Multiply Your Apple or PC Memory for Less Than $60

Increasing the memory capacity of your Apple or PC can breathe new life into an old (or even new) machine – perfect if you’re still counting the cost of the holidays and simply want to enjoy using your computer again. Data Memory Systems, the Apple memory and PC memory specialists have a 4GB chip for under $60 – a price guaranteed to beat the January blues!

You’ll know it’s time to multiply the memory in your machine because programs will be slower to load, games won’t run as quickly and everyday tasks will seem to take an age. Just like in humans, memory is used to ‘think’ so the amount of Apple memory or PC memory your computer has available determines how quickly it can open and close programmes and perform operations. A slow machine can really take the joy out of even the simplest of tasks.

If you want to upgrade your machine and not spend a fortune, Data Memory Systems’ 4 GB DDR3-8500 SODIMM Apple memory and PC memory chip is now priced at just $55 and comes with free shipping.

The DDR3 denomination (or double data rate three) means the chip will perform at double the speed of a DDR2 chip – transferring data two times as quickly thanks to higher bus rates and higher peak rates. DDR3 memory chips are only compatible with other DDR3 chips. Speed is not the only thing the DDR3 has on its side; it also consumes 30% less power than its predecessor giving even greater efficiency in performance.

The DDR3 chip is certified by Data Memory Systems for complete peace of mind. The DMS certification means the memory is from a major brand and of commercial grade. There’s also a lifetime advance replacement guarantee and a 30 day money back guarantee if you’re not satisfied with your purchase. Tested by the Data Memory System’s own in-house lab, you can be assured of long term component reliability.

Get Organized This New Year with A New Hard Drive From Data Memory Systems

By the second week of January most New Year’s Resolutions have already been discarded. Enthusiasm for eating healthier, spending more time at the gym and learning a new skill often fades quickly as the desire to keep to rashly made ‘self improvement’ promises falters. But, there is one New Year’s Resolution that is easy to keep and that is a commitment to getting organized and keeping your Apple or PC in tip top condition.

If your desktop is one of many cluttered with files and folders, pictures and videos, it could be time to increase the capacity of your machine and invest in a bigger hard drive or handy exterior USB hard drive. Upgrading your storage capabilities in this way will allow you to clear away the clutter and store files in a designated area on your PC for quick and easy access. Having files and folders dotted around your system’s hard drive can really slow down the performance of your machine, meaning your disorganization can be more than inconvenient – it can mean you’re not getting the most from the PC or Apple Mac’s capability.

Rather than delete things rashly and regret it later, order an extra internal or external hard drive from PC memory and Apple memory specialists, Data Memory Systems. You can then dedicate that new storage space for all of those archives that have been cluttering up your machine for the last 12 months.

Getting to grips with new storage is straight forward, with external drives being particularly quick to set up and use. There’s also lots of helpful information on the Data Memory Systems web site, to ensure you choose the correct solution for your needs and your machine’s requirements.

When the new drive is up and running, simply create folders for all of the material cluttering up your desk top and hard drive and move it over to its new home. Anything that isn’t accessed at least once a month can be moved, freeing up room and allowing you to find important files that much quicker.

Although it’s not necessary to install a new PC memory or Apple memory chip as part of your organizational chores, adding extra memory means that your machine will perform at an optimal level so you’ll be able to work more efficiently.

The different types of computer memory

When it comes to computer memory there are several different types. The main type of computer memory is the physical memory which is called Random Access Memory (or RAM for short). RAM memory is found on all computers, and allows you to read and write data to this type of memory.

In addition to RAM memory, your computer will also have a Read Only Memory, (ROM for short) or in some cases this will be called the cache memory. Most, but not all operating systems and computers also have virtual memory. This allows your computer to look for any areas of the RAM which have not been recently used, and copies them onto the hard disk.
This frees up space on the RAM, which enables you to load up more programs and applications.

Your computer will also have a long term storage memory, which is the hard drive or on some machines the floppy disk drive will serve the same purpose.

The development of PC memory

Magnetic drum storage was first developed in 1930 and gradually evolved throughout the 1940’s. This was the predecessor to today’s hard disk drive. In 1959, the development of integrated circuit technology got underway, when transistors were first inserted into silicon chips. In 1970, a 1024-bit memory chip was designed, and today the memory chip density is still doubling.

The function of computer memory

RAM is made up of integrated circuits which are known as chips. Each individual circuit has millions of locations where information can be stored; these are called cells. The cells comprise of a transistor and a capacitor which unite together and work with the assistance of the memory controller circuitry in your PC or laptop.

Basic ROM contains the instructions which are vital for starting your computer. ROM memory is stored on chips which are found on the motherboard. It is not possible to change, erase or remove these chips.

When the RAM becomes full, the virtual memory comes into play. The computer moves any data and program instructions from RAM to the hard drive and assesses them using a paging file. Virtual memory aids the PC’s short term memory shortage. This is not the best option. Adding additional RAM is always better than having to use Virtual memory.

There are two different levels of cache which are available for Central Processing Units (CPU). Level one is considered to be the primary cache, and is a small amount of memory which is designed to support the CPU. It enables the quick and easy access to data that the CPU frequently uses.

Level two is the secondary cache and is located on a memory card. The exact amount of memory is dependant on the CPU in your computer. A circuit which is integrated on the motherboard controls the level two cache and lowers the amount of time the CPU needs to wait for data from the main memory.
