​ I recieved an order from Crucial for a 2G.B. RAM kit containing 2 RAM sticks 1G.B. each DDR2 PC5300 ! I installed the RAM to Dimm 1 and Dimm 2 leaving slots 3&4 with 512M.B. sticks in each slot also PC5300. My system booted up fine gave me a prompt that new memory has been installed and a option to press either F1 or F2 to continue ! I pressd F1 and it booted to WinXP . MY ? is did I install these new 1 G.B. sticks to the proper slots ,I thought I had read somewhere you are suppose to put the new upgrade in slot 1 and 3 ,however the reason I went with the two slots I actually thought they where one and three they both had black connectors at the end of the slot and the other two slots had white ends ,I actualy thought I was installing to 1 an 3 because the way it was setup on the System Board they alternated first slot was back the one next to it was white ,then a black slot ,with white on the last one (these are the color of the tabs that lock the stick in place) . Since my system has properly reconized the RAM ,Iam assuming I installed it correctly and untill Iam told otherwise I will leave them as is ! Anyone who has anything to add ,your suggestions or comments are welcomed .​
