That is fair enough, I was hoping that microcode 3C would not slow down the system has much as 3B.

Please update the MOD to the latest version of the previous BIOS version of 3301 for Asus Rampage V Extreme, because among all versions of the BIOS only on this version, I have DDR4 memory running at maximum performance, and on RealBench V2 Lederboard this version of the BIOS 3301 is very popular as one of the effective ones for overclocking! https://rog.asus.com/rog-pro/realbench-vâŚPU=intel&view=1

Here https://drive.google.com/file/d/1erkYkHwâŚiew?usp=sharing version of MOD Bios 3301 from July 25, 2016.
Since the release of July 25, 2016 BIOS version 3301, the microcodes of the Haswell-E processors have been updated. I have an Intel Core i7-5960X.
Is it necessary to embed microcode updates in BIOS 3301, or are they optional?
I have not updated cpu microcodes as the latest ones are buggy and make PC slower than before.

Just now I noticed, checking the checksums, that the file by link https://drive.google.com/file/d/1erkYkHwâŚiew?usp=sharing is not a modified BIOS, but the original one is unchanged from Asus. OK. 3301 is no longer necessary.
I stopped my choice on the BIOS 3402 for RVE.
You can upload the updated MOD BIOS 3402?
with:
- Latest orom/efi LAN
- Latest orom/efi SATA
- Latest CPU Microcodes (3A/21) for Haswell-E/Broadwell-E
I apologize for the annoyance.
Thanks!!

Download new 3402 MOD for RVE & Updated my BIOS. The computer does not boot! Tried several times unsuccessfully.
The MOD is not working. Rollback to the old MOD 3402 released 10/20/2016 with the microcode 38 of the CPU Haswell-E.
Sylar76 please fix the MOD 3402 with the updated microcode 3A, latest orom/efi LAN & latest orom/efi SATA.
The Spectre vulnerability is caused by side effects of speculative execution, and speculative execution is how the execution pipelines get a lot of their speed. Since they canât fix the hardware defect that is causing those side effects, I expect they have to avoid the speculative execution. I doubt youâre going to see a version of that which doesnât negatively impact performance.

Updated to the latest fixed version. Same. I turn on the computer and after 10 seconds it turns off.
Probably, the hardware conflict of microcode 3A with Bios 3402.
Thanks for the help.
Iâm going to try 3402 mod on my machine (Iâve a 5930k CPU).
@Darkseed
Ok, this new one works like a charm.

The last fixed MOD 3402 worked!
Thanks!
Hey, @Sylar76 can you please build an updated uCode ffs with latest microcodes (2A BDW-E, 3C HSW-E, 14 BDW-E ES, 14 HSW-E ES) if itâs not too time-consuming? Looks like I am doing something wrong with GenFFS =)
I know that 3C has some problems with performance, just want to play a little on linux with it.
P.S. Iâll upload cpu306F1_platEF_ver00000014_2014-01-10_PRD_9F835FBB.bin if itâs needed. Thanks!
@Unb0rn
Here we go.
Iâve generated both .FFS and .raw files.
Let me know if it works.
Microcodes_haswell_broadwell.zip (250 KB)
Wow! Thanks a lot! Any links? =)
Also, is it something more than:
GenFFS -s -t EFI_FV_FILETYPE_RAW -g 17088572-377F-44EF-8F4E-B09FFF46A070 -i cpu306F2.bin -i cpu306F1.bin -i cpu406F1.bin -i cpu406F0.bin -i MPDT_BOOT_YES.bin -o RampageVuCode.ffs
Just to know where is my faultâŚ
I never used GenFFS. My method is based on the âold schoolâ. 
P.S. Link attached.
Works like a charm! I even had to remember some manual FIT-fixing =) Thank you once again.
What about the poor performance with 3C microcodes ?
I canât understand why from 3B-3C microcodes performance on Haswell-E (Iâm using a 5930k) suddenly dropped.
