I've been having some serious trouble trying to find out HOW exactly CPU Reference and MCH Reference relate to CPU Termination, what they do, and how any of these three settings would affect an overclock. Here's an example - My system (exactly whats in my sig) is running 1600mhz FSB, 3.8 GHz E6300 Wolfdale (400 x 9.5), and I am using a 2.66D memory multiplier on the EP45-UD3L mobo for my memory to reach 1066 MHz. I notice when raising the CPU Termination voltage that the CPU Reference and the MCH Reference voltages also climb up at the same time in the BIOS. So could someone with some real expertise actually tell me how you would decide what values would work the best between Termination and References? I mean how much of a value is recommended on Reference voltages for comparison to Termination voltages? I am SO confused right now.. My VCore is running at 1.3625v with LLC disabled for the 3.8 GHz speed, and I want to go to 4.0 GHz for daily use. BUT my goal is to keep the VCore as low as possible. And to do this I was wondering if Termination and Reference voltage changes will help? Please someone help me here to get these voltages right, and tell me if they even should be changed at all. I have done extensive searching on this subject but have found almost nothing. Thanks.
