Determining The Faulty Ram Card; Ram Stack Cards - HP 743 Service Handbook

Determining the Faulty RAM Card

If a memory failure is detected during memtest execution, the failing memory card is indi-
cated.
The following lists shows the location of the RAM stacks:
• RAM stack 1 is located behind the two PS/2 connectors on the board computer's
right side.
• RAM stack 2 is on the other side behind the LEDs and Audio port.
• The low-number slot position is next to the system board.
• Note that a maximum of three RAM cards are supported in RAM stack 1 and only
one RAM card is supported in RAM stack two.
Table 4-3 lists each RAM card location in each of the two RAM stacks.
