Since our favourite tool for the job, MSI Afterburner, doesn’t yet support the card (fair enough), we headed into Radeon WattMan. Starting with a 20 percent power limit increase and a 100MHz core clock increase, we began a benchmark and started logging performance, but nothing changed. Clock speeds, power consumption, fans, performance – everything was roughly the same as before. AMD has since admitted that there’s a bug with settings not sticking, so we had to admit defeat – it wasn’t fixed in time for the review.
AMD did suggest an overclock to us, quoted exactly below:
‘GPU: Undervolting values of ~0.95-1.0V (with increase max power 20-50%) and a frequency increase ~80Mhz (3-5%)’
This suggests that perhaps even AMD isn’t expecting to see much more than a 3-5 percent performance increase, but we’ll have to wait and see until overclocks can be applied manually with more reliability.
We had a modicum of luck with the auto-overclocking functionality in WattMan. After applying this, we ran a benchmark and noticed the fans ramping up as well as a minor 20-30MHz boost to clock speeds, but again we want to hold off reporting any results until we’re more certain things are working properly. The auto memory overclocking, meanwhile, resulted in a crash rather quickly.
