Panic CPU ? What the hell is that ?

[short]

You can't combine the two kinds of RAM, they have different timings. It's possible to mess up your mainboard when doing this.

Ok. That's probably the cause of the Armageddon then. I'm gonna sell those incompatibles ones and take the same ! If that's the problem, OH MY GOD, I'm ****ing relieved.

edit : and by the way, thanks so much for your time guys, this was a ****ing nightmare…

Hey, I have the exact same problem. I wrote about it in a build thread here.
My latest post contains the information I could gather by troubleshooting but as you can see the problem is still present.

.....What MAY be the problem: bad graphic drivers (NVDAResman and NVDAGK100Hal)....

Removing all native graphics kexts and installing NVIDA's web drivers helped me get past the KP "panic(cpu 0 caller 0ffffff80003d155a)..." on 10.11.2. However, the only available res SP shows is 1024x1280
