Hi everyone. I've been fiddling with my new build for the past month, seeing where I can get a healthy overclock. To start with I will display my system specs:
Haswell i5 4670K
MSI z87 G45 Gaming Motherboard
Xigmatek Dark Knight II cooler with two SP120 fans in push/pull
Corsair Vengeance Pro 16GB (2x8) 1866MHz 9-10-9-27
Samsung 840 120GB SSD
WD Black 500GB 7200RPM HDD
MSI GeForce GTX 780
NZXT Hale 90 V2 850W 80Plus Gold Certified PSU.
NZXT Switch 810 Case fully loaded with fans. Superb Airflow, simply put.

When I first put the build together I had a fine overclock at 4.2GHz with core voltage set to about 1.7-1.8V. Never had a BSOD. I play Farcry 3 and Battlfield 3 quite often, and crysis 3 sometimes. Farcry 3 and crysis 3 have never crashed on me. Battlefield on the other hand, always crashes. it is the famed "faulting application name bf3.exe..." error. Never the nVidia driver, always bf3.exe. I'll tell you, no matter how long you search, you WILL NOT find a real solution to that error.. Besides that point, the closest I came to finding a solution was that the CPU was not overclocked fast enough (based on other people's findings). So I am now here looking for a faster and more stable overclock.

This is what I have done so far:
I have set the multiplier to 44x (4.4GHz) and was getting BSOD until I set the CPU voltage to 1.21V, and no longer BSOD.. or so I thought. Core Voltage Mode is set to Auto for stress testing but when I game I usually put it on Adaptive. I use Prime95 for testing, and aida64 cpuid and cpu-z for monitoring other stuff.

Basically, I ran Prime95 small FFT's and Blend for an hour each with no problems. At the time, I was on a bit of a time crunch to run each test longer, so I figured I would just run small FFT's, large FFT's, and blend, each for an hour to start with. Later I will run longer times when I know I will be around to keep my eye on things.

I ran the large FFT for approx. one hour and the results said everything passed. I noticed that it was just the "pentium 4 FFT" though and it immediately jumped into "core 2 FFT" tests, and within two minutes I got a BSOD.


Here are the results I got from Prime95 from the "pentium 4 FFT":

By the way, I am new to all of this so I am still learning what everything means.

I am looking for suggestions to help achieve a stable 4.4GHz overclock, regardless if it fixes my BF3 crash problems, and yes I have re-installed the game, repaired many times, re-installed origin, made sure all drivers up to date, made sure the trademark logo was deleted from the installer folder, everything that has been done before has been done.

What I have done so far since the previous BSOD is increase the Voltage to 1.215V, I prefer small increments. As I am writing this I am currently running another test on the "core 2 FFT" where it had previously failed. it has been running for about 25 minutes now and so far so good but like I said I'm new and looking for a bit of guidance in this matter.

Prime95 results for the "core 2 FFT" thus far:

By the way, my idle temps are ~35C, and full load temps during Prime95 are a maximum of 66C. It has never gone higher than 66C, which is just fine.


Sorry for the long post, just trying to be thorough :)
As seen in bold above, I would very much appreciate any suggestions and help. Thanks
