I'll start off by saying that I am a novice in the world of overclocking, but I have done lots of research before coming here to ask for help. I am trying to achieve 4+ ghz cpu and 2.8ghz+ NB, but am stuck at 3.8ghz cpu and 2.6ghz NB.
My current stable OC is this:

For my current stable settings, vcore is @ 1.345v and CPU-NB @ 1.24v and NB @ 1.1v (stock). My NB multiplier is at 13x giving me 2600mhz. For cooling I am using Hyper 212+ and @ 3.8ghz idle temp is 36.5c and load max is 50c.
Notable ? BIOS settings: C1E disabled, CnQ disabled and smartfan target disabled (these settings off force my CPU fan to run at max), chassis intrusion disabled, spread spectrum disabled, advanced clock calibration disabled.
My memory is recognized @ 1333mhz but is specified for 1600mhz, which I manually set in BIOS to 1:4 ratio. Ive messed around with the timings (as seen in above image) based on what Ive seen on forums for my specific model, and I think maybe my timings and speeds are causing problems when I try to achieve 2800mhz NB?
I have been trying to achieve a stable OC of 4ghz+ but I cant get above 3.8 without crashing under stress tests. I've been using AMD Overdrive stress test, and at 3.9ghz it crashes after 5+ minutes, and at 4ghz it crashes within 10 seconds of testing. Also, I havent been able to get my NB above 2600mhz even with voltage tweaking in increments from 1.25v-1.35v, it crashes within 10 seconds of desktop at 2800mhz, and sometimes even freezes my system and forces me to reset CMOS cause it wont POST.
I've included a lot of information here, let me know if you need more info. I appreciate any help/advice!
