Hello,
Followed your instructions, and clover went on like a dream.
I have a near identical configuration with the exception I am using a core i5 proc.
However, I got a kernel panic and a reboot within moments of starting OS X.
The fix is to jump into Terminal from the recovery mode and running your post install commands (but omitting sudo) from the bash command
rm -rf /Volumes/<your OSX Volume>/System/Library/Extensions/FakeSMC.kext
touch /Volumes/<your OSX Volume>/System/Library/Extensions/ && kextcache -Boot -U /
Once I rebooted I El Capitain would continue to install.
