Unlocking is not always going to work for every single chip. You should not expect to even unlock the extra cores...it's extra gravy if you do, and even more so if they overclock well. If that core is failing, try using the Intel Burn Test, too. Chances are your vcore is too low, the CPU core is too low, and should be disabled, or the chip simply won't run it.
Core 3 managed 4 hours before failing prime, also done 5 cycles of IBT (not tried more yet). It doesn't crash in games or anything else but I want 10 hours prime stable. Previous owner ran all 4 cores at 4.2GHz with 1.44v 24/7 with water cooling, I'm using a TRUE with quiet noctua fans so want the voltage as low as possible:





Other boards have an advanced clock calibration (ACC) option that the ud5 seems to be lacking, maybe it is in a different bios? Also in AOD multipliers can be set differently for individual cores, it would be nice to see this option in the bios rather than relying on software.

ACC is no good to overclock. Just use Turbo but disable cool n quiet. I got 4.5GHz under water on a 980.

I think only X6s support turbo (maybe some 9xxT have it but not seen them in the wild). CnQ is still good to use if your cpu is happy at the lower frequencies and voltages CnQ chooses at low loads, saves leccy and lowers idle heat and noise..

From what I've read each core should have an optimum ACC level, thought it might be interesting to play around with but it just seems to missing all together.

The only quad core with Turbo is the 960T, that's on sale from yesterday.

The 990 looks pretty sweet. Thank god gigabyte got their head out of their butt and decided to support nvidia sli. I wont have to use the sli hack anymore! Does anyone know if the 990 will be any more benificial for my x6 1090t bandwidth wise?

i wonder how many owners of rev 2.x boards is willing to purchase another gigabyte product because they didn't release a bios update when the other vendors have? Heck, a lower end model has a bios update too but not this one.

Personally, i'm looking at asus right now just because it looks like they are at least supporting their older product lines.

I just built a new computer with Crosshair V and a AMD 1100t. I am waiting for bulldozer to upgrade CPU. Gigabyte lost my future business. A simple BIOS that others are doing and Gigabyte believes more in making money than customer service. ASUS is on the ball. This Crosshair V Formula rocks!

i'm still wondering if they will have a bios update or not. The ud7 got one, and a bunch of older mobos also got one so who knows...

It's just that they already said they won't so... who knows..
