Ntune seems to have … uhm, issues. I ran it on coarse a few times and when it finished there was absolutely no evidence of a run. I’ve run it on Fine a couple of times and it gets to a point where it runs for 1-2 hours with the same values in the Progress / Results window. (+2% FSB, +-4% AGP/PCI).
Is it adjusting voltage settings in the background? Or have the memory settings effectively rendered it unable to write to memory so it keeps operating off the previous values?
