Memory Configurations
The Intel 82865PE MCH component provides two features for enhancing memory
throughput:
•
Dual Channel memory interface. The board has two memory channels, each
with two DIMM sockets, as shown in Figure 3
•
Dynamic Addressing Mode. Dynamic mode minimises overhead by reducing
memory accesses
Table 4 summarises the characteristics of Dual and Single Channel configurations
with and without the use of Dynamic Mode.
Table 4:
Characteristics of Dual/Single Channel Configurations with/without Dynamic Mode
Throughput
Levels
Configurations
Characteristics
Dual Channel with Dynamic mode
All DIMMs matched
(Example Configurations are shown in Figure 4)
Dual Channel without Dynamic
mode
- DIMMs matched from Channel A to Channel B
- DIMMs not matched within channels
(Example configurations are shown in Figure 5)
Single Channel with Dynamic
Mode
Single DIMM or DIMMs matched with a channel
(Example configurations are shown in Figure 6)
Highest
Lowest
Single Channel without Dynamic
Mode
DIMMs not matched
(Example configurations are shown in Figure 7)
