Nice, it's working. I'll try higher freq tomorrow and launch some bench.

If it keeps failing, should I keep increasing the Ring Ratio ?

Not comfortable with the Ring Ratio, is it the cache freq ? (I would like to understand why increasing Ring Ratio solves my problem)

Thank you very much.

Setting the ring ratio to 32 should be a small decrease compared to auto.  I believe leaving it on auto at stock clocks is 34.  As you increase CPU clock speeds, it increases the ratio a little.  And it seems that in your case, it increases it to much at a 4.0GHz OC.  It might be 35 or 36 at that point.
 
You're correct, it is the cache frequency.  You will not see any real world difference with this setting.  Once you find your CPU clock freq you plan to use and get it stable, you can then try increasing this by 1 at a time to find the max stable setting you can go.  But if you're at 32 or 33, you're fine there.
 
I should add that your CPU could have a slightly weaker memory controller and that is why a slightly lower ring ratio allowed you to run at 4.0GHz.

Thanks for the response. Turbo is enabled and I just went into OC control for each core and set them 40. Bios is showing 4.00Ghz OC, however both CPUz and HWinfo Show me a max clock of 3.7Ghz.
 
Update:
 
Ran Fire Strike and HWinfo is showing max turbo clock of 3.991Ghz to be exact.
 
 

Sounds like you're good to go...  You may be seeing a lower clock speed at idle as compared to being under a load if HWinfo shows 3.991 during Firestrike.  The default bclock is 100MHz, but sometimes can fluctuate a bit.  Must have been 99.77 or so instead of 100.

Hey y'all! 
Can someone with bclk / memory OC experience help me out here?
Have the x99 classified with 5960x multiplier @ 40 for 4ghz
G.skill tridentZ 4266 set to XMP-1 for target speed of 3200mhz.
 
 
I am struggling to figure out how to achieve the 4266 (or near) speed on my ram. The mobo manual says anything above the max 3200mhz setting requires bclk OC but
1. I have no idea what to do for bclk
2. if I change it at all (CPU set auto or multi to achieve 4ghz) I get a boot loop that doesn't even get to post.
 
One thing to note: some times when booting into BIOS, bclk may randomly be set to 125, cpu multi back to 30 for 3750 and new mem target speed of 4000mhz. I don't know how to duplicate the random event but I usually set it back to 100 as I feel blck affects my already OC'd GPU (1080) and read that blck also affects all pci devices.

Here is a quick overclocking guide for the EVGA X99 motherboards! Overclocking these boards are similar to Z97, so if you are familiar there, you should be familiar here  Regardless, here is a really quick/easy guide for basic overclocking on EVGA X99.
 
Hardware used:
EVGA X99 Classified
Intel 5820K CPU
DDR4 2133MHz
 
1. Press delete to enter the system BIOS when system boots.

 
2. Main screen will be the Overclock section, scroll down to the CPU Multiplier Control section you can use the mouse or keyboard to navigate here. Change CPU Multiplier Control to Manual.

 
3. Set a CPU Multiplier setting, for this demo we used 42. Remember that BCLOCK x Multiplier = CPU clock, so this means we are running 4200MHz.

 
4. When overclocking your CPU, you may need a higher voltage to achieve stability. To do this navigate to the CPU Voltage Mode section and change the Voltage Mode from Auto to Override or Adaptive. The differences are as follows:
     a. Override mode will force the CPU voltage to run at set voltage during all scenarios, even when system is idle. This will keep the voltage locked but may run the system at a higher temperature during idle.
     b. Adaptive mode will set a voltage OFFSET from the current running voltage. Example: If CPU voltage is 1.050V, setting +50mV will run CPU at 1.100v

 
5. Head to the Memory section to set your memory frequency, you can enable XMP if your memory supports it, this will automatically enable the correct frequency and timings

 
6. Save and Exit the BIOS and Boot into Windows to stress test your overclock. Don’t forget to watch your CPU Temperatures! Hint: If you want the CPU clocks to stay at full performance mode without dropping while in Windows, change your Windows Power Options to “High Performance” mode:

 
And with that this is the basics of overclocking on EVGA X99! Of course things can get a lot more advanced if you are doing more aggressive overclocking, where additional voltages to various controllers or better cooling may be needed!

I also have a problem setting my memory to the XMP1 profile which is supported by my memory. When I set my CPU multiplier to 35, and set my memory to XMP1, the system goes into a loop and never boot. Even leaving my CPU untouched and just try XMP1 for my memory, same result. Any idea why?
