I had read some where to crank it up to 125 for the 8800gts 512 which I have and it will get better performance but, these boards obviously won't handle it. I was having issues with my Raid0 dropping as well so, I went back to just one 250gb drive and a 500gb external. I shot a couple of pictures to post here after slicing my damn fingure open bad,,, cutting the wire ties. I will post it in a little. I have a pretty sweet setup. I kept dropping my damn raid with 2 new western digital retail,,, 250gb 16mb chache drives that I bought, I'm pretty upset about that because I have never had any issues out of my old config of a 250gb and a 160gb in raid0 same company western digital and I get two new identical ones and have hell getting them to stay in array.
