I've got this weird problem with an online friend's new build. He got himself an Asus M4A77TD Am3 motherboard, 2x2 sticks of OCZ D3 1600mhz CL8. Also a new video card and psu. This thing won't post with both sticks in. If he puts them in separate channels, it posts. With one stick right now, the system is running perfectly. I saw a bios update for the mobo that dealt with a particular brand of ram not posting, so I got him to flash to the newest version. Still won't even post with both sticks in the same channel. I got him to try both the blue and the black slots, it just won't post! I haven't really dealt with phenom type systems before so... am I missing something?
