Are you saying the higher the normal gpu temp the higher the memory temp? I don't believe that pal just because you are running under 60°C temp doesn't mean your memory temp isn't high
Uh, yes. Do you not understand how fan speeds and GPU heat dissipation works...pal? My particular card has the same excellent cooler as the 3080/90 version of the Ultra XC3, and the 3070 uses a lot less power to begin with. On my Sapphire Pulse 5700XT that I have running in another system, I can see the memory temp. When I reduce the card temp with increased fan speed/open air ventilation, the memory temp drops right away. I dropped it from 94C to a constant 80C now at 39% fan speed (the Pulse has large fans). This is simple thermodynamics.
Do you seriously believe that there's no benefit going from 60C to 44C card temp on the memory
Go ahead and run it at 60C and see how long the card lasts. I'm not taking stupid chances like that for 3 reasons: what I paid for it ($629USD), how hard it is to get another card, and the fact that the 30 series is new and nobody has ANY long-term data on how they perform, other than to know that the 3080/90 throttle because of high GDDR6X memory temps (not the same memory as the 3070).
