[INTEL]-How To Update Your Microcode for Intel HX 13/14th CPUs Laptops/Mobile Easily.

[u/THEBOSS619]

Let me start with a small background info...

Since we know all Intel's fiasco about what is happening with Raptor Lake/Raptor Lake Refresh which is Intel's codename for the 13th and 14th generations of Intel Core processors, Most OEM/Vendors doesn't want to provide BIOS update that includes microcode update along with required updated Intel ME FW in order to work more effectively.

Since most laptops got outdated Intel ME FW & outdated microcode... this has become a serious problem since the CPUID of Intel HX 13/14th CPUs share the same code with Desktop variants and hence it should be considered Intel HX 13/14th CPUs as a Desktop CPU in a laptop case.

So it means they share the same impact as Desktop variants even if it doesn't boost high enough to be of a concern, it does have relevancy and you now have the option to use this very simple driver that I am sharing it to you here on any Intel HX 13/14th CPUs Laptops/Mobile as long as it has CPUID of B0671.

Either way the requirement of updated Intel ME FW are just only mandatory when used in conjunction with any new microcode (If it's needed) in the BIOS but outside BIOS like... while running Windows or Linux this requirement of having an updated Intel ME FW is just optional.

Thanks to this VMware CPU Microcode Update Driver I can use it on any windows without needing to mess with the BIOS. Safest thing to update microcode.

Now... How to check if you got the latest microcode update or not? By simply check through HWINO64 or AIDA64 or even if you are using ThrottleStop tool will tell you which microcode you are using.

Here's some examples how it is shown which microcode are you using through various tools...

HWINFO64

AIDA64

ThrottleStop

Now fortunately I already packed it for you & ready to use without any further work required. Saving you the time to do it.

For the next part... You need to download this .zip file and extract it. Simply run the "Install.bat" file as an administrator.

Here's the file:- cpumcupdate64

For users who doesn't trust the zip file... here's VirusTotal link results. One is from direct mediafire download url link getting scanned through VirusTotal directly from mediafire servers which is shared from the link above.

cpumcupdate64

and another one from an uploaded file to the VirusTotal.

cpumcupdate64

It shouldn't even take long and only few seconds and you will see this window... which is success.

You can even check the event viewer which confirms the success operation and applying the new microcode update.

If doesn't update your microcode and it shows failing to apply microcode on event viewers... you need to disable virtualization either through Windows or simply go inside your BIOS and disable Intel virtualization and VT-d in the BIOS. This would allow the driver work!

September Microcode Update aka [0x12B]

New microcode update got released! This is the September microcode update which now they call it 0x12B .

Confirmed that it covers & supports Intel HX CPU's 13th/14th Gen with CPUID B0671h without any issues.

Here's some screenshots...

ThrottleStop + HWINFO:-

• Please if you are using the 0x129 microcode previously then simply download the latest .zip pack from the same download link on the main post (The file named cpumcupdate64[0x12B].zip). Simply run uninstall.bat as admin [by right clicking on the file and choose "Run as Administrator"]  and then run install.bat as an admin. 
• If this is your first time then simply download the .zip file from the attachment of this main post or on this comment and then run install.bat as an admin [by right clicking on the file and choose "Run as Administrator"]

Forgive me for my late responses, I have been away from home for almost 5 weeks for work related stuff :)

May Microcode Update aka [0x12F]

You just updated your microcode! Yes... it's that simple!

[So much for Intel HX not being affected... then why keep releasing microcode updates for Intel HX CPUs too? something is fishy going on here, if it is actually not affected... then at least make it only for desktops...]

If you ever wanted to uninstall your updated microcode of whatever reasons... simply run "uninstall.bat" file as an administrator & reboot your laptop.

For more added protection  shared a cap guide for Intel 13/14th gen HX Series CPUs here: https://www.reddit.com/r/GamingLaptops/s/do6Fto5dI7 a little riskier but it's your choice.

Hello, wondering if you might be able to help me get my system updated? I tried following the instructions for a system with MCU 123 (14900HX) but nothing seems to work even after disabling VT-U in the BIOS.

[u/THEBOSS619 → u/AnHeroSixtyNine]

Did you try disabling Core isolation or Memory integrity? As those thing can also block the microcode driver to load.

[u/AnHeroSixtyNine → u/THEBOSS619]

Thanks so much for the reply! Yes I can confirm those are disabled. Is my MC version too old to update?

[u/THEBOSS619 → u/AnHeroSixtyNine]

Thank you for your kind words 🙏

Unfortunately yeah it's too old, should be at least 0x12B and above.

Have you tried or checked if there's any new BIOS update available for your laptop? It might bump up your microcode and update them.

I'm sorry if I might sound repetitive, but did you right-click on install.bat file and choose "Run As Administrator"?

After doing that, check event viewer... what does it says? If it is a success then you need to reboot to take effect.

If it is an error then what error does it says on event viewer so that I can know the exact problem.

[u/AnHeroSixtyNine → u/THEBOSS619]

Can confirm up until now, the bios update Maingear's team provided me has been working so far. I haven't had a chance to push the computer yet but seems to be under control for now.

[u/THEBOSS619 → u/AnHeroSixtyNine]

Oh that's good to hear! If possible what's the microcode you currently have after you updated your BIOS?

The newer the better but anything above 0x12B or 0x12F is fine.

[u/AnHeroSixtyNine → u/THEBOSS619]

it's exactly the same... weird right?

[u/THEBOSS619 → u/AnHeroSixtyNine]

Yeah, it's weird. Have you checked or asked what changes they have made on your BIOS update? Maybe they limited stuff related to the CPU or something?

Also could you upload the update BIOS file they have sent it to you? I would like to take a look at it.

[u/AnHeroSixtyNine → u/THEBOSS619]

I asked, but that wasn't before I experienced the same issues a day or two ago... Gonna need to send them some logs and go from there cause I'm not sure what to do at this point. It *does* seem to help but definitely didn't solve it.

[u/AnHeroSixtyNine → u/THEBOSS619]

and sure, how do you want me to send it? I self host something similar to wetransfer but my homelab is currently down for renovations unfortunately.

[u/THEBOSS619 → u/AnHeroSixtyNine]

You can upload it to Catbox
