And for the record, the mobos are supposed to default to 5-5-5-15, to ensure RAM compatibility. Then you just change it manually to whatever the RAM is rated for (ie-4-4-4-12, etc). Alot of people post " WTF? My RAM I bought is 4-x-x-x and BIOS shows 5-5-5-15?!?!?!?!?!"
It's supposed to do that
Now, pay it forward
