try what I may, new install, best I can get out of new mobo for my raptor\n(WD 36GB with only Vista on it, page is on another spindle; same with or\nw/o readyboost) is 5.5 . plugged it to different positions, even Gigabyte\nsata controller - same. Any ideas? old was ICH9R, this is ICH10R. Latest\n(only) chipset drivers - just reinstalled. WD diag shows nothing wrong.\nSMART shows fine.\ntia!!!
