How do l find out how much memory is installed in my system?

In Windows, click on the start button and open "Control Panel". Use classic view for Vista and 7. Then open "System". This will display basic information about the computer including the amount of RAM installed.

In MacOS, select "About This Mac" or "About This Computer" from the Apple menu in the upper left corner of your Desktop. This will provide information about your Mac's total memory (built-in memory plus DIMMs or SIMMs installed).

In Linux, open a terminal window and enter the following command: cat /proc/meminfo

This will show the total amount of RAM as well as other memory information.


Will additional memory speed up my computer?

Additional memory will not necessarily increase the performance of your computer. It will allow you to run more programs or processes at once or more memory intensive programs. There may be a performance increase if the original amount of memory installed was close to insufficient for the programs and processes you use the computer for.


Will kingston ValueRam (KVR) work in my brand name computer?

Kingston ValueRam (KVR) is Kingston's standard memory line designed with whitebox users in mind. Kingston ValueRam is engineered to meet industry standard specifications and is rigorously tested to ensure quality. However, it is not tested for compatibility in brand name machines such as Dell, HP, Gateway, Sony, etc., which may require specific memory timings and have limits to the DRAM densities used to support these systems. Nevertheless, if the memory meets the system specifications, you may install it to determine compatibility with your system. For help selecting memory, contact Kingston Sales on +1 800-835-6575 or use our Memory Search at
