Therefore, this overclock of 2115MHz is 240MHz higher or 13% over a default stock Founders Edition. Also, consider the reference spec is 1770MHz, and on our Founders Edition, it operated at 1875MHz. At 2115MHz this overclock is roughly 180MHz higher than the default, or a 9% overclock, which is respectable. With this overclock the new clock speed starts out high at 2130MHz but then settles over time down to around 2115MHz. At default, the clock speed settled around 1935MHz. In the graph above you can see that this overclock is well exceeding the default clock speed. On that card memory overclock was 20GHz and GPU was at +130 of its 1770MHz GPU Boost. This is a higher overclock on both GPU and memory than we experienced with the Founders Edition video card. In addition, we managed to push the memory up to +1000 which sets it at 1313MHz (21GHz) versus the default 1188MHz (19GHz.) This pushes the memory bandwidth up to 672GB/s versus the default 608GB/s. This puts the new “Boost” clock at 2020MHz versus the default 1860MHz.

The highest overclock we found on this video card was with the Core Clock up at +160. In the end, we left Voltage alone, and let GPU Boost manage it. Otherwise, we could increase the fan speed as needed and we had control over Core Voltage. Still, a nice 10% bump would have been nice. When we overclocked the Founders Edition, we could take it up by 10%, but of course, the MSI video card most likely runs with higher power table limits already for the factory overclock to work. This gives us a little headroom, but not much. In MSI Afterburner we can increase the Power Limit on this video card by just 6% taking it from 100% to 106%.
