WHY SHOULD I UPGRADE MY MEMORY?

Author: David C Smith
One of the very best upgrades you can make for your computer is to install more memory. Usually its more cost-effective than almost any other upgrade you might look at. And isnt that the purpose? To get the most bang for your upgrade buck.

Not only is installing more memory pretty cheap, most people can get it done for between $50-200. But, its also the most effective as well. It can improve your entire computing experience. From browsing the web, to doing multi-tasking, having more than one computer program running. Its especially important in families where the computer is used by different users. As that can be very memory intensive.

In todays computing world, you need at a very minimum 512MB of memory, and if youre going to be using Windows Vista, youd be better served with at least 1GB of memory. While youll find high-end systems with 2-4GB or more of memory.

However, knowing that you need memory is the easy part. Finding what memory you need for your specific computer is the hard part. It would be much simpler if it was like DVDs, every DVD runs in every DVD player. However, memory comes in different sizes, speed ratings and they are not all compatible with each other. Take note that laptop memory is generally a different size than what you can find in desktops. So, you wont find it interchangeable. The first place to look is in the users manual or any documentation you have with the computer, or on the manufacturers website.

What you must keep in mind is that sometimes its difficult to match the memory you need with the computer. You have to have the right size, and picking the right speed memory makes a difference as well. When you have a laptop the problem is especially apparent. Laptops are notorious for not having much space for memory, and being picky about the memory that will run in them. Usually the users manual or the website of the computer company can help you determine what type of memory you need to upgrade.

Typically you can find much of this in your users manual, or the manufacturers website. If not many of the memory manufacturers such as Kingston and Crucial have excellent websites that have the specs for most of the computers made in the last decade or two. Thats an excellent backup source of information.

Once youve done it once, youll quickly realize that upgrading your memory isnt that difficult and youll find your computing experience to be much more pleasurable. Getting a good memory upgrade can prolong the useful life of even ancient(4-5 year old) computers by allowing them to be functional for years longer. If you find your computer processes to be slowing down, and youre waiting around for what seems like hours for the most trivial tasks, exploring a memory upgrade might be an important step for you.

Just to be clear, we are talking about computer memory or RAM. The day is not quite here where we can upgrade our own memory with cybernetic chips. Or at least not that "they" are telling us.

Most people find that installing more memory in your computer can be quite cheap, and is usually pretty helpful. It allows you to do more tasks, more efficiently. For instance having more memory could help an excel spreadsheet to run a calculation faster. Opening up two Internet browsers wouldnt cause the whole computer to get slower. Even opening up a computer program to run it would be faster.

For the most part its best to start with at the very least 512MB, and with memory as cheap as it is these days, and with the future in mind, 1GB should be your goal. Especially if youre going to run Windows Vista or be using the computer for games or anything more than just simple web browsing and word processors. Its not uncommon today to see two to four gigabytes in your high-end computers.

The problem is not all computers are made equally. You cant just run down to your neighborhood computer store, and buy any old memory and expect that youre going to be able to get it to work with your computer. Laptops in particular are especially unforgiving of the memory that can be installed. There are different speed variations of memory, different sizes (laptops use different size than desktops). Generally you can consult with your manufacturer of your computer, or your documentation to find out what type of memory chip you need.

So, once you have the right size figured out, you have to go one step extra. You have to find out if you have the room to install more memory in your computer. Each computer has a limited amount of physical space to install the memory, and a limit to how much memory can be used. So, youll have to find out how much physical space is available, and what the impact will be if you have to switch smaller chips with bigger chips. For instance if your computer has two slots filled with 256MB chips for a total of 512MB, and you bought two 512MB chips. You would only have 1GB of memory, and the old 256MB chips will not be able to be used. Its a little complicated, but worth the trouble to figure out.

Typically you can find much of this in your users manual, or the manufacturers website. If not many of the memory manufacturers such as Kingston and Crucial have excellent websites that have the specs for most of the computers made in the last decade or two. Thats an excellent backup source of information.

Once youve done it once, youll quickly realize that upgrading your memory isnt that difficult and youll find your computing experience to be much more pleasurable. Getting a good memory upgrade can prolong the useful life of even ancient(4-5 year old) computers by allowing them to be functional for years longer. If you find your computer processes to be slowing down, and youre waiting around for what seems like hours for the most trivial tasks, exploring a memory upgrade might be an important step for you.

FORGETFUL? FIVE BASIC RULES FOR MEMORY

Forgetful? Five Basic Rules for Memory

All computers possess the ability to store information in its memory, also called Random Access Memory, or RAM. Some computers can hold small amounts of stored data in the memory and others have the ability to store massive amounts of information. Whether looking at memory for your next computer or trying to improve the memory on an existing computer, there are five basic rules for memory.

Knowing about RAM is the first rule for computer memory. Random access memory is a type of computer storage that allows files and information to be used. This process allows quick access to data that programs use. Most computer users have a version of Windows, such as Windows 95 or Windows XP as their operating system. Those who have Mac computers use another operating system. When looking at RAM for your computer, it is important to look at the size. Most computers users need a minimum of 128 MB. However, the larger the MB size, the better the computer will operate.

