cant seem to pass post @ 3.5ghz
with 1.32-1.35v cpu voltages. any advice?
What board is that karl and how much is vdroop a role? With gtl volts set just as they are, try raising vtt to 1.3v. Depending on the board's bios your gtl ref settings may be linked to vtt so watch that they stay as is. Really more info about your system ,ram model and frequency, board model, things like that, could help people make better suggestions.
