I'm upgrading to 8GB, and I'm looking at getting two kits of these OCZ 667 modules (5-5-5-15).
My motherboard is the ASUS P5B Deluxe Wifi Edition. In the description on newegg it states that the board only supports DDR2-800 modules. The OCZ modules listed above are 667. Do you suppose there could be a problem?
Also... this machine is mostly used for editing digital media, so I don't believe I need super fast timings. But could there be problems if I tried to reduce the timings on those modules?
