More Skylake non-K Unlocked MSI Z170 BIOSes Available: 16 Motherboard Models Supported

In a thread posted in our Skylake overclocking sub-forum, t!n0 from The Netherlands has listed the unlocked BIOSes for 16 MSI Z170 motherboards. The BIOSes support BCLK overclocking for any locked Skylake processor, but have the same issues as we mentioned in another newsflash article. In short: no integrated graphics, no power management features and poor AVX performance.

The MSI motherboard beta support list now includes: Z170A XPowerGaming Titanium Edition, Z170A Gaming M9 ACK, Z170A Gaming M7, Z170A Gaming M5, Z170A-G45 Gaming , Z170A Gaming M3, Z170A Gaming Pro, Z170A Krait Gaming, Z170I Gaming Pro AC, Z170A Tomahawk, Z170A Tomahawk AC, Z170M Mortar, Z170A SLI Plus, Z170A-G43 Plus, Z170A PC Mate and Z170-A Pro.

You can find the BIOSes for download in t!n0's forum thread. Don't forget to say thanks to T!n0 for sharing and enjoy overclocking!

Like many of you probably would have guessed and find unneeded to mention, a little disclaimer on this matter:
*Overclocking Intel non-K CPUs is not officially supported by Intel and the BIOS versions created by MSI unlocking this option are all beta versions. Intel may choose to disable this option at any time. At no point MSI can be taken responsible for disabling overclocking for non-K CPUs.

Happy benching! :D

*Log:
- Updated on 15/01/2016 fixed BIOS versions for KRAIT and TOMAHAWK models, added new Z170A GAMING PRO CARBON, Z170A KRAIT GAMING R6 SIEGE and Z170A KRAIT GAMING 3X models
- Updated on 21/12/2015 to include working versions of Z170A GAMING M7, Z170A GAMING PRO & Z170-A PRO

Try, clear up the cmos.

Poland barti27 says:

thanks bios

Brazil Stormtrooper says:

From yesterday to today, I learned some things about MSI Z170-A PRO First, clear cmos up! . After updating the unlocked bios, I changed BCLK, saved and nothing happened Once you clear up CMOS, the multiplier went to work. Some combinations of settings can break the overclocking and BIOS reset. If this happens, clear up CMOS. Second, Set the Extreme Memory Profile (XMP) Reboot and instability. I put off. Third, Change the CPU Ratio to 37, Change the Ring ratio to 37 These two related options, cause a strange effect, in which you view the change in bclk, but it set the clock in 3.7 keep in auto, real change clock. Four Set the CPU Core Voltage to 1325 this voltage suits well to overclocking Skylake the problem and that some mortherboards station not showing the voltage correctly. IN my case I put 1,325 self in CPUZ and bios showed 1,432. So I put vcore m 1,240 Override + Fixed 0005, now appeared properly 1336. if some friends have a problem with high vcore, try switching to low I've been testing several numbers for bclk, memory and vcore. But my Prime95 blend test with 4.5GHz and ram 3091 freeze the PC, I have good memories corsair LPX 3200, does not seem to be the issue. I'm currently using the configuration of der8auer and DigitalFoundry, Core i3 4.4GHz BCLK 6100 / 2560mhz, this more balanced.

Hello guys, I have MSI Z170A Krait so, I formated my flash drive to FAT32(I puted it direcly into MB I/O), downloaded, unzipped copyed the BIOS to my flashdrive. Restarted PC booted to bios. Restarted again to get into Flashmode. It recognized my flashdrive but the bios won’t showup. Is there posibility that this bios is for Z170 Krait (non-A version).

Now later i looked up to file names, there is difference between OCbios: E7984IMS.B5T non-OCbios: E7984IMS.A50(from MSI website). When i renamed the OC bios to the "*.A50" it showed up, but still, it is BIOS for non-A Krait MOBO, which does not have USB 3.1. So my question is: Is it safe to use it on my MSI Z170A Krait?

Thanks

Hi all, I'm new in forum :D.

I have been reading previous messages to try overclock I5-6400 on MSI-Z170A-KRAIT-GAMING, I installed the lastest version E7984IMS.A6T and try to modify stock values.

I've been able to change Extreme Memory Profile (XMP) to Enabled and CPU Base Clock (BCLK) and fail reboot because I have not been able to change Ring Ratio and CPU Ratio over 33 stock.

Has anyone been able to overclock non-k CPU with this motherboard?

Thanks to all.

That is normal, you can't increase or decrease CPU ratio with all Non-K OC BIOS.
The proper way to overclock on these BIOS is to adjust manually BaseClock along with vCore and memory frequency.

Make sure you clear the cmos before you attempt overclocking. I also noticed that whenever my overclock failed I had to clear cmos before making any changes.

Clear CMOS is jumper or onboard button, F6 is to load default settings. To overclock with Non-K BIOS you need to adjust manually BCLK + memory frequency + vCore all at once.

I don't know what is your issue, I tested B5T and A6T on Z170 KRAIT GAMING, both worked without any issue, so it must be something you doing... All you have to do is to flash B5T Set up max CPU ratio Set up BCLK Set up RAM frequency Set up CPU vCore accordingly That's all...

France pepinorang says:

I had the new Z170A GAMING PRO CARBON laying around for some marketing stuff and I figured I'll give it a small shot as well.

Maxed the CPU to 4.6GHz and memory at DDR4-3554:






FYI, with Loadline Calibration enabled and 1.4v set in BIOS, vCore in idle was 1.377v.
vCore under Prime95/OCCT load was 1.381v (+0.004v) all measured with Digital Voltmeter on PWM resistor.
It is also on par with the KRAIT GAMING motherboards and the Z170A-G43 Plus I've posted in previous post.

