Please help, new to computer building - AMD Fx-9590 running at 1.4 ghz, x 7.0 multiplier, .856 V. Huge FPS drops when gaming.

Hello, if anybody could take the time to help me, I would VERY MUCH appreciate it, I'm getting extremely frustrated.

I spent a lot of money building my first gaming PC. I built it last April, and I've always had FPS issues when gaming from day 1, but I recently started streaming and it has gotten way worse, to the point where it's nearly unbearable - 15-20 FPS.

I downloaded CPU-Z, and here is what my AMD FX-9590 4.7ghz CPU is doing:

Core voltage: .856 V
Core Speed: 1399.92 Mhz
Multiplier: x 7.0 ( 7 - 25)

My other specs are:
Motherboard: MSI 990FXA Gaming
GPU: NVIDIA GeForce GTX 1070
RAM: 32 GB DDR3
PSU: EVGA SuperNOVA 850 G2 220-G2-0850-XR 80+ GOLD 850W
Cooling: CoolerMaster heat sink
Samsung SSD 850 EVO 500GB
I have an Asus 144 hz monitor.
I am using Windows 10.

I have been running MSI Afterburner while gaming. My GPU never goes above 70-80% usage, but my CPU cores always spike up to 100%. After running CPU Z and seeing how low of ghz my CPU is running at, I realize that's obviously the cause of my huge FPS drops in game despite the expensive GPU.

MSI Afterburner has consistently informed me that my CPU core temp ranges from 1 to 4 degrees celsius. CAM monitoring software says the current CPU temperature is 3 degrees celsius. The case came with two fans, the GPU has two fans, and there is a fan on my heat sink. The CPU has never gotten remotely hot, likely because it isn't doing it's job. -______-

I tried finding the "slow mode" power switch on the board. Rebooted - CPU still sat at 1400 mhz, though I wasn't trying to run any games.

Any ideas what is causing this? Any help is VERY much appreciated

Lower CPU multiplier to some 4.6 - 4.7 GHz and it will most probably work better, like this it's running out of power under high loads.

What does AMD Overdrive say about temperatures? Note that it'll give you the thermal margin, not the temperature. First, monitoring software tends to be quite poor at reporting the temperature of FX chips and the temperatures you're getting from the software you're using is impossible unless you're using your PC outside at below-freezing temperatures. Second, if you have a large heat sink with "a" fan at all, you're using an inappropriate cooling solution for a 9590, a mess of a CPU that shouldn't even be run without something on the level of an h100i or better.

Thank you very much for your response. I did not realize the other monitoring programs recorded inaccurate temperatures of FX chips. I downloaded AMD OverDrive - the thermal margin of each core is at 69.8 - 70.0 degrees Celsius.

UPDATE:
Went into BIOS, disabled "CPU Smart Mode" and lowered the frequency from 200 x 23.5 to 190 x 23.5 (wouldn't let me lower the multiplier). Now this is my reading:

Voltage seems...high...and the thermal margin fluctuates from 40-55.

You're definitely getting some odd readings - those temperatures *still* don't make sense. Unless you're using exotic cooling like nitrogen or Peltier cooling, your CPU can't be below room temperature. A lot of FX chips that don't cooperate temperature-reporting wise at idle look more normal at load, but at load with a non-recommended cooling solution, I'd expect you to be somewhere around 70.

That's the stock voltage. I'm suspecting something physically wrong with one of the components, it's more than just getting the temperatures reported incorrectly. How is the *performance* when you underclock? I'd dial the multiplier down to 20 and the voltage to 1.375 to try to get this running like an 8350 first (a 9590 is essentially a binned 8350 that has had the bejesus clocked out of it).

Unfortunately in the MSI Bios it doesn't appear that I can change the multiplier, only the frequency. It won't even let me lower the frequency below 190, with the multiplier still on 23.5, and when I try to do the OC Genie, it says that Genie doesn't work with CPUs above 200W.

However, I've been running a video game for the past two hours, along with spotify, discord, and google chrome. Here are my current readings:

Either way I am planning on purchasing a liquid cooling system. Any recommendations? I'm looking at the H80i or the H80GT right now based on a friend's suggestions.
