The only thing to really do in the meantime is read up on overclocking and look through the manual online.
then Downloads then Manual.How to get to 4.0ghz on a Core i7 920
Other than that I find reading through other people's threads where they ask for help overclocking their 920 is the best way to learn. For instance, things I've learned in the last few days is that the Core i7 920 is stock at 20x multiplier with a base clock of 133mhz and if Turbo mode is enabled the multiplier will jump to 21x on one core for a short period of time. What I didn't know was that on our motherboard we can bypass the Turbo mode and actually just set the multiplier to 21x at all times on all cores. Our new stock is 2.793ghz, just because we have the RIIE.
Things I've already known is that Loadline Calibration (LLC for short) is good to have on as it keeps the vcore(CPU Voltage) stable even under load. Adding vcore will add stability to higher clocks, but it also increases temperatures. So the best way you are going to go about overclocking is setting LLC to Enabled and setting the voltages at stock, but not on auto. Then increase the base clock by about 5mhz. This has increased your CPU speed by 105mhz, but also realize that this has increased your RAM speed. You want to keep your ram right around stock to start with (Do not overclock the CPU and the RAM at the same time. It creates alot of headaches). You may even consider running the RAM lower than stock just to keep it out of the equation. In windows, run LinX for 10 passes on All Memory. If it passes, then increase you Base Clock by another 5mhz (CPU speed increased by another 105mhz). However, if it failed add one notch (0.00625v) to your vcore and retest. If it continues to fail keep adding one notch until it passes. If you just keep adding and nothing is helping, then come back here and we'll help you out (More than likely you'll need to increase QPI Pll voltage). You keep this process going of slowly increasing the base clock(making sure that you are keeping the ram speed low) and testing for stability with LinX. Eventually, you will find a point where either you are just happy with your overclock, the temps are becoming unreasonable (80C+), or you have reached 1.45v (This probablly won't happen); then you are done overclocking the CPU and you can raise your ram speed to stock...then retest for stability. If it fails, then most likely you need to increase QPI Pll voltage. If it passes, then try overclocking your ram speed and see if it continues to pass LinX, but do not raise the DRam voltage above 1.65v (1.65XXX is fine but try not to go much above 1.66v). Once you can't increase the ram speed any higher (It might be that you can't raise it at all), then try tightening the timings....once you get there just let us know and we can help you out with that a little more.
Once you are completely done overclocking, I like to run prime95 on Small FTTs for 12hrs just to rule out any other problems.
