Trying to overclock AMD FX-4100 Quad-Core 3.6 GHz

I tried overclocking my processor last night with not much success in the end. I overclocked it to 4.2 GHz and my computer didn't seem to be working propperly. Whenever I would run a game, for example Minecraft. The game would just jitter around and it feels like the game speed has been turned up to 2x. Is there something else I need to overclock in order to get my CPU not lag around so much? I used the AMD Vision Engine Control Center, by the way.

  1. I would advise over clocking through the BIOS. But I have only managed to get 4.1GHz out of my FX-4100 stable. Have you ran any stress tests? I reccomend Prime95. If you get any illegal sumouts then drop down the mulitplyer.
  2. Are you using an aftermarket cooler?

    Unfortunately no as I can't find one that doesn't obstruct my RAM, and is short enough for my case. However people have gotten 4.6GHz out of it using stock cooler and voltage. Also my temps are currently fine at a max of 51'c during a Prime95 load. I suggest to him to underclock it to 4.1GHz and see if it is stable. But the motherboard could be throttling due to mosfets overheating, or because he hasn't disabled AMD's power management crap.
  4. Thanks, I think my mosfets are overheating so my motherboard is throttling.. also my motherboard my have a crap VRM... my motherboard is a GA-990FXA-D3
  5. I noticed my chip was very finiky to which mixture of OC I performed... some said crank the multiplier and some said crank the clock. For a 4.51 Ghz stable on this I had to go 205 clock with a 22 multiplier and 1.43 cpu volts. Both 23X and/or over 205 would lead to 4.6Ghz which wouldn't pass all the testing... Very finiky
