you have to understand this, the Front Side Bus is what you are overclocking, which overclocks EVERYTHING in your system, that you do not set a divider on. That means your PCIe bus, your PCI bus, your Memory controller, and your memory, and anything else that s there.
There is only one way to overclock just the CPU and that is by increasing the multiplier, and only Black edition AMDs, and older FXs series Chips have upward unlocked multipliers, on any other AMD chip, you can only decrease the multiplier, which just under clocks it.
now I am telling you this, right now, since your AMD has a multiplier of x11 your ram will be under clocked by default, this happens for some reason on AM2 platforms with a odd multiplier. So if you have ddr2 667 ram, it will still be under clocked, and will not run at the rated speed.
here just do this, leave everything on on auto, expect for your Hypertransport link, put that at x4 or 800mhz, depending on how your MB has it. Then find your FSB, which should be at stock 200mhz, and raise that up to 220-225, save and quit, load into windows, and run two instances of Prime 95 for about 2 hours, you need to run two different tests in prime because you have two cores and in order for you to test stability you need to stress both cores.
2 hours of prime stress testing with out errors usually means you have general stability, 6-8 hours of prime stress testing with out errors means you have rock solid stability.
