So, you have TURBO on I see and HT. If I leave HT off the multiplier stays at 21x and stays at 4.2ghz, no matter the voltage or temperature. If I turn HT on and I put a load of 100% on all the cores, it drops to 20x multi and 4.ghz. The temperature also doesn't matter...

This is normal behavior. Gigabyte boards will not do this I believe as there is a mistake in their implementation of Turbo (i.e., it is always on)...turbo is supposed to be for single threaded apps only. The fact that this is not the case on most boards is a plain mistake in the BIOS (Gigabyte is the worst for it).
