Either one should work. I used manual because I had my manual overclock all figured out. Your VID should be somewhere in the 1.2xx range.

Bgineng, thank you so much for all the advice. I'll update y'all tomorrow how it went. Thanks to everyone else who has chimed in as well!

I wish more information about offset voltage using the new gigabyte boards was available. It does not work like all the others. To adjust the Dynamic VID voltage you must set the vcore to "normal" and it will lock in 1.105 vcore for me. Then the offset can be set to add to that vcore. At least this is how I understand it to operate. Anybody have some experience or knowledge on using DVID vcore adjustments on the UD5H? From what I can tell these adjustments work different then the Asus offset ect maybe even work better. Please don't respond guessing what it means I only want somebody that USES the board and DVID to reply to me thanks.

When using an offset you can think of LLC as the range between idle vcore and load vcore, while the offset value is what shifts that range.

It's the same on all these boards and processors (P67, Z68, Z77 and SB, IB).

For the minimum idle consumption possible:

Set your clock speed, leave offset at Auto or 0.000v (+/- 0.005 for ASUS), raise LLC until you are stable, then lower offset until you've found your minimum vcore for that speed.

If you think a fixed vcore seems more stable than dynamic/offset, then you might just have too large a gap between idle and load vcore. Increase whatever "voltage response" settings you've got, as well as phase options. If that doesn't help, then lower LLC and raise offset to close the gap between idle and load voltage.

Ok, so I'm getting much closer! I've got the LLC at 75%, the offset to (-) .015, my DRAM voltage at 1.60, PLL at 1.6. When I run Prime95, it crashes but doesn't BSOD. So I'm trying to figure out what I need to change. My VID is 1.24. Using that offset puts me at about 1.224 VCore at full load with a 45x multiplier. I was running the Prime95 custom blend with 12GB of ram and 10 min intervals. Should I raise my VCore? Is it my RAM? I ran Memtest86 for about 8 hours and it passed with no errors. Ideas would be greatly appreciated!

Sounds like you just need to bump up the Vcore a little bit more. How long did prime run before crashing?

Roughly an hour? I'm just hoping it's not the RAM because I have no idea how to OC that yet. I'll try reducing the negative offset by .005 and see how that fares.

I ran an OCCT test before at 90% RAM with AVX, but for only 5 mins. It passed though. Let me try upping the VCore some and see how that works.

If you passed 8 hours of memtest your ram is probably fine. This sounds like the same problem I have when my Vcore is slightly too low.

Well, Prime95 failed again at 1.232v. I did a custom blend of 10 mins intervals and 12GB of ram. I'm running a Prime95 test right now at stock to make sure it's not my chip. Once I rule that out, it either has to be the motherboard or the RAM. The only reason I'm leaning towards RAM, is when I restarted it this morning, the red light next to the RAM came on and stayed on. I had to use the MemOk! button to reset the RAM settings. For some reason, my motherboard wants to put it at 1333MHz. But, I just don't see how my chip could fail 4.5 at 1.232v when people are hitting that with 1.19-1.22v.

Are you using an XMP profile for your ram or are you setting stuff manually?
