|"one of my ram is 667 mhz other 550 MHz"|
When using CPUZ, the Memory tab will tell you the frequency ALL RAM is running at, the SPD tab will tell you what the individual sticks are capable of. 550MHz is not a standard RAM speed so something's not right. Could it be you have different speed RAM sticks paired up together?? When using different speed sticks, they do not run at different speeds - the faster RAM's speed is reduced to meet the speed of the lower speed RAM. Here's a couple of examples:
DDR3-1066 + DDR3-1333 = DDR3-1066 (@ 533MHz frequency)
DDR3-1333 + DDR3-1600 = DDR3-1333 (@ 667MHz frequency)
Try one of these to check your CPU temp readings:
"i shall install 32bit windows"
NO! If you do that, you will only be able to use 3-3.5GB of your total RAM. You need 64-bit to be able to make use of all 6GB.
