I have the same board and it's been fine with Yosemite. I still haven't been able to get iMessage working, but that failed under Chameleon/Chimera too. It was a little bit of a pain to set up, and some things that were easy (boot resolution for example) are more complicated. But the core of it was tons easier once the majority of it was set up.
Really? You have GA-Z87X-UD3H too? That's amazing! I'll definitely try Clover this weekend!
Could you tell me where did you refer to? I'm gonna take a look at the link below.

If you know any additional information, any small help would be appreciated. Thank you.
I have the Z87MX-D3H as well (and have been freezing in Mavericks randomly).
Can you tell me what boxes you ticked in clover setup? What Bios version are you on? Did you install over your existing Mavericks, or did you do a clean install of Yosemite?
Also are you running an overclock? If so what GHz? What is your RAM? (slots taken, amount, brand), and what Memory Profile are you usingin Bios?
Reason I'm asking is because I want to copy you This freezing has caused me to stick to my windows drive exclusively for the last few months, and if I could fix OS X to be fully stable I'd be one happy camper!
