Hey guys I have a Hackintosh( with no Windows partition on it ) with and ASUS X99 AII running a 2996 v3 .
My question is : is it possible to run OSX on an unlocked bios and also is there a guide for beginers?
Maybe someone could be kind enough to patch me a bios on their machine for my motherboard
Well i run it but i am not getting good values. Never got 3,8Ghz even on single core, on multi core i got a very short peak of 3,1Ghz (which is in fact better than standard) i tried all efi's from v3x4 rc8 but no luck. I saw test result on Geekbench that were a lot better on hackintosh with same cpu (E5-2696 v3 oem).
You need to install a patch bios (which is mostly possible via usb) and patching is possible with osx or ask someone to patch it, or search in this topic there are a lot of bioses shared.
Next EFI loading is very easy because you use osx, i think you use clover? So 2 options or start shell in the boot menu of Clover or put one of the EFI files in your EFI/Clover/drivers64UEFI folder

But keep in mind that you maybe have to suffer some freezes and change bios settings to get it working.

is it possible someone can compile a EFI with power enabled and mc 27? or how can i do this? I have a Asus ROG X99 Strix board and use a E5-2696v3 and try to get better value's?
On single core my cpu does not get higher than 3,6Ghz (on windows on OSX it is 3,4Ghz) also multi core is not as high as some people here 3,1Ghz (Windows 10) and 3,3Ghz (in OSX 10.13)

Problem on a hackintosh is that it freezes when i use a EFI without microcode... it works sable with old v3x2_cp27.efi but not with newer like v3x4-0.10b-rc8_p1.9v.efi for instance... and with v3x4-0.10b-rc8.efi it os X does not boot at all, same count for Windows 10.

Is there be somebody that can and want to compile a v3x4 efi form rc9 with mc27 or mc39? please?

It's already patched for your X99 A-II.

Remember to update bios with bios flashback feature button, not the standard update in bios

Can you share the EFI files I need for clover please?

There are a lot of efi's over here you just need one.... but first install a modded bios.
here are some...

i have problems with them just search in this topic for the v3x2-cp27.efi that one worked for me on osx. I am searching for one that work stable of the v3x4 versions of RC8 because i don't know how to patch EFI. I would love one of the v3x4 RC9 versions with mc27. I think that will work but i don't know how to compile them.

OK, maybe I missed this in the 73 pages, but can an E5-2695v3 ES chip be overclocked on an X99 Taichi using multiplier ? I guess the main question is, can ES chips be overclocked in general using multiplier. I know the retail ones are locked.

i found out that i have in windows same result with or without an EFI driver....
Also i downloaded a modded bios but this new one has MSR lock... so it won't load any of the v3x4 efi's

all chips are locked. You can only unlock turboboost clocks to all cores on ES stepping 2 and retail ones

After installing a latest (here found) patched bios i get this error

[FAILURE] Overclock enable lock bit (MSR 0x194 [20]) set

So it won’t load?!? Anybody knows were to find this in the latest Asus ROG x99 Strix bios?

or find the version i had before

Thanks i downloaded for my board too.... problem the MRS 0x194 is set so it won't load any of the v3x4 efi's and doubt if the older v3x2 version load.... with or without EFI i get the same result.... (3,4Ghz turbo 1 core, multicore 3,1Ghz) on a E5-2696v3 hope somebody can help me out i tried to do it my self but that was more then 6 months ago and i know i failed

RC8 binaries are now up and available for download:
https://github.com/freecableguy/v3x4/releases/tag/v3x4-0.10b-i306f2-rc8

Major changes:
1) Fixed a bug that was preventing PowerCut from being enabled if set. Remember to set VCCIN to Auto in BIOS (if available) when using drivers with PowerCut enabled. Also, if the driver notifies that a reboot is required then simply do a restart as soon as you get to your OS login screen. PowerCut requires a fixed VCCIN and VCCIN can only be set on reset. Hence, PowerCut will require an immediate reboot after any shutdown (not required between successive warm resets).

2) Added back ability to adjust SA voltages. There may be some power savings here but hard to tell if not included in PCU determination to increase boost (probably not). Those with 2S systems will probably care more as this includes the QPI link power budget of which a large part would be the 4.8GHz link from CPU0<->CPU1.

3) Behavior change: set Uncore to max speed and force max speed. This may be a personal choice for some as this does increase idle power and as well may remove power from the power budget that could otherwise be used for the Cores.

4) OC Lock Bit in MSR 0x194 is no longer set. You should now be free to continuing playing with settings post-boot.
Thanks for all your work so far!

Would it be possible to implement microcode 27? This because i also run osx and without it freezes
Or can somebody tell me how to implement a mc in the EFI file....

ever since I flashed this bios the asrock instant flash doesn't work anymore and I am unable to flash another bios. The whole system freezes when instant flash is executed.

has anyone tried the bios linked here and found them working without problems?

Is there another way to flash the bios? to flash it via dos it looks like I need another modded bios as well...
To flash via dos, you just need a bootable DOS disk, then the flash utility for dos, and the bin file for the flash

Is the "flash utility" for dos a one size fits all or do I need a special Asrock Rack one? Because I cannot find an asrock rack flash utility for dos. I can download a .exe from their website but that includes both the bios as well as the flash utility, so I cannot flash my own preferred bios.

Download it, and I think the flash utility is exactly what you need, and the bios. Now to just get a bootable floppy or USB stick to boot dos.

If I take a look at this page, it sounds like the bios is included in the exe.

http://www.asrockrack.com/support/faq.asp#DOS



The thing is, if I try this and it starts to flash the bios to the integrated bios of the exe, I'm back to the very old unpatched 1.30 bios version. If the instant flash tool doesn't work on that either I have no way to get back to a modded bios.
That is why I'm hesitant to just try it out.

Where can I source code to this efi driver so i can modify and compile?

https://github.com/freecableguy/v3x4

EDIT: I will add rc9 compiles over the weekend as I am 99.9% sure this the final RC. Now taking requests for target builds INCLUDING compiles for Broadwell, if requested.

I will also post a tuning guide. Executive summary: Power Budget = Core power + Uncore power. Formula for computing is largely known, specific tuning parameters (likely part of microcode data segment delivered only via encrypted payload) are not. Regardless, reduction of both through both programmatical differences (i.e. increasingly negative Adaptive voltage offsets) and "behavioral" changes (i.e. leave enabled dynamic Uncore P-state tuning) are equally critical in achieving maximum performance in conjunction with use of this latest driver.
