Can't overclock my CPU after BIOS update.

[pantsaregood]

Have a 2500K in a Gigabyte GA-Z68A-D3-B3. Ran the UEFI update utility to bring my BIOS up to modern standards, and everything went fine.

The issue, however, is that I can no longer change my Dynamic VCore setting. I can see it in the UEFI menus listed as "Dynamic VCore (DVID) +0.00", but it is greyed out so I can't modify it.

Any ideas to get around this? There isn't any standard VID setting in my BIOS as far as I know.

Gigabyte disabling features that you paid for originally? Time for a class action!

We've seen similar behaviors with earlier-gen processors and BIOS'. It is not something you would ordinarily expect, but as it occurred when I was building a C2Q system with an nVidia chipset, I learned to be a tad more cautious about BIOS updates.

More specifically, I've seen where a BIOS revision was "optimal" for one processor stepping or core design; the motherboard manufacturer had promoted compatibility with a new processor release while requiring a BIOS update; and updating the BIOS made it impossible to overclock the older processor to previously-stable settings.

Before I extend what is "sheer speculation" at this point, I'll give a +1 to Larry's comment . . .

But here's what I suggest. If you were planning to upgrade the processor to Ivy Bridge, then it would seem more practical to "take your chances." If not, I'd stick with a BIOS that precedes any update notes suggesting "compatibility with 3rd generation processors."

Also, someone else with a Z68 chipset -- planning to migrate from SB to IB -- had remarked that he took the caution of updating to each and every later BIOS revision in succession, as opposed to simply flashing the latest version available.

Did you set the vcore to 'normal' before using dvid? Else it wont work.

If it's really broken I think it's time to contact Gigabyte themselves.

There isn't a way to change the CPU VID. I always overclocked by using offsets.

In bios under advanced voltage settings there are 2 settings for controlling vcore. First is CPU Vcore, you have to set this to 'normal'. After doing so you can enter a value for the Dynamic Vcore (DVID) setting. At least that's how it was on my P55 board.

Did you load optimized defaults after the update?

Talking out loud here, but I know that Gigabyte sometimes hides advanced settings until you hit control+F1. However I have only verified that effect on BIOS motherboards, not UEFI. I think it is a pretty well-known Gigabyte thing; it worked on a P4 board from 2002, and on a Core 2 board from 2008.
