Guide to PC Memory

To increase PC performance, increase RAM purchasing despite the least costly, yet most effective route. Although the solution seems simple, because of the dizzying array of today's memory card, the actual decision-making process can be problematic for everyone, only for tech-savvy individuals. A wide range of different RAM types can be purchased today, SDRAM, EDO, RDRAM and DRAM to name but a few. Knowing how to determine which RAM types are compatible with the current PC settings and what RAM selection is the most powerful is crucial to make the right decision.

The purpose of this guide is to provide the reader with a general understanding of what RAMs are, what kind of RAMs exist and how to decide if RAM is the best choice.

What is RAM?

The acronym for RAM is Random Access Memory. RAM is the place where data is stored on a computer to access data from your PC processor or processor. RAM should be considered as temporary memory on the computer, so that RAM stores data storage, it should receive a continuous electrical pulse. Any data that exists exclusively within PC-RAM will be deleted if the computer is turned off or lost power.

The PC uses a number of common technologies to store data internally at a more permanent level than RAM. These types of media include ROM read-only memory, hard disks, which store magnetic media permanently – or depending on their use – in semi-permanent form, CDRWs, DVDRWs, floppy disks and tapes. All of these storage methods are considered to be more reliable than RAM storage, although none of them offer RAM access speeds.

RAM stores data that are essential for immediate PC operation and makes it extremely fast and reliable. RAM allows the computer to work at a speed that is unavailable when replacing more durable data storage media. Think of RAM as a fast track on a expressway. RAM allows the most important data of the function or application to access the processor as fast as possible. RAM exists as a "fast track" for which PCs need immediate attention. So the faster you access your PC, the faster bits are available for your PC functions and applications to access your computer's CPU, the faster your computer runs.

RAM types

SDRAM, DDR-SDRAM and RAMBUS are the three most important types of RAM or PC memory used to date.

Modern RAM

Before the SDRAM is introduced, the PC memory is operated asynchronously from PC Clock Speed. This asynchronous operation would in itself bring bottlenecks within the PC and slow down overall performance. The clock is the speed with which the microprocessor performs the instructions; Each computer has an internal clock that controls the processing speed and synchronizes individual components of the PC. As soon as it is justified, the faster the PC clock speed, the faster it can process data from PCs. Before RAM is synchronized to run at the same speed as other computer components, the PC CPU would be forced to delay if RAM is available to accept the data. In theory, as long as the SDRAM was operating at the same speed as the system clock, it would be systematically and consistently available to the system – thus eliminating the data bottlenecks. By linking RAM and power to system clock, memory manufacturers were forced to increase memory performance to match PC clock speeds.


SDRAM – Synchronous Dynamic Accidental Memory Industries are looking for better RAM and PC performance .

SDRAM is available at 66, 100 and 133 MHz, PC66, PC100 and PC133. 66MHz RAM can theoretically run 66.6 million cycles per second and be compatible with a 66 MHz clock speed. Memory is generally considered backward compatible, so a computer with a 100 MHz clock can accept a memory module that is 100 MHz clock. The disadvantage is that the memory only works at 100 MHz.

SDRAM is no longer a choice for modern PCs, but due to the number of PCs using SDRAM, it is certain that memory manufacturers will continue to use this memory at some point. SDRAM has long been on the market and as such is widely available, even as a used product. This availability option offers the buyer the opportunity to save a large amount of money on the purchase but sacrifices a low minimum for reliability, as RAM does not have any moving parts and is generally durable and durable.


DDR and DDR2 – Double-Rate SDRAM – Result of PC Industries' search for better RAM and PC performance. DDR memory has been available since the 1990s and is a great advance in RAM performance. Essentially, DDR RAM improves performance by transferring the data twice to the processor clock instead of the SDRAM. Theoretically, a RAM module that updates the processor twice a day, twice the performance offered by SDRAM. In reality, DDR does not actually deliver SDRAM twice, but this improvement over previous standards.

Available DDR and DDR2 memory types include PC1600 – 200MHz, PC2200 – 533MHz, PC4200 – 533MHz, PC4200 – 533MHz, PC3500 – 400MHz, PC3500 – The first number is the maximum memory bandwidth, Module per second. The second number is MHz, the hour that the module is compatible with. Like SDRAM, the memory is backwards compatible with a PC2100 chip at 266MHz clock speed, along with a 266MHz and 200MHz clock speed computer.

DDR and DDR2 memory are standard PC industry standards and will continue to be manufactured for a while. Like SDRAM, DDR and DDR2 types have been in the market for some time and are being used or refurbished. Both the used and refurbished DDR memory can offer significant savings when purchasing, while providing a similar level of reliability for the new product.


RAMBUS RDRAM was developed by RAMBUS Corporation and is a patented version of RAM as it is only manufactured by RAMBUS. RAMBUS is a powerful version of RAM, which is typically found in high-end business class computers. Today, very few manufacturers use the RAMBUS standard because the DDR and DDR2 memory are similar and in some cases provide better performance. The RAMBUS memory is located between PC800, PC1066 and PC1200. Generally available RAMBUS PC800- () a () contains a number that denotes chip speed in nano-seconds, i.e. PC800-45.

Memory and Performance:

Adding more memory does not provide faster performance, so insufficient memory guarantees slowdown. There are lots of memory installed on your computer to ensure that your computer is running at peak speeds and efficiency. Adding memory almost always results in performance gains, especially when running multiple applications or multiple applications at one time. It's important to note that if you double your current installed memory, you will not see a triple boost in performance. You will almost always see some gain in performance, but you can go a long way in eliminating slow downs.

It's always my argument and good thumb that you never get too much memory. Thanks to memory configuration, it guarantees the peak performance of your computer.

How to choose memory:

Memory selection depends on several factors. First, the compatibility test. Whether you're building a new computer or simply adding memory to an existing system, it's crucial that the memory you buy is compatible with the motherboard. Most motherboards accept a special memory module, SDRAM, DDR, DDR2, or RAMBUS. To determine which type of memory your computer accepts or consult with the motherboard owner, Manual or, if not available, you will check the motherboard based on the brand and model number, enabling online access and defining the type of compatible memory .

Generally, a motherboard that accepts SDRAM accepts memory modules that have a higher nominal speed in MHz than Table manufacturer. For example, if the current motherboard accepts 66 MHz clock speed and PC66 SDRAM, you can install PC100 or PC133 RAM chips. The card uses the memory at maximum speed, so the PC133 SDRAM module only operates at 66 MHz. It is important to determine what RAM speeds – in MHz – the card is compatible with the purchase.

Owners of manual or online documentation should also consult to find out that the board will support maximum memory and physically check the board to determine the number of available memory locations. Usually you want to use the largest and fastest RAM chips that will be supported on the board and load all available storage at an appropriate memory speed. For example, the board has three available slots, and currently uses a DDR PC2100 266MHz RAM module. You'll find that the card accepts DDR RAM to the PC2700 333MHz. If the memory PC2700 spends the remainder in memory, the memory is only the slowest RAM module, in this case it runs at 266 MHz. Used in:

Because of the sheer amount of memory produced over the last few years, there are lots of used memory. When you make the most of your money, you should note that buying used memory is a great way to save money while having similar reliability and performance compared to the new one. RAM has no moving parts to talk about, and as such, extremely durable and reliable.

Spend some time researching new and used memory modules. If you buy purchased or refurbished gadgets from vendors who offer a warranty, you may be making a big mistake by spending extra money on the new RAM.

Small research on your part will help you not only ensure that you get maximum performance from your computer, but also save money in the long run on the long run.
