ECC RAM is an acronym which stands for Error Checking and Correction Random Access Memory. As the acronym signifies, ECC Memory is one of the types of RAM or Random Access Memory. With the utilization of ECC RAM, this allows the system to trace and correct single bit errors. The disadvantage, however, of this memory is that it cannot correct multiple bit errors, that is why ECC Memory is not normally recommended for personal computers used at home because personal computers used at home are shut down regularly, sometimes they are not even use for days. Moreover, most modern PCs do not sustain ECC at all if you will just criticized and look at the specifications of the PC. ECC Memories instead are best recommended and found in servers because servers are not shut down.

There are two types of Memory Errors that an ECC may check and correct. The Memory Errors are either hard or soft. Hard errors are caused by the defects in fabrication in the memory chip and once they start appearing they cannot be corrected. While Soft errors, on the other hand, are caused mainly by electrical disturbances. ECC detects and corrects errors depending on the kind of error that occurs.

Memory errors can crash a computer if they are not corrected immediately. If the error crashes the server, it crashes the entire network, unlike if what crashes is only a personal computer at home or what we called client, it does not automatically affect other computers even if it is connected to a network. This is why ECC memory is recommended for servers rather than for clients.

ECC Memory is also of two (2) types. It is either buffered or unbuffered, if your ECC is buffered, it can hold data temporarily for one whole clock cycle before it is transported. This, however, foregoes speed due to the extra clock cycle. On the other hand, if your ECC is unbuffered, the system is allowed directly to access every memory chip on the module. This, however, foregoes a little bit of its reliability despite its being faster that the registered or buffered ECC.

Most users rather choose non- ECC Memory or unbuffered ECC than ECC Memory or buffered ECC probably for the following reasons:

1. ECC Memory is costly than the non- ECC Memory;
2. The motherboard that supports ECC functionality in RAM is likewise costly; and probably
3. ECC Memory controllers need additional time to check and correct the error.

Here, it is up to you whether to choose ECC Memory or non-ECC Memory. If you are to use a server you may better utilize ECC Memory but if you are going to use a client and you are up for a maximum speed, better choose non-ECC Memory.

There are quite a few technologies that are used in common parlance in the computer world. A lot of these are based on the latest developments that take place in the computing arena and this is true on account of the rapid research and development that occurs incessantly. No matter which part of the world you are in you will be able to keep abreast of the many developments that occur every now and then. One of these refers to the growing popularity of what is known very popularly as Dual core technology which is making waves and has also gained a great deal of acceptability around the globe. It makes sense to get an idea of what this new and latest technology means and is all about.

Chip makers like Intel as well as AMD have brought out huge ads that tom-tom the appearance and launch of what is known as technology that is dual core in nature. There are commercials and advertisements which are being released to explain what this technology is all about and how it will help you as a user to do back up management with ease. With the dual tech it is possible to have two cores inside the same processor. This is very important and useful as it means that you can use the same computer for performing a couple of tasks all at the same time. This is why it is so useful for multitasking. Now a lot of people like to do a couple of things at the same time. For instance in making videos people have to shoot the movie, get the clips and the sequences together and also add in all the effects needed to be added. If you were using a single processor computer, you would have to do all of this sequentially. But if you used the Dual core technology, you could do the video editing and also add in graphics or animation all at the same time without any problems.

There is a great deal of convenience that you experience with laptops around. You can do all your computing on the go and be connected while traveling across the country and indeed around the globe. While it is impossible to lug the desktop computer around, with your laptop and with wi-fi internet connectivity having made a big splash, the whole world becomes your virtual office. You can send e-ails, complete and dispatch assignments, dash off memos and even video conference with your colleagues no matter where you roam around in the globe. It is no wonder that people are gushing over laptops and the great convenience that these bring to the fore.

There are quite a few people who are really not sure about how a laptop memory upgrade is done and a miniscule minority may not be aware of the utility of this. For one, computer software is constantly changing. Newer and upgraded versions of software and applications are being launched every now and then, which make huge demands on the RAM (random access memory) of your computer. As this is not optimal and could lead to a system crash, a memory enhancement may not only be advisable but also inevitable. After all, you would not want your computer to conk off or collapse and crash while you are in the midst of an important task or corporate presentation due to inadequate memory. When you want to add in extra features and more functionality by adding on newer software, you should be sure that your hardware and memory is also well able to keep pace with this.

You will need to do laptop memory upgrade if you are planning to scan an image or document that has high resolution. One of the obvious sign is, you will experience slower startup duration when you turn on the laptop.

First thing first, you should find out the exact amount of memory requirement for the applications that you are using. Knowing the current RAM capacity and the number of RAM slots available will help you to make a better decision choosing the right laptop memory upgrade to be done. You need to realize that it is unnecessary to install RAM more than what your laptop can cater to because that will only be a waste of money.

Buying the right RAM will help you to save money so you should look around for the shop that can offer you the best bargain for the money that you’re willing to spend. Most of the time, people will buy their RAM directly from online stores selling laptop memory to save themselves from the hassles to visit a store in another town to save more money.

