Something is not right with the Z97 board and i7-4790 processor. The K version will easily go to 4.2 - 4.4 and even a non k processor should be putting distance between the Ivy Bridge and Haswell combo. Your Ivy Bridge setup sounds like it is running well though.

Ive tried updating the BIOS but still no dice. My Z77-DS3H just works. Ill probably sell the Z97 board and chip to get the cash back i suppose. Yep it runs pretty well no problems at all really its a old trooper :D

I was always under the impression that is how Intel intended Turbo Boost to work, the cores will not be at max Turbo speed when all cores are being boosted. This is why an i7-6700K overclocked to 4.2GHz outperforms a stock i7-6700K which runs at 4GHz and Turbo Boosts up to 4.2GHz.

Also, the i7-3770 should only boost up to 3.9GHz. I don't know why it is able to boost up to 4GHz in the Z97. Maybe there's a bug in the BIOS?

I think Intel does it purposely tbh. Just funny how the 3770 performs better tho. I have tried a BIOS update but same problem. I have also tried the Core i7 4790 in another board which is a H97M-D3H but yet again the CPU is stuck at 3Ghz doesn't even clock down in the H97M-D3H but I've also tried a i3 4360 in both boards and that CPU clocks down. Im not sure what the problem is.
