RAM or Random Access Memory is critical to gaming laptops. Mainly because the more RAM you have on your laptop or computer, the higher the performance level you can achieve. Higher RAM will increase your enjoyment and let you play even the most challenging 3D games.


Besides the CPU (Central Processing Unit) RAM is probably the most vital element you will have in your laptop or computer. Just as you can't have enough money, so too you can't have enough RAM. The more the merrier. The more RAM you have, the faster your computer will perform.


Most serious gamers know their RAM. They know the difference between static and dynamic RAM. Many can even tell you how SIMM Landon Collins Hoodie , DIMM and SO-DIMM memory modules are different from each other. Plus, they would all know the importance of VRAM or VideoRAM to the operation of their gaming laptop. Most of all, they know their Graphics Cards or GPUs (Graphics Processing Units).


First, you should realize Sean Taylor Shirt , RAM is probably the best known form or type of computer memory. Second, RAM is very important in how well your computer can perform the tasks you call upon it to do. The more RAM you have, the more computer tasks and programs you can run at one time.


Nor should you make the mistake that only gamers are concerned about getting enough RAM; professionals who work with heavy graphics such as video editors, architects Preston Smith Shirt , layout artists, website designers... are also keenly aware of the importance of having enough RAM to get the job done. Keep in mind, computer technology is advancing at a blistering rate and is constantly changing. Overseeing all these industry standards and technology is JEDEC, which acts like a regulating body for the semiconductor industry. Hey Brandon Scherff Shirt , someone has to keep track of all these forms of RAM!


Basically, you have two kinds of RAM - Static RAM (SRAM) which is faster and more expensive than Dynamic RAM (DRAM). Just as their names suggest, Dynamic RAM is constantly refreshing and is slower and less expensive than Static RAM.


Static RAM is primarily used for cache such in your CPU's speed-sensitive cache.


What confuses most people is the whole range or types of Dynamic RAM, with more in development as we speak. Complicating the matter even further Montae Nicholson Shirt , is the development of RAM for laptops which need smaller and more compact memory modules.


Here are some types of RAM you may or may not have seen or heard of:


FPM DRAM -- which stands for "Fast Page Mode Dynamic Random Access Memory" and was the original form of DRAM. It has a maximum transfer rate of approximately 176 MBps to L2 cache; and if you're wondering what is level 2 cache, this is cache located outside the processor chip. Level 1 refers to internal cache in the processor.


EDO DRAM -- which stands for "Extended Data-out Dynamic Random Access Memory" and is around 5% faster than FPM DRAM. Transfer rate is at about 264 MBps to L2 cache.


SDRAM -- which stands for "Synchronous Dynamic Random Access Memory" is very common in today's computers. Transfer rate maxes out at around 528 MBps.


DDR SDRAM -- which stands for "Double Data Rate Synchronous Dynamic RAM" is similar to SDRAM but has higher bandwidth, allowing for greater speeds. Transfer rate to L2 cache is around 1,064 MBps.


DDR2 SDRAM -- which stands for "Double-data-rate Two Synchronous Dynamic RAM" Jonathan Allen Shirt , operates the external data bus twice as fast as DDR SDRAM.


DDR3 SDRAM -- which stands for "Double-data-rate Three Synchronous Dynamic RAM" and is an improvement over DDR2 SDRAM. DDR3 allows for chip capacities of 512 megabits up to 8 gigabytes, which gives you the maximum memory module size of a whopping 16 gigabytes.


Memory Modules


RAM modules are mounted on printed circuit boards to be used in personal computers. First, you had SIMMs (single in-line memory modules) which were gradually replaced by DIMMs (dual in-line memory modules). The main difference between them: SIMMs have a 32-bit data path and DIMMs have a 64-bit data path. Now for notebooks, you have SO-DIMMs (small outline dual in-line memory modules) which are smaller and more compact memory integrated circuits.


Of course Derrius Guice Shirt , like everything in life, there are radically different forms of RAM such as RDRAM which stands for "Rambus Dynamic Random Access Memory". This was designed by Rambus and has a high speed data bus nicknamed the Rambus channel. Likewise, you had Rambus in-line memory module (RIMM) and for laptops you had SO-RIMM.


Graphics Card


Next you must know there is something called VRAM or VideoRAM. This is a type of RAM is used for video adapters or 3-D accelerators. VRAM is located in the Graphics Card and is important for high resolution and color depth, both very essential for gamers. Since true multiport VRAM is expensive Da'Ron Payne Shirt , some Graphics Cards use SGRAM (synchronous graphics RAM) instead because it is cheaper. Other types of special high speed or multi-port memory include WRAM, DDR2, GDDR3 and GDDR4.


Your Graphics Card will be the heart of your gaming machine. Most gamers go for the top brands such as NVIDIA (GeForce) and ATI (Radeon) - the higher number series card usually means higher the performance. For example, at the time of writing Ryan Kerrigan Shirt , Nvidia has released the GeForce 9800 GX2, which is basically dual GeForce 8800 GT in one card. This will also give you DirectX 10 Graphics. Wait a couple of months and there will probably be something faster and more powerful on the market.
