Thought I would post my settings in case this will be useful for others.
My only use for this PC is for gaming so some of the settings would probably not be suited to 24/7 desktop use. Notably the locked Vcore and locked Clock. But it does make it more stable on my CPU with a lower Vcore.
5930k CPU
CPU Clock 4.4 Ghz
Cache Clock 4.0 Ghz
Ram Clock 2666 Mhz (4 x 4 GB Corsair Vengeance)
Video cards. Two GTX 980's in SLI.
Two 512 GB Samsung SSD's in Raid 0
Antec 1200 Watt PSU
Thermaltake 360mm Water
Bios Settings. Anything not posted is on Bios Defaults.
AI Overclock Tuner = XMP 2666
BCLK = 100
CPU Strap = 100 Mhz
All Core Ratio = 44
Max Cache Ratio = 40
Internall PLL Over voltage = Enable
Fully Manual Mode = Enable
CPU Core Voltage = 1.280
CPU Cache Voltage = 1.200
CPU System Agent Voltage = 1.150
CPU Svid Support = Disable
CPU Input Voltage = 1.850
PCH Core Voltage = Auto
VCCIO CPU Voltage = 1.100
VCCIO PCH Voltage = 1.100
CPU Spread Spectrum = Disable
Dram speed = Auto
CPU Load Line Calibration = Level 8
CPU Power Phase = Extreme
CPU Current = 140%
CPU Power Thermal = 120
Dram Current (Both Channels) = 120%
Dram Power Phase (Both Channels) = Extreme
Intel Speed Step technology = Disable
CPU Integrated VR Fault Management = Disable
CPU Integrated VR Effiency = High Performance
CPU C States = Disable
I think that is all I have changed,
NOTE.These settings are for Ram that is using a Bclk of 100 Mhz. If you are running faster ram that uses 125 Mhz Bclk then you need to lower the CPU Ratio and Cache Ratio. 35 and 32. You will aslo need to manualy set the System Agent voltage around 1.200-1.250 and maybe a bit more Vcore. Also, Don't forget to test your CPU Stability before using XMP for the Ram and overclocking the Cache.
