Overclocking: Only With Increased Northbridge Voltage
Overclocking the new Intel chipsets cannot be done in a snap. This is demonstrated by the fact that almost none of the manufacturers are able to operate their boards significantly above the normal 200 MHz. One of the key methods is to increase the supply voltage of the MCH chip. Both the 915P and the 925X work according to specification with 1.5 V (see above). The range from 1.425 to 1.575 V is within the tolerance. What the manufacturers presented to us for the test was in some cases higher than the Intel specification. The following table summarizes our measurement results:
