It appears that I may be unlucky with my 5960X. No matter what I try, I can't seem to get it to OC. Can't even OC to 3.6GHz! I can, however, run at 3.5GHz with XMP on (3000MHz DDR4). I've used the tips from this thread, among others...only thing I can think of is maybe my PSU (currently: Seasonic X-1250 1250W). That's very unlikely - but I have a AX1500i on the way, anyway. I've pumped as high as 1.375v CPU/2.1 VCCIN/1.35V RAM - 3.8GHz crashed after about 6 minutes of ROG RealBench. Didn't bother going lower - no point in OCing with that voltage if it's for 300MHz (runs at stock voltage at 3.5GHz/3000MHz DDR4 XMP). Temps are fantastic. Just not a CPU that will comply to any OC. I just can't really believe it. Going to keep at it...but it has been a few days of try/reboot/test/reboot/re-try..
- Tried 45x100, 1.35v VCORE, 1.95v VCCIN, 1.35v DDR4 and went back 100MHz at a time - went as high as 1.375v VCORE and 2.1 VCCIN. Went as low as 3.7GHz and quit trying (may as well run stock at that point). Using ROG RealBench with 1 hour of success as a benchmark for a stable OC.
- Temps never an issue (except at higher voltage - just high then - in 90s) - so thinking it's just a dog CPU.
- Now at XMP (hence the BCLK) at stock speed for CPU.
Specs:
Intel i7-5960X CPU (Corsair H110 280mm Liquid CPU cooler), Corsair Vengeance LPX 16GB 3000MHz DDR4, Tri-SLI EVGA GTX 980 SC 4GB, Creative Sound Blaster ZxR audio, Samsung 850 Pro SSDs (256GB; 1TB), and a 2TB Western Digital Green WD20EARX 5400RPM HDD on an MSI X99S XPOWER AC motherboard inside of a Cooler Master CM Storm Trooper full tower – powered by a Seasonic X Series X-1250 (1250W; fully modular).
BIOs screenshots (with 3.5GHz/XMP - but the only things I'm not using are CPU core, VCCIN, DRAM CH_A/B, DRAM CH_C/D which I have altered previously for my OC attempts).

Any thoughts?
