Limitations of the X99 chipset

Mulder · Sep 14, 2015

Hi all!

At the moment I am running a 4690K and I am very pleased with its performance. However, since I really like the X99 platform and read many build logs on people succeeding, I was wondering what the limitations of this platform are in combination with Clover and OS X. I read that speedstep is not supported, but are there more things not (completely) supported, or any other things I should know? I would really like to get some input on this.

I have been unable to get past the low memory issue with the latest builds of Clover and Yosemite.
Can't boot past the Aptiofixdrv error unable to allocate runtime space...
Tried with both Aptiofixdrv and Aptiofixdrv2 and neither work. Found a possible replacement on the net, but, while using it allowed me to boot, it resulted in no graphics.
I do not know if this is just the Asrock UEFI has a problem with low memory area or if it is X99 all vendor wide.
Check the user builds, but I am stuck on Legacy mode with UniBeast Chimera on mine for right now.
Works well with Yosemite so far, but no power management and I never got the on-board audio working.

EDIT: Idiot me - solution to problem staring me in the face: If UEFI + Clover has a low memory area problem and the problem is the UEFI, then download the latest UEFI from Asrock and install.
Same Clover + El Cap GM I used on the X58A booted right up with the addition of npci=0x2000 slide=0 boot-args and is installing right now.

EDIT2: Duh - the X58A ElCapGM USB was Legacy Clover and crashed half way thru the install - still no UEFI boot on X99M Killer either.

Thanks for your reply! And it is great to hear that you finally fixed your memory problem

So if I understand correctly, the only thing that does not work is power management? Neither for the CPU or the motherboard? Also audio will never work, or only in your case?

Never tried to get audio working - just trying to get it to run with UEFI booting.
Have proven it will run OS X Yosemite 10.10.0 in Legacy mode, and everything works except power management. Fresh install 10 10.10.5 did not bother with audio.
What I am trying now is getting it to boot OS X UEFI so it can dual with Win10 booting UEFI.

But do you think that is the fault of your motherboard? Since I read many build log's with Gigabyte motherboards which did work properly with UEFI.

No, I think it is more a problem with Clover and the offset/memory block allocation. Will soon be trying it with the latest version of Clover 3264 or later which includes Rehabman's 128Mb offset + his version of FakeSMC. I am hopeful this will result in success but have not had time to put it to the test yet. Will post back with results.

Yep, definitely not a fault with the mainboard. Created Yosemite USB with Clover v2.3k r3269 created with CloverGrowerPro.
This version worked like a champ and it made one of the smoothest installs I have seen yet on UEFI.
All I needed was npci=0x2000 and cpus=1 (I added -v so I could see what was loading and dart=0 so I did not have to disable VT-d in UEFI).
Booted USB, selected the installer, it booted to the install screen, I formatted the drive and away hit the install button. No input needed until it rebooted on its own, then select the install icon and hit enter. Again, no input needed until it rebooted to the language screen.

Now to clone this drive and see if I can download ElCapGM and install as on a Mac.

Very cool, good news. New ASRock bios may have helped... Also the Clover HaswellE patch probably would have eliminated the need for cpus=1.

This is one of the fastest PC-Macs I have ever built. Can't wait to get everything set up and run some benchmarks tomorrow. I can't believe how "snappy" it is. Click on something and it is open almost as soon as you lift the finger off the button.

Just gotta love it huh? haha.. If you're gonna dual boot that box with Yos and El Cap you'll probably going to want this is your config:

PHP:

<key>BooterConfig</key>
        <string>0x28</string>
        <key>CsrActiveConfig</key>
        <string>0x01</string>
