Good evening all.

I am trying to force Max (3.7GHz) Turbo Boost speed with All cores loaded on my Haswell E3-1265L v3 CPU. It seems that I may need a microcode update as currently, settings in BIOS make no change.

Could someone recommend to me which microcode version has this feature still enabled?

EDIT by Fernando: Thread title shortened

So after further reading I believe that one of the following microcodes will be suitable - however I'm having trouble finding them:

cpu000306c3_plat00000032_ver00000001_date20121030.bin

cpu000306c3_plat00000032_ver00000002_date20121130.bin

cpu000306c3_plat00000032_ver00000004_date20121208.bin

cpu000306c3_plat00000032_ver00000006_date20130116.bin


I got these versions and dates from MCExtractor by searching by CPUID 306c3.


Does anyone know of a source where I could download these old microcode versions?

I've gone through all of the microcode.dat files at https://downloadcenter.intel.com/downloa...ocode-Data-File

The lowest version I was able to find was cpu000306c3_plat00000032_ver00000012_date20130702.bin which was contained in the 20130808 bundle.

I was able to insert version 12 into an early BIOS version and flash it - but it didn't solve my problem. I remember reading somewhere (can't remember where) that prior to version 7 this would work.

I think you could downlaod UBU V1.69.17.4,it contains these files what you want.

Really? I've only ben able to get the latest microcodes working from UBU? How do get these older microcodes? I can't even find these on the github repository of microcodes.

From UBU 1.64_1

Wow, thank you so much! Where were you able to get these from?

Yes,I'm sure. I mean old version UBU such as V1.64 already contains these files.And you could find them under this path:UBU folder->files->intel->mcode->1150.
I guess you could run UBU updating bios file directly,after replace these files.
By the way, lfb6 provided files should come from that folder.

Those microcodes were part of an old UBU version, as I wrote before.

Where can I download one of these older versions of UBU? All I can find are links to the latest.

I think you could use latest UBU.Deleting newest mcode files,then copying old files that Ifb6 supplied on #7 to same folder.

The thread " [Tool Guide+News] "UEFI BIOS Updater" (UBU) " mega download link include UBU V1.69.17.5 and you could try it.
