I am testing the mod on my M9A with i3 8100 and I'm stuck with 18 post code, tried BIOS 0094 from Alex, now trying modded MXA 1602... 1602 does not work with XP?

There is quite long (3-5 secs) 00 code after 55 which might be misleading, there were couple reboots, but I'm in OS now non-K OC is not that fun anymore although

Update - I could OC and play with mems, but cache multi is stuck at 33 no matter what, and turboV core throws an exception when I switch to clock tab. Got a decent geekbench and xtu result, but mocf beats m9a since it clocks cache.

Update #2 - in my case if I apply too much oc, it fails with post code 15, after which a reboot is stuck at 00. It's fixed by powering down completely (unplug psu and wait 30 secs) before next attempt.

Has anyone tried this mod with an M8i?

@arnavvr Yes, a few people have. There is a mod bios available on the Maximus VIII page.

I don't think the 6 and 8 core CPUs work on M8i even with the mod.  I could only get it to boot with an i3 8350k.

@sabishiihito Did you do all of the same pin mods that you would need for the Apex? Pin short and isolation. From here it appears that 6 cores do work:

All 6 Core are working fine, even 9900k is posting but freezes at the splash screen.

I couldn't get 8700k or 8086k to boot on M8i with the Coffee Lake BIOS.  Any special instructions other than shorting the two usual pads together?

What is happening? Nothing after pressing the power button or does it start for maybe a second and then shuts down?

If nothing then try to redo the pin shortening, if it starts and immediatly shuts down then there is something me related wrong.

I know the pin short is correct because the CPUs work on MOCF and IX Apex, but last time I checked the ME was showing 0.0.0.0 with the 8350k so I probably need to re-flash.

For MOCF and Apex there was another method to do the pin shortening, maybe you did that and didn´t know about? ME 0.0.0.0 is fine if you can read this in bios. Only if you open the rom with a tool like mmtool then there should be a hint to the ME version before cleaning.

And as far as I know pin mod is only needed for 6 core. 8350k is more kaby then coffee lake.

Hi there. Any of you here have flashed your apex 9 onto z370 bios already? I have a small request:

 

Can you please run for me (as root user) the following script, under linux?

 

ls-iommu.sh

 

https://gist.github.com/jabbas/a8785710a5e8655045fc0be67385e887

 

If you are on windows, then please boot of a linux live USB. Which can be burned from ISO disk image file on windows using the program rufus. For example ubuntu

 

https://www.ubuntu.com/download/desktop

 

This is to check / see the IOMMU groups. For virtualization passthough under linux. Thank you.

Anyone have any luck doing this mod with the Maximus IX Code? It appears to me that the board is physically different than the Apex and hard modding it will differ from the Apex as well? And I assume that the bios files are probably not interchangeable between the two and I'll need to create a proper file somehow?

I'm having an issue overclocking with the 0094 bios on my IX Apex and a 9600K. No matter what ratio I set in bios, above the stock 43 multi,  it doesn't show in windows. I can down clock the cpu no problem but I can't even get 44 multi to work. And the settings stay saved in the bios but only shows stock clocks in windows. I might be a complete noob and missing something but I don't think so. Hopefully someone can help with this weird issue.

Just wanted to add that the bios seems to work fine otherwise.

Try to set performance boot mode = turbo in BIOS and on top maybe leave speedstep on, I had similar problems with an asus bios for apex x lately

Hey websmile, tried both settings, independent and together, still no improvement.

As websmile said, if you set boot mode to turbo and leave eist and turbo enabled it will work.
But you have to set cores 5 and 6 in OS using Turbo V core 1.01.15
On screenie below I set 50x multi in bios but it boots at 43x until I change cores 5-6 under cpu ratio tab to 50x/50x

Hey Guys, Normally I don't ask, "I work with it"  but I'm having problems with slipstreaming XP for my IX Apex   Does anybody have a XP ISO I could download?

@techjesse try ROG Maximus VIII guide but use Z270 AHCI driver on Maximus IX Thread should work, without read Maximus VIII Guide probably you wont get it why not working

Thanks, I'll read and work at it.

Forgot to add something, i mean OCGuide on Maximus VIII Thread, because there is no USB 3 driver for XP.

After I'm done with the i5 7600k Ln2, I have a early Christmas gift to mod and bench

Exactly. The 0094 is not able to adjust the cores in bios properly. However, turbo Vcore works fine. 

There is a hint for modding bios regarding correct core count with new coffee CPUs in win raid Forum if somebody cares  

Tested with 9600K and 9700K.
