You need to count how many ports you have filled and then find out how much of memory it is in total. Then check the BIOS summary for amount of memory recognized. It will give you answer to your question.
EDIT:
The above will only verify the presence of RAM, not whether or not it works correctly or reliably. (Obviously, if it's not being detected, there's a problem- but that could be the motherboard too!)
The most reliable method of testing memory is to use a benchmark program such as MemTest 86, WinRAM tester, or a stand-alone hardware based memory tester (which you can buy online). These tools will run repetative functions through the memory to verify it's function. Typically, MemTest 86 is the most reliable of the bunch, as most hardware testers only test as far as the BIOS does (just checks if the memory is responding). MemTest 86 and others will also test for reliability, bad memory clusters, timing errors, and more.
my 1998 doge ram van, all my gauges are not working
No, mine is working fine.
This depends on how it is not working.A general cure-all is to clear your RAM.
Check fuses and the headlight switch.
What do you mean the disadvantages of RAM its some thing your machine needs to run. When your machine starts it carries out something called a POST This will check your RAM CPU PWR monitor and keyboard are all connected and working on your machine with out these it will fail to boot.
If you want to know if your RAM is working properly you could look on you computer information to see if the amount of RAM that is in you computer matches up with what your computer tells you. For instance if you know that you've installed 8GB of RAM in your computer and when you turn it on the computer tells you that you have 8GB of Ram in your computer it should be working correctly. Also there are tests that will look at your RAM to make sure that it is running properly.
Random access memory (RAM) is the machine's working memory. All programs and data must be loaded into RAM in order for the central processing unit (CPU) to execute those programs.
RAM is memory the computer uses as working space. The computer doesn't have to search the entire Hard Drive to find what you're working on; the info is right there. To get out the RAM, you need to open up the case. The memory will be in sticks inside.
how do you tell if your fuel pump is working
A person can tell if a Ram is affected or not by running a virus scan on the computer.
The processor would be considered to be the brain of the computer. RAM is just part of the working memory of the computer.
