This was posted by request of a member that just got this board. This guide is to be used as a template *only* - DO NOT just copy down these settings and try them as your own. Overclocking demands a great amount of responsibility, and I will not accept responsibility for ruining anyone's hardware because of just using the settings below and not doing the footwork yourself.

This is all backed up by a 24 hour burn-in using Orthos Stressprime at priority 10, and an 8 hour burn-in with Memtest86. Using Everest Ultimate Edition RAM Benchmarks, I've increased my read, write, copy and latency by DRAMATIC amounts!!! READ: 8110MB/s WRITE: 8246MB/s COPY: 6510MB/s LATENCY: 48.3ns (these are on par or better than DDR2 800 modules! - Check them yourself!!!) Oh, and yep...my HT is running at 1425MHz... I think I got a little lucky with my mobo, as it's been 24 hour Orthos Stressprime stable at a little higher than this! So, all in all, these settings have already helped loads of people with this board...I did alot of footwork here - countless hours of rebooting/resetting CMOS/taking notes/etc.
