@xiaox - Adding microcode does not always = adding CPU compatibility. When you are forced to remove a microcode due to need more space or something, replace/remove an older one you don't use/need, always leave in place the ones for your own old and new CPU.
Please tell me your old CPU model and your new CPU model, and link me to the BIOS version you are using, and I will update microcodes for you and make sure both stay in place for old and new CPU.

I mean I want to add cpu support for my bios, then i readed this topic and used ubu, but they were use new microcode to replace the olds, i want to know how to add not add for me

I think i am figured it out, now i already flashed the moded bios with both different microcode and updated vbois, gop vbt, gop driver and nvmexpressdxe4, but my new cpu is sitll on the way

Hello, I am new here and I need help, I have a Lenovo g550 laptop with pm45 chipset and I have a qx9300 processor that I want to put in it, but when I install it in its p478 socket, it does not let me access the bios, it does not start windows and the screen goes black, after a minute turns off.
My question is the following, if I modified the 1067A microcode, would it work?
In the specifications of the pm45 chipset it says that it is compatible, at present I have a core2 duo t4200 at 35w the qx9300 goes at 45w, this would not be much of a problem right?
Thank you very much for your help.

@Lost_N_BIOS can u help to understand how can work a bios without cpu micrcode? read the guide: ME Patches and performance:

@pipes80 - The only series I've seen/heard of that working on is X99, like this, and microcode is then ideally loaded in OS
I've seen a few people try other series, and usually = brick, can't even boot to BIOS. Cool to see this working now on Z490 too!
Does not look ideal for non-super-overclocking, and I don't see any mention of turbo unlocks etc like in X99, so the only reason it seems that is made is for extreme benching where ucode may affect certain benchmarks.

ok, thanks for your answer, but I am going to change the qx9300 for a t9900, I think this one works on my laptop.

Hi @Lost_N_BIOS, this question is somewhat related to pipes80 question. So in the Apex XII 0088 bios, there are 5 cpu patch revisions from BE to C6. I am able to remove them one-by-one (in order), adjust the FIT table and it will flash just fine using EZ flash.
My question is, is it possible to choose sections of the microcode updates, e.g I just remove BE, C2, CC, C6 and just retain CA? I have not tried this because I am afraid of bricking the bios. My Apex XII secondary bios is not working at all and the main bios is all I have.

@sweepersc - Each of those apply to a certain CPU (CPUID), you can remove any one you want, or all. Once you remove the one that applies to your CPU then you are running without microcode.
If you want to leave ONLY the microcode for your CPU, yes, you can do that, but there's no reason to do such, only that one will be loaded and used anyway.
Does your system have BIOS switch? If yes, you can fix your secondary BIOS like so >> Boot to working BIOS, get in EZ Flash within the BIOS, flip the BIOS switch, program the BIOS via EZ Flash, now secondary BIOS fixed
Yes, I checked the board, it has button in bottom right corner, press this once in BIOS and once inside EZ Flash, then update the BIOS and both will then be working.

@sweepersc - I do not see BIOS 0088, is this your BIOS download page? https://www.asus.com/Motherboards/ROG-MA.../HelpDesk_BIOS/
If yes, but 0088 is some special BIOS, please link me to it. Also, please tell me what CPU you have.

Sorry, I don't know what SP135 or CB20 means? I can't comment more about microcodes until I know what CPU you have, and can look at the BIOS you are talking about, otherwise all this removal of versions you keep mentioning can't make any sense to me yet.
However, I looked at BIOS 0707, and for that, I can tell you only one single microcode would apply to your CPU, so removal of any other than the one that applies to your CPU would not matter at all (unless you break BIOS, or don't fix FIT etc)

@Lost_N_BIOS cb20 is cinebench 20 software most popular for testing the CPU performance yes and not overclocked

Hello guys,

I am trying to do a microcode downgrade due to the newer UEFIs have disabled Undervolting with Software.
I've tried to follow the guides but have been only partially succesful.

As you can see in Image the first two microcodes have been downgraded to B4, but second ones have stayed D6.

Can anybody point me in the right direction where I've made an error?

I have uploaded the files to h**ps://drive.google.com/drive/folders/18px...Uj7?usp=sharing

Thank you very much for this Guide!

Kind regards
Tobi
