I've got the Striker II Extreme with the 402 BIOS installed to start with.
I thought that I would update to the latest non-beta version - 0602. Bad choice.
My PC would hang in windows at random times. I thought that this was down to my modest OC on my CPU (3GHz to 3.5). I put everything back to stock and still the random hanging in windows.
I then proceeded to installing the 0512 BIOS which I am on currently. This too is rubbish. I still get the same hanging problem, but a bit less frequent this time. I also get an even more annoying problem which is that it hangs in POST. My LCD poster tells me "mem test" and there it stays. I try a reboot - nothing, same problem, again, and again, nothing. Turn the PC on and then all my settings about the OC & memory etc are lost and during POST it tells me my memory is at 1T not 2T, my cpu clock is 1.8 not 3.5. Crazy.
I am trying to put it back to 0402, but this can only be acheived with AWDFLASH. arhhhhh! I don't currently have a floppy drive, or bootable USB key. Awaiting delivery of a USB key to make this boot disk.
However, I am finding this Mobo to be more reliable that the Striker II Formula, as I haven't been getting any Blue screens yet - touch wood.
I'll update on here when I downgrade to 0402.
