Overclocking

Being an LX chipset motherboard, you can already tell that the LE370 is a bit less than an overclocking phenomenon. There is a twist on the LE370, though, as it offers 60, 66, 68, 75, and 83 MHz bus speeds. For any of you who are interested in underclocking your CPU, here's your way to do it! The other less common bus speed is 68 MHz, which is the 3% increase commonly used by manufacturers and system integrators to test the tolerances of their products. This is almost definitely included as a CPU speed/stability test. Either way, it is not very useful for overclocking, as the performance gain is nominal.

What's left are the two settings that are becoming standard in the 66MHz FSB world: 75 and 83 MHz. While these speeds have been found to be pretty successful with overclocking, we run into a whole other set of issues regarding system stability, AGP and PCI ratios, and the likes. See the Overclocking Guide to see what I mean. Additionally, by having only 75 and 83 MHz bus speeds, this rules out some overclocking possibilities, such as the 300 to 450, 366 to 550, etc. attempts. One thing we would like to see are intermediate speeds between 75Mhz and 83Mhz, and 83MHz to 100MHz.

Of course, overclocking the LE370 is simple to execute because of the "Jumper Inside" technology. Similar to SoftMenu, but with fewer configurable options, Jumper Inside allows you to use factory defined presets, which configure the final CPU speed through preset multiplier and bus speed settings, or a user defined setting. The factory defined settings on this board were all 66 MHz, being the only "legal" bus speed that this board supports. The multipliers range from 3 all the way up to 8, so this motherboard can support up to (and has a factory default for) a theoretical PPGA Celeron 533. The user defined setting is the same old, same old that you are used to. Choose you multiplier (now rather obsoleted due to multiplier-locking on today's CPUs, and choose your bus speed. Then see if it boots.
