Radeon R9 Fury X voltage scaling results are underwhelming
by from Techreport on (#FMA3)
TechPowerUp's "W1zzard", who makes the wonderful and ubiquitous GPU-Z software, has taken it upon himself to overclock AMD's R9 Fury X card and report back on its voltage scaling. He accomplished this feat after struggling to add Fury X voltage monitoring and controls to GPU-Z, which he describes as no easy task.
The card was first tested at its 500-MHz stock memory clock, with stock fan speeds. The power limit was set at +50% to avoid throttling. Battlefield 3 was the testing title of choice, running at 4K resolution. W1zzard worked upward in 24 mV steps from stock, recording the maximum stable GPU clock speed at each step. He eventually found ...
