I've just assembled a new computer , with Windows vista ultimate 32 bit , and i have 6GB DDR3 RAM.
The problem is that windows doesn't recognize the whole memory i have , only 2GB ? while in the computer start up i see the whole 6GB
how can i fix it ? do i have to changemy OS to Vista 64 bit ??
Yes, you will have to change your OS to 64 bit. 32 bit can only recognize certain amounts of ram. It can only use the 1st channel on your board efficiently for ram as well. the only way you can get your board to recognize that ram, is to switch to 64 bit. Hope this helps.
