whea uncorrectable error only when streaming (OC related?)

Hello,

I've been getting whea uncorrectable errors (bsod) after about 15 minutes of streaming using the Open Broadcaster streaming program while playing Far Cry 3. It happens consistently, but without using Open Broadcaster or streaming, I can play perfectly fine with no issues with any programs. This seems to imply it's the Open Broadcaster program causing the crashes, but as a whea uncorrectable error is a hardware failure, I don't believe this is the case. I haven't tested to see if it crashes while streaming any other games.

I've overclocked my CPU using the 4 way optimization asus program using the 4.2 ghz preset OC, and I haven't experienced any issues with it till the crashes while streaming just recently. My guess is that nothing has taxed the CPU enough to have it display the instability from the OC till I started streaming; does that seem likely? The temperatures on the CPU are around 50 though, so it's not overheating. I didn't test the OC with any kind of stress program after I OC'd it, so the streaming would be the first true stress test of the CPU other than just games like Far Cry 3 and the like, which aren't going to hit the CPU much.

My system is a i7-4770k CPU and SLI Palit GTX-780 Super Jetstream 3GB GPUs which are factory OC'd to 980 mhz.

My current plan is to reset the bios to revert the CPU back to not OC'd, and then test to see if it still crashes when I stream Far Cry 3. Would using the load optimized defaults from the bios reset the OC or do I need to use the jumper on the mobo?

Also, does it seem like the OC is the most likely cause of the bsod, or could it be the Open Broadcaster streaming program causing it, even if it's a whea uncorrectable error, which as I understand it, is hardware related?

In addition, if the crashing goes away without the CPU OC'd, I'd like try and manually OC it this time, but I'm not looking to super tweak it, I'd just like to get it back to 4.2 ghz, but stable. Is it possible for a i7 4770k to be so bad it can't be stable at 4.2 ghz?

Thank you very much to anyone who can answer one or all of my questions. Your help is very much appreciated.

- yes, it definitely can be a possibility.

- loading optimized defaults would work just fine. use jumpers if you can no longer boot.

Also, does it seem like the OC is the most likely cause of the bsod, or could it be the Open Broadcaster streaming program causing it, even if it's a whea uncorrectable error, which as I understand it, is hardware related?
- although i wouldn't point to one or the other being the cause of a BSOD in this case and rather both being used in conjunction being the cause but, if you haven't stress tested the CPU with a program such as AIDA64, it may definitely be your OC. i think OBS is quite solid for being an open source program; it did have it's fair share of problems but, that was way before during the early stages of OBS (if you're using a beta version as of right now, you could try going back to a stable one). i also use OBS on a consistent basis with Battlefield 3 and have never had reason to deem it as the cause of BSODs, crashes and etc.

Is it possible for a i7 4770k to be so bad it can't be stable at 4.2 ghz?
- i wouldn't say it's bad but, i can definitely see it being somewhat limited but, not @ 4.2GHz. the average Haswell 4770k should be able to hit 4.5GHz or maybe slightly under with the good quality 4770k's being able to push 4.7GHz+
