[quote=Albert;2110939][in most normal terms] 1 gigabyte=1024 megabytes, so 2 GB = 2048 MB
If your board has 2 slots for memory, and supports a max of 2 GB, it’s probably better to only get the 2x1GB sticks, instead of 1 stick of 2 GB. Chances are that it wouldn’t properly support the single 2 GB stick as easily.
Plus, on some boards, you will get better performance from the board with 2 matching sticks due to the memory actually running in dual channel mode [for DDR performance]. Running one stick by itself would always run in single channel mode, and wouldn’t be able to reap the benefits of DDR memory.[/quote]
Yeah thanks alot for the info. I bought 2 x 1GIGS Vdata DDR2. Just install them. Truth is I dont see the difference, Maybe its my proccesor that needs upgrading but thats for another topic thanks again. CDFREAKS is the best.!!
[quote=Kerry56;2110940]It would probably be best to check in the manual for your computer and see if that board will accept a 2gb stick of ram. Some may not. Look in the manual or check the website of your computer manufacturer.
One other way of checking this online is to go to Crucial and put in make and model number of your computer and see what is compatible. Or if this is a home-built computer, enter the motherboard model. They also have an online scanner that will look at your computer and give recommendations on what will work. http://www.crucial.com/
And to answer your original question, memory working in pairs is usually the way to go in modern systems.[/quote]
thanks for the input. I used the crucial scanner & it gave me all the info i need about my pc. very useful website
[quote=ripit;2110941]You don’t have to worry about the exact size. they are standard so if your motherboard will take 2GB of ddr2 ram, you can use 2GB of ram. Its a trade off on how many sticks. If you have two identical sticks, you can run them dual channel on most motherboards, which will give a small performance improvement. It would prevent you from upgrading further though, without completely replacing the memory. If you get one stick you can add another one later (but as it probably won’t be identical, you probably wont be able to run dual channel, even after upgrading to another stick). I think most people go for 2 sticks and dual channel. If you are running xp, 2 gigs is plenty (no need to upgrade further later). If its vista, a lot of people run more than 2 gig (might want to consider upgrading into it). I don’t run vista personally but some others seem to think 4 gig is needed for top performance.
Fyi, good point from Kerry56, make sure it would even support a 2GB stick.[/quote]
thanks alot for the input. Very useful info. CDFREAKS Deserves a medal!!!
