Experts answer: test memory outside the first frequency is 533 or 667, you can use CPU - Z software testing, purchase of memory and the external frequency to the same old, if not buy the same external memory frequency, then enter the BIOS settings will work with memory-related settings Item in accordance with the specifications of low-speed memory settings. For example: using one of a memory (if it is DDR2533 and DDR2667 memory mixed with the best use of DDR2533 memory), the computer starts, enter the BIOS settings, the memory frequency and a slow reaction time, Stable operation of the old memory can prevail.
