Well, there's lots and logs of OCing guides in this forum and others. I can also recommend the User Guide - NVIDIA nForce 590 SLI Technology Chipset Overclocking which you can download from the nVidia website. They use a Foxconn board but the process is essentially the same.

First off, make sure your rig is stable, run Prime 95 or Super Pi or something like that for 12 to 24 hours without failure. Do whatever it takes to get stability.

The OCing controls are in the BIOS under the Advanced Tab. First off you need to set AI Tuning to Manual under the Jumper Free Configuration Screen. That will unlock the OC controls.

Basic process -
Find max CPU speed. Either lock or set down whatever you can other than the CPU Reference Clock. This would include the CPU Multiplier (set to at least 2 or 3 below default for your CPU), PCIEX16_1 and 2 (lock at 100), under CPU Config - DRAM Config - Memory Clock Frequency (set down at least one setting below default, maybe two), under Chipset - NB to SB HT (lock at 200), CPU<->NB HT (set to 4, maybe 3), you can leave the rest alone.
Then start raising the CPU Reference Clock. Might as well start out with at least 220 to 230 or so. Reboot and establish quick stability (running stability programs for 10 to 20 minutes). Raise the CPU Reference Clock 10 MHz, reboot, establish quick stability, repeat until the machine won't reboot. Back off the CPU Reference Clock a bit and try again. If it passes quick stability test, go for extended stability. Keep backing down until it passes extended stability. Then inch it up a tad and go through the testing. Repeat raising and lowering and stability testing until you are sure you have the highest CPU Reference Clock you can with Stability.
Next, lower the CPU Multi to 4 or more below your default, lock or set down everything again except set your Memory Clock Frequency to 400. Start raising the CPU Reference Clock. Essentially go through the same process but this time its to see how high you can push your memory. However, this time when you get as high as you can with stability, start loosening or tightening the latency settings to fine tune it.

Now you can compare the two highest settings, for CPU and for Memory and decide what's best for your situation. Run a couple of benchmarks and perhaps some hard games to see what kind of FPS you get with each. Then start compromising between the CPU clock settings and the memory settings to get the best overall scores.

This all takes a lot of time. Days, weeks even, depending on how maniacal you are. There are dozens of settings you can play with.

Read all the other guides for pointers and tips and suggestions. Keep at it until you are satisfied you have done your best. Then buy a new CPU and better memory and repeat. Keep doing this until you have exhausted all your money, lost your job, alienated all family and former friends. Turn to a life of crime to support your habit. Break into the Cray labs and steal their best machines. Take over IBM so you will have Blue whatever it is currently for your own evil uses. Enslave the world and force all humanity to toil endlessly creating the fastest computer ever and then making a faster one still. Reach out into the galaxy to continue your quest. Then other galaxies, eventually the entire universe. Who knows, by then we may be able to find other universes or different space-times. Go for it!

I was using the m2n32sli with the same ram you have. With the 4200 chip you should try 250x10, ram at 800 Mhz, to give you 2.5Ghz cpu and 1000Mhz. Set HTmulti to x4 and I think you should be able to run that with no voltage changes. If that works try running higher HTT with x3 multi and a bigger ram divider. The ram divider is different when you are using different cpu multipliers. For example if you use x10 cpu multi and DDR 667 max mem speed you will end up getting a /6 divider on your ram. But if you use x11 cpu multi and set to DDR 800 max mem speed you will get the same /6 divider on the ram. Look up the table with all the different dividers. With that chip and that mobo/ram I think you should be able to hit around 280 HTT.
