Ddr2 Memory: Your Reason To Upgrade
We all seek swifter and more efficient performance from our computers, investing in a variety of peripherals to assist in achieving greater heights of performance. Many PCs come with the latest in computer technology with speedy CPUs and large RAM. Since 2004, DDR2 Memory or Double Data Rate 2, has replaced DDR1 as the new generation in DDR technology.
DDR2 – What does it do?
Physically, DDR2 is different from DDR1. It cannot be used on PCs that do not come with DDR2 technology, as there are different numbers of pins: 240 pins in DDR2 as opposed to 180 in DDR1. In fact, in terms of speed, the DDR2 starts at 400mHz at the lowest level, which is the highest on DDR1. Therefore, upgrading to DDR2 will give you better performance on your computer. It can now function at faster speeds and adjust to higher data bandwidths, which makes for more rapid Internet browsing. This RAM also consumes less power, saving you valuable dollars on your energy bill if you’re a high computer user. With a thermal performance that’s enhanced, your PC will remain cool for a longer period of time compared with DDR1.
Points to note when buying DDR2
Be aware of certain factors when make your upgrade decision:
* Right RAM for your motherboard. Study your PC manufacturer’s guidelines on the recommended RAM for your particular machine before purchasing the DDR. Your new DDR must be an exact fit for your motherboard otherwise it will be money down the drain. The wrong DDR would cease vital functions of RAM and slow down your computer system.
* Increase both the RAM and speed. If you want a faster, more efficient computer, you have to upgrade both the RAM and the speed. There’s a specific speed for each computer. So get bigger DDR2 Memory!
* Don’t install memory yourself. You might find that your computer warranty becomes null and void if you do. Take your new memory chip to the Sales and Service Centre of a reputable PC manufacturer or a reliable computer accessories shop, and have the technicians there upgrade your machine.
Advantageous of DDR2
You will enjoy tremendous benefits from DDR2:
* Faster programs. Your computer applications will run at a faster rate, enabling you to complete your work in half the time. You can even effortlessly play high quality 3D computer games that rely on plenty of precise graphics and a fast PC for a stimulating experience.
* Enhanced program download. You won’t have to wait ages for your programs to download and you can switch easily between programs. You can also run more programs at once
* Increased computer speed. Your PC will be more efficient as it runs at a faster level.
Upgrading your PC to DDR2 Memory doesn’t have to be a convoluted matter. You could purchase the required component and proceed to any computer store to have it installed in your machine. Alternatively, you could take your laptop directly to the store, discuss your requirements with the technicians and follow their suggestions for trouble free computer usage.

20071006-08 – building Hades – 139-3920 – OCZ RAM (DDR2 800mHz PC6400 Dual Channel)

I don’t know a lot about RAM, but 800mHz PC6400 is waaay faster than my old 133mHz PC-133 ram. Apparently cutting edge RAM actually gets hot these days, so they have to include their own heatsinks on top. I’d never seen that before.
BACKSTORY: So, as mentioned before (in a 10-part series of blog posts), my trusty computer of 9 years, "Storm", died a nasty death. My secondary/kitchen computer "Hell" stepped up to bat and took Storm’s place, but I still needed a new computer for our somewhat newly-built upstairs space. So I built Hades, during which I wrote another 5 blog posts. These are the pictures I took while building it.

DDR1 RAM or DDR2 RAM – What is on my Computer?

