So I have 6GB of DDR3 RAM in my computer, and when I go into my BIOS, it says that they are operating at 1066 frequency, when they are 1333 sticks. I'm not sure how to solve this issue, but I think I know how it came about. I had a 2GB 1066 stick in there and for some reason when I took it out, the speed stuck in the BIOS.... any ideas how to correct this? I have tried: Flashing the BIOS. I think I might try to clear the CMOS THEN flash the BIOS, and hope that that works.
