Why not do 9x289? Do that, and run a 133 divider (ddr266). Lower the LDT or whatever it's called to 3. You may need to bump the vcore to 1.425 to be Prime stable. Btw, do you know how to do dual Primes?

Also ive herd a fue peoples windows instlation going currupt what would cause this to happen?

If you're just trying to find the max of the cpu, you can run the ram lower than stock to take it out of the equation, then bump it back up (or oc it) to match the cpu. I would be very careful about going over 1.5v for a 165. People have done it, but you have to be sure and watch your temps closely.

1.55v is the max I'd do. What kind of RAM do you have, that would help.

Not trying the find my cpus max though.

This is the ram i have,

Okay, you'll have to loosen your timings to run that stuff over the spec'd speed.

Why? Running a divider doesn't necessarily hurt performance. In fact, running a divider and using tighter timings can result in INCREASED performance over running the RAM faster, but with looser timings.

Its pointless to try and just plug random numbers, INCLUDING other people's settings, into the BIOS. You should test the limits of:

RAM
HTT
CPU

...separately and then work them all together into stable setup.

This guide explains pretty much everything you need to do. RAM settings are crucial with nForce4 boards. If your RAM has a support forum (like OCZ or Corsair) then pay them a visit and ask for recommendations. Try the Abit forums as well; when I was setting up my non-SLI AN8 the search function at the Abit and OCZ boards were very helpful in finding a starting point for my RAM settings. Leaving the RAM settings to AUTO on the AN8 boards is not a good idea.

According to this guide you should run test 5 with at least 25 passes.

your chip may not be able to run above 2.4 with 1.45 volts. Try more voltage. If you arent comfortable with more voltage, then you may be at your cpus max at 1.45.

loosen your ram timings. Better yet loosen the timings and use the 100 ram divider and let me know what happens. Is your HTT Multiplier set at 3 or 4? Make sure its at 3. What kind of ram do you have.

Just do 3-3-3-7 for simplicity.
