How to offset undervolt without downgrading microcode with B760-I STRIX?

[Primordiarch]

I use offset because manual undervolt causes severe performance loss. But in order to offset, I have to downgrade the microcode. I'm reluctant to do it because it says in the warning "may present security risks".

Please help.

Hi Primordial.
I'd like to help, but I'm just a joe public with a Z790 board.

• Are you able to link something that explains why offset is possible with old microcode but not new?

Please provide more details on specs?

• Which CPU? specifically
• Can you name the Microcode? (I see the B760-I supports 12th and 13th genb chips? Are we talking about a 13th gen and the x1209 microcode?)
  
  

Don't provide a lot of info, at this stage I might not be well placed to help

I won't be able to tell you what to do, but I might be able to look at some material and provide you with an approach to 'judge' yourself. (which I have to say is all anyone should be doing. I've seen far to much 'just add voltage'. literally just that.)

Actually Primorial. I regret I'm not going to be able to help you.
I've just seen yet another one of my posts binned off. (Manually because ASUS doesn't like that I'm making criticisms of their products requesting improvement, or automatically because the Forum software is on a par with their Motherboard software. It doesn't matter which.) But I don't have the time to waste for posts to go missing literally one out of two.

Hi @Primordiarch since you have a STRIX board, your BIOS will default to EZ Mode when you enter into BIOS. You can see this by looking at the bottom right of the screen which will say Advanced Mode (F7). So if you press F7, your BIOS mode will toggle into Advanced options and that same place in bottom right will now say EZ Mode (F7) so that you can press F7 to get back into the default EZ Mode of the BIOS. Basically F7 toggles between the two modes.

Once you are in the ADVANCED MODE, you should be able to set your offset mode as you may have seen on this forum, in some YouTube videos or on other forums over the internet.

I hope this information helps your proceed forward. Good luck!

I will say this though becuase its quick... I 'highly' reccomend you check out using an 'adaptive global' to acheive your undervolt.
V is mapped to different values for different levels of heat and frequency. Its a curve. So just changing V these days can be a far to blunt a tool.
and 'adaptive global' voltage adjusts a far point on the curve, and proportionally adjusts the other points with it.

BUT BE CAREFUL TO CONFIGURE THE RIGHT SIGN
Global Core SVID voltage = adaptive
Offset mode sign = "-"
if you accidentally confire a positive sign you are now adding voltage, and frankly could very easily cook your chip. You can undervolt to your hearts content an not do damage. Not the same the otherway.
Then a voltage = 0.vwxy


I highly recommend you watch all of that video its an extremely good explanation of lots of concepts. But for the love of your silicon, do not blind copy his settings. He knows what he's dong, and that it works for his rig and his needs.

(If your CPU has special P cores, like the 13900 has 16E, 6Performance, and 2 boosted performance, this can be a bitch to test with confidence. In my case I kept e enabled and disabled all but the 2 specials, this allowed headroom for them to full bost while I tested. Then I decided that would have to do. reanabled all the cores and tested all over again.)

(and remember to pause windows updates while making your PC unstable.)

The option "offset voltage" for Global Core become available if I change the microcode to 104 on "Tweaker's Paradise". I believe this is the oldest microcode and also the only microcode available if one wish to change it.

There is offset voltage option for "Actual VRM Core" even without changing the microcode. But if I undervolt from it, it causes severe performance loss.

I'm using 13700KF.

Currently I'm stable with:

• -0.25 global core and -0.11 cache
• ACLL 0.8, DCLL auto
• LLC 4
• PL1=PL2=200W
