i chose a mobo gigabyte GA-H61M-S2P-B3 .. i was about to buy 4gb ram (2x2gb) as it has only 2 ram lots i thought that for future upgrades i can't insert one more ram as the two slots will be filled by 2x2gb ram's..so i decided to get a single corsair 4gb 1333mhz ram ..does the dual channel memory is very important or a single channel memory is enough .. because currently most of the games use 4gb ram so after 2-3 years i can insert one more 4gb ram if i insert a single 4gb ram..is 4gb ram relly enough for gaming for 4 years from now..
Single channel memory will be slightly slower, but you can't notice it unless you run benchmarks. Are you sure that the same 4 GB module will be available in a couple years when you want to increase to 8 GB?
i will run all games like bf3 fifa 12 nfs the run etc..some times i will do antivirus scanning and browse the internet or convert some videos and browse the internet ..does a 1x4gb ram suits for these purpose..
future proof..my mobo has only two ram slots so 1x4 gb will free up a ram slot and i can add an another one after 3 years..and one doubt my friend installed a single 4gb ram in a windows 7 32 bit os it says only 3.25gb usable then what about the remaining ..
yes that 10$ makes a difference for me and a single 4x1 gb ram costs less than a dual 2gb ram..then if i install a 4gb ram should i install 64 bit or 32 bit os..because in 32 bit os only 3.25 gb is usable is there any disadvantage using a 64 bit os..
you need to have hardware to run the 64 bit os but yes if you want to use more than 3.25 gb of ram you'd want a 64 bit os.
64 bit os allows you to run 64 bit applications which can be faster than 32 bit ones but since we are still very reliant on 32 bit computing, it won't make any noticeable difference and the only advantage would be the extra ram.
