So I just finished building a new rig my friend. Its got an i5-4690k and a Gigabyte GA-B85M-DS3H-A. Once we did some stress testing to make sure everything was working we started on an overclock. Now ive done overclock before on my FX-6300 and on a gigabyte board so I know a little bit about overclocking. I turned the turboboost off, put the multiplier to 42 set the voltage to 1.2 for a safe base setting. We boot up the computer and start up Battlefront to stress the CPU. I open CPU-Z and the clock speed is jumping around and it is only going up to about 3.8GHZ. So we went back into the BIOS and turned off all of the C states but to still to no avail. I also tried just setting everything to stock and setting the Turboboost multiplier higher but again with no success. The next logical step would be see if the BIOS needed an update, it doesn't.
But here is where my second question starts. There is another board called the GA-B85M-DS3H, note the missing A on the end. The two boards look identical and have the same specifications. Its most recent BIOS update is newer than the one for the A version and is about 2x bigger. A revision before that also says it has better K-sku performance.
Okay so now for the real questions.
Thank you for helping out!!!

What settings could I be missing that is preventing the overclock?
What does that A on the end of the name represent(ive looked everywhere with no success)?
And would it be safe to use the non A's newer BIOS to try on our board?
