try running the ram at normal 800 mhz and see if you can get 5-5-5-15 since those are the stock timings. plus gotvoltage has posted that running unganged should allow you to get better memory timings. http://www.xtremesystems.org/forums/...&postcount=522 then run some benchies and see if your current memory speed or the better timings would help. the cpus normal voltage is 1.232 volts. trying messing around more with the multiplier if you want to get a better overclock. also you might have to give the cpu more volts if that is the highest you can get right now.
