Drop ratio to 8X and test 450 and 900 on the ram... set TRFC to 55 are we talking PC6400 ram here ?

CAS# Latency: 5
DRAM RAS# to CAS# Delay: 5
DRAM RAS# Precharge: 5
DRAM RAS# Activate to Precharge: 18
RAS# to RAS# Delay : AUTO
Row Refresh Cycle Time: 55

If the pro overvolts the ram as the E or dlx does plz set 1.92 for 2 volt operation...

Also which videocard ? PSU are you using ? and really aim for 3.8-4ghz or such that's already enough for an E7200...
