DDR Memory & Motherboard Confusion
gman Oct-04-01 01:35 PM
I am currently researching components to purchase and build a personal computer. I definitely want to go with DDR and have noticed that most boards have between 2-4 DIMM slots. My problem is this: How do I achieve 3GB of memory in 3 slots if DDR only comes in 256mb?

You obviously cannot do it until 1 GByte DDR memory becomes available. I would think that 1.5 GBytes of memory would be more than enough for just about any PC. I have 256 Mbytes in my computer and that is probably enough for 99.9% of the PC users out there. In fact, you will see very little improvement in the performance of the average computer beyond 128 Mbytes. Larry

Saw this auction while looking around on ebay, this board supports dual athlon's and up to 3gig of DDR ram.

Larry,

Thanks for the headup.....I suspected this to be the case as far as availability, but I did not know about the performance above 128mb....Thanks for saving me the bucks

One way to tell if you really need more memory is to watch your hard disk LED. Open the number of Windows/applications you normally have open on your computer on a busy day, load documents, etc., and let things settle out. Start switching between Windows. If you see a lot of disk activity, Windows is moving stuff back and forth to the swap file on the hard disk drive because there is not enough memory to keep everything in memory. In effect, it is using the swap file to expand the actual memory in what is known as a virtual memory system. To get a good feel for what I am trying to describe here, reduce your memory, if you can, to 64 or 32 Mbytes and compare (or find another computer with less memory). You should see a lot of activity with 32 Mbytes, moderate activity with 64 Mbytes, maybe some activity with 128 Mbytes, and practically none with 256 Mbytes or more. Larry
