How to unlock multiplier and Turbo on QDE4 and B85?

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.

It’s highly likely your issues are due to the nature of that engineering sample, it’s unlikely you’ll be able to make any progress on that particular board or possibly any board for that matter.

It's not true. QDE4 is overclockable but not on my board and not on my bios. We need to change something to can overclock
