Maximus Formula BIOS 1403 made system unstable

[meister T]

Since updating BIOS on Maximus Formula to 1403 reboots result in BSOD and ASUS support told me to ask you for the timings to run this memory on this board. F2-8500CL5D-4GBPK PC2-8500 DDR2-1066 CL5-5-5-15 240PIN Dual Channel. If I run at these timings I get random BSODs as well.

Below are crash reports.
