The system boots up with a default setting of CPU FSB400 and DDR200. If the memory modules installed are DDR333 specification, please go into BIOS setup page and manually set the DDR frequency.
The recommended ratio between CPU FSB and DDR frequency is as following:
|
DDR200 memory
installed |
DDR266 memory
installed |
DDR333 memory
installed |
DDR400 memory
installed |
400 FSB CPU
installed |
CPU:DRAM = 1:1 |
CPU:DRAM = 3:4 |
CPU:DRAM = 3:4 |
CPU:DRAM = 3:4 |
533 FSB CPU
installed |
N/A |
CPU:DRAM = 1:1 |
CPU:DRAM = 1:1 |
CPU:DRAM = 3:4 |
In case you install FSB533 CPU and DDR333 memory onto BE7-E board, the CPU: DRAM = 3:4 will be a little tricky because this setting will cause memory module to work in DDR355 mode and hence the system may boot failure or be unstable. We recommend adopt CPU: DRAM = 1:1 for this configuration. |