New computers with newer versions of Windows will need more RAM to run smoothly while an older version of Windows will require less RAM. Also, while a minimum amount of RAM will allow the system to operate, it may not perform at as well as it should. Therefore, a computer purchased today should contain at least 512MB to operate effeciently.

Another rule to remember when thinking about computer memory will be to become familiar with cache and how cache works. Cache, pronounced like "cash", is a special type of high-speed memory. The cache is a buffer between the processor and the main memory (or RAM). It will send data into the processes. This allows the computer to do the same functions over and over again. When the computer is called on to retrieve data, it will search the internal cache first. If the information is not found in the cache, it will search in the external cache chips next and then in the RAM last.

A cache holds all redundant information to save memory space and help the computer increase the speed. When the computer becomes slow, it is often recommended to clean the cache files and cookies that have been stored. By clearing space from these places, it allows the computer to process information faster. When it cannot locate the information in the cache, it will look in external cache chips and in the RAM. An example of how cache works is when a page on the Internet has been stored into the computer. This allows the user to go back to the last page or forward to the next.

Knowing what makes a computer work fast is another good rule for computer memory. Megahertz (MHz) is the speed measuring how fast a computer can think. Computers come in a wide variety of megahertz. This measurement of chip performance is expressed as millions of cycles per second. The higher MHz a computer has, the faster it will run. This directly affects how fast the computer can operate computers and commands. Some speeds on computers are measured in gigahertz (GHz). Gigahertz is measured in billions of cycles per second. One GHz is the same as 1000MHz. Computers with GHz are often used with programs that use multimedia applications. Typical processor speeds today include 2.4GHz, 2.8GHz, and 3.0GHz.

The last two rules of computer memory involve keeping the computer's memory clean and free to store more information and updating memory. Computers take a lot of memory to keep going. Storing too much information on a system is the number one way to slow the computer down. Having too much stored in the memory bogs the computer down and will often cause computers to crash as well. When a computer becomes slow, it is often necessary to clean the computer's memory by defragging the system or deleting unnecessary files and programs.

This article has been written with the intention of showing some illumination to the meaning of buying computer. This is so that those who don't know much about buying computers can learn more about it.

Computer users can find out how much memory their computers have by checking the system control panel in Windows. That information can be located in the About This Computer menu on a Mac. This can also tell the user how much RAM the computer can handle and what type of memory and the speed of the RAM. New memory for an older computer can be updated easily and inexpensively if more is needed.

Most computer technicians can install more memory into the computer with minimal cost. When looking to hire someone to install computer memory it is recommended to purchase RAM from a vendor that gives a good guarantee. And always remember to back up all files on a disk before having the memory upgraded.

LEARN ABOUT RANDOM ACCESS MEMORY OR RAM

Author: Tapan
Random access memory (commonly known as RAM or as simply Memory) is writeable as well as readable data storage used in computers and also in other electronic instruments. It is integrated circuits that allow the stored data to be quickly and randomly accessed at and without any physical movement of the storage medium or reading head in a constant trme. It connects to Motherboard via one of Socket Integration. Most types of RAM lose their data when the computer powers down. Computers use RAM to hold the program code and data during computation. RAM is also known as 'main memory' or primary storage. A smaller amount of static random-access memory is also integrated with the CPU, but this is usually referred to as "cache" memory, rather than RAM.

The word "random" refers to the fact that any piece of data can be accessed randomly, quickly, and in a constant time, regardless of its physical location and whether or not it is related to the previous piece of data. It is not serial access or sequential access memory like CD-ROM or megnatic tape etc.

There are various types of memoryTypes:

SDRAM (synchronous dynamic random access memory) which is a type of solid state computer memory.

DDR SDRAM double-data-rate synchronous dynamic random access memory is a class of memory. Effectively, it nearly doubles the transfer rate without increasing the frequency of the front side bus. Thus a 100 MHz DDR system has an effective clock rate of 200 MHz when compared to equivalent SDR SDRAM.

RDRAM or DRDRAM Direct Rambus DRAM or DRDRAM (sometimes just called Rambus DRAM or RDRAM) is a type of synchronous dynamic RAM, designed by the Rambus Corporation.

DDR2 SDRAM or double-data-rate two synchronous dynamic random access memory is a random access memory technology used for high speed storage of the working data of a computer or other digital electronic device. Its primary benefit is the ability to run its bus at twice the speed of the memory cells it contains, thus enabling faster bus speeds and higher peak throughputs than earlier technologies. This is achieved at the cost of higher latency.

