>>1) I left the 256 RAM in the first slot and placed the 512 RAM in the second.

>>I thought the total would be close to 768 RAM.

>>But it was 640 RAM in My Computer Properties.
>>
>>sigh.....

>>So....

>>2) I changed them around. I placed the 512 in the first slot and the 256 in the second.

>>Still 640 RAM.
