Select the RAM

New RAM may be needed when an application locks up or the computer displays frequent error messages. To determine if the problem is the RAM, execute the RAM test in the BIOS. The speed of the new RAM must be supported by the chipset.

• •Unbuffered memory – This is regular memory for computers. The computer reads data directly from the memory banks making it faster than buffered memory.

  •Buffered memory – Specialized memory for servers and high-end workstations that use a large amount of RAM. These have a control chip built into the module that assists the memory controller in managing large quantities of RAM.
