SSD Caching Setup Issue

[Zelinn]

I'm having trouble getting my new SSD working as a cache.

I have the latest version of the RST utility, latest raid drivers, both my OS HDD and my new SSD plugged into the Intel SATA ports on the mobo, I have my bios set to raid configuration, and I edited my registry setting to enable raid as I am adding the SSD to my existing W7 install. The problem is, when I open up the Intel RST utility, it shows both my drives as 0gb and all the ports as unknown and am I unable to set them up to cache, the accelerate option doesn't show up at all. Any thoughts as to why this is happening?

How big is the drive? Intel SSD caching doesn't work very well, and if it's ~60 gb or larger it's generally better to manage your data yourself.
I don't think you should be in RAID.

It's a 64gb Crucial M4, I've read the mixed reviews but decided I want to try it for myself as I really don't want to reformat right now. When I set it to RAID it gives me the 0gb drive sizes, when I set it to ACHI is gives me the proper drive sizes but still doesn't give me the option to set up caching and I had read in a guide to set to RAID.
