I give up. :bang: I went from an IP-35 Pro with a Q6600 to a 4790K on an ASUS Sabretooth Mark 1. Sort of like going from a tricycle to a Ferrari. I have been messing around in the BIOS for almost two weeks and I cannot get the motherboard to cooperate with me. I realize the problem is between the chair and the computer so thats why I'm here. I haven't been, you know, "on the scene" for a while. (please note the Spongebob reference) The default settings on the MB put the 4790 to 4.4 at all times with a VID in core temp of 1.2. If I let the motherboard have its way, it auto tunes it to 4.6 and jacks up the voltage to 1.325. Ironically that's the exact VID of my old trusty Q6600. I realize I have a lot to learn. This MB is far more advanced then my old IP-35 Pro. That's why I've been trying to find a good starting point by setting the 4790 to it's default core ratios but I have no idea how to get the MB to do that. It seems like no matter what I change I end up back where I started. I would also like the RAM to use it's XMP profile and run at 1833 Mhz. I have 16GB. I also have a feeling using the XMP profile instead of manually setting the timings may be part of my problem. Any help would be appreciated.
