Knowing Your Computer: Types of Memory by Michael Russell
All computers require memory to operate. The main computer memory is Random Access Memory, or RAM for short. It is called this because the data contained in it can be accessed in any, or random, order. It is produced on small circuit boards in the form of sticks, which are often referred to as... If the system bus speed is rated at 100 MHz and the memory at 66 MHz, then the memory isn't operating as quickly as it could and PC100 memory should be purchased. ...

So, if you put in a memory chip of a higher speed, your computer will only run it at the maximum speed the system is capable of and buying a faster speed chip is just wasting your money. ... Aside from amount of memory, you also have to buy memory that matches the speed of your system.

Computer Memory Guide - What You Need to Know About Purchasing Computer Memory by Donny Duncan
Computer memory, also known as RAM (random access memory) is the place in the computer where the operating system stores information about applications and data in current use so that they can be quickly reached by the computer's processor. RAM is much faster to read from and write to than the... One very important note about computer memory, is you do not want to mix various speeds of memory, because the Motherboard will take the slowest speed and dummy all the rest of the fast memory to that slower speed.

Things You Can Do To Speed Up Your Computer by Jason Barrett

This is because new hard-drives run at faster speeds, So replacing the hard-drive will also help to speed up your...

I-RAM, M-RAM: Good Bye to Hard Drives? by Marcelo Reyes
A couple of weeks ago, one of my lab associates made a comment about the advantages of the I-RAM and its speed with respect to the hard drive. What is an I-RAM? I asked. Simple. They are a bank of DDR memories that are used as a hard drive. They are powered through a PCI port and use a SATA... Different to conventional Technologies of RAM memory chips, the data is not stored by electrical charges of current flow, but by means of magnetic storage elements. ... At the same time, while I was doing some research on I-RAMs I ran into some information about a new concept, the M-RAM (Magnetic...

How Do I Speed Up My Computer by Michael Baker
Speeding up a computer can be done in two different methods: software or hardware. When I say hardware, this would be a physical component, such as your hard drive or your memory.

DDR RAM by Ken Marlborough
The DDR SDRAM or double-data-rate synchronous dynamic random access memory, offers greater bandwidth than ordinary SDRAM. It is a type of memory-integrated circuit used in computers that transfers data on both the rising and falling edges of the clock signal. ... There are two sets of specifications: one for memory chips and the other for memory modules. ... Overclocking should be tried only by pros who know what they are doing, and only on high-quality memory. ... The DDR SDRAM package sizes and the standards of speed have been set by JEDEC (Joint Electron Device Engineering Council).

How To Know If You Need Computer Memory by Michael Russell

History of the Computer - Cache Memory Part 2 of 2 by Tony Stockill
(Times and speeds quoted are typical, but do not refer to any specific hardware, merely give an illustration of the principles involved.) Now we introduce a 'high speed' memory with a cycle time of, say 250 nanoseconds between the CPU and the core memory. ... This is high speed (and more expensive) memory compared to DRAM or Dynamic RAM, which is used for system memory. ... Expensive high speed memory is only required for a fraction of the capacity of the cheaper main memory. ... If the main memory is not core, but a slower chip memory, the gains are not as great, but still an improvement.

Why Should I Upgrade My Memory? by Alan Raimes
One of the very best upgrades you can make for your computer is to install more memory. Usually it's more cost-effective than almost any other upgrade you might look at. And isn't that the purpose?
