Problems with overclocking FX8350

Hello, i'm trying to overclock my FX8350 up to 4.4GHz but it doesn't give me any good outputs, for example when i Overclock it via. Bios it turns off and on but then there is no boot.

My Rig:
PSU - Corsair 850TX
MB - AsRock 990FX Extreme 4
RAM - 4x4GB Corsair Vengeance @1600Mhz

  1. The overclock is not stable. You will need to add more voltage to the v-core in order to make it work. But the FX CPUs are very hot. What CPU cooler are you using? If you are using the stock cooler that comes with the 8350, then you wont be able to overclock it and keep your temps manageable.

  2. I would love to tell you what cooler i have got but it's a Thermal Take one, how to increase the vcore?

    I am not familiar with your motherboard bios. But somewhere near where you bump the clock speed multiplier up to 44, there will be a v-core setting. It may be under a sub-menu called voltage or something like that.

    I am not sure what your current voltage settings are, so I don't know the base line, but I would up it by .01 to .05 volts. For example, if the volts are 1.35, then you could change it to 1.36 up to 1.4. It depends on how patient you are and how worried you are about your chip. You really don't want to apply more voltage than necessary as more voltage creates more heat and more heat can shorten a CPUs lifespan.

    Some people are very conservative and would only go up at .01 intervals until it is stable and temps are good. I would just add .05 to whatever voltage you have and see if it will boot. If it does, then I would run a stress test and watch my temps. If my average temps go above 80C, then I like to back my voltage down, which usually means you have to drop you clock speed down too. So it depends on your cooling.

  4. I'll try to do what you're saying later as i have got things to do right not, thanks for advice.
    P.S. what do you recommend to do stress tests?

  5. Prime 95 is the most popular. But it is more like making your CPU run a decathlon, so it really does not stress real world performance. Your CPU will never be worked so hard in the real world as it does in Prime 95. So I don't use it.

    I use Intel Extreme Tuning Utility (XTU), but I don't think that will work on an AMD chip. But it may be worth a try.

    CPUz also has a stress test. It is not too demanding, but it is free.

    Aida64 is popular, but I don't know if it is free.

    You can just run CinebenchR15 benchmark a few times to monitor your temps.

    If you run a few benchmarks and you temps are okay, then you can always just game and see if it crashes. Just don't get mad if it crashes at a bad time.

    When your system crashes, don't panic, just go back in the bios and either add more voltage or drop your frequency.

  6. What would work better to change? CPU frequency or CPU Multiplier? Should i change the CPU-NB voltage or leave it as it is on auto?

  7. Like I said, I am not familiar with AsRock Bios, so I don't want to lead you the wrong way.

    The frequency and the multiplier are the same thing. What you don't want to change is the BLCK. The BLCK should be at 100. Leave it there as the math will get funny if you change it and it also changes the clock speed of the memory (but I wont get into that). If you want a 4.4ghz OC, then you would change the multiplier to 44. 100 (BLCK) x 44 (multiplier) = 4400mhz frequency. 4400mhz = 4.4ghz. The 4.4ghz will be your frequency.

    Jayztwocents is a youtube guy and he has some excellent videos on overclocking. This one is on the 8350 and will help you out.

    His video may use a different board and the bios may not be the same. So if you still have problems, google AsRock 990FX Extreme 4 Overclocking and go to the videos. There will be a gazillion videos walking you through the process of your board.

  8. He has got a lot more options in his BIOS, so far running 4.4GHz at 1.425V and it's stable, thank you for your help.

    What are your temps at 1.425?
