Yeah, that's fine. I guess you found out how to change the multi setting...
Here's a general steps to take when you're trying to overclock your system. I wrote this quick one a while ago...
First, you need to find out what your max FSB is without CPU in the equation. Set the multi real low, like 8 or lower. Then set your memory timing to most aggressive. If you have PCI/AGP bus lock, lock it to 33/66 MHz. Now run memtest86 and see if your memory passes. Raise the FSB slowly if your memtest86 continues to pass. Once memtest86 fails, then raise the VDIMM one notch. Usually 0.1 V. Run memtest86 again. Repeat this step untill you can't go any higher w/ FSB. Most memory can usually take the highest voltage mobos can dish out. You can relax the timing of the memory to get higher FSB, but unless you get much higher FSB with relaxed memory timing, it's better to leave it at tight timing. Once you have the highest FSB, make a note of it. This is your highest possible FSB with your memory. Now, set the multi to something that will make the CPU run just a little higher than stock speed with the new FSB. Does it boot up ok? At this point, you can raise the multi and run Prime95 to see how high you can raise the multi and run the system stable. Once you get error from Prime95, raise the Vcore and try again. Once you can't raise the Vcore anymore or choose not to (because of heat), lower the FSB just a little bit. Run Prime95 overnight to see if it runs stable. Now, your new multi x FSB is your CPU speed.
