![]() A more aggressive fan speed profile would lower the operating temperatures. The difference in average and max fan speeds is low.Max GPU hot spot temp is dangerously close to 90 ☌.The average GPU hot spot temp increases notably, 8.45 ☌, with a +15% power limit.AMD speaks for 315W typical board power, which aligns with the 314.65W average power that I measured with the stock power limit.15% power limit increase in real life is 17.37%.An increase in the power limit heavily affects GPU speeds (with a stock VRAM clock).This is going to be a long ride, so stay with me. I will also use Uniqine Heaven to evaluate the overclock gains (or losses) and check power consumption, GPU and VRAM speeds, temperatures, and many more. Seasonic Prime Titanium 1000 (Cybenetics Titanium)īesides the usual application for full load testing, the power virus called Furmark. I will take it from there and try to understand what is going on because I will use an advanced GPU power analyzer, Powenetics V2 rev 04, which monitors and logs everything with a lower than 1ms polling rate!Ĭorsair Vengeance LPX DDR5 32GB (2 x 16GB) 5200MHz No option overclocks automatically because GPU speeds seriously affect VRAM speeds! This is something that JayTwoCents found out first in this video. Even in auto mode, you can either select GPU auto clocks or VRAM auto. AMD should improve its tuning utility and make it more user-friendly. Also, overclocking is not as easy as it should be because of the min and max sliders AMD uses for GPU speeds and the max slider for VRAM clocks. I soon discovered that you could lose a lot instead of performance gain if you don’t apply the correct settings. The RX 7900 series need attention if you decide to overclock it. Despite the limited time during this period because we are moving to a new country, I found the time for a complete power analysis and a detailed overclocking guide. I finally have the AMD Radeon RX 7900 XT in my hands. I will provide all relevant details in this article, along with a full power analysis which will shed more light to the VRAM lower clocks issue under high GPU speeds. If you don’t dial the correct settings, instead of higher performance, the cards will lose performance, significantly. Overclocking the fresh AMD RX 7900 series GPUs is not as easy as it sounds.
