A typical hamburger is about 500 kcal so you would have to go up those stairs 100 times to burn it off in theory.
But science is now saying that burning off calories isn't related to excersise... you burn the same amount doing or not doing physical activity. So I don't know if this is relevant anymore.
Try downclocking the ddr5 memory. If running at 6000 test it at 5600.
