With 21x190MHz (3990MHz) I'm able to POST, boot Windows and run a wee bit of Prime95 before a BSOD turns up.
If I try 19x200MHz (3800MHz), the system won't even POST. Black screen, not even a beep.
How come? What is limiting my FSB? Can't be the CPU, since it's actually running at a lower speed when I try 19x200MHz, right?
