Getting a Memory Upgrade for Your Computer

When your computer begins to slow down, you might want to consider upgrading to a better memory. The random access memory (RAM) plays a major role in the overall performance of the system. It is responsible for temporarily storing files when the computer is still running so that you can quickly retrieve them. Your PC will experience some hitches when it gets damaged. Luckily, you can purchase a new RAM for increased efficiency in your computer.

What are the different types of RAM?

The most common types of RAMs found in computers include the following:

  • Static RAM (SRAM) - This is one of the two basic memory types (SRAM and DRAM). It operates with continuous power and does not need to be refreshed in order to read or write data. SRAMs consume less power than DRAM and are also faster when it comes to speed. The downside to this memory is lesser capacities.
  • Dynamic RAM (DRAM) - Unlike the static memory, DRAM requires change or action for operation. The "dynamic" part of the memory suggests that you will need to keep refreshing it for it to function. It has the advantage of higher capacities and is therefore ideal for video graphics and system memory.
  • Synchronous dynamic RAM (SDRAM) - This memory operates in sync with the CPU clock. It is a classification of DRAM but with an added benefit of synchronous operation. This means that the CPU can process overlapping instructions in parallel, what is usually referred to as pipelining.
  • Single data rate synchronous dynamic RAM (SDR SDRAM) - This is a branch of SDRAM that processes a single read and single write instruction per clock cycle.
  • Double data rate synchronous dynamic (DDR SDRAM) - The double data rate SDRAMs are an upgrade to the single data rate memory. They are capable of processing two read and two write instructions per clock cycle. In this class, you will find the DDR, DDR2, DDR3, and DDR4 SDRAMs.

What are DIMM and SODIMM in DDR3 SDRAM?

These are memory modules that are installed into the memory slots on the computer motherboard. They are almost identical in their performance but different in form factor.

  • DIMM - This is the dual in-line memory module. It is used in commercial desktops due to its form factor. The standard DIMM measures 133 mm and has a 240-pin connector. DDR3 DIMMs specify four chipset lines per memory.
  • SODIMM - This stands for small outline DIMMs. They are ideal for more compact PCs such as laptops, notebooks, and netbooks. They measure almost half the size of DIMM and have 204 pins. They also specify only two chipset lines per memory.

What factors should you consider when buying a RAM?

The capacity, speed, buffering, and latency are among the factors that affect the running of the computer:

  • Capacity - You will find anything from a 1 GB to a 32 GB DDR3. Lower memory capacities will work well if you only intend to use your PC for basic functions. Higher capacities, on the other hand, are ideal for video gaming and editing tasks.
  • Speed - The speed rating of the memory modules represent just how fast your computer can store and retrieve data from the local memory. The speed is measured in MHz or GHz. It can be expressed in the older PC2/PC3/PC4 or in the newer DDR terms. The speed rating comes after these terms. For instance, you can have a DDR3 RAM with a PC3-10600 rating. This can also be labeled as DDR3 1325 RAM. The first, 10600, is speed expressed in million bits per second while the second, 1325, is in million bytes per second. 1 byte is equal to 8 bits.
  • Latency - This is the time it takes the module to access single bits of data across rows and columns of the memory array. The lower the latency, the faster the operation of your computer in general.
  • Buffered or unbuffered memory - A buffered memory is more stable, reliable, and durable but less speedy when compared to the unbuffered one. Conversely, the unregistered memory is fast but less reliable and stable.
