In the end, a much less aggressive overclock was completely secure, however I’m not skilled sufficient to know finest strategy overclocking these 40 Sequence GPUs. It was fairly fascinating to see, in particular person, simply how a lot of an influence penalty was incurred when growing the voltage. By default that is, just like the Founders Version, a 320 W TBP card. Rising energy to 125% and voltage to +50, nevertheless, noticed board energy rise to 374.4 W, with 300.4 W chip energy throughout a profitable 3DMark Pace Means run.
I’m curious to see how extra competent individuals than myself fare in overclocking the RTX 4080, and for an air-cooled design there may be loads of thermal headroom accessible from the SUPRIM X design – to not point out energy and voltage. I’m simply the mistaken particular person to check this. On the plus aspect, even when overclocked I noticed a modest 65.6 C core, 77.9 C sizzling spot (in a cool 17 C room) with the default profile (max 50% followers underneath load). It’s a very large cooler, and should you crank up the followers there may be extra thermal headroom than you might be ever prone to want.
Another factor: as I briefly talked about above, MSI affords an “Excessive Efficiency” mode by way of their MSI Middle software program, which takes Increase as much as 2640 MHz (an additional 15 MHz). Contemplating the very modest enchancment I achieved from handbook overclocking, the “Excessive Efficiency” mode would have a minimal influence on efficiency, however should you MSI Middle put in anyway it might probably’t damage.
