Gateway ALR 9200 Manual De Usuario

You must install DIMMs in the correct order and in entire banks. All 
DIMMs in the bank must be the same size and speed. DIMMs in other 
banks may differ in size. If you use slower DIMMs in another bank, all 
DIMMs operate at the slower speed (see Figure 4 on page 23).

The sequence in which you must fill the banks is:

1.

Memory bank A

2.

Memory bank B

3.

Memory bank C

4.

Memory bank D

System memory begins at address 0 and is continuous (flat addressing) up 
to the maximum amount of DRAM installed (exception: system memory is 
noncontiguous in the ranges defined as memory holes using configuration 
registers). The system supports both base (conventional) and extended 
memory.

•

Base memory is located at addresses 00000h to 9FFFFh (the first 
1 MB).

•

Extended memory begins at address 0100000h (1 MB) and 
extends to FFFFFFFFh (4 GB), which is the limit of supported 
addressable memory. The top of physical memory is a maximum 
of 4 GB (to FFFFFFFFh)

Memory holes can be configured in Setup or the SSU and are used by some 
legacy ISA boards. If you do not need to set up a memory hole for an ISA 
expansion board, leave the memory in a contiguous state for optimal 
performance.

Each memory bank includes 
two DIMM sockets in each 
row of connectors. When 
installing DIMMs, be careful 
to install the DIMMs in the 
correct sockets for the bank.
