For our manual overclocking tests, we used MSI Afterburner. Our best results are as below.
Our overclock added exactly 110MHz to the AMP Extreme Holo's average operating frequency.
In game, this overclocked resulted in frame rate improvements of between 5-9%, which is pretty typical of Ampere as a whole.
Power draw meanwhile, increased to 458W – about a 10% bump over stock.
