Gigabyte's upcoming beta bios for EP45 serial
has improved DDr2 bandwidth to DDR2-1333 and higher.
tip: load optimized,in MIT select divider of 4A(266A) or 4B(333B)
change vid to match your porcessor or leave it auto then, leave bios
if your D9GMH or D9GKX not stable or need to improving latency by PL
add more voltage both on Northbridge(MCH) & DDR2 voltage.
i'll update other bios soon.
