I'm not really familiar with your RAM characteristic.... what is it originally rated at?

Anyway...try this....

CAS Latency Control (Tcl) - 2.5
RAS# to CAS# delay (Trcd) - 03 Bus Clocks
Min RAS# active time (Tras) - 07 Bus Clocks
Row precharge time (Trp) - 03 Bus Clocks
Row Cycle time (Trc) - AUTO
Row refresh cyc time (Trfc) - AUTO
Row to Row delay (Trrd) - AUTO
Write recovery time (Twr) - AUTO
Write to Read delay (Twtr) - AUTO
Read to Write delay (Trwt) - AUTO

DRAM Bank Interleave - Enabled

DQS Skew Control - Auto
DQS Skew Value - 0
DRAM Drive Strength - AUTO
