Now I'm confused too! Lol. I was under the assumption that the sata parts 0-5 were intel controled, and the Sata 3 ports ( 6-7) we Marvel controlled. I'd only get blue screens when attaching the OS drive to one of those two Marvel ports ( 6 or 7).
Haha, what's going on? We don't know
OK, you want it on the first Intel port (SATAII_0 blue against PCB). You had to have been using or testing it on the Marvell controller (GSATA3_6/7 White), otherwise you shouldn't have got the Marvell error BSOD (mv91vv.sys). If you are not, and were not using those ports, that is VERY ODD and would sound almost impossible... unless maybe you have loaded the Marvell drivers possibly(?) Not sure if they can cause error being loaded though without being used.
So just double check everything, you want your SSD on the Intel ports, using Intel drivers, preferably on the first Intel blue port at the top of the stack under the white ports, against the PCB.
Hope that helps!
*Edit*
OK, I see! Sorry, I just re-read everything, and now I see you were indeed testing the 6Gb/s ports. Sorry about forgetting, I did read your original post the first time I commented, but just must have forgot after that.
So ya, those are the cause of the error, and the Intel ones are faster and more stable anyway, so stick with Intel!
