CPU Speed

well mine overclock at 3.8 if have probs you may have unstable overclock whether with a locked or unlocked processor, you have to tweak the system to get it absolutely stable. This means you have to change the variables (Multiplier, FSB, voltages, memory timings) until the system is stable. This is mainly a trial and error process and takes up most of the time when overclocking a system. Here are some thoughts: Your system will start acting strange if your motherboard doesn’t have a PCI /AGP lock. Having a PCI/AGP lock will keep the frequency of your PCI and AGP bus at 33 and 66 MHz respectfully, even if you raise your FSB. Without this lock, the PCI and AGP bus speeds are increased with the FSB, eventually reaching a point where they no longer function correctly. Some motherboards have this lock and some don’t. Check your motherboard / BIOS for such an option. Remember that increasing your voltage will almost always make your system more stable. But as stated before, your temperature will sky rocket and the components lifetime may be decreased. Therefore, the goal is to find the lowest voltage settings at which your system is stable. Decreasing your FSB a few notches may also provide a stable overclock. Sure, you may not want to lower your max overclock, but lowering your FSB 1-2 MHz can mean the difference between a stable system and a BSOD after 25 minutes of gaming. Sometimes, a very high temperature can cause instability as well, so be sure to keep your processor at a decent temperature. One of the ultimate stress tests is Prime 95

If errors are present, go back to the drawing board. Lower your FSB, increase your voltage, relax your memory timings, etc.
