[Guide] El Capitan on the Skylake H170N-WIFI

[SpitUK]

Sorry it hasn't worked for you.

Yes, I just put the CodecCommander kext from the distribution zip on the desktop and ran KextBeast. This should put the kext in the System/Library/Extensions folder and repair/rebuild. You don't need to put it in the Clover folders.

In earlier days you had to check your audio ID and modify a number in the internal plist file to get it to work. Maybe worth checking the older method out (it's in the Forum).

I had problems getting sound to work at all at first, until I used IORegistryExlorer to discover the Audio ID and then enter that manually in the Clover Config.plist. MultiBeast couldn't do it.

As for Power Off. Hmmm. You have a very similar PSU to me (CX500M) and a similar motherboard family. You'd think they'd work much the same. Trying to think this through, it occurred to me that perhaps the Shutdown "code" was being misinterpreted as a Restart "code". Is this what Clover Configurator is trying to rectify with FixShutdown?

Certainly a lot of people have this problem with Skylake boards but I have seen no in-depth explanation or solution. Really frustrating.

Finally maybe it's worth me listing the config.plist edits I did -
Skylake APIC fix
USB Port increase 15-30
ACPI audio HDAS to HDEF fix
and then the Audio ID insert.

Hope you can work through the problems.

Thanks. The other issue I have noticed is the RAM speed is 3200MHz on About the Mac. In the BIOS it says 2133MHz. I did what it said for clover and edit the ram profiles but nothing has changed?

Also, what graphics card do you have as I am getting some stutter on Warcraft and benchmarks?

Does my Clover look ok:

Does my Clover look ok:

Change XMP from No to Yes. Save Reboot and check to see if RAM frequency is correct.

Still the same...

Just checked in the BIOS and it says the memory is at 2133MHz. Tried with XMP in clover and without and just tried again to input the values manually in clover. Still says 3200MHz. Strange.

Doesn't seem to be affecting stability.

Anyway of checking whether my CPU is using turbo correctly?

How do I enable trim on my Samsung SM951M.2 drive?

Yes, your Clover Config looks ok - there are just two differences between it and mine.

1) On the Graphics tab I have "Inject Nvidia" ticked as well as "Inject Intel". I needed this to get accelerated graphics. I have an EVGA GT740 SC GDDR5 card and a moderator - SlimJim - mentioned that 740 GDDR5 cards needed the Nvidia web-driver installed to be recognised correctly. From your latest screen-grab though, yours seems to be anyway.

2) You haven't included Piker Alpha's AppleAPIC config edit (in the Kernel and Kext Patches tab) whereas I have. I read that if you are using 10.11.4 this is not needed so you are probably fine. For me, my UniBeast stick is only 10.11.1 and so I needed it to install. I then updated to 10.11.4 but left the patch in place.

As for memory speed - yes, I had this problem too. The Gigabyte H170 boards are spec'd as DDR4 2133 speed only from what I can tell but mine showed as 3200 too. To be honest this problem cured itself once I had all the kexts and patches in place.

If what JBamford mentioned didn't help there is yet another config-plist patch that might work. I tried it but it didn't. As I say, the problem cleared itself once all my edits had finished.

P.S

I haven't got an M.2 SSD only a Crucial SATA 128GB.

I used the Terminal command: "sudo trimforce enable" and that did the trick.

Is Clover up to date? To enable TRIM open terminal and type sudo trimforce enable. But note that enabling TRIM can cause issues with some SSDs.

Clover can't read DDR4 settings correctly. You have to set the RAM settings in the SMBIOS section of the config.plist.