DDR3 RAM double-data-rate three synchronous dynamic random access memory is the name of the new DDR memory standard that has been developed. The power consumption reduction is 40% as compared to current commercial DDR2 modules, due to DDR3's 90 nm fabrication technology using "Dual-gate" transistors to reduce leakage of current. DDR3's prefetch buffer width is 8 bit, whereas DDR2's is 4 bit, and DDR's is 2 bit. Theoretically, these modules could transfer data at the effective clockrate of 800-1600MHz to date, such bandwidth requirements have been mainly on the graphics market, where fast transfer of information between framebuffers is required. While the DDR3 specification will be available in mid-2007. Supposedly, Intel has preliminarily announced that they expect to be able to offer support for it in mid 2007 with a version of their upcoming Bearlake chipset. AMD's roadmap indicates their own adoption of DDR3 to come in 2008.

Major Manufacturers: Mushkin Samsung Micron Technology Corsair Memory Kingston Technology Rambus Technologies and Others.

The average computer, as of 2006, could hold up to 2 gigabytes of RAM, which is generally considered more than enough to sustain both intensive multi-tasking as well as heavy graphics applications.

Capacity measurement: The most common measurements of RAM capacity are 210 (1,024) or kilo bits, bytes or words of binary memory because 1,024 is close to 1,000. Similarly, mega and giga are used to represent 220 and 230, respectively. Thus a megabyte of RAM is almost always 1,048,576 bytes, not a million. In 1999, new prefixes, kibi, mebi and gibi, were introduced to unambiguously represent binary quantities, which is yet to catch up.

Several kinds of stable RAM are being development using the carbon nanotubes and the magnetic tunnel effect technologies. Data will preserve in these RAM while power shut down. These we see in the form of flash memory (pen drives). Capacities for these will now exceed 150 gigabytes with speeds far exceeding traditional RAM. This development will smudge the definition between traditional random access memory and disks, and will dramatically reducing the performance diffrence.

What is Computer Memory?
Memory is commonly confused with Hard Drive Space. The type of memory is actually Hard Drive Space which is stored on the computer Hard Disk Drive. The Hard drive is actually a physical drive which contains several parts and is generally larger than the amount of memory found in your computer.

Memory, which is commonly referred to as RAM (Random Access Memory), is a temporary (Volatile) storage area utilized by the CPU. Before a program can be run, the program is loaded into the memory which allows the CPU direct access to the program. Memory is a necessity for any computer and it is recommended that you have at least 64MB of memory for your IBM or Macintosh.

Computer Memory comes in ranges of different prices. You can find many discount from as little as Rs.280,00 to over Rs.160000.00. Price ranges for computer memory general depend on the manufacturers and the type of computer that you have. There are many quality manufacturers of computer memory like Kingston, Crucial Technology, Compaq, Sony, NEC and many more.

In many cases you can invest by upgrading your computer. Tips and Suggestion!

• Buy an Upgrade Kit. Upgrade kits are ideal if you don't want to bother with researching the motherboard that goes well with your CPU speed. Price wise also, it usually is better to buy a kit than buy the items separately.

• It's always a good time to add RAM to your computer. A memory upgrade is easy to install, is relatively inexpensive, and can improve the overall performance of your computer

• And for mission-critical applications using high-end servers, you might need as much as a 512MB upgrade to achieve maximum uptime and productivity or even a 1GB upgrade, depending upon your performance needs.

• If you are upgrading a laptop, in most cases you can only upgrade the memory, hard drive and modem. The rest you have to live with. If you can't live with it, then consider replacing it with either a new laptop or a used laptop.

• A memory upgrade is particularly helpful for users who work with large files, have more than one program open at one time, or use memory-intensive applications such as games or graphics and video editing software. Memory upgrades can dramatically speed up the overall performance of your home or business computer system.

Increase your RAM/Memory and speed up your computer (for Windows 9x, Me, NT, 2K, XP, 2003, and Longhorn)

TweakRAM is designed to clean your PC memory. It can Optimize RAM to make your computer run faster and crash less often. and Increase your system performance by cleaning the content of your RAM. and lets you know the CPU information, memory usage, processes, and applications running on your computer.

�This tool optimizes your RAM in adjustable, systematic periods and removes from RAM already closed programs which still occupy memory, thus making more free memory available to your system. While working with Windows XP (i have 512MB of RAM) i used to have only 100MB of free RAM before launch of this program and over 300MB after it. Yet again when some people may cry and write that it does nothing, I'm using it one or two times per day!"- wrote WinFuture.de about TweakRAM.

TweakRAM's main feature is memory defragmentation (it solves the problem of scattered program's code, so that your CPU doesn't have to waste time on code lookup). Many programs, including Windows, accumulate huge amount of libraries, but not all of them are necessary. TweakRAM finds such blocks and unloads them to swap. When some of this data becomes necessary it is loaded back to RAM again. Sometimes it happens that when program exits not the whole memory it allocated is released. Thus the program is not running any more, but some memory can't be used by other programs. TweakRAM finds such memory leaks and flushes them to swap file, thus increasing size of free RAM.

The program shows a detailed information about total size of physical RAM, free memory and the percentage of its usage by the system. The same information is given about swap file and the business of the CPU.

Since version 2.0 TweakRAM is supplied with its Application Startup Wizard which will help you configure optimal launch parameters of your applications. Now TweakRAM will automatically free needed size of RAM before/after program's launch.
