AMD FX-8350 overclock with ASRock 990FX Fatal1ty Killer - Page 3

post #21 of 32
The ASUS Aura is a better board than the UD3P and is the one to recommend, although it costs more.

No LLC is not a problem on well engineered boards like the MSI GD80.

Here are the screenshots of my board settings:




Temperatures and voltages while stressing with OCCT 4.4.2:


vcore is at 1.41v at idle, drooping to 1.34v at load



And as you can see, after reaching that certain temperature it starts to throttle, dropping to 1400mhz and coming back to 4400mhz, to maintain the temperature I suppose...

So yes, my question was if I pass the stress test even tho it is throttling in this spikes, and I think I will never butcher my CPU like OCCT does, not being always at full speed while stressing can't guarantee me that is stable, right?...

I read everything and saw all you posted, but unfortunately my case doesn't have much room for modding (sorry for the bad quality on the photos):








Tried my best with the cable management, I don't think I missed something in this post.
I'll see to the fans blowing onto the VRM when I can.

Thanks all!!! smile.gif

For starters change the following settings in your BIOS...

Under main tab:
Spread spectrum = Disabled
Turbo = Disabled
AMP = Disabled
AMD APM = Disabled

Under Advanced tab:

CnQ = Disabled
SVM = Disabled (unless you use virtual machines)
C1E = Disabled
Core 6 Mode = Disabled


It is possible you are not thermal throttling at all, but simply experiencing the power saving features you still have enabled in your BIOS. By disabling the above settings you will literally lock you CPU to run 4.4Ghz, 24/7, 365. That is what you want when you are assessing an overclock or doing any stress testing. If you still see throttling then it is indeed likely the motherboard cannot handle your current thermal situation, and you need more cooling to proceed.

I have another idea that may give you some head room on thermals, by lowering certain voltage settings i see; but try this first and report back here. If it works then you know it was just the power saving features messing with your set up. You can always re-enable them in the future if you really want and care about such things...but during bench testing and stress testing its best to disable them for stability and accuracy of readings sake.

I personally also disable my thermal throttling on my board, but i have very high end cooling solutions and monitor my temps extremely carefully. Doing so comes with some level or risk, but its one i am willing to take to push my machine. I also have a back up FX-6300 platform if i blow **** up to get me by till i can replace it.


Good luck, ill keep my eye on this thread to help more if i can. thumb.gif

Sorry for the lack of updates, hadn't had much time nor patience...
Well I can't quite risk blowing my FX 8350 guiltysmiley.gif but I deactivated all on the cpu side settings of the UEFI, even the auto thermal throttle, and it kept going, but was on the ~92ºC on the socket/cputin, and ~64ºC on the package, and it gave an error on the core #0 after ~10minutes, so maybe more voltage, or the temperature is causing the instability.

By the way, what software would you guys recommend to test overclock? I've seen so much different opinions and programs that I'm inclined to start using ASUS RealBench, always used OCCT but the new 4.5.0 version seems buggy, so I stick with version 4.4.2. I even use OCCT to test gpu overclock, but again, maybe there is a better or recommended different approach for that. Sorry for this off-topic, I'm curious, and confused... tongue.gif

IBT AVX, check the Vishera thread.

I can run my 8350 @ 4.7 with my 78LMT-USB3, I'm sure with proper cooling you can do better smile.gif

I use version 27.9 (i think) of Prime 95 as it was the last version optimized for AMD. Newer ones cause errors due to optimization issues.

Those are indeed temp limits if accurate and most likely are your issue. You need to back it down in clock and voltage and/or find better cooling.

What if it doesn't start to throttle and temps continue to climb? Will it protect itself by shutting down or something? Or should I just not even risk it? Because I would really like to overclock it, but not damaged it, and deactivating all on the CPU UEFI settings, like "CPU Thermal Throttle", seemed to stopped some of the throttle, but I did not had time to test further, so this is just some curiosity and safeguarding questions. tongue.gif

64C on the package is the cpu?

92C on the socket?

That sounds like the cpu is ok but the motherboard is burning up. This is typical of Asrock motherboards. You need to get a fan on the back side of the motherboard in the cpu socket and vrm area in order to cool it down.

That is impossible for me right now, my case has no room for a fan in the back, and I don't feel very comfortable with messing with modding this case... frown.gif
And I almost don't have space on the VRM area because of my cooler

Your circumstance is limiting your potential. Back things off to reasonable levels and be happy with what you can get until you can improve your cooling soultion.

Running Asrock AM3+ boards too hot is the number one cause of their failure and the reason they have such a sketchy reputation and mixed reviews.

Keep your thermals and voltages under control and you can have great performance for years to come.

The ability to overclock is directly related to your cooling capability more than any other factor with FX setups. If its truely something you want to explore invest in a better case and cooling solutions.
