Yeap!!! Cpu microcodes is only security updates! i dont know exacly if destroy Overclocking if you use oldest cpu microcode maybe i need to test it

22

@panosxidis - Yes, only testing each one on your own system, benchmarking in your own way, will tell you which microcode is best for your system.
Be sure you check what the actual live microcode being used is once in windows, you may need to stop windows from replacing BIOS one with it’s own.

23

yes you rename or delete on system32 mcupdate.dll the intel one yeap

Hi There!
I’m looking for cpu506E3_plat36_ver00000004 microcode.

26

@Erebor As you likely know cpu506E3_plat36_ver00000010_2015-04-22_PRD_C85B1006.bin is the earliest I have for Skylake but if you do happen to find any earlier than this then please let me know.

You may find earlier microcodes in very early BIOS from Vendors I that I did not check such as Supermicro and Colorful, I have checked a lot of Asus, MSI, Gigabyte and ASRock Z170 BIOS.

27

@chinobino MC Extractor v1.40.0 (ubu tool) shows version 04 from 2015 02 23 but I can’t find a way to download it. There is one tiny difference between 04 and the rest starting by 010, designated platform for 04 is 032 and for 010 and newer is 036.

28

@Erebor What file are you opening with MC Extractor to see that microcode?

The Platform ID is sometimes changed during CPU production, Skylake-X also changes from 97 to B7 and Kaby Lake from 22 to 2A, it doesn’t seem to matter.

29

You can open UBU tool (UBU.bat) on any computer and it will detect installed bios. Next you press 5 for Cpu microcodes and S key to search for microcode aviable in database according to the cpuid you are interested, in my case is 000506e3. The microcode I’m looking for exists.

30

@Erebor Can you zip the BIOS file and attach it here?

31

@chinobino
First download UBU
https://onedrive.live.com/?authkey=%21AB…014229B9E752333
Second run UBU.bat, it will detect your bios. Next press space, then press 5 for Cpu microcodes and S key to search for microcode. You can input any cpuid like 000506e3.
My bios has cpu506E3_plat36_ver00000010_2015-04-22_PRD_C85B1006.bin
I’m looking for cpu506E3_plat32_ver00000004_2015-02-23_PRD

32

@Erebor UBU is listing all the microcodes in the MCE database file (MCE.db). Plutomaniac must have had access to that microcode at some point to add it to MCE.db - you could try asking him if he has the source file.

33

Will do, thanks. But if you happen to find this microcode send me a pm.

34

@Erebor Np, just remember that any microcode before BA does not include the Skylake Hyperthreading bug fix.

35

@chinobino To be honest hyperthreading is mildly useful, I am looking for a way to overclock my 6700hq. My descriptor is unlocked, management engine is disabled (isolated) but I can’t get my laptop G9 591 to post with microcode removed. Maybe ver. 04 could do the trick (if it had the “bin bug” I’m looking for)

@Comobo Thanks for bringing that to my attention, file size = 0 bytes.

I don’t have the source for that microcode so it has been removed.
