How to unlock multiplier on QDE4 and B85? Microcodes mod?

I read this topic

And people on Xeons can mod their bioses to change multipliers to maximum on 4 cores.

My problem is that i have QDE4 engineering sample and it is 4770K.

But my motherboard Gigabyte B85 D3H v1.0/1.1 is blocking to overclock it and i can only force max turbo. I can't even change voltage.

Default clock is 2800Mhz and i can force it to 3200Mhz on all cores.

Can anyone help? Maybe we can change microcodes or something.

I tried flashing older bioses but with no profit.

This is my CPU-Z report:
