Need beginner advice on overclocking.

Hi,

I recently started overclocking my AMD fx-8350 (with heatsink cooler master hyper 212 evo). Under full 100% load stress testing using prime95, I was able to overclock it to 4.3Ghz and maintain a constant temperature of 65C, nothing higher, sometimes dipping down to 64C.

Note: I did not change the multiplier and left it at a default 20.0, and changed the bus speed to 215Mhz.

This is actually a follow-up question to my previous post: http://www.tomshardware.com/answers/id-3232338/gtx-1070-preforming-forza-horizon.html

My question is, because the games I play never use 100% utilization (on average, 50%) of my cpu, would it be wise to crank up the Ghz to 4.5 or 4.6? In cases where It does use 100% of my cpu, it never lasts more than a second and the temperature would only rise during then, then fall back.

Thanks.

  1. No that's not beneficial. If the game wants more speed it's going to up your CPU load either way. So at 4.5ghz lets say your at 50% usage, at 4.6ghz it's going to lower to 47% (as an example).

    Plus add in that it won't be stable enough for 100% usage.

    For gaming in my case, what would you suggest to get better single-threaded performance? As explained in the discussion in the previous post, that guy with an i5 is getting a crazy 20fps more than I am. What would I need to tune to gain more fps?

    The best way is to overclock in a different manner, something that not a lot of people actually do. That is by a core by core basis.

    If you set up your core multipliers like this (as an example): 47, 47, 46, 45, 44, 44, 44, 44 you'll get more performance since only the cores that the games will be used will be loaded up and thus run at a higher clock speed. Similar to how Intel's Turbo Boost operates.

    Side question:

    I did a little looking into core by core overclocking, and turns out, that's similar to what AMD turbo core boost does. Would you recommend using that option, or overclocking manually? Also if I do overclocking manually, should I turn down my current overclock settings to factory defaults (like bus speeds down to 200)?
  5. Do you mean overclock the turbo core instead of the main clock itself? If so, uh I'm not sure. I've never overclocked an AMD CPU before.

    You'll probably want to go to default bus speeds at least until you find your max overclock.
