| Q: | Why there is no DRAM Clock for 200MHz (DDR 400) option in BIOS when using AT7-MAX2 and KD7 series with 333MHz FSB CPUs? |
| A: | The Ratio (FSB: AGP: PCI) in BIOS will adjust the default to 5:2:1 when you use 333MHz FSB CPUs, and the DRAM Clock will not provide 200MHz(DDR400) as a selection at this moment. Also, the default setting will set to 166MHz because of the North Bridge Chipset limitation. Therefore, the option of a 200MHz DRAM Clock cannot be offered with a 333MHz FSB CPU chosen. The overall system performance will reach a peak at DDR 333 with a 333MHz CPU because synchronous mode is always the best choice for optimal performance. |
