Quite right, I heard that some of the modded bios fixed them on the P5Q which was the only reason I got my hopes up a little. Still, the P5Q-D seems to go well at 457*8 which was a lot harder to get on the MIIF. Havent even bothered with gtls, mainly because I haven't tried to work out their equivalent from the MIIF settings. Would moving +/- 5 mv on the MIIF be the same as x0.635/x0.625 (given that x0.630 is standard on GTL0/2)?

It is indeed frustrating to spend this much money on the MIIF only to discover Asus' support is getting very shabby. I'll probably go DFI or Gigabyte next time around, but that won't be until I think about going i9 or something better - I've spent far too much money & time on all this and must use my PC more I've gotta say that new Foxconn P55 board looks mighty sweet though!
