Look at the 1.650 vcore and the 1.675 vcore settings.
I tried 1.675 to see how high I could go stable at first but the actual result was 1.850
When you look at the 1.850 pin mod you can see that it is the sum of the 1.650 and 1.675 jumpers...but I only had the 1.6750 in place.
Is the motherboard "pre-jumpered" ?
using KM400 based motherboard.

Your other thread mentioned this board was out of an HP. I suspect this is why it's locked, and I would speculate that it would be done in the bios, since it's easier than doing a hardware mod. Years ago with the old style rectangular bios chips I hot-flashed an HP board to the board manufacturer's bios. Doubt I'd dare trying that again these days.

I see. Thanks for the insight.
I guess I would have to understand more about how voltage is applied or selected...There HAS to be a way...I know in the old days if you couldn't get the voltage you wanted, you could just add or change a resistor on the mobo and therefore manipulate what voltage was actually sent to the cpu. Is there commonly a voltage selector circuit on motherboards??
I've also been looking for what pins voltage and ground are applied...I mean if it comes to that, there should be some way I could supply about 1.6v with enough current to support the cpu. Found some pdf data sheets but cannot view them from this location..arg. Will just have to wait.
