Anyone have a SATA III controller they know works well with the C300. I have an AsRock H67M-GE board and the AHCI drivers included don't seem to work well at all. I can't find any updates on their website.
turn off writing cache buffer option on your ssd in device manager
YES! YES! YES! Thank you. It took me a really long time to reply because since I started this post I ran into a plethora of other problems. (Had to RMA CPU and go through the whole cougar point swap, and then RMA CPU again!) Anyway, I finally got all the rest of my hardware going, but ran into this problem again. Came back to this post, turned off write cache buffer, and it was like a miracle. Computer is finally running great after only 3 months.
