Overclocking the i7-4770K and Asus Maximus Hero VI

I just wanted to see what difference overclocking would make using the i7-

4770k processor and an Asus Maximus Hero VI. Read everything I could find

and watched several videos and was successful only up to 4.2Ghz at 1.25V.

after that just the blue screen scenario. So my question is why do I read

others with the same build do better? It really doesn't seem that

difficult. The computer will run FSX fine as well as the load test or

crash. I am using a three monitor set up with an EVGA GeForce GTX770 4GB

card and the G.SKILL 8GB (2 x 4GB) Ripjaws X Series DDR3 1600MHz PC3-12800

Memory.Don't get me wrong even 4.2Ghz makes a difference and is running

just as cool a temp as the default bios just can't seem to take it any

higher. Something I should upgrade maybe like the memory or the three

monitors come in to play.

My Build:
Intel Core i7-4770K, ASUS MAXIMUS VI HERO Motherboard, , 8GB Memory , EVGA

GeForce GTX 770 4GB Video Card,Corsair Enthusiast 750W 80+ Bronze Certified

ATX Power Supply,Windows 7 64bit, Corsair Hydro Series H55 CPU Cooler:)

I have a similar build with a 4770k, an Asus Maximus VI Gene, G.Skill and Win 7. I could push 4.6GHz but was not stable long run and heat was not worth it so settled on 4.5GHz for last 3 years.

Refer to my Hawaiian build in sig for more info!

The heat didn't seem to be a factor yet for me. I boosted the voltage up and still wouldn't run long without crashing if it booted up at all. 4.3 would load windows at 1.29V but not last and did run hot. Now at 4.2 and 1.25 it seems to even run cooler than the factory auto and I can see an improvement but unlike you no way I can get what you have for some reason. I am rather new at this so I might be missing something.

I took into account 17 factors on the mobo to get to 4.6GHz:

01. Ai Overclock Tuner => XMP Profile
02. Asus Multicore Enhancement => Disable
03. CPU Core Ratio => 46
04. Min. CPU Cache Ratio => 40
05. Max. CPU Cache Ratio => 40
06. DRAM Frequency => 2400MHz
07. Timings => 10 -11 -11 - 28 - T1 - 1.65v
08. CPU Current Capacity (in DIGI+ Power Control) => 130%
09. DRAM Current Capacity (in DIGI+ Power Control) => 130%
10. LLC => Level 7
11. CPU Core Voltage Override => 1.345v
12. CPU Cache Voltage => 1.25v
13. CPU System Agent Voltage => 1.25v
14. CPU Analog I/O Voltage => 1.25v
15. CPU Digital I/O Voltage => 1.25v
16. Eventual CPU Input Voltage => 1.9v
17. CPU Spread Spectrum => Disable

You need to work within these. It's not just about upping vcore only to max your OC.
