I'm going to start off with the 4.6ghz 1.200v test and work it out from there. Both of them mentioned only tinkering with vcore, LLC, DRAM settings, and a few others....but they mostly emphasized that most settings can be left on "auto" and it would take care of itself. Anyway, are there any "other" settings I should manually define if I hit a brick wall in my OCing adventures? I already got vcore, DRAM, LLC, and a few others in mind....I'm just wondering about those "other" settings that are crucial to Haswell
Thanks in advanced. Hopefully I get a nice OC without temps sky rocketing. I don't plan to delid either.
IVR-Input voltage can help a lot. Digital and Analog io's too if you give them a small boost. I put them up a bit before, my 4.5 oc was rock solid with them at +0.1v, hours of prime, 50 runs max ram IBT all the likes; i went to put them down and bluescreened on the windows load screen, so nope ;p
Don't judge your temperatures on stress tests with AVX enabled. Either run them with AVX disabled or use x264 as a guide for temps, something like that.
Stress tests with AVX enabled seems to create a massive artificial temperature rise of as much as >20c, which led to a lot of the talk that haswell runs really hot, when the temperature gain is not present in any real world application as far as i know (with or without avx) leading to overclock that, for example at a set voltage and clock, will not pass 70c under 100% CPU load with x264 (lets say 1.2v on a h100i - very reasonable) but will hit 94c+ and thermal fail on a stress test with AVX enabled. Stress test without avx enabled, temps are more normal, and toggling avx on/off does not seem to have SIGNIFICANT changes for thermals on anything aside from stress tests
Using this i was able to take 4.7ghz on ~1.34vcore on a silver arrow, re-enabled avx and my temp maxes are in the 80's with x264 full CPU load with HT, a bit cooler than prime95 small fft-with-avx-disabled
