In this video we are going to learn more about the different types of memory, speed and bandwidth and how they relate to each other, other features of memory you need to know about to make sure you get the correct memory for your system and we’ll show you another tool to help you identify the memory in your system.

Types of RAM and Identifying them

Lets begin by going over different types of memory and how they are identified in stores and online. In Lesson 1 we listed RAMBUS, DDR, DDR2 and DDR3 as the 4 different types of memory in use since 2000.

RAMBUS memory was in use from 2000 to 2004. It can be referred to as RDRAM and is usually listed as PC and then a number with no space in between. The numbers indicate the RDRAM’s effective speed in MHz and ranges from PC(600MHz) to PC(1200MHz).

DDR memory was in use from 2000 to 2004. It can be referred to as DDR-RAM and is usually either listed as DDR, space, and a number or PC, space, and a number. For example when listed as DDR 400 the number, 400 in this case, refers to the speed in MHz.

The same memory can be listed as PC, space, 3200. The 3200 refers to the bandwidth the memory has, measured in MB/s. Because some stores list only speed and some list only bandwidth its useful to know how to convert between the two ways of listing the same memory. We’ll show how in a few moments, after we cover DDR2 and DDR3 memory.

DDR2 memory has been in use since 2004. It can be referred to as DDR2-RAM and it is usually either listed as DDR2, space, and a number or PC2, space, and a number. For example when listed as DDR2 800 the number, 800 in this case, refers to the speed in MHz.

The same memory can be listed as PC2, space, 6400. The 6400 refers to the bandwidth the memory has measured in MB/s.

DDR3 has been in use since 2007. It can be referred to as DDR3-RAM and it is usually either listed as DDR3, space, and a number or PC3, space, and a number. For example when listed as DDR3 1066 the number, 1066 in this case, refers to the speed in MHz.

The same memory can be listed as PC3, space, 8500. The 8500 refers to the bandwidth the memory has measured in MB/s.

For DDR, DDR2 and DDR3 some shops list only speed and some list only bandwidth. You can convert from speed to bandwidth and back using a simple method. You either multiply or divide by 8. Take, for example, DDR3 800 memory. You can multiply 800 by 8 and you get 6400 or 6400MB/s which is the bandwidth of DDR3 800 memory. To convert from bandwidth to speed you divide by 8.

Other Features of Memory

Now that we know about the different kinds of memory and how speeds and bandwidths relate to one another, lets go over some other features of memory you need to know about. How many channels the memory is operating on is very important to know. It can be single, dual or triple channel. In single channel mode each memory stick runs at it’s own bandwidth. If you have for instance a PC2 6400 stick of memory it’s bandwidth is 6400MB/s. More bandwidth means better performance.

Dual Channel

In dual channel mode you can have 2 or 4 sticks of memory combining their bandwidth. So two sticks of PC2 6400 memory would become the first channel of memory and combine to make 12800MB/s of memory bandwidth. If you add another 2 sticks of PC2 6400 RAM to the system they would become the second channel of memory and combine to make another 12800MB/s of memory bandwidth.

Single channel is when your computer has 1 stick of memory or 2 sticks of memory just not in the correct memory slots. Dual channel can be activated if the computer has 2 or 4 sticks of memory. I say, can be activated, because the memory sticks have to be in certain slots on the computers motherboard. Which slots to use to activate dual channel mode depends on the motherboard. You have to look this up in the motherboard’s or computer’s manual or ask the computer maker to be sure.

Triple Channel

Triple channel is available on higher end Intel Core i7 systems that use the socket 1366 CPU interface and requires 3 or 6 sticks of memory. Using triple channel mode, triples the memory bandwidth. Like Dual channel, for the memory to run in triple channel mode the sticks of memory need to be installed into the correct memory slots on the motherboard.

Memory Timings

Memory Timings or CAS Latency, which is usually shown as CL= and a number is another measurement of speed. Its the time in nano seconds the memory waits between each operation. A lower number is better and more expensive. However the memory will run at the slowest CAS speed of any memory stick in the system. So if you have CL=9 memory and you add CL=7 memory memory it will run at CL=9 speeds. We’ll show you how to find what your memory’s CAS Latency is in a moment.

Computer hardware engineers research, design, develop, test, and oversee the installation of computer hardware. Computer hardware includes computer chips, circuit boards, systems, modems, keyboards, and printers. Computer hardware engineers are much like electronics engineers, but work only with computers. The rapid advances in computers are a result of their work. To keep up, these workers must stay up to date on what they know. A bachelor’s degree in engineering is needed for almost all entry-level engineering jobs. College grads with a degree in a science or mathematics may get some jobs.

Want to know how to start a computer repair business? All small businesses use computers and depend on them to work consistently, predictably and dependably. However, it is not cost effective for most small businesses to have their own in-house IT department. Still, they need someone like a computer repair business to help keep their IT assets up and running, so they can stay competitive in the marketplace.

No matter what your business experience or level of technological expertise, you can start your own computer repair business. Those that love computers, technology and working with people find that running their own business is incredibly fulfilling and can bring them substantial revenue. All it takes is following some logical, plotted steps and planning very carefully how to start a computer repair business.

The following 5 tips can help you figure out how to start a computer repair business.

1) Determine the Characteristics of Your Ideal Clients. Before you start your own computer repair business, you need to figure out who you want to serve. Know who your ideal clients are and which characteristics they share. How large are their businesses? Which major business problems do they face? As you start to fine-tune your idea of the ideal computer repair business client also think about whether you are serving a niche and what your specialty is. Are your clients all in a specific industry or do they naturally all use the same specific software or hardware? Having a niche and a specialty can really help you with marketing and sales. You will position yourself to offer solutions that no other technology professionals in your area are offering and thus be even more indispensable to your clients.

2) Know Your Strengths and Weaknesses. As you figure out how to start a computer repair business, you need to know your own strengths and weaknesses. You might have a very strong technical background but are not very business savvy. In order to succeed, you need to have a good balance of business, technical and also strong social skills, so you can best respond to the needs of your clients and build long-term relationships with them. Make sure you take the time to go outside your comfort zone and work on honing skills that come less readily to you than others.

3) Set Your Rates Right from the Beginning. When you run your own computer repair business, time is money. You cant afford to set your rates too low in the beginning. Not only will you have to work incredibly hard just to make ends meet, but you will also have a hard time raising rates substantially once youve already started your business, without losing clients and compromising relationships and your reputation. To make sure you start your business using competitive rates, identify your local competitors and research what they are charging their clients and how their services compare to yours.

4) Be Patient and Let Your Business Evolve Over Time. You cant expect to instantly get a full roster of clients and steady revenue for your business. When you are starting your computer repair business, you should expect it to take a while to get off the ground sometimes as much as 6 months or even a year. Why? A successful computer repair business is built on strong client relationships and relationships take time to evolve. You need to get prospects for your business that know, like and trust you in order for them to turn into steady, high-paying, long-term clients. Be patient and follow clear steps when qualifying clients and forging connections through marketing and networking events. And take each client carefully through the sales cycle. If you are diligent with your efforts, they will pay off in time.

5) Remember that Marketing is Key. When you are just figuring out how to start a computer repair business, youre going to be wearing a lot of different hats. You will probably have to do the marketing, sales, administrative and all other tasks by yourself in the beginning. Establishing a well-crafted, diversified marketing plan that incorporates a lot of different targeted activities is the only way to build your business and make sure your sales funnel is fed. So this way, you can attract new clients on a regular basis and still have time to manage other elements of your business.
