Overclocking
Keeping it simple, we increased the all-core frequency in conjunction with voltage at 1.4V. The upshot? A stable 3.95GHz across the eight threads. The IGP, meanwhile, clocked up from a default 1.4GHz to 1.45GHz. And appreciating the sensitivity of onboard graphics to system memory speeds, the modules were run at DDR4-3200 CL14-14-14.
Not huge gains, because AMD runs pretty close to the wire with respect to out-of-the-box frequencies.
