That probably is a weird question, but I can't turn off the OC on FX8350. There is simply no option for that in my motherboard bios (MSI 970), and I couldn't find anything in AMD Overdrive tool either. I reduced the frequency and put the voltage to it's defaults, but apparently it's still isn't enough 'cause it's still unstable. And I'm pretty happy with it's stock 4.0Ghz... I'd appreciate any help from you guys.

If you reset the BIOS to its default settings, there should be no OC involved. Like I say, Turbo Mode isn't really OC'ing. It is simply increasing the clock speed of some cores when others aren't needed. At any rate, there's no reason you would need to disable TM if you aren't OC'ing the processor yourself.

Your symptoms don't necessarily point to an OC'ing issue, and wouldn't be caused by OC'ing if you don't in fact OC. How is the rest of your system for software...

I already disabled it, didn't help, it's still unstable. Even though I put it back to its base clock (200x20)... Apparently its overclocked by default, isn't it? Should I just increase the voltage?

Its base clocks are not OC'ed, exactly. As fewer cores are needed, the ones that are in use may have their clocks increased a bit... as long as the CPU stays within its power envelope (TDP).
Nevertheless, there should be no reason the CPU is unstable at stock clocks, unless you got a bad one. Highly unlikely, but possible. More likely the motherboard. What exactly are your instability indications?
Is this your board? http://us.msi.com/product/motherboard/970-GAMING.html#hero-overview

Yes, thats the one.
The sympthoms I've seen were severe game crashes (all of them with mostly Access violation or Invalid pointer errors) and some rare random bsod's. Their occurance frequency varies with OC settings, so I just figured it must have been it.

What are your temps? You could also have a stick of ram going flaky. You should be able to use this.

http://www.memtest86.com/

pull all ram out except one stick, run it for say a pass, see if you get errors, if not, pull that stick move to the next one until you go through your set. If you have a stick with errors, it will quickly become apparent which one.

Your symptoms don't necessarily point to an OC'ing issue, and wouldn't be caused by OC'ing if you don't in fact OC. How is the rest of your system for software conflicts? Run CCleaner and do the Clean and Registry portions both. https://www.piriform.com/ccleaner
Then get rid of poorly written malware that may causing the crashes with something like Malwarebytes: https://www.malwarebytes.org/antimalware/
Finally, if you have a lot of stuff sitting in your tray, disable as much as possible. Everything starting with Win steals clock cycles and has potential for producing a software conflict.

Wow, I'll try all that, thanks.
Also, I've noticed my bus speed is on 199.7 all the time, while it was supposed to be 200. Could that be a reason of the problem or does it even matter?

It doesn't matter. 200 MHz is just a round number. My AMD boards have all run from 199.x to 200.x MHz.

Okay, here's what I did.
1) Ran the memtest with each stick, no errors.
2) Reset the BIOS settings.
3) Uninstalled realtek drivers, ran ccleaner, installed them again.

After an intensive gametest, which lasted about 8 hours (at some point I'd just leave it running for an hour or two, and then would come back), without a single crash.
I almost thought that was a victory, when lately I had a crash (0xc0000005 as usual) and then a BSOD regarding dxgmms1.sys . I reinstalled all my drivers again, reset the bios, a-a-and... I'm still having crashes, but like every 5 minutes now.
Is there a way to check the integrity of the drivers, by the way? Or can we only guess, if they're corrupted or not?

P.S. Might be a coincidence, but that BSOD occured the same day I turned off the turbo mode. I forgot to do that before.

So I was offline for a while, but I did check the disk and there were no errors reported either.
So, a little summary:

1) Harddrive and RAM were checked for errors.
2) Drivers were reinstalled.
3) BIOS setting were reset to default.

Yet the frequency of the crashes has gotten even worse, they occur literally every few minutes now and not only in games. At least they all have the same exception code - c0000005 . Also, I had few BSODs with mostly 0x50 error (PAGE_FAULT_IN_NONPAGED_AREA) with dxgmms1.sys . WhoCrashed couldn't identify the responsible module or driver.
Now that I've said that, I think I might try reinstalling graphic drivers again and DirectX... Though, at this point I'm completely lost and not sure if anything is gonna help.
Anyway, I'd still appreciate any ideas regarding that problem, guys. Thanks for your time and effort too.
