Please excuse me if I leave something out or its not perfect, I have never made any type of guide before but I am hopeful we can get you better results. Also, this is more for testing to help you find your way than it is to be a fix by any means. These are going to be Brute force style settings, no power savings or protections enabled. You can always attempt to turn on power saving features at a later point if you so desire.
First steps :
Backup your current Bios profile under Overclocking Profiles.
I would recommend uninstalling all software MSI provided that controls Mainboard settings from Windows. (I am fan more of an manual settings within Bios) – you can always install it back later.
Memory modules (ignore this if you already have the right config) Not sure if your using 2 modules(dual channel) or 4 modules(quad channel) Just verify and or install them as according to manual. IF Dual channel = Dimm 1, and Dimm 3. ---- IF Quad channel would be Dimm1,Dimm3, Dimm7, Dimm5. ALSO note – Verify on desktop with CPUID/Z Memory tab and SPD tab that memory timings match your Manufacturers settings. [[[ If they do not match your proper timings then this may need to be set manually]]
Enter Bios setup (pressing DEL chances are you know that already) Hit F6 Key and Load Optimized Defaults. (This will clear any crazy settings you had saved but also will clean out any invalid settings)
After loading defaults, hit F10 to save settings and reboot.
Enter Bios again. Set following settings Please do not reboot until you have set all settings
CPU Base Clock =  (choose this bclk so your ram can synch to 1600 -SEE RAM settings below)
Adjust CPU Base clock strap = [Auto] or [1.25] (both perform same setting)
Adjust CPU ratio =  at 35 should be 4200MHZ (can go up once you verify it can boot)
Adjust CPU Ration in OS = [Disabled] Just in case you have any software that will change settings autocratically
Internal PLL Overvoltage = [Enabled] not really needed yet, but if you go higher multiplier you will need it.
Enhanced Turbo = [Enabled] I found this to be a big help at higher frequencies.
OC Genie Function Control = [By Onboard Button] PLEASE MAKE SURE OC GENIE BUTTON IS NOT LIT!!
Direct OC Button = [Disabled] Takes care of above option from interfering with your overclock.
DRAM Frequency = [DDR3 1333] This should show right below the option in grey whilte set to 1333 strap, you will see 1600MHZ in grey.
Extreme Memory Profile(X.M.P.) = [disabled] Can be changed later but I usually keep off when overlocking
DRAM Timing Mode = [Link] Just to be safe Auto will probably be fine later as well.
Advanced DRAM Configuration - leave all on AUTO unless your memory is being recognized improperly See Memory notes above.
Memory Fast Boot = [Enabled]
Vdroop Offset Control = [100%] Can be changed later but higher is better for higher overclocks – this is overkill for current settings but can be changed as needed later.
Digital Compensation Level = [high] best used at higher clocks again this is for testing now.
CPU core OCP Expander = [Enhanced] Again overkill for low clocks but good for higher speeds
CPU Core Engine Speed = [2x]
CPU Core Voltage = 1.3500v This is variable according to your stability but start here for testing as long as temperature are in valid range. Bring it up for higher clock speeds but each CPU is different so for now testing
System Agent Voltage (SA) = 1.2000v High setting for now at current settings but can be adjusted according to clock speed, again testing for now.
CPU I/O Voltage = 1.2000v high for current settings but good for testing
CPU PLL Voltage = 1.6000v Once done testing this can be set I usually use 1.6000- 1.8000 personally, ive had best luck on previous platforms in that range.
CPU Ovveride voltage = 
DDR CH_A/B Voltage = [1.5000v] Your ram specs indicate 1.5V verify if needed. If your using Quad channel, Triple channel or 8 sticks total you can adjust over 1.5v slightly to increase stability. I choose 1.530 for my ram, which is 1.5310v actual
DDR CH_C/D Voltage = [1.5000v] Your ram specs indicate 1.5V verify if needed.If your using Quad channel, Triple channel or 8 sticks total you can adjust over 1.5v slightly to increase stability. I choose 1.530 for my ram, which is 1.5310v actual
Leave all DDR CH_X Vref Voltages at [AUTO] for now.
CH_A through CH_D Vref = [AUTO] No need to mess with these for now
PCH 1.1 Voltage = [AUTO] no need to mess with these for now
PCH 1.5 Voltage = [AUTO] no need to mess with these for now
OC Retry Count =  Note: Sometimes on unsuccessful overclocks my mainboard will have two faults, it will get stuck in boot loop or turn off completely. Very rare for it to happen but something to pass on.Also if your trying new settings and it continues to reboot, try to wait extended amount of time until it Posts with overclock warning for defaults.
[[[[[CPU Features Menu]]]]]]
Hyper Threading = [Enabled]
Active Processor Cores = [All]
Limit CPUID Maximum = [Disabled]
Execute Disable Bit = = [Disabled]
Intel Virtualization Tech = [Disabled] Enable if you need for software like Hyper SLI (intel x79 already has SLI support)
Intel VTD Tech = [Disabled]
Power Technology = [Disabled]
C1E Support = [Disabled]
Overspeed Protection = [Disabled]
Long duration Power Limit = 
Long duration Maintained = 
Short duration Power Limit = 
Primary plane turbo power limit = 
EuP 2013 = [Disabled]
Cpu Phase control = [Disabled]
CPU I/O Phase Control = [Disabled]
PCH Phase Control = [Disabled]
DDR CH_A/B Phase Control = [Disabled]
DDR CH_C/D Phase Control = [Disabled]
Mother Board LED Control = [Enabled]
C1E Support = [Disabled]
Press F10 – Save and reboot.
Now at this time if it works, obviously you will POST and see BIOS, don't boot into windows but instead enter BIOS and verify changes are saved, and implemented. If all goes well your sitting in BIOS with a clock speed of 4200MHZ and DDR3 @ 1600MHZ
Check CPU Temp and Voltages, if all looks proper then you can exit and reboot. Boot up into Windows and see if you have some level of stability.
If this works you should be able to increase Adjust CPU ratio =  up more. Once you go over 4.3/4.5GHZ CPU Core Voltage = 1.3500v will probably not be sufficient Go up as needed.
Keep all settings as entered earlier, except change
CPU Base Clock = 
Save and reboot
If still no boot success, try
CPU Base Clock = 
Adjust CPU Base clock strap = [Auto]
Adjust CPU ratio =  this will give around 4.5ghz on strap 100x1.0
No matter what happens let use know on here maybe we can change up settings, recommend other options as these are not designed to be fool proof or even recommended by everyone. Each overclocks differently some more conservative than others. As stated most of these settings are overkill for any CPU frequency under 4.5ghz
Also please note if you can Motherboard LEDs, the CPU Phase leds are up above CPU socket in long line of Blue, during testing are you seeing these move or fluctuate. Also big thing to keep an eye on is Debug LED down next to CMOS Battery. When boot failure note what Code is last displayed This may help also.
Hope this helps in some way, let me know how it goes!! and best of luck!
I think the BigBang Xpower 2 is a fairly decent mainboard so I hope it will server you well.
