Is it possible for me to change settings manually to make my memory run at 1600? If so what specific settings need to be changed? My system detects the timing (9-9-9-24) correctly, and it is running at 1.5v by default if that helps at all.
With that MB and CPU you should be able to run 1866 memory without overclocking. So 1600mhz should
run just fine.
There have actually been quite a few posts here with the new AMD CPU's not running memory at rated speeds.
Have you checked for a newer BIOS?
It might be worth calling gigabyte with this and see what they suggest.
