anyone intimately familiar with Gigabyte X58A-UD5 BIOS for i7 OCing?

I have my system 99.9% stable for 24/7 gaming/surfing/multimedia/vent server/word processing/etc

but, it did crash today. I'm not sure which voltage to raise. the CPU dynamic vcore is already 1.39v under load and the QPI/VTT is 1.47v already. I can't run any lower. Should I be messing with the IOH core or QPI PLL or ??

I have that board, but with a 980 CPU. In your case I'd try playing with CPU PLL. It should be 1.8V stock. Some say raising it helps, others that lowering it helps. In my case it was lowering to 1.6V that fixed random hiccups and allowed to also lower QPI/VTT. But don't take my word for it - I just found this on some random forum. It may actually be harmful.

That sounds high to me! Why do you use Dynamic Vcore?

Anyway if you run 1600MHz sticks in 1850MHz i bet thats your problem maybe?
Also read this awesome guide and start from the beginning instead.

I assume you have X8 SPD right? What happens if you step back to X6 and adjust the uncore frequency? Just to check if the mem sticks is involved in this issue.

I couldnt run above 1600MHz with my cossy,s .May be something i did wrong but Corsair wont give their word that 1600MHz sticks will work above spec

I have Corsair 2000MHz C9 4GB modules (3 of them). Dynamic vcore is used when you want to use Intel speed step and the other power saving features.

And that guide is the exact one I used this time. I have a better one in my bookmarks, but that one is OK...

and no, the RAM is on 10x right now. I'm running a 185 Bclk.

BTW, I found this article (I LOVE IT!!!!) that describes all the voltages for X58: http://www.techpowerup.com/forums/threads/overclocking-the-x58-a-practical-guide.108526/
