Memory Question

thanks for help guys

Dual channel is different with every board manufacturer.

On some boards you have to put two sticks in the same color to have dual channel.
On other's you have to put them in the different colors.

Check the manual when in doubt.

You should only be running the 2X2GB sticks in slots 2 and 4 because they get the info from the CPU first. You should not be mixing Ram sets, it's never a good idea and usually will cause HDD corruption or just general instablity. The 680i has it's dimm slot colors alternating so use the same colored slots for your Ram. Use the Black slots only for 2X2GB. Do not pair them side by side as someone suggested, that is incorrect.

My memory score is 7.5 running 2X2GB of GSkill pc2 9600 at 1200MHz.

My Memory Score is pegged at 7.9 with a transfer rate of a little over 25k MB/s I'm not sure how fast you need to be to peg out at 7.9, probably around 10k somewhere. Those numbers are kind of wierd anyway. I just use the built in command prompt ":\winsat mem" to fine tune my memory.

What is the current Mhz of your memory right now? I know when I had my quad core running at 3Ghz and DDR2 800 4-4-4-12 memory, my speed was only around 5k MB/s so you aren't too far off.

What is your CPU speed and Memory Speed? I see the latency is 5's compared to my 4's. and memory usually doesn't run at 800 Mhz by default, uaully it is 667. So if you are running 667, latency 5's then most likely your MB/s is correct.