Absence of power management is indeed one of the technical limitations that all Non-K BIOSes share, regardless of vendor.
It will (most likely) never be fixed, sorry.

"Unlimited restart" (00-19-FF-Reboot in loop) happen on motherboards without external clockgen (Only Z170A GAMING M5/M7/M9/XPOWER include external clockgen) whenever OC fails/crash.
You have to clear CMOS and turn OFF your PSU until motherboard is discharged to get it back to normal.

Sometimes this issue is still present afterwards when you try to overclock BCLK, which in my case was the Intel ME firmware corrupted and re-flash BIOS via M-Flash fixed it.

United States qihei says:

BBS in China, I asked several have Z170 KRAIT, they all said that his B5T upgrade, but no one can overclocking BCLK, I think is the problem that the BIOS, you can test overclocking BCLK, is it because your CPU is ES version, like some ES version is unlock BCLK

Yours is different, as you said you can NEVER boot and it's not the same board neither.

About 5 minutes.

pepinorang said: I tested this one, again without issue... See screenshots I posted.
What's the post codes ?

Anyway, I'm going to re-test all 17 supported boards with retail i3 6320, but I'm convinced I'm just wasting my time...


There is no post codes as it does not even get to that point, it reboots before that. But like I said its not a problem, as it does it in rapid succession for 5-10 times and then boots up fine, maybe an extra 30 seconds for booting.

Try turning off XMP, it helped me... I think. It reboots about 3 times before posting now. I've got my 6600 running at a conservative 4 GHz at the moment.

FIY, Non-K OC will still work in the future on MSI motherboards and there won't be special BIOS needed anymore.
When BIOS will detect Non-K CPU it use old microcode and display an option to enable Non-K OC. :)

Will let you know which BIOS versions exactly asap.

So far, I don't find MSI Non-K BIOS with XP ACPI Support man. You might want to select MPS Multiprocessor mode during the install :)

so will msi release official bios or should i install this? what makes me concern is my system is like 3 months old. i dont want to break things atm ^^

You can already use latest official MP BIOS.
When used with Non-K CPU it will display an hidden option that when enabled will allow Non-K CPU OC.

Hi all! Pls help me i have problem 2 months ago I successfully overclock my i5 6500 to 4.4 (1.35v) .A today I wanted to optimize the voltage (had blue screens) and lowered voltage. After that my PC is not turned on and the BIOS default settings restored. After this I would like to introduce the best value BCLK (135.00) and voltage (1.25v) And when switching windows 10 that I saw standing on the default BCLK (100.00) Thereafter, I downloaded the new BIOS.

Your ME is probably broken, try to flash BIOS with M-FLASH and/or FPT several times until it works.

Usually Clear CMOS after failed OC is needed in order to reset Intel ME.
Either it is your OC that is failing due to too low vCore, or you could also have the same issue than Joe90br and your Intel ME might be broken.
Only advice I can give is to try to increase voltage back to 1.35v or to flash your BIOS several times until it works...

Anyway guys, please do note that Non-K OC is not officialy supported and will never be.
I have personally tried the BIOS listed in this thread and they work without major issues, so I'm not going to spend anymore time on this, you have to figure out yourself.

Problem solved! In the new update is a new tab where you can select the NOC mode and overclock the processor

Thanks for help!

So I'm getting the vibe from pepinorang's last post that he's about done with this thread for goodsies, so I guess this is more of a general question for anyone who knows the answer, but does that mean that the MSI official BIOS 1.B (in my case, for the M7 z170, and published on 2016-02-23) actually allows non-k overclocking? I'm not brave enough to check myself, as the changelog simply says

- Updated CPU microcode(0x7C).

and updating microcode (to my ignorant self) feels like it would be A Very Bad Thing if I want to keep OCing my i7-6700

On 03-02-2016 (after 1.B was published), pepinorang mentioned that future bioses will have the "switch to old microcode secretly" option, but that was after 1.B?


edit2: I found E7976IMS.1C1 on another OCing site (but NOT on the MSI website.....), with a publish date of April 6th. Is that the Bios that enables OCing on non-k that pepinorang is referring to?

None of the Official BIOS will lock your Non-K CPU, don't worry.
When there is a Non-K CPU installed, BIOS will display an hidden option named "Beta Runner" in which you need to enable the option "NOC".
If this does not happen it means the BIOS is not new enough and doesn't have the feature implemented.

Canada Mundo says:

Thanks for the response; I'm relieved that you're still kicking around this thread. I'm doubly relieved that none of MSI's official BIOSes will gimp my CPU and install prohibitive microcode. I'm just a drop in the consumer bucket, but MSI has got my love for being consumer-friendly and keeping the OC non-k options alive.


Thanks pepinorang!!

Hi,,,
I have MSI Z170i Gaming Pro AC+i3 6100+patriot 8gb ddr4 3400.
I flash my board to bios 1.5 (official bios) and update to bios unlock non K version 1.61
and set :

OC explore mode = expert
Beta runner = NOC
BLCK = 108
XMP = Enable (first) ,,, and try Disable (2nd boot)

vcore = 1.145v
ram = 1.35v

more detail on picture .....


upload pictures free


i play game etc it's normally
but when i restart my pc the case is :

1. blck is back to 100
2. set to xmp (it is read only 3333 = my default ram is 3400)
3. and try to all setting the bios just same as like i did before ..... it's always back to default blck 100.