DDR1 RAM or DDR2 RAM – What is on my Computer?
The very common and frequently asked and answered question from many of our clients to buy their DDR RAM memory modules is, How to find the exact type and specification of the RAM memory modules on their Desktop computer or Laptop. For all them the answer was the same and here is the full explanation to find the type of RAM (Whether DDR1 or DDR2) and other specifications like, the FSB(Front Side BUS) of the Motherboard, Clock speed of the memory module, FSB:DRAM frequency ratio, Total size of the memory and total number of channels you are using right now. These details will help to determine what memory module will better suit the Computer or Laptop for upgrading or replacement. Also, it is very easy to find all the details using a free software program called CPU-Z.
The CPU-Z software program is the free and you can get it from many places. Do a Google search for the term ” CPU-Z Download ” and you will get this program to save and install on your computer. Once installed as per instruction following the installation wizard, re-start the computer and run the program. This program once started will give all the above mentioned details on the “CPU” and “Memory” panels by switching the panels from the top lined tabs. Once you got all the details, you may contact your memory module vendor or the manufacturer’s technical representative to get the confirmation of the RAM memory module to use on your system. If you are going to buy a DDR RAM from a online shopping website, make sure there is a return policy if the memory module is not well suit with your computer.
Here the Effective Memory clock speed is the very common frequency written on the packing and on the memory module itself. The actual memory clock is different on DDR1, DDR2 and DDR3.
Effective Memory Clock For:
DDR1 RAM – 2xMemory Clock
DDR2 RAM – 4xMemory Clock
DDR3 RAM – 8xMemory Clock
An Example for memory clock speed of 100MHz on all three DDR RAM types. Let us calculate the effective memory clock speed for all the three types.
Effective Memory clock for DDR1/100MHz/DDR-200/PC-1600 = 2×100 = 200MHz
Effective Memory clock for DDR2/100MHz/DDR2-400/PC2-3200= 4×100 = 400MHz
Effective Memory clock for DDR3/100MHz/DDR3-800/PC3-6400 = 8×100 = 800MHz
Now using the above example, it is very easy to identify what kind of DDR RAM is on a Computer or Laptop. Plenty doubtful questions are still need to be cleared. But this is the basic to find which DDR RAM will suit best on your computer or laptop.
apart from all these better advice is to consult a computer specialist to know the best option on selecting the memory. It is not simply what type of RAM is on your computer. It is about to get the best performance. When upgrading a memory capacity, most of the time the real thing happens is a downgrading of the new memory module by using the new with the old. If the memory clock of the old memory is less than the new memory module, automatically the computer will detect and work to the speed of the old memory not the new one. You will get the real capacity of the memory. But the speed by which the data transfer happens will not change to the new one. The only solution is to remove the old DDR RAM an install only the new DDR RAM. As said earlier, there are many specific settings on the BIOS to set-up while upgrading or replacing a DDR RAM with a new higher capacity and higher speed one. It is highly advisable to consult a Computer hardware specialist before buying and installing a DDR RAM for this very purpose even you know how to install it by yourself.

Crucial 2GB Set(2×1GB) 200-Pin PC2 5300 667Mhz SODIMM DDR2 RAM
A small outline dual inline memory module SODIMM consists of a number of memory components usually black that are attached to a printed circuit board usually green. SODIMMs get their name because they are smaller and thinner than regular DIMMs. The gold pins on the bottom of the SODIMM provide a connection between the module and a socket on a larger printed circuit board. The pins on the front and back of a SODIMM are not connected. 200-pin SODIMMs are used to provide DDR and DDR2 SDRAM memory for notebook computers. 200-pin SODIMMs are available in PC2700 DDR SDRAM, PC3200 DDR SDRAM, DDR2 PC2-6400 SDRAM, DDR2 PC2-5300 SDRAM, DDR2 PC2-4200 SDRAM and DDR2 PC2-3200 SDRAM. To use DDR or DDR2 memory, your system motherboard must have 200-pin SODIMM slots and a DDR- or DDR2-enabled chipset. A DDR or DDR2 SODIMM will not fit into a standard SDRAM SODIMM socket. Information about which memory technology your system uses is included in the Crucial Memory Advisor tool. The number of black components on a 200-pin SODIMM can vary, but it always has 100 pins on the front and 100 pins on the back, for a total of 200. 200-pin SODIMMs are approximately 2.625 inches long and 1.25 inches high, though the heights can vary. Like 144-pin SODIMMs, 200-pin SODIMMs have one small notch within the row of pins; however, the notch on the 200-pin SODIMMs is closer to the left side of the module.FeatureProduct FeaturesEnergy managementInput voltage1.8V Technical detailsSource data-sheetICEcat.biz MemoryInternal memory2048MB Internal memory typeDDR2-SDRAM Form factorDIMM Bus clock rate667MHz ECCN CAS latency5
