Yeah...it should be higher. So you can either trust what Valley says it is during then benchmark. Or run GPU-Z in the background and see what it says. It'll record whatever the max boost clock is, so you can check it afterwards. Just click the GPU-Z Sensors tab right after Valley's done running and then click the down pointing v to the right of GPU Core Clock. Then check Show Highest Reading. It'll show you the max boost speed achieved since GPU-Z was opened. So don't open it until right before you run the benchmark. And be sure to check it before you run any other benchmarks, games, etc..
