Elixir DDR3 2GB

VIVAnews - IBMI (International Branding Marketing Inc) baru-baru ini memperkenalkan modul-modul Nanya Elixir DDR3 1133 SO-DIMM 2GB dengan penyerap panas terintegrasi. Produk memori anyar ini cocok ditujukan bagi para konsumen personal dan gamer yang ingin menghemat konsumsi daya.

Seri modul-modul SO-DIMM tanpa-buffer Nanya Elixir DDR3 telah diuji dalam platform motherboard dari semua pabrikan merek-merek ternama seperti Asus, Gigabyte, MSI, ECS, dan beberapa lainnya. Tak hanya itu, SO-DIMM Nanya seri ini juga menunjukan stabilitas yang tak biasa sehingga unggul dalam karakteristik kinerja, terlebih lagi untuk sistem operasi Windows 7, yang menjalankan game atau hanya sekedar menggunakan aplikasi sehari-hari.

"Seiring dengan turunnya harga modul-modul DDR3 dalam beberapa bulan terakhir, pengguna PC berkekuatan besar dan overclocker yang ingin meningkatkan sistem mereka ke tingkat ekstrim sekarang memiliki lebih banyak pilihan," papar IBMI, yang merupakan perwakilan penjualan eksklusif Nanya-Elixir DRAM di Indonesia, Vietnam, Filipina, dan Singapura, dalam keterangan persnya yang dikutip VIVAnews.

"Jika pengguna biasa mungkin tak terlalu membutuhkan disipasi panas khusus, namun para penggemar overclocking akan tertarik pada penyerap panas yang telah terpasang. Karena itu, seri SO-DIMM Elixir untuk notebook kini hadir dengan atau tanpa penyerap panas, tersedia dalam versi 1066, 1333 dan 1600 MHz," katanya.

Disiarkan VIVAnews sebelumnya, Elixir DDR3 SODIMM menggunakan chip DDR3 2Gbit 50nm dari Nanya, yang ditawarkan dengan kapasitas densitas hingga 4GB, dan sepenuhnya kompatibel dengan kebutuhan ekspansi notebook saat ini dan yang akan datang.

Di Indonesia, IBMI berafiliasi dengan grup Kingmax, sebuah penyedia memori terkenal yang menawarkan solusi-solusi memori dengan cakupan luas. IBMI mengkhususkan diri pada manajemen merek, dan pemasaran channel, bertanggung-jawab untuk merek Elixir di Indonesia.

What is DDR SDRAM?

Double data rate synchronous dynamic random access memory, or DDR SDRAM, is computer memory. The previous version is single data rate or SDRAM. DDR SDRAM was built on the technology of the prior version, but operates at almost twice the bandwidth or processing speed.

This is possible because the data is transferred using the double pumping technique. In this technique, the data is transferred when the clock increases and decreases. An additional benefit of this process is that no changes or adjustments are required to the clock frequency.

DDR memory transfers the data in 64-bit pieces. The actual transfer rate is calculated by multiplying the memory clock rate times two, as it is a dual unit. This value is then multiplied by 64, which is the number of bits that were transferred. The total value is divided by eight, which is a unit conversion for bits per byte. The final value is provided in megabytes per second or MB/s.

There are set manufacturing standard data rates for memory, which are set by the Joint Electron Device Engineering Council (JEDEC). This standard is divided into memory chips and memory modules. The standard naming convention is also divided into two categories: industry and consumer. The industry name is DDR, followed by the number of data transfers per second. For example, a DDR – 200 component provide a data transfer rate of 200 bits per second.

The consumer naming convention is based on the peak transfer rate. The DDR – 200 has a peak transfer rate of 1,600. Therefore, this unit would be called PC – 1600 in the consumer marketplace. It is exactly the same as the DDR - 200 unit. Package sizes are also set by the JEDEC, in the interest of consistency between manufacturers.

A DDR SDRAM module has 184 pins for the dual inline memory modules (DIMMs) of the desktop computer. SD RAM has 168 pins and the DDR2 SDRAM, which is the next version of DDR SDRAM, has 240. It is easy to tell the DDR and SD models apart, simply look at the number of notches on the memory card. The DDR version has one and the SD version has two.

Laptop Memory

There are lots of people who always in a conscientious effort to upgrade memory in laptop to increase its effectiveness. In desktop systems, you are normally given three or four slots for memory modules but this scenario is not seen with laptops as they only come with two slots.

Normally, laptops don’t use SIMM and DIMM memory which is used in case of non portable machines. When you will delve more into the details, you will find that following are the basic types of memory used in laptops;

• 72 pin SODimm

• 144 Pin SODimm

• SDRAM

• DDR SDRAM

Certainly the more memory in a laptop PC the better but there are other concerns regarding memory in laptops. Laptops are generally more restricted when it comes to terms of memory that can be installed into a system. More often access to that memory can also be a headache if you plan a future upgrade.

Most of the laptops are now using the DDR2 memory technology, but a number of new laptops use the DDR3 standard.

We generally find two ways through which the memory speeds can be designated. The first one is by the memory type and by finding its clock rating, like DDR2 400. Another r method is by documenting the type along with the bandwidth. In this instance the same DDR2 memory would be listed as PC2-3200 memory. Below is a listing in order of lowest to fastest memory types in both formats:

• DDR2 400 / PC2-3200

• DDR2 533 / PC2-4200

• DDR2 667 / PC2-5300 or PC2-5400

• DDR2 800 / PC2-6400

• DDR3 800 / PC3-6400

• DDR3 1066 / PC3-8500

• DDR3 1333 / PC3-10600

• DDR3 1600 / PC3-12800

In addition to the type of memory installed in the laptop, the speed of the memory can also make a difference in the performance. When it comes in terms of comparision, it is of outmost importance to check both of these pieces of information to evaluate how they may impact performance.

RAM

RAM (random access memory) is the place where the operating system, application programs, and data in use are stored so that they can be quickly access by the computer's processor. RAM is considered to be faster to read from and write to than the other available storage in a computer such as the hard disk, floppy disk, and CD-ROM. The data in RAM stays there as long as your computer is running or turned on. When you unplugged your computer off, RAM loses its data. When you turn your computer on next time, your operating system and other files are once again loaded into RAM, generally from your hard disk.

RAM is also known as "random access" because any storage location can be acheived directly. Originally, the term discriminates regular core memory from offline memory, commonly on magnetic tape in which an item of data could only be gained by starting from the beginning of the tape and finding an address sequentially. Perhaps it should be termed as "nonsequential memory" because RAM access is hardly random. RAM is organized and controlled in a way that permits data to be stored and retrieved directly to particular locations. You sholld note that other forms of storage such as the hard disk and CD-ROM are also accessed directly but the word random access is not applied to these types of storage devices.

Commonly RAM are of two types: DRAM (Dynamic Random Access Memory) and SRAM (Static Random Access Memory). The two types of RAM differ in the way they use to hold data, with DRAM being the more common type. When it comes to speed, SRAM is faster. DRAM needs to be refreshed more than SRAM. SRAM has the advantage that it does not need to be refreshed, what makes it faster than DRAM. DRAM technology supports access times nearly about 60 nanoseconds, SRAM can give access times as low as 10 nanoseconds. Despite SRAM being faster, it's not as commonly used as DRAM because it's too much expensive. Both types of RAM are volatile, which means that they lose their data or the contents when the cable is unplugged.
