Vcore FX 8120 Stock

[wanautentico]

Hello everyone, I recently assembled an FX 8120 on an Asrock 980 DE3/U3S3 motherboard.

This micro has a frequency of 3100 Mhz and with turbo core to 3400 and with less than 4 cores to 4000 mhz.

I started to have some temperature problems with a Scythe Katana 4 which I saw up to 67 degrees.
And no matter how much good thermal paste I put on, adding fans to the case, it didn't solve the problem...

So I looked at the voltage that the Asrock was putting on the micro because I didn't see it as normal and I think it applies a fairly high value, 1.416 v.

I manually set it to 1.38 and the system is stable and the temperatures improved.
But I wanted to know how much more I can lower it, that is, what is the stock vcore for the FX 8120.

Because I think that the manufacturers of motherboards automatically put a fairly high vcore to ensure the stability of the system.

Thanks and goodbye.;D

Hello, everything is in testing.

I tell you my experience with an athlon x4 620. I have managed to put it at 0,7v@700 mhz and at full without oc it is at 1,1v@2600 mhz and the temps are noticeable a lot. Try pscheck and k10stat (I don't know if they work with fx) and adjust vcores with vid and multi to do undervolt in conditions.

Best regards

So check with the stock cooler what temperatures you have because it's not normal since your CPU runs stock at 1.425V... your motherboard undervolts to 1.416v, which is normal by the way.

That said, check how it behaves with the stock cooler with everything on auto and a bit of heat with OCCT or with AIDA64 in FPU mode (I recommend OCCT because it creates a folder where it logs/graphs the parameters of everything it has recorded)

And you send us some screenshots ;D

As for lowering the voltage... the same, if you want to undervolt make sure that OCCT is stable for you.

Regarding the Scythe Katana 4 I think it's a bit weak for a micro with a TDP of 125W, probably better than the stock (I don't know how much better) but in any case insufficient to calm the wrath of an FX.

Anyway you shouldn't worry about it getting to 67º, if the micro handles it well and doesn't do "Thermal-Throttling" then nothing happens... the problem is if it drops below MHz because you will lose performance but don't worry the CPU won't burn... unless you have disabled it in the Bios
