Considerations to make when buying a computer CPU

There are many instances where you may feel obligated to buy a new computer processor. One may be that you are upgrading an old computer model, you want to increase the processing speed of your current computer or are basically just building a computer from scratch. Whatever your reason may be, finding a good computer Central Processing Unit(CPU) needs that you consider several factors. Below is an insight in this regard.

The CPU speed

The CPU has a clock speed that determines how fast programs in your computer can run. Traditionally CPU speed was measured in MegaHertz (MHZ), due to today’s technological advancements, the speed has changed and gone up to Gigahertz (GHZ). Generally, if you are not a computer nerd, you should at least know that the higher the speed the CPU you are buying has, the better it will be. Slow computer CPUs make the computer hang and may take ages to rum some programs while others may not be allowed to run at all.

The CPU model

Like many other products, you will be buying, it is always important to consider the manufacturing company. There are basically three manufacturers namely AMD, Cyrix and Intel. All have good and bad reviews on line. However as a wise buyer, you will always look at the percentage of dissatisfaction other customers have on the CPU you are buying. If the reviews are bad, then you will have to look at another model or another company.

The heat sink

The heat sink of the computer CPU, helps to allow the processor to stay cool. Cool processors generally work more efficiently than hot ones. Before going out to buy a processor or dismissing and assuming that your processor is bad, you should look at your heat s ink. If your heat sink is not working, or is not efficiently cooling the processor you have it could lead to errors, lock up and general slowness. Considering the heat sink first will help you solve the right problem.

The price

There are very few things that we buy without considering the price. It only necessary that you know that the higher the processing speed the processor will have the more expensive it will be. The prices will also depend on the company you buy the processor from; some may be more expensive than others. Therefore, if you want a processor that is more powerful and very fast, you will have to spend more.


It is also very crucial that you consider how compatible the processor you are buying is with the type of mother- board you have. There are models of the motherboard that are built to be compatible with most processors, however, some are specific. You will therefor need to read your previous processor’s name to know which to buy. If you are buying an LGA 775 CPU, you will need to have a mother- board with an LGA 775 motherboard. This is no like a hard drive that you can attach on the outside so it needs to be very specific.

Have A Look At Different Generations Of Computer Memory

Random Access Memory (RAM) is the processing memory of a computer or any other digital device like smartphone or a tablet. RAM allows the data stored in different parts of the computer memory in almost equal time at a very high speed for processing.
The integrated circuit RAM chips came into market in 1960’s and are evolving ever since. Here, is a review of all the RAM variants that came into market since introduction in 1960.

1. SIMM RAM Modules
The earliest RAM modules, Single Inline Memory Module are integrated chips with reading writing. These were available with two type of connector sizes 30 connectors and 72 connectors.

2. DIMM RAM Modules
DIMM or Dual Inline Memory module are 64 bit memory modules with chips on both sides. It has 168 pins with 84 pins on both sides.

A variant of DIMM, Small Outline DIMM has 144 pins for 64 bit and 77 pins for 32 bit memory. The RAM was designed for portable computing.

Dynamic RAM was one of the most popular memory types at the beginning of this millennium. However, technology evolved at a much faster rate since then.

The foundations of the present RAM architecture were drawn with DRAM Extended Data Out or sometimes called hyper Page. The frequency of these RAMs were around 33 and 66 MHz.

Synchronous DRAM were introduced in 1997. These RAMs have revolutionized the memory market, the RAM offered 150 MHz frequency with an access time of 10 ns.

The Direct Rambus DRAM were one of the biggest revolutions in the RAM technology. The RAM offered a frequency of 800 MHz and a bandwidth of 1.6 Gbps.

The Double Data Rate SD RAM doubled the speed of the RAM at the same frequency. The DDR RAM enabled the development of powerful operating systems like Windows 97 and XP. These powerful RAM’s supported giant operating systems with great data transfer rate and larger size.

The DDR2 RAM offered a never before transfer rate up to 6.4 Gbps at a frequency of 800 MHz. The RAM was one of the most popular RAM technology for almost a decade before its evolution into a better technology. These RAM’s work at an operational voltage of 1.8 volts and offer a FSB speed up to 1066 MHz. This offers a 240 pin DIMM un-buffered structure for desktops and a 214 pin Micro DIMM structure for smaller devices like Laptops.

The DDR3 RAM is the RAM chip which is currently being used by the industry. It works at 1.5 volts which makes it 30% more energy efficient than DDR2 and offers a great speed of 1600 MHz. The ram has two designs 240 pin DIMM design for desktops and 204 pin DDR3 SO-DIMM for compact devices like laptops and tablets. DDR3 also operates on cooler temperature, make it ideal for devices like tablets and laptops which remain in close contact with the users.

The DDR3 SDRAM is the best RAM available in the market till date. It offers great energy efficiency, better speed and does not heats up. These properties of the RAM opened tremendous opportunities for both computer as well as portable devices.
