After the first time i loaded the system, i forgot ACHI, so did a fresh install..
I loaded optimised defaults, then enabled ACHI. I plugged my OS drive to the intel sata 6G/B.
I am using Revo uninstaller to remove all gigabyte programs(except chipset drivers). then starting off fresh.
Don't get me wrong, this board is great and looks even better. 4.4 GHz and very stable for BF3 and COD4.
Futuremark vantage 11295 was my score without the "twin turbo mode".
I hope these loading issues go away.
Thanks for your help. I will advise if i find the problem.
