I can't seem to figure out how to set up my multiplier and frequency without screwing things up. I don't have any experience at all with fsb's and cpu frequencies. I've already updated the bios to ver1007 and checked jumpers but still no luck. When I first bought it. on the first boot it showed up as an XP 1800 and the ram running at 100mhz. I have a brand new stick of DDR400 and cant get the memory freq above 200. I'm not even sure how fast anything is supposed to run. Thanks in advance.

You will find all the info you need in the following threads :

1. Underclocked cpu on the A7N8X-D
2. Tips for builders
3. The ASUS A7N8X-X/A7N8X/A7N8X Deluxe Thread

In summary, you'll need to set your multiplier to 15x & FSB to 133. Run the Ram in Sync with the FSB ( 133mhz / PC2100 ) & you're good to go.

If you have other questions, make sure to use the Search Function in case it has allready been aksed & answered.
