@lost_n_bios
i update all microcode flashed it & recieve cpu today xeon e5410
cheers its lga 771 working fine on my lga 775 socket.
thanks a lot for guide.

@earthoo7 - Great to hear all is working smoothly!

MSI has updated their BIOS for some Z370 boards, it contains the CAh microcode for the 8700K/906EA CPUs, and it's quite the disaster. I'm writing this to caution against upgrading to this microcode if you care about voltage controls, power consumption, (some) benchmark scores etc. Undervolting is all over the place now, to get the same power consumption I'd have to use a -0.115V offset instead of -0.085V in the previous BIOS, the uncore multi was lowered with one bin from 44x to 43x, and Cinebench dropped 50 points.
I assume this is because of the Plundervolt vulnerability and Intel trying to fix it. An average user shouldn't notice it I guess, but for those on laptops that undervolt it will be quite the mess.

@davidm71 - can you please update UEFITool versions to 51 and or 51+ - As you know, both show ucodes differently, so your wording of guide may need update depending on which you choose or if you give info/tips on both
And regular version 25 please, 22.3 causes some issues, as does 26-27 in some BIOS too, so I suggest advising 25 for insertions now (but it's your guide )

I mainly am asking now because someone following this guide linked me to it, and after checking their BIOS I see critical module removed in a volume they didn't even edit, so I came to see how/why, and then I tested, it's due to old 22.3 version.

Thanks!

@Lost_N_BIOS What guide are you referring to? I am not the author of Uefitool as I am sure you know that is Coderush. All I did was fork his code adding visual enhancements. Been a few years as well and as such my c++ is a little rusty. Furthermore not sure where I put that modded code. Would love to upgrade it to latest version. Thanks.

@davidm71 - I am referring to this guide, page/post #1 I just meant update your links and references from old versions to the newer versions I mentioned instead, so users run into less issues (since versions mentioned in the guide originally are now old/dated etc)
Not sure what modded code you mean? Maybe I didn't explain well what I meant? I just mean for example, you link UEFITool 22.3, I suggest changing that to link to and suggest version 25.0, and same for A40, change to A51 or above (51 shows ucodes differently than 53+, so you may need to adjust your guide comments based on that)

Thanks! Hope you get what I mean now

@Lost_N_BIOS Hi again, been a while. I came back (since I have a little spare time) to try and look for improvements for my PC. And I looked for new Microcodes, and there is no any new.
But, I see now that my BIOS does have a possible ME update. My BIOS version is 9.1.37.1002 and there is version 9.1.45.3000 (I know I can't update mine to v10 and above. But I'm not so sure if I can't also update to v9.5).

Edit: I realized now I need only 1.5MB file so there is still a newer version of ME, version 9.1.40.1000. Correct me if I'm wrong, I'm not so sure I fully understand here everything.

So my question is, do I really have a possible update or I just didn't understand here something right.
Thank you :)

U can only change ME SKU 9.1 to 9.5 if the the manufacturer released a bios update based on ME 9.5, other than that the current 9.1.40.1000 SKU 1.5Mb is the last available to you.
Presuming that u know ur SKU is 1.5...

@MeatWar Thanks you for answering and helping me.

So right now the in the latest BIOS for the manufacturer is ME is 9.1.37.1002_1.5MB_PRD_RGN.bin, so I can only update to 9.1.40.1000_1.5MB_PRD_EXTR.bin as you said. (Sorry for annoying. I'm just very afraid to screw my board).
Does the RGN and the EXTR matter?
Here it says to pick only the most similar ME RGN firmware.
-------------------------

One more thing. I saw a BIOS mod for X99 chips which allows you to push all Xeon (only V3, maybe V4 too but not sure about that) cores to the maximum.
Now I followed this, and I just want to make sure that before I flash it on my board it isn't going to kill it. I have GA-X99-UD4-CF.
Thanks for all helpers!!

For ME update please read THIS post and follow guidelines and tools provided. Remember whenever u flash bios ME version will revert to the one in bios file.
The bios mod is another subject to further investigate and later request help on ur intentions, on this subject i think @Lost_N_BIOS is more qualified to answer this matter.
But i see cpu support listing E5 V4 Broadwell-EP 14nm series on Gigabyte website

The Dual-Bios and Q-Flash Plus USB port on ur board is ur angel guard to test mods.

@Blizz - RGN/EXTR only matters if you are using the cleanup guide and flashing via FPT. If you are flashing with ME FW update tool (FWUpdLcl.exe), as you should, then it does not matter (ie use latest EXTR)

I cannot help with V3/V4 Xeon unless you link me to some forum thread with the exact modifications you need done, then I can do it for you if needed.
This is not something I keep up on or do often, so I can only help when direct how-to info is chosen and provided by the user, then I can do.
I cannot use any video guided method, but I can "Check" your BIOS vs stock, to see if "in general" your mod BIOS is "OK" to flash and not damaged in any obvious way.
If you need me to check like that, give me model name so I can grab stock BIOS and then upload your mod BIOS for me to check

@Lost_N_BIOS and @MeatWar Thanks for all your help!!
So, do you happen to know what version of ME and what MC should I use to achieve the best performance?
-------------------------

This is the website that I used to do the mod, and here is my mod. Thanks again :)

@Blizz - It should be stated in your guide about what ME FW, I'm not sure, I can't watch a video for this kind of thing.
I believe the method you are using you remove the microcode anyway, so then whatever windows loads once it starts will be the one you will use in OS

I got confused, i have a sabertooth z87, but asus doesn't update bios for support 5th gen core cpus, i not sure i understand about this, it's that i replace my original micro code with "cpu40671_plat22_ver00000017_2017-01-27_PRD_AD769E20.bin", i will not able to use 4th gen core cpus again and i only can use 5th gen core cpus? or after i replace it and it support both 4th gen and 5th gen core cpus?
