Super hot FX-8350

Hi experienced AMD overclockers!

I'm an overclocking newb who's trying to get a FX-8350 to 4.6 or 4.8 GHz on an ASUS mobo with a Cooler Master Geminii S524 cooler. Can somebody give me an idea of what i'm doing wrong?

My temps @ 4.8 GHz with 1.44 vcore is 46 degrees idle, it crashes at load temps. Is my cooler not good enough or something? I have no idea why my CPU is so hot especially at idle temps. I'd expect something like that more from a stock cooler.

Yes, i disabled Cool'n'quiet and all the power saving modes, including C1E state which i heard could cause voltage swings. Yet I don't know why my temps are so hot. Should i just settle for a 4.6 GHz overclock? Do you think my cooler could handle that?

Thanks!

Ouch, 46*C on idle?
Are you sure it is installed correctly?
Not too much voltage on the CPU?

It's louder than the stock cooler :ouch: 
But it should cool a little better than that-but you may need arctic 5 or TX-4 thermal paste. But if you hit your thermal limit-then you've hit your thermal limit.

I have not used that cooler but my best guess is you are trying to push that CPU to far. I have a FX-8350 based rig and have found that it work just great with just a multiplyer overclock and I have not even touched the voltage what so ever and never will as I do not think it is needed for that CPU. However if you are really wanting to push it that far you should look into water cooling because I am not sure a air cooler is going to get you want you want without burning up that CPU.

yeah, like I said, it's just 1.44 vcore voltage.

I'm pretty sure my CPU is installed fine because it idles more at like 25 degrees before I overclocked it. Idk what's wrong, i did all the stability things that people recommend for ASUS mobos and i don't think 1.44 vcore is to much. I looked at a guide on the ASUS ROG site and they said to increase the vcore all the way to 1.5v but i was a little scared to do that, and i'm already getting ridiculously high temps on 1.44v.

that isn't a great cooler, but it isn't bad either. Sounds like you have too much or too little thermal paste... clean both the sink and cpu and reapply with some solid thermal paste like artic silver 5... a pea drop in the middle of the cpu, press down gently, secure your sink. take it off and check the spread of the thermal paste. it should be spread out like a circle covering most of the heatsink, nearly to the edges. if it isn't you used the wrong amount. clean it and try again or if you got it right apply the same amount. trial and error till you get it right, then clean it and apply what you used the right time, and button it up and try again. know temps will probably come down over the course of 24 hours as the paste "sets"

1.45 is the lower range of a max vcore you want on a 8350. if you have an asus motherboard turn on LLC, it should let you stabilize the overclock at a slightly lower vcore. Understand if you can't bring temps down you'll either need a better cpu cooler (and there are cpu coolers that should get you 5c-7c improvement at load temps) or better case air circulation (lower ambient temps will lower cpu temps)

This ^^. But if you go with TX-4, the application is different. (It comes with instructions)
And if you increase bus frequency, then you'll most likely need more voltage, if you're increasing the multiplier alone-then you should be fine up to about 4.5-4.6. But every chip overclocks differently.

generally the fx8350 will clock up to 4.2-4.5 on stock vcore... you shouldn't be adding vcore unless you NEED to. just because you bumped the multiplier up to 4.8, doesn't mean you HAVE to add vcore. If you're just stuffing vcore into the cpu you're not doing the cpu or yourself any favors. that's not how you overclock.

thanks ingtar33, i'll try lowering the vcore a bit. I'm pretty sure the thermal paste was ok the first time around cuz my idle temps unoverclocked was about 25-27 degrees.

I always thought that you needed more vcore to make an overclock stable, but I guess it's trial and error with stress tests :) .

yep, it's trial and error. how i do it (which is how you should do it), is i keep the vcore on stock (i think its 1.33850V it might be 1.35000V, either or, doesn't matter), and bump the cpu multiplier up +0.5. save and exit the bios, see if your system will load into windows. If it does, jump into your bios again and bump the multiplier again. I keep doing this till it won't load into windows or POST. Don't worry if it won't post you can fail to post 3 times and most bios will simply reset to stock and it will load on the 4th attempt. If it doesn't you just clr_cmos and start again.

This is when you first start to add vcore. Only add it in the smallest increment the board will let you use (typically 0.01250V). just by a +0.0125V, save, restart, see if you'll load into windows. rince and repeate. Once you're in windows you'll try a short prime95 run. just 2 or 3 passes. as long as it doesn't crash the system, or a core fails you can resume to add cpu multiplier.

keep adding multiplier till it fails to load into windows or you reach your desired overclock. Then you attempt to stabilize for prime with small vcore bumps.

EVERY cpu is different. some will stabilize easily at 4.8ghz with only a little more then stock vcore (1.4V)... some will still be on stock vcore, yet others will turn into mini-suns at 1.55 vcore, while others won't do it for all the power in the world. it depends on if you won the cpu lottery or not.
