No one willing to give us any suggestions on where to start? I tried working my DDR latency, default is 2.5, lowered it to 2 and bandwidth (Sandra) went down slightly, and it won't post at either 1.5 or 3.
Dunno what to try now, but I gotta tell ya, I am tired of resetting my CMOS. lol
What I noticed with your setup is that your default settings are not what they are suppose to be. The XMS3200LL should give you;
ADVANCED CHIPSET FEATURES
DRAM CLOCK/DRIVE
CURRENT FSB FREQUENCY = 166
CURRENT DRAM FREQUENCY = 166
DRAM CLOCK = 166 <--------- This will not go 200 on the 5:2:1 RATIO
DRAM TIMING SELECT = by SPD
CAS LATENCY TIMING = 2
BANK INTERLEAVE =
ENABLED (set this manually)
PRECHARGE TO ACTIVE (tRP) = 2T
ACTIVE TO PRECHARGE (tRAS) = 6T
ACTIVE TO CMD (tRCD) = 2T
DRAM ACCESS = 2T
ENHANCE DRAM PERFORMANCE =
DRAM COMMAND RATE = 1T
WRITE RECOVERY TIME = 2T
DRAM tWTR = 2T
You say you drop performance when you set things to CAS2, that's odd since more often than not it should go up because of the lower latencies. Would you like to try more voltage? Running at 2.8V is the maximum voltage as defined by Corsair & going beyond this point you will void your warranty. Sometimes with a board that is stubborn at times you need more voltage.
SOFT MENU III
CPU OPERATING SPEED =
USER DEFINED
CPU FSB CLOCK = 180
AT YOUR OWN RISK
RATIO = 5:2:1
MULTIPLIER FACTOR = 12.5 (if you want to check for maximum FSB drop the multiplier low enough so that you don't beyond default clockspeed)
ENHANCE FOR BENCHMARK = ENABLE (I leave mine that way)
POWER SUPPLY
CORE VOLTAGE = 1.75V
AT YOUR OWN RISK
DDR VOLTAGE = 2.75V
AT YOUR OWN RISK
CPU FAST COMMAND DECODE = Normal (for anything above 166)
This is a mild overclock I would think & again it's
AT YOUR OWN RISK. I would expect that you have enough cooling & a proper PSU to handle the heat & power. If you have a ATX2 connector, that 4 prong 12V connector, plug it in the MoBo as the VCore is being drawn from the 12V line in these new boards unlike the older ones that took its power from the 5V rail.
Clearing the CMOS should be second nature by now.
