The “About This Mac…” and System Profiler would insist that the CPU was running at 2 GHz. GeekBench also reported a 2 GHz CPU but under the final results, the CPU was listed as running at 1.86 GHz

We then removed the SMBIOS patch, flushed the cache, and rebooted. This time, the CPU was correctly running at 2.0GHz in CPU-X and GeekBench. The benchmarks were unchanged. Our Hacked Mac on a Mac was running about 18% slower for CPU tests, and 17% slower on GPU tests.
