Is my CPU throttling?

[4b33r]

Hello,

Greetings,

So I just overclocked my FX-6300 to 4.1 GHZ at 1.4 volts.I burn tested it to check the max temps and it is 63,pretty good according to me but then I noticed something,as soon as I set my temprature polling rate to 100 miliseconds something weird happened.My clock speed flickered at random times on random cores.I thought is my CPU throttling?I mean it's only 63 celcius max and throttling at that would be impossible.

Here is a clip of what happened - https://www.youtube.com/watch?v=2x5_PpLgHIU&feature=youtu.be

Thank you.

I don't think so, it's just the temp monitor being weird. Try setting the polling rate up a tad, you don't need to refresh it so often

@4b33r  It looks like cool'n'quiet might be adjusting the multiplier to me, which I dont thing it should be doing when at full load. At the temps you are at while testing, you shouldn't be running into a throttling problem. I know I haven't hit thermal throttling on my FX-4300 chip at those temps and above back before I got my H75 AIO cooler. 

What motherboard are you using by the way?

Gigabyte 78 lmt usb3

@4b33r  Oh, that motherboard. The chipset on that motherboard (760G chipset to be precise) wasn't designed to run the bulldozer and piledriver FX cpu's. It has just been bolted on after the fact. The chipset was released around 2007/08, and the current FX chips where released in 2011 for bulldozer, and 2012 for piledriver. I would say your motherboard could potentially be holding you back with a 6 core CPU for the purpose of overclocking.

[4b33r]

But it isn't throttling right?

So should I continue overclocking?

@4b33r  I wouldn't suggest overclocking further on that particular motherboard, as I think you will overstress it and burn it out; which could potentially take out other components connected to it. As far as I can see though it isnt trottling, but there could be an issue with you socket or northbridge temps. Or even the VRM's overheating. You would need something like Hwinfo or HWmonitor to check that aspect though, and would also depend on how you went about overclocking. By that I mean either FSB or multiplier  to increase the CPU clock speed, or a combination of both.

[4b33r]

multiplier only oc.

and I do have hardware monitor but no mobo temps show up in that.

[Ialyrn]

Could you post up a pic of your temps from HWmonitor while your system is under load and while at idle.

[4b33r]

sure,also the thing is,my cpu core voltage in hardware monitor and core temp is 1.2 volts max.But in my BIOS it's 1.4.

[Ialyrn]

Use CPU-z for monitoring core voltage, as it will show almost identical to what is set in the Bios in most cases.

[4b33r]

even CPU-Z says my voltage is 1.2.

@4b33r  TMpin2 seems fairly high, and I am having a hard time finding out which temp sensor that is on your particular motherboard. Hopefully someone else will jump in with more information on that aspect. I keep finding contradictory answers on that. Some say it is the CPU temp, others say it is the socket temp, and others say it is the northbridge temp, and it just goes on like that.

I would suggest taking the side panel on the right of your case, and check the back of the motherboard socket while your system is under load.

As for CPU-z, I have no idea. Are you certain you have the voltage on manual and not auto?

[4b33r]

I already have removed my side panel.

And yes I am sure my voltage is on manual .
