What kinda problems with 4 sticks over 460MHz FSB?

And yes, as GrnFinger pointed out, I'm back on Bios 0505 because all my notes suggested it was the best bios thus far, and you know what, it is. Dividers work, FSB overclocks as far as newer bios if not further. I've had ONE, yes ONE, reboot since downgrading and I'm sure it was my fault for closing the window and letting the PC get too hot. This is compared to Bios 0907 with several reboots a day but can Prime/OCCT for 24 hours without crashing... :S

Oh, and this is all with lower voltage on CPU and Mobo than on Bios 0907...

Performance seems better too, Folding is as fast @ 3.6GHz on 0505 as it was @ 3.8GHz on 0907 for me!
