I have an E6400. In the BIOS under CPU features it has 6 different ones. Thermal control Limit CPU ID Max Value C1E Function Execute disable Bit Virtualization Tech EIST Function I just bought an E8400 which I have to RMA as the temp sensor is stuck on 103C. One thing I noticed when first setting it up was the Virtualization Tech and EIST function were missing.. I was just curious if anyone knows if they are unavailable in the 45's or if it was a part of this CPU's issues. Thanks. Specs in profile.
