Hi! Much respect to @Dufus, @C-Power/Tw0tch.
I have MSI X99A Raider and xeon 2650 v3 and I would like to try this mod. Sadly UBU doesn`t support msi bios. So could someone give me a proper instruction how to earse ucode manually or make such modification for me and share bios https://msi.com/Motherboard/support/X99A-RAIDER.html#down-bios
I would appreciate any help)

You may try this one I`ve moded by the same principle.

Not 100% sure so on your own risk and be ready to restore.

And I suppose you have QS or prod. unit processor with microcode 306F2 otherwise it doesn`t work for you

@Dufus

Here are the hex values you ordered a while back. I tried putting them through a hexadecimal to text converter, but it was all gibberish :p
0x1ad: 1c1d1e1f20212323
0x1ae: 1717171718191A1B
0x1af: 0000000000001717
0xCE: 20080C33FB811400
0x194: 0000000000000000

use UBU for asus, and "biosflashback" for flashing

I am following the process and Ubu says "this Bios on Aptio 5 platform, known issues: - There may be problems with updating the cpu microcode"


so, C-Power/Tw0tch said that its better to use MMtool in this comment on page 3:

Great little compilation of steps to go through for the ones not wanting to read/go through everything posted up till now ^^

Edit:
Beware that using UBU only can cause your bios to not boot if your on one of those APTIO 5 biosses (UBU warns for that)

I had this a couple of times and had to use MMtool to remove the mirocodes, then just open the bios with UBU and just immediately press 0/Exit and save that way.
Worked every single time for me on both Extreme4 and Extreme6 Biosses :)

What should I do? I managed to mod the bios in UBU but I am afraid of the motherboard not booting :/

Things aren't looking too good on my end. I've tried flashing the edited BIOS (using the UBU toolkit) on my SM DP board, but the system had trouble booting up. I ended up spending a few hours restoring the system to its original state.

Well, for the first glance Dufus hex method should work on Supermicro dp mb as well. If you have the way to restore system and ready to try again I could try to mod a bios for you.

Please tell me someone is finding a way to make this work with Dual E5-2686v3 on ASRock Rack EP2C612D16C. A higher all core turbo or similar would be so amazing. So would having a bunch of cores @3.5!

As it's an Asrock board, the UBU toolkit might work.
But as said before, the 2686V3 only goes to 2.8GHz with the mod (and 2.9 if you OC the BCLK to 105).

Hey, I already managed to flash the modified Bios, but I am stuck at getting in the UEFI Shell and loading the V3 driver. I am having troubles with Secure Boot and properly booting from the Usb, any help? thanks!

You can switch to BIOS B from the switch located on motherboard, and try to recover bios A , feature you need to do this is called "Secure Backup UEFI".
Did you followed someEEguy post?
https://forums.anandtech.com/threads/what-controls-turbo-core-in-xeons.2496647/page-3#post-38703348

Also , did you removed broadwell microcode? You are just supposed to remove haswell micrcode and leave broadwell intact.

Edit:
Try to use this bios , its for taichi ver 1.40, I use it and it works (also have taichi)
https://drive.google.com/file/d/0B_ZQtaxTWt-QdGNGSnA5U0UtMkU/view?usp=sharing
Put it on a FAT32 usb drive and update from bios.

Hi! Is this the bios that is already modified for maximum turbo in all cores in Xeon v3? I have 1x2673v3, 1x2686v3, 1x2669v3, 4x2658v3 and 1x2683v3 and my motherboard is the X99 Taichi bios 1.40 with a 2673v3. Can I install it without problems? Thank you!

If you run tests on all of those, please also test Corona Render Benchmark :)

E5-2683V3 running 30x all cores.

It is a retail CPU, perhaps the ES and QS samples that a lot of people seem to be using are a bit flunky, idk.

http://valid.x86.fr/9shu3g There's a CPU bench score there too.

Hi! With modded bios, will I already have the core ratio feature available or do I need to do other things? If yes, please send me the modded bios. I use x99 Taichi and I have 5 CPUs v3 to test: 2673v3, 2686v3, 2669v3, 2658v3 and 2683v3. Thank you!

No - lol.

Which is why I'm backing up my drives at the moment and doing a clean install. Because it's worth it ^_^

Edit:
Yeap, all working now! This just makes me want to get a 2686 now and have 18 cores/36 thread at 3,5ghz+ :p

Click to expand...
I'm trying with the 2673v3 QS and I'm not getting it. I already installed this bios:
Https://drive.google.com/file/d/0B_ZQtaxTWt-QdGNGSnA5U0UtMkU/view

WP_20170213_16_51_09_Pro.jpg

And I removed the mcupdate_GenuineIntel.dll file from the system32 folder:
Capture.jpg

But I'm still not getting maximum turbo on all core.
Is something missing or does not work with this CPU model Xeon 2673v3 QS 12 core?
I have others CPUs: 2683v3 Retail, 2686v3 QS, 2669v3 QS, and 2658v3 QS
Please, for one answer.
Thanks!
Edit:
I forgot to post the image where my biosmod did not appear the "CPU Ratio".
WP_20170213_17_39_00_Pro.jpg

Thanks!

I received my motherboard, ram and cpu's. I ended up going with a pair of E5-2667 V3 ES cpu's. I have installed Windows 10 and last night I finally was able to install Ubuntu 16.04 with the motherboard in UEFI bios only.........that was a major pain in the rear.

Now I'm just learning what to do by reading all the post and links.

@vadimkara, did you manage to make it work?

I have an E5-2650v3 engineering sample, CPUID 306F1, currently running microcode 0x80000013 as reported by /proc/cpuinfo.
I tried to run ucode-less UEFI and V3.EFI but got stuck on 79 as happened to @vadimkara.
Motherboard is ASRock X99-M Killer.

Any tips to this?
