Question Why does BIOS say that CPU Vcore is 2.75 volts and CPUZ says 1.184V?

[RabbitSK]

I recently overclocked a XEON X5460 from 3.16GHz to 3.6GHz on GA-EP35-DS3R and i have 6gb ddr2 ram(2 1gb HP sticks and 2 2gb sticks - one AData and one Kingston) and i wanna know which voltage is right.

Did you mod the BIOS to support the Xeon? Maybe the mod doesn't interpret voltages correctly for the Xeon. You are in a completely unsupported configuration, you are kind of on your own.

Should i turn off CPU EIST when overclocking?
