You need to check this with our tech suport: https://register.msi.com/ Either you have compatibility issue or defective VGA, best is to check with them, they will help you out. BTW, I found retail i3 6320, but Z170 KRAIT GAMING sample is not available at the moment, I have to wait my turn.

Does it also happen with MP BIOS or just with Non-K BIOS?

What do you mean A7 variant? Anyway the BIOS versions posted in this thread are all we have to offer for Non-K OC.

Does it happen with MP BIOS? Seems more like a VGA issue than BIOS, what VGA is this?

Can you send me all the information below to investigate? - ALL the components used (if possible include full product number) - OS version - Games used during crash (Also which patch/updates installed if possible) Would that happen if just sitting in a game 24/7? Would that also happen if running 3D benchmark in loop such as 3DMark11 or Firestrike? I'm sure you would understand we can't reasonably play games all day/week. Thanks! @vdelvec is also running a different G.Skill 32GB kit @DDR4-2666 and don't seem to encounter this problem as far as I know. So we can surely figure out your issue, replace the whole system seems a bit exaggerated.

Long time I didn't update new BIOS here. MP BIOS 140 and BETA BIOS 152 posted in first page.

Can't believe 83 ppl saw this without even replying to you... From Elmor's thread (http://forum.hwbot.org/showthread.php?t=149907):

I don't know what is your problem, I tried two Z170 KRAIT GAMING and I didn't see any issue. You can clearly see IT WORKS on my screenshots but I'll find a retail chip to convince you!

My ES are same stepping than retail so no difference. Furthermore these CPU don't have BCLK unlocked with normal BIOS... However I will try to find a retail i3 to show you it works perfect here.

Wait few days, I'll post a quick guide for Non-K OC. "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.

No official support from either Intel or MSI and no further development from our side so far. 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.

Interesting... I'll have to test that! Thanks for your feedback anyway and enjoy your clocking!

You can't ONLY setting bclk with those BIOS you will also have to set up memory frequency and vcore manually!

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. Max BCLK Straight Outta BIOS on Z170A GAMING PRO CARBON (no external clockgen on this board): http://valid.x86.fr/5vk7r5 Max BCLK Straight Outta BIOS on Z170A GAMING M5 (with external clockgen): http://valid.x86.fr/cr64m8 Nice and cheap GAMING boards for 24/7 setups.

You mean you need more volts to pass 32M than to boot right? So far, I only tested two kits of B-Die very quickly as I needed to return those same day I got them. Both kits could pass 32M at 3866 12-12-12-28-220-1T with auto subs. Both kits needed about 1.82v to POST and load WinXP. For 32M, G.Skill TridentZ needed 1.88v while Geil Dragon needed 1.92v. Here is a dirty 32M I did then (Don't blame me for the eff, it's just a one shot on fresh untrimmed/untweaked XP, Lsc1, Maxmem, Waza, all subs auto besides tWR 16 and tREFI 65535):

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...

What type of IC? Never saw that... Envoyé de mon GT-I9500 en utilisant Tapatalk

HOT is based on 143, no change for MFR/D-Die/E-Die/B-Die it only improve AFR. 3866 1T with E-Die is easy here but for 4000 I have to boot at 99MHz bclk then +4100 is fine. Same for 3866 with B-Die, need to boot 99MHz.

Not sure why the date isn't the same, anyway here is the file I used to flash the Z170 KRAIT GAMING (uploaded from my USB dongle): http://we.tl/kydog6UPbK

Download again, it has been updated. I checked and B5T is present in the link.

B5T I use is from the link of this thread... Envoyé de mon GT-I9500 en utilisant Tapatalk

I've been playing with the Non-K OC BIOS for XPOWER. 400MHz BCLK straight outta BIOS, all aircooled. 1.35v PLL OC / 1.65v ST / 1.65v ST V6. http://valid.x86.fr/qp0h6l

Any kit validated on the QVL list means it passed more than 100% Memtest with stock settings and XMP profule. I will check what BIOS version was used for this and will test both kits for you next week. Envoyé de mon GT-I9500 en utilisant Tapatalk

I will try that today and get back to you asap.

If the board does not have an external clockgen, 170MHz is about the max you can get.
