The memory bar is not sorted in order to cause all memory to be found

This may be the case for several reasons:

1. This may be due to incorrect BIOS settings.

2. It may also be a question of the sequence of memory detections.

The following are the problem-solving methods:

1. Into the BIOS, the PC133 memory parameters set to the same speed as the PC100 memory, that is SDRAM.

2. Unplug the original PC100 memory after the boot, the smooth detection of PC133 memory, into the system is also very smooth. Because the brand is the same, so there is no problem with different memory-stripe conflicts.

3. Solve the memory detection sequence problem. This is because generally each memory has a SPD chip, memory detection, first read the first slot memory parameters, and then read the 2nd, 3rd. Swap the slots for 2 memory strips and place the PC133 memory strips in the 1th slot. After the boot system detects memory 128MB, if all is normal, on the line.
