Yes. Provided that questions 0x2CDD and 0x2DAD are fixed too, everything’s fine now.
Doing it with FF is like a general rule. So you don’t need to check whether a certain value is within the selectable ones or not.

Yes, QuestionId: 0x2CDD (Cache SVID Voltage) supports only the values [0, 2, 3] (Auto, Offset, Adaptive). QuestionId: 0x2DAD (Switch Microcode) only allows [0, 1] (‘Current microcode’ and ‘Microcode 104’).
Thanks again!
Yeah I can wait until you are able to test it since the computer I’m doing this on is also my main work station, Thanks!
I have an i7-12700KF. I’m trying to undervolt and from the research I have done, and testing with the global svid option you can get a good result without losing too much performance if you put an offset on both the cache and the global. If you change “Actual SVID Voltage” then cinebench scores drop a little more than in half

Thanks for the clarification! I’ll go ahead and try it as well then. I just wanted to undervolt so my 14900K doesn’t overheat, but it’s interesting to learn a bit more along the way. Since my main OS currently is macOS 15, I tried booting Tiny10 to flash the new mod, but it didn’t work.
I’ll give it another shot on Windows 11 later this week, maybe I can try a bootable stick or through a Linux live CD or something.
Sounds good, thanks so much for taking a look. Ill wait until you are able to try it with windows just because I don’t want to take any risks as its hard to get new tech where I live
I tried to flash it using UEFI Interactive Shell v2.2 with FPT.EFI, but I keep getting the same error:
Error 238: The host CPU does not have write access to the target flash area. To enable write access for this operation you must modify the descriptor settings to give host access to this region.
FPT Operation failed.
Strangely, I’m also unable to flash older mods I’ve made. Maybe it’s caused by an automatic update or something? I could use my hardware flasher, but honestly, it’s too much effort right now. Especially since my system is performing well and temperatures are great. I’ll investigate this issue later. You could try flashing it yourself, I’d be surprised if your system didn’t POST, but there is always some risk.
I’ll update you when I have more information.
It’s probably the missing arguments in the command used to fpt flash.

I’ve tried to flash multiple versions, but I still can’t get this to work.
It seems like 6A16A shouldn’t be changed, only 6A1AB, 6A1BB, 6A1DA, 6A1EA, and 6A203. However, no matter what I modify, Offset Mode and Adaptive Mode still stay suppressed.
Does anyone else wants to have a look? Here’s the IFR file: B760-I_IFR-Extract.txt
