I bought a Galax Gtx 1070 ti ex. On stock settings, I get 1836Mhz core clocks and the max overclock I achieved at 100% fan was 1911 Mhz on the core and 420Mhz on the memory with stock voltage. I get 1949 max core overclock when 100% voltage is added . I use an Antec VP650P. Are these comparatively low clocks a result of a poor silicon lottery or my PSU? Temperatures under 100% load reach 76 degrees.
