Temps too high with little OC

Hello friends,

Here is my build:

High Power Performance 600W
AMD FX 8350
Noctua NH-U14S CPU Cooler
ASUS M5A99X EVO R2.0
Kingston HyperX 4x2GB DDR3 1600 DIMMs
Sapphire R9 290X
Corsair Force GS 128GB
Corsair Carbide 400R Chasis

With everything stock and DIGI+ Power Control settings default (everything at regular etc.) I get 20-25c of idle temp and 40-45c full load (with prime). Now everything is fine here.

Check the screenshots please:

But if I set the CPU Load Line Calibration to Ultra High and CPU Current Capability to 130% without increasing the voltage and the frequency I get this:

As you can see with these two settings the temps are already high enough. So if I try to push it to 4400 mhz with stock voltage I get about 59c already and I cannot even try to push further because the moment I increase the voltage it gets about 65 and I don't even mention the socket temp which you can see in the screenshot. I am already at limits.

What do you think I can do to push? I noticed that CPU runs at 1284v when the LLC and Current Capability settings are default. But I don't really know...

First, is this temp normal? (I don't think it is yet still...) Secondly, is there anything I can do to improve the situation in terms of overclocking and temps?

Thank you in advance.

I have the same mobo with the same settings altough i use the bios for Digi+ power control settings. i have a fx 6350 oc to 4.7ghz with the load line at ultra high and cpu current at 130% with a noctua NH-U9B and my idle temps stay at around 30c and under load gaming it never gets over 45c in prime 95 after about an hour it will hit 60c and pretty much stay there. 60C is fine as long as it never goes past 62c your good. 69C not so much what psu do u have it might not be able to handle those settings.

Welcome to my world.

Alright I'll start things off. No, those aren't worrysome temps, the max safe temp for this chip and indeed most AMD CPUs is 62c.
At 70c it will begin throttling and 80c will probably cause it to shut down.

The CPU LLC (Load Line Calibration) is essentially setting the board to compensate for voltage loss under normal and load conditions. This is known as:

Vdrop = The slight decrease in volts versus what you have manually set in the BIOS under NORMAL conditions.

Vdroop = The even further decrease in volts when under FULL LOAD conditions.

What the LLC does is attempts to try its best to correct this, the problem is that it's not perfect, you can either have it undershoot by as little as possible, or overshoot by as little as possible. Personally, I prefer to overshoot for stability sakes. Ultra High is the setting I use as High causes the undershoot.

When you think that undershooting the voltage when you've upped the multi yet still remain on stock volts, it's going to run in to stability problems.
Increasing voltage is what increases temperatures with an overclock, so even minor steppings can cause quite the change. Your temps are looking pretty much on par with mine given the same kind of overclock and same kind of settings.

Of course, every chip is different. Some can pump major voltage without getting hot at all, some boil under minor increases (That'll be mine then). It's a binning lottery.
Some chips can go really far on just little increments of volts, those are the golden ones.

You would be safer to keep it on its current LLC setting and OC, having a few degrees of headroom from the limit is always a good idea.
Your 1.38 under load volts matches the same as mine exactly. Awesomesauce.

Finally, don't worry about the socket temp so much. I know there's a limit but it's more of a guideline. It has nearly nothing to do with the CPU, it's a sensor under the socket. It's usually about 10c higher than the core.
Also, your power supply has a bit of a generic name for that kind of build.... doesn't it? Is it a cheap one?


It was most likely throttling before to get below the stock volts of 1.365 under load.

Well, PSU is a bit old compared to the system but I'm thinking of changing it with a good 750W. Do you think It might have an effect on overclock?

Also thank you for all that information I now understand what LLC does. I will keep it on Ultra High with 130% capability. But something bugs me. Will I not be able to push more than 4400? I was hoping to see 4.7 at least.

It probably won't help all that much, but a quality power supply is always a must.
Aside from just being able to power the system, the only real effect a decent one will have is delivering cleaner power through the VRMs, enhancing longevity somewhat because there's not a whole chunk of ripple going on.
That and efficiency of course. The more you spend the better you get.

And yup. I was aiming for at least 4.6 with mine. Things just got too damn hot so I'm stuck with this.
I suppose if you're adventurous enough you could try FSB overclocking. I don't think you'll get huge frequency gains though.

Well, I guess knowing I am not alone is enough. I will try to push a little bit for 4.5 and that's all.
