(if anything your changing VDDCI). Vega's HBM2 voltage is locked at 1.35v for highest state. There is not much headroom to over volt it much more, since they are already over-volting it from the HBM2 spec of 1.2v.
You can't? *You* can't? Watch me.
