No. Not if you didn't change anything. You should try some openCL benchmark to verify openCL performance. If numbers are abnormally low or the app crashes or give errors, you know that openCL is broken. If you have a windows install and benchmarks are similar there too, it could point to faulty hardware. If you don't have a windows install, you could try installing OS X fresh on a different drive. If the problem persist on a fresh clean install, then it could point to a possible hardware problem but could still be a software issue. If the issue is not present in the new install, then it points to something faulty in your current install.

Today I try a new clean install, the problem still here. So I replace my new 980ti by my old 770 (like my old config) and the problem still here, so i think it's a software problem... I also try to uninstall and resinstall nvidia web drivers, same thing...
Edit : I launch an old drive backup of yosemite (with clover on) and it works. Do you think i could be DSDT or SSDT related ?

I have tried doing this install multiple times and every time I get the same result.
I boot to the clover screen fine, then when I try to go further, during the verbose boot it shows this line:

000010.720661 AppleUSB20HubProt@1d140000: AppleUSBHostPort::disconnect:: persistent enumeration failures

It hangs for a bit on the line above, then it goes to the line below..

[IOBluetoothfamily][SearchforTransportEventTimeOutHandler] -- Missing Bluetooth Controller Transport!

It hangs on the line above for 30 seconds to a minute and then the screen goes "strange"(some of the words become unreadable) and a "no entry" sign appears in the middle of the screen. The screens flashes every minute or so and blank line is added below the last boot line.

Hope this all makes sense. I haven't installed OSX onto PC hardware since my Gigabyte GX58 UDR3 board...
I am lost, please help!

My specs are:
Rampage 4 Extreme - bios 4901
Intel 3930 cpu
Ripjaw 4 x 4GB ram
MSI GTX 970 4 gb.

Any help will be great appreciated, Thank you!

I'm trying to install El Capitan, I have attached a zip of the clover folder.
Really appreciate the help.

Thanks you for your reply.
I really was hoping you would find an issue in that folder... oh well, back to the drawing board.
My boot settings are exactly as you have outlined in your guide, I have tried to boot so many times I've lost count.
I have attached shots of all the changes I made to the bios after restoring optomized defaults..
As far as I can tell these are the exact settings you outline in your guide, unless I am missing something.

After it not working multiple times I tried a view variations, namely:

on the onboard devices page:
1. I have tried disabling the bluetooth controller(as this is the line it always crashes on)
2. different setting with ASM1061 controller, including disabling it.

On the Advanced USB configuration page:
1. I tried disabling Legacy USB3.0 support
2. The hilighted line in my pic (Sandisk) I tried changing that from auto to "forced FDD" and "hard disk" neither worked.

CSM page:
1.I tried setting it up as you suggested for an older GPU, just as I wanted to try anything and it didn't work..

I think that covers everything I have tried.
Thank you so much for all your help on this, it is greatly appreciated.
Lastly could it have anything to do with RAM modules?? I have all 4 of my 4GB modules in.
