overclocking fx 8300

Hi guys
Just oced my fx 8300 to 4ghz after tuning the voltages (1.260v on cpuz dont know if it is correct)
i stressed test it with furmark's cpu burner with max temp 70celcius and while idle it reaches 40 celcius.My question is if the 70C are too hot for my cpu under full load.
my mobo is the asus m5a97 r2.0 and i have an artic cooler freezer 7 pro rev 2 for cooling
also my case has a great air flow and the abient temps are 24-28C

  1. Yes that is too hot and in gaming it will start thermal throttling. Two reasons

    1. That cooler sucks, Arctic generally is low end junk

    2. Your motherboard isn't so great either and has a poor VRM setup.

    If you want to continue to do this the CPU needs a little more voltage and you need to keep those max temps around 65 to prevent thermal throttling. Its still a bad idea with that setup

    well at gaming it reaches 58C (tested it with bf1 60-70%ingame usage) and i stressed test it again and max temps were at 65-66C with furmark at 100% load for 30 min
  3. If it stays at 58 while gaming you're good no thermal throttling.

    If your temps stay around there you are fine. I don't know how long that motherboard will be able to keep up with that (a few months?) But its working now.

    Do you mean that my mobo will fail?If i upgrade my cooling will it be the same for mobo and cpu?
  5. Basically as I said that motherboard has a weak vrm setup. Right now everything is fine and it may well be fine for a while. I would not overclock further and I would also not be surprised if, over time it started to lose stability. May take some time though.

    underclock it to 3.9ghz with auto voltage (its boost is 3.8) i dont think that there will be any problem
    also i wont push it to 4 ghz again because yyou scared m a litttle about my mobo :P

    That would be fine as well.

    Basically you got lucky as usually those small VRM motherboards are poor overclockers. So while it works, I just dont see it lasting.

    what do u mean smal vrm? my mobo has a heatsink on the chips around the cpu
  9. The VRMS on that board are only 4+1, for an overclocking system you want 8+2. So its small, half the size of what you want.
  10. Hi again i oced it to 4gz stable this time! With max temp of 63oC under full load.vcore under load is 1.176v and for a strange reason at idle its 1.212-1.264V.Will it be ok now?

    63 is right at the point its going to overheat and throttle. I would back off.

    Question from tryf : "Ocing Fx 8300"

    hi all!!
    i oced my fx 8300 to 4.2 ghz.In order to test its stability i used cynebench and furmark cpu burner at the same time. also i run furmark for 20 min with browser and other programms on the background just to check for any instability.Well there were none But when i join servers on bf1 i get bluescreen.How is that even possible?1 stress test and 1 benchmark running simultaneously
    and it crashes ingame..

    Cpu:amd fx 8300
    Frequency: 4200
    ref*multi: 200*21
    CPU voltage: 1.224 at vdrop full load 1.284 at idle
    RAM: 2x4gb ram 1866ghz
    Motherboard:asus m5a97 r2.0
    Cooling: artic freezer pro rev 2.0
    psu:cm 550w semi-modular 80+ bronze
    OS: win 10 64 bit
  13. As you mentioned before, its overheating 63 is too much, and/or the VRMs are overheating like I discussed with you. Gaming loads can be different than software loads. Your cooler can't keep up (its not a good one) and your VRMs are too small and weak and have no cooling. Time to back down that overclock it is FAR to aggressive for that motherboard.

    well at 4.2 i get max 68oC
    my vrams have heatsinks its the non le model
    i have a decent air flow inside the case and i want to leave it at 4 ghz at least its only 0.2 ghz oc from its stock boost 3.8ghz i dont think that 0.2gzh oc with a minium bump on the voltage will hurt my mobo or cpu that much
    and about the cooling i am thinking buying the corsair h55 liquid cooler but is it even worth it?
  15. Best answer
    Yes 200 mhz absolutely could make the difference. And heatsinks on the VRMs doesn't make up for the fact there are half as many as an 8 core FX processor needs for stable high level overclocking. And 68 is even worse thats thermal throttling level of heat.

    A H55 is a waste of money you are still limited by the motherboard, if you're hell bent on overclocking this thing further you need a better board.

    Its not about hurting anything, its about the CPU throttling due to its own heat or VRM temps and it slowing down and choking your games. Or crashing as you have already seen.

    hmm i get it! I will let it be at its 3.8ghz boost.Buying a new mobo is a waste of money at the moment i will save up money to update to a ryzen 1600x when it releases any recommended am4 mobo that will get me throw a mediocore oc?
  17. Most AM4 boards are set up for overclocking. I have the Crosshair VI Hero but its very expensive. The ASUS PRIME board would be fine, but keep in mind Ryzen CPUs do not have a lot of headroom for overclocking. You'll get 4 maybe 4.1 ghz tops.

    Of course even stock its worlds faster than the FX-8300
  18. And the last one any good water cooler? At 120mm only :P

    120mm water coolers are a waste of money, a good air cooler will perform just as well. You need a 240 or 280 for it to be worth it.
