Video editing computer RAM...
If you’re going to build a reliable video editing computer you must get to know a little something about the computer's...Random Access Memory...

Next to the computer's Central Processing Unit (CPU) RAM (also called Physical Memory ) is one of the most speed-critical elements on your video editing computer. In most cases, even with a fast CPU, a computer system without enough Physical Memory will be very sluggish.
There are a few ways that you can tell if a computer system has this problem... One good way is to look at the hard drive indicator light on your computer. On computer systems without enough RAM this light will be constantly blinking off and on... even if the user isn't doing much.
The more RAM (Physical Memory) a computer system has the less it has to access the hard drive to "Swap Out " data with the slower "Virtual Memory " located on the hard drive itself.
Having enough RAM is crucial to the speed and stability of your computer!
Modern computer processors (CPUs) can perform several billion operations per second creating and changing incredible amounts of data in a short period of time.
To perform at this level...
CPUs have to be able to quickly juggle the information they process and...
They also have to have someplace to store it until it is needed again for modification or reference.
That place is in the computer's "Physical Memory" or Random Access Memory (RAM).
RAM is actually a small electronic circuit board on which memory chips are placed. A memory chip is an integrated circuit (IC) made of millions of transistors and capacitors.
RAM is considered "random access" because the computer can access any memory cell directly... if it knows the row and column that intersect at that cell. Random Access Memory is also called "Short-Term Memory " because all of the information stored there is not saved after the computer is turned off.
Why the need for separate computer memory?
Of course... all modern computers also have hard drives which provide “tons of memory" and storage for data.
Even with the improved speed of today's hard drive technology...
Hard drives are still far too slow to keep up with all the needs of the processor (CPU).
The CPU needs and can operate on considerably more information per second than can possibly be transferred to and from the hard drive.
This is where the need for a fast, short-term memory solution comes in... A memory space that provides very fast access for the processor...So that data can be written and read as needed without slowing down the system appreciably.
This is the RAM. The computer's "Physical Memory". It is vital in a video editing computer that you have more than enough RAM!
Virtual Memory is a method of extending the amount of the available memory the CPU has access to on a computer.
When the "real " memory (RAM) is insufficient...
The computer's operating system will then use hard drive disk space as a place to store information until it is needed by the Physical Memory for processing by the CPU.
This is called "Virtual Memory".
Since the access time of RAM is in "nanoseconds" (very fast) and the access time of the hard disk is in "milliseconds" (much slower)... The system slows down considerably when it has to use the hard drive (virtual memory) for expanded memory processing.
Here is a short rundown on how your video editing computer RAM accesses and uses "Virtual Memory"…
This is how your computer handles the memory requirements of your programs and background services when there is not enough physical memory to do the job.
It is a fast operation but… not nearly as fast as just using the video editing computer RAM alone to store and retrieve information.
If You Want Speed and Performance When Video Editing… The Important Things to Remember about Video Editing Computer RAM Are…
If you want improved speed and performance the more video editing computer RAM… the better…!
The digital video editing process is one of the most demanding tasks for a modern video editing computer system to accomplish... Even more demanding on a computer than running the latest video games!
Make sure that you have more than enough video editing computer RAM...
So that your computer is fast and powerful enough to run your favorite video editing software program with ease...!
Have fun...! Dan
