2) iF I SWICTH DIMM 'S CONNECTIONS ( NO DUAL CHANNEL ) MY DRAM FREQUENCY CAN UP TO 200 MHZ ?
3) IF I REMOVE 2 OLD 512 DIMM CAN I IMPROVE PERFORMANCE?
 
1) Go to the BIOS to set the RAM speed to 200MHz, check the manual to see how to. Or you can let it runs in 160.6MHz. For some of RAM, the manufacturer always set the RAM to run in the lower speed for safety reason, and you have to go to the BIOS to set the speed.
2) Maybe not, but you can try.
3) No.