When it comes to laptops, they represent a world of convenience as you are able to carry these around and also make sure that you complete your tasks on the go. While on the topic of laptops, you need to know that like in the case of desktops, the RAM or random access memory plays a very important role ion the functioning of the laptop. Laptop memory is so very important not only in terms of the hard disk memory space but also the RAM that helps in effective data retrieval and usage. There is no wonder then that around the globe, when people look at buying laptops and notebooks, they look at the RAM requirements that they have to effectively complete the tasks that are at hand.

There are a lot of people who do not pay any attention to RAM when they buy their laptops. They may be ignorant or perhaps plain negligent on this. But when the laptop works slowly or perhaps conks off in the middle of important tasks, they wonder as to what happened suddenly. They do not know but they my have opened up a number of tasks on the laptop all at the same time, leading to its crash or perhaps a slowdown. This is due to inadequate RAM leading to demands for a RAM upgrade that is essential.

When it comes to Laptop memory, in most cases, mini laptops come with 512 MB RAM. This was the case earlier, but nowadays as programs and applications become more advanced and memory hungry, 1 GB Ram has become quite the norm such that people can cope with the demands of the latest software and gaming that has become so very popular in this day and age. There are quite a few laptop manufacturers that also recognize the need for higher RAM which is why there are some which offer upgrade worthy versions where you can increase the RAM to about 2 GB also. This is not only possible but also becoming increasingly common in the world of mini laptops.

Getting adequate Laptop memory is very important to effectively run all the many applications that need to be run. People do see the difference clearly when they upgrade from a 512 MB to a 1GB or perhaps 2GB RAM. Applications run much faster and the computer does not shut off suddenly. You may not know but when you are in the midst of important tasks, this is quite essential.

Upgrading the mini laptop is not at all tough as you can remove the bottom of the laptop and insert the new RAM after pulling the current supply off. RAM costs have also moved southwards such that it is much more affordable to get an upgrade done.

Every computer needs memory to work properly. The integral computer memory is called the Random Access Memory or also known as RAM for short. It is named this due to the fact that the data stored in it may be accessed in any or random sequence. It is generated on tiny circuit boards in the form of sticks that are usually called as sticks of memory. Information is saved in the memory as it waits to be processed by the central processing unit or popularly known as the CPU. It is critical to have the correct type and speed of memory to guarantee the optimal operation of your computer system.

Currently, the basic type of memory implemented in your desktop computer system is Synchronous Dynamic RAM (SDRAM). Although, since the past few years, Double Data Rate SDRAM (DDR SDRAM or simply DDR) has been the standard for a majority of systems, with previous memory now being called to as Single Data Rate (SDR SDRAM). Sometimes, certain systems use Rambus Dynamic RAM (RDRAM) or DDR2 RAM that are a bit different and are not within the scope of this article.

SDRAM is not similar to other types of asynchronous memory because it waits for each computing cycle or clock before responding to inputs. These clocks occur very quickly in computers (millions of times per second) but still the computer bus eventually bound the speed of the memory. This is the wiring on the motherboard or mainboard in the system, which connects the entire component together. The memory and processor can both manage high-elevated clock speeds, although if the speed of the system bus is at a low level, they will be bounded by the lowest possible speed. It is crucial that they all work at comparable speeds to operate with efficiency. As an example, SDR SDRAM are available in PC66, PC100 and PC133; these numbers correlates to the clock speed of the RAM measured in megahertz (a million cycles per second): 55 MHz, 100MHz, and so on. In case the system bus speed rate is at 100 MHz and the memory is at 66 MHz, thus the memory is not working as fast as it may be and it is recommended to purchase a PC100 memory. Of course, if PC133 was bought for the system above, the additional 33 MHz would automatically be wasted because the system bus can only manage 100 MHz.

Double Data Rate (DDR) memory is quite similar to conventional SDRAM except it transfers data two times during each clock cycle. This increases the transfer rate of the memory by twice as much while the system bus remains the same. Thus a 100 MHz system bus that manages DDR memory can successfully utilize 200 MHz RAM. DDR are available in various speeds, each of them with two designations. Somewhere in the specifications or on the box, the memory will be labeled as DDR-xxx, where the xxx is substituted by the suitable clock speed of the memory like 200 in the example above. Also, it will list a PC-xxxx number, where xxxx signifies the bandwidth of the whole memory stick. This is not mainly essential to understand for beginners. The most usual are: DDR-200/PC-1600 that works at a clock speed of 100 MHz (effectively 200 MHz), DDR-266/PC-2100, which works at 133 MHz (effectively 266 MHz), DDR-333/PC-2700, working at 166 MHz (333 MHz) and DDR-400/PC-3200, which works at 200 MHz (400 MHz).

It is quite essential to know which type (SDR or DDR SDRAM) and speed of memory your system utilizes and to consistently buy this type when replacing or upgrading your memory. You can generally locate this information in technical manual or by contacting the manufacturer.
