The GA-M68MT-S2 (rev. 3.1) lists the FX-8120 (95W) as being supported. In fact all FX processors listed as compatible for the motherboard are the 95 watt TDP (Thermal Design Power) models. The 125 watt TDP models are not supported. There are two FX-8120 models, one is 95 watt TDP and one is 125 watt TDP. I believe only the 125 watt FX-8120 was sold in the United States.

Thanks for the quick response. I know for a fact that I have the AMD feature "Cool n' Quiet" enabled on my CPU, but would the downclocked speed appear in the system information section on Windows?

So I found something interesting, it seems that my motherboard only supports the 95w version of my CPU. Although, I was under the impression that the 8120 only came in 125w? Can someone clarify this for me?

Well considering my PC was originally a pre-built rig, (I know, huge mistake) I'm not sure which variant of the 8120 I'm currently using. The PC was sold to me with the assurance that the 8120 was clocked to 3.1ghz.

Ok, so I downloaded CPUID, and my max TDP is listed as 124w. Is that strange?

The Thermal Design Power (TDP) of 125 watts is the average maximum power a processor can dissipate while running commercially available software. TDP is primarily used as a guideline for manufacturers of thermal solutions. Your motherboard was not designed to use FX CPU's with a TDP higher than 95 watts. Too much thermal heat can lead to premature failure of the motherboard.

There are several low-power state items in the BIOS options.

FX-8350
Low power P states (they can vary slightly)
#1: 3400 MHz, 1.225V
#2: 2800 MHz, 1.125V
#3: 2100 MHz, 1V
#4: 1400 MHz, 0.875V

FX-8120
#1: 2800 MHz, 1.1375V
#2: 2300 MHz, 1.0625V
#3: 1900 MHz, 0.975V
#4: 1400 MHz, 0.8875V

Ok, so I think it's safe to say that my motherboard is only compatible with 95w cpu's. With that said, would you recommend buying a motherboard that supports 125w, and therefore will use my cpu to its full potential?
