Your stock chip has a turbo of 4.7GHz. So when benchmarking, at least one of the cores should already be hitting that and the rest should be close. I'm not sure what the policy is for the new 6-core chips. You should be able to see the stock speed on each core under load using something like the Intel Extreme Tuning Utility.

That said, how are you trying to overclock your chip? When I just jacked up the multiplier across the board (from my stock 4.4 turbo) using the Intel Extreme Tuning Utility, the CPU core voltage was way too high and it kept overheating and thermal throttling, which defeats the purpose of overclocking.

I much had better results when I went into my BIOS and changed the following settings. Note that I have an ASUS Z87 board with a Haswell CPU so your setting will probably be different.

AI Overclock Tuner - XMP
CPU Core Ratio - Sync All Cores
1-Core Ratio Limit - 47
2-Core Ratio Limit - 47
2-Core Ratio Limit - 47
2-Core Ratio Limit - 47
CPU Core Voltage - Adaptive Mode
Additional Turbo Mode Core CPU Voltage - 1.275

I don't know what the correct voltage would be for your CPU but leaving it on "auto" for mine resulted in it being way too high under load.
