For what it is worth, I have spent a whole day trying to install Windows 7 Pro on a very recently acquired Gigabyte Z97X-SLI using an OCZ Vertex 2. I am using an Intel Core i7 4790K, 16GB RAM
Eventually I contacted the supplier to be advised NOT to try using the OCZ Vertex 2 because it is incompatible with the Z97X. I therefore used an ancient WD740 10k RPM drive taken from a retired server.
Joy of joys, it works!
May just be chance but I had previously tried using two different OCZ Vertex 2SSDs so my guess is that they don't work.
Your mileage may vary
