The programs running on your computer and the data of variables using these programs must be stored in a location accessible to the microprocessor. This place is called memory and physically consists of a series of communications with the microprocessor chips through the bus address and data bus.

In the RAM data is stored and can be modified and read constantly. This information is erased when you turn off the computer because they need to be fed constantly.

Sometimes we have problems trying to install a new DIMM or SIMM memory in your PC and present failures such as error detection module correctly putting it still does not increase our amount of RAM.

To avoid these problems, we give the following tips that surely will be helpful, especially taken into consideration before installing your new memory.

Make sure you are not mixing memory type PC-66, PC-100 and PC-133.The only way to check the BUS speed of each module is a module mounted in the PC and with the help of a diagnostic program you can check.

When you run the test preparation called Main Board Information. The program will provide a lot of information about your motherboard, among them the BUS speed of your RAM. Once you know it and point it shuts down the PC. Remove the memory module install the other and repeat the operation to check also the BUS speed. If speed does not coincide in both cases you know where the problem is. If the contrary proves to be the same in both modules, then spend the next point.
