ROG great product as always Asus and there at RDV ... I'm bluffing Apart from that speed to Install hand against the system not recognized in bios in UEFI mode, I had to start on my old SSD partition the ROG, disconnect DD except my other former SSD and ROG, I start with my iso to run my zalman Install Windows 8.1 Pro 64bit then I could install my iso on the ROG, I try to install iso by unplugging all Rog just drives the plug into UEFI had a error message that Windows could not be installed on the SD I did this manipulation is Nikel everything works Get instant start also opens very quickly. prices rise but very worth the money .. I suggest wait for the new ROG who will soon leave to the model I find it less and less .... I connect on a Asus Rampage Extreme Edition black socket 2011 ..............
