You can push your ICH up towards 1.38v to see if that helps. I don't think increasing those voltages will help, but you'll have to test it out on your end to be sure.
Have you tried increasing your PCIe Voltage frequency? You can push the IOH to around 1.26v and the ICH to around 1.70v safety.
I'm at 4Ghz as well with my X5660.
OK your settings don't work for me for some reason, as my BIOS does not have those voltages to select.
PCIe voltages for IOH and ICH do not match what you have. Below is what I have to work with.
IOH PCIe Voltage Min: 1.51v Is minimum and what I was already at, so I cant select 1.26v, it doesn't go that low. Min/Max is 1.51-2.78v. I do not see an AUTO setting.
ICH PCIe Voltage Min: 1.51v is minimum again and what I was already at. I can't go to 1.70v as you suggest because the max setting is 1.61v before it turns yellow (which is what I am at now). Min/Max is 1.51-2.05v and anything above 1.61 turns on the scary Yellow warning thing. I want to avoid using Yellow settings. I will try 1.61v for now as I already tried everything below it.
IOH/ICH Voltage do not have an AUTO setting. It only lets me enter numbers. If I enter "nothing" it auto "hard sets" the minimum voltage on the chart on the right hand side of the screen. I was already at the minimum voltages and Windows does not work at those voltages, so I was increasing voltages slightly over the last few days since that is the ONLY direction I can go. I can't figure out how to lower past the minimums in my bios. lol, how do I get past those BIOS minimums exactly?
