Inside a desktop computer (PC) or laptop, memory or RAM (Random Access Memory) plays an important role in the performance and the performance of the computer. This time we will know a little more on what the memory/RAM (Random Access Memory) and know the types of RAM such as DDR, DDR2 and DDR3 SDRAM, as well as tips on upgrading RAM correctly.
RAM stands for Random Access Memory, which is a type of memory that is volatile (can be added, modified and deleted). Conversely, a ROM (Read Only Memory) which is non - volatile or can not be added, changed or deleted.
The forms include a ROM chip EEPROM. Said to be volatile because after the computer is restarted, for example, data stored in RAM is lost. Meanwhile, the data in ROM (non - volatile) still remain. On a computer, RAM (Random Access Memory) or Memory is a device in which to save data accessed by the processor/CPU (Central Processing Unit). Existing data in RAM can be accessed randomly with the same speed, so called Random (random). Data stored in RAM is temporary, as it will only exist if there is no electricity or when the computer is on and will be lost if the computer is off.
Basically the bigger the RAM, the faster a process carried out, because the CPU/processor can process more data. Existing data in memory Laptop/Computer can be accessed much faster than those in the hard drive, only for DDR2 SDRAM can be 40 to 100 times faster than the access to the hard drive, and for the type of DDR3 can be 100 to 300 times faster than the access to the hard drive (as an illustration, access SATA hard drive to date the highest transfer rate of about 80 -100 MB/s while USB 2.0 between 10MB/s and 20 MB/s).
Types of memory RAM (Random Access Memory)
Nowadays most computers already use DDR3 memory types (some types of DDR2). Prior to 2002, is still popular type of computer memory using Single Data Rate (SDR) SDRAM. But along with the development of technology, its use began to be replaced by DDR (Double Data Rate), starting from DDR1, DDR2 and now DDR3 which is widely circulated. DDR is theoretically capable of a transfer rate of 2X faster than SDRAM. Development of the RAM memory of the earlier and later versions generally have a higher data rate and lower power need. DDR2 is theoretically have 2x data rate with the same specifications than DDR1. DDR3 also has advantages compared to DDR2, such as higher performance in power/lesser power, higher bandwidth, latency which is superior.
Each type of RAM are not mutually compatible and designed with a different slot, so if we mistakenly put, for example, should have a computer/laptop using DDR1 memory types, we install DDR2 memory types will not automatically go into the slot.
RAM memory types also vary in terms of the workings and design (module). Laptop/notebook using the module type SODIMM (Small Outline Dual Inline Memory Module) (Memory DDR - SDRAM, DDR2 - SDRAM or DDR3 - SDRAM). So, if you want to buy RAM memory for notebook, select the type of species SODIMM DDR - SDRAM, DDR2 - SDRAM or DDR3 - SDRAM, depending on which is used in your laptop. So do not buy the wrong RAM memory for a personal computer (PC) to be installed on the laptop, because the form of RAM memory for laptop design is smaller than the memory of personal computers (PC).
Consideration Upgrade Memory (RAM)
Upgrading memory is usually done because of the need to increase the performance of your computer/laptop and because of the requirements that must be met in order to install certain software. For example when you are using heavy applications such as video processing/audio/graphics/games require minimum memory size for software operation can run more smoothly and normally.
Addition Memory will typically improve the performance of computer/laptop significantly, but we need to know the memory usage by the number that is too large (exceeds the performance of the computer) usually does not have much effect, for example if it is above 4 GB RAM, usually not much visible improvement. For example, Windows 7 usually requires at least 2 GB of memory, so for the less, should be upgraded in order to get good performance, but when we upgraded the memory in this case exceeds 4 GB feels it would be too big, choose a large memory in accordance with the requirements of your computer.
Steps RAM Memory Upgrade
To add to (upgrade) RAM is relatively easy, installed RAM memory location is very accessible/reachable. We just need a Phillips screwdriver only. We just know the type of RAM used and check if there are still empty slots for installing RAM or can use software like Speccy to find an empty slot and the type of memory used. Noteworthy is the similarity of RAM, because it would not fit with DDR1 DDR2, DDR2 and DDR3 are not compatible with. Required the same type when going to upgrade the RAM.
For Memory notebook/laptop with a slightly different size RAM desktop computer (PC), laptop RAM size is only half the RAM PC. When buying a computer store can mention the SO - DIMM (small outline dual in- line memory module).
DIMM is a kind of slots for Memory. Keep in mind that the type of RAM to have a variety, such as DDR3 - 6400, DDR3 - 8500, DDR3 - 10600, and the other (the higher, the transfer rate is also greater). Though for a different type was compatible, but the RAM will run at a lower type. For example, 2 GB DDR3 - 10600 in join with 2GB of DDR3 - 8500, will increase the amount of RAM to 4 GB, but will adjust the lowest performance (DDR3 - 8500).
Maximum amount of RAM depends on the motherboard and operating system used. For 32 - bit operating systems usually do not support over 4GB of RAM, while for 64 - bit systems, can theoretically support up to 192 GB of RAM (Windows 7 Ultimate). Additionally sometimes also limited by the maximum number of motherboard.
Before installing the new RAM memory, computer/laptop to be completely turned off (shutdown), not in STANDBY or HIBERNATE mode. When done in this fashion, can damage the memory. For that, use the menu " START | Turn Off Computer | Turn Off ", unplug the laptop battery voltage source or at the time of installation.
