Memory Address Ranges - HP Model 715/100XC - Workstation Handbook

Determining the Faulty SIMM Pair
The address given by the System Responder Address is given as if the memory is
contiguous, even though empty slots are permitted. Memory boards are installed in
pairs of the same memory capacity. The operating system starts mapping memory at
Pair 3, if it exists. In other words, it maps starting with the highest numbered pair
through to the Pair 0. To determine the faulty pair of SIMMs, perform the following
steps.
1.
Using Table 4–8, determine the HEX value address range for each SIMM pair
in the system.
