Thanks for the info, Thomas. I am still hoping I can prove this one way or another.

>First I must presume that a given PC has a sufficient amount of RAM to work properly, without having to go to the Hard Disk to store data. More RAM on a PC will in general give faster system operation. That we all know.

>I cannot prove one way or the other what the speed difference between two 256M modules versus one 512 M. However here are some thoughts on the subject. My background is electronics engineering and physics. I was familiar with the chip industry up until a few years ago having been associated with it on a professional level, from 1982.

>I can point you to a few Engineering books that will tell you that the amount of RAM and number of modules has an effect on system speed. There are other factors involved which include terms like “Propagation Delay”, and “Rise time”, that are more important than the amount of RAM you have on a motherboard. Also the type of RAM is a determinant of speed. In addition you must have a Chip Set and motherboard that are optimized.

>RAM speed is also related to the clock speed of the motherboard/CPU. One word of advice is to be sure that when using more than one RAM module with a Pentium motherboard, that the modules are the same speed – that is imperative.

>The above may be more than you wanted to know and here is a conclusion.

>The number of RAM chips on a module is inversely proportional to its speed. That is if you have more chips on a module it will be slower then if you had a fewer number. We are not talking about a significant difference unless you are an engineer or speed freak like I am!
