I am the user that reported the cold-boot issues when increasing the multi on my QX9650. MIS sent me two beta bios' to try, but they only made the problem worse. With the beta's, my Logitech G15 (rev 1) keyboard would not always initialize. I would have to wait until Vista loaded, then unplug it and plug it back in. Plus, I had a hard time cold-booting with them, even when using the stock multiplier. If I stay with the shipping bios and leave the multiplier alone, the system is 100% stable.
