There are hundreds of thousands of makes and models of memory...How do I choose the right memory for my computer?

The easiest way is to select a reputable memory seller who tests and guarantees compatibility with your model computer, who offers a lifetime warranty, and a no-cost return (no restocking charges) if it doesn't work. (see the CanadaRAM 7 point protection plan for how we meet and exceed these standards).

Why is this important, isn't memory a commodity anyway? What's the difference as long as it says PC2700?

There are some basic memory specifications across the industry. Take PC2700 for example, this describes a DDR memory module that runs at 333 MHz. Then add DIMM or SODIMM, which describe the physical packaging of the memory. But that is not nearly half of the information you need to know if the RAM will work in your machine or not. Some of the variables are the number of chips on the module, the density of the individual memory chips, the timing, the organization of the chips into banks, rows and columns, and the Serial Presence Detect settings. Your computer will work with only some of the many possible constructions of module.

So quite apart from RAM being a commodity, there are many variations that have to be accounted for.

Thats where we come in. We know memory, we have been supplying it for over 17 years. We have multiple cross-references, which we use to ensure you get the right memory for your machine.

Will my machine perform faster if I buy more expensive RAM?

In general, if two RAM modules are compatible with your machine, they will perform identically, regardless of the price difference. The trick is to ensure that the RAM you are considering is in fact 100% compatible.

The computer sets the speed that the RAM is run at, not the RAM module. So installing faster than specified RAM usually makes no difference, the computer will simply run it at its standard speed. So there's no real reason to purchase higher than specified RAM. (Keep in mind that purchasing slower than specified speed RAM may not work at all, or may force the machine to slow down, and this is not recommeded.) On occasion, we will supply you with faster than specified RAM on your order, if the price is the same, the faster RAM is in stock and the faster RAM is compatible.

The exception is overclocking and motherboards that are capable of automatic memory buss optimizing. In the case of overclocking, the computer owner is manually changing their machine by adjusting it to run at faster than normal buss speeds. This has some inherent risk of instability, crashing, overheating and component failure if not done correctly. When overclocking, buy RAM that is rated for the maximum speed you intend to clock the memory buss at.

Some PC motherboards have optimization technology built in to take advantage of faster RAM. This is not often an increase in clock speed, but a reduction in Latency. Latency is the length of time that a RAM chip must 'recharge' after a memory operation, before being ready to take another operation. The latency, or down time, represents wasted time for the computer's processor if it has to wait for the RAM. Low latency RAM is more expensive, but it can give a modest speed boost to the computer, IF the motherboard is built to take advantage of lower latency (faster turnaround) timing. All the RAM in the machine typically has to be capable of the lower latency. Macintosh computers and most laptop computers do not have this ability; it is mostly found in PC motherboards starting with the Intel 865 and 875 motherboards that use DDR RAM.

How much RAM do I need?

This depends a lot on the operating system you are using, and the type of work you do (the programs you run, the size of your data sets, and the number of programs that you need to have open at one time.)

When the mount of work you are doing exceeds the amount of available RAM, you machine is forced to swap working memory on and off the hard drive. This slows the performance of the computer. Ideally, you want to always have more available memory than the total of all the programs and files you have open.

For Windows XP and Macintosh OS X, the operating system itself doesn't reach full speed untill you have 512 Mb or more of memory. Add to that your programs' requirements, and you should be looking at between 1.0 and 1.5 Gb of RAM ideally. Graphics (Photoshop, desktop publishing and illustration), digital audio and digital video use very large data sets, so 2 Gb or more RAM is usual for these. Please email or call us to discuss your requirements.

Will installing RAM void my manufacturer's warranty?

No, virtually every computer manufacturer allows you to install your own RAM, with no impact on your warranty, as long as you choose compatible RAM, and don't do any damage to the machine while installing.

One note: If you are sending in a computer for warranty service, it is a good idea to de-install your upgraded RAM and/or hard drives. Increasingly, warranty service is done by swapping the machine for another, so you stand a good chance of getting a different machine back without your upgrades! Also an excellent reason to have a complete backup of your data before sending in a machine for service.

Shoud I buy the RAM from the computer manufacturer? Isn't it better to have factory RAM?

In a word, No. None of the computer manufacturers build their own RAM, they buy it from RAM manufacturers like Samsung, Hynix, Micron and Siemens just like we do. So there really is no such thing as 'factory' RAM. However there is agood reason not to order extra RAM with your new computer -- the computer manufacturers use RAM as a way to boost profit on the sale of the machine, and they charge anywhere from 150% to 300% more for the memory than we do. Also, when you buy RAM with the machine, you get only 1 or 3 years warranty, compared to our lifetime warranty. SO, buy your computer with the minimum amount of RAM, and then call us.
