I've done a couple searches & can't seem to find any threads to help with my particular use case, so I thought I'd pose the issue/question:
On my Music Studio v2.0 build, I want to install a dedicated GPU to the build, and use that as my only video source. Basically - switch from HD 4000 graphics for my MDP Cinema Display to a dedicated GPU with MDP. I purchased the XFX Radeon Double D R9 270X from a local retailer. One of the reasons I went with this card is because a) it has 2 MDPs, and b) it supports 4K via DP and HDMI. I'm hoping that Santa brings me a new 4K TV or monitor for Christmas...I've been a VERY good boy.
Not wanting to mess up my working music studio build in the middle of mixing a project for my dad, I decided to "practice" with another box that runs Plex Media Server as well as Indigo Domotics. I keep a spare SSD laying around for such experimentation, so cloned the media server's working boot drive, and then installed that as the experimental boot drive. BTW, media server is GA-Z68MA-D2H-B3 + i5 2500K + 8GB RAM + Mavericks 10.9.4 + MultiBeast 6.5.0.
Steps I followed (still booting from HD 3000 - connected to 1080P monitor via DVI): 1. Changed "Graphics Enabler" to "No" in org.chameleon.boot.plist...then rebuilt disk permissions; 2. Rebooted & went into UEFI (v.U1c.. not BIOS): Set Init Display First to PCI, set Internal Graphics to Disabled. Saved & exited UEFI. 3. Powered off machine, then installed new GPU. 4. Connected monitor to DVI port of new GPU, then rebooted.
Results: POST screen displayed per normal, then when I'd normally see a little spinning cursor in the upper left corner, I now get 3 short lines of code, followed by a whole bunch of gibberish....and then I'm locked up : Of course after a couple reboots & getting the same thing, I changed it all back to HD 3000, and the machine boots up just like always. So I re-ran the process above, only to get the same results. Note: I do not even get to the Chameleon boot screen where I can boot in -v or -x safe mode. The machine locks up at all the gibberish.
Troubleshooting round 1: Could I have a bad card? Hmmm...not sure. So I dig out a Asus ATI Radeon HD6450 that I have laying around and swap it for the XFX R9 270X. BINGO...it boots up just fine. Then I think: Well, maybe because I get the gibberish before I even get to Chameleon boot screen, maybe there is something that is missing/not correct in Chimera.
Troubleshooting round 2: So I pull out the ASUS HD6450 and put the XFX R9 270X back in. Then I dig out my UniBeast install key, pop that in & try booting again. I'll be D*&$ED!! It boots just fine into the Mavericks installer. So there MUST be something sort of "vanilla" about the UB key that lets the boot process get past the point where things used to halt & display gibberish.
Again, all the searches that I did were about folks adding a GPU to the system & wanting to do multiple monitors with both HD 3000/HD 4000 *and* their GPU cards. But that's not my situation. So if anyone has an idea on how to get this to work, I'm all ears!
Thanks in advance for your time wading through the above & for your feedback!!
