AMD FX 8320 Overclock Question

I have decided to OC my CPU to 4.0 Ghz from 3.5 Ghz. I have never done any kind of OC-ing, so I am a complete noob in this field. I have read that I can simply go into BIOS and from there set the multiplier to 20. I have done that, but I have set it to 18.5 (3.7 Ghz) because I am using the stock cooler. I am waiting for my new cooler (Hyper 212 Evo) so when the new one arrives I will set the multiplier to 20 (4.0 Ghz). After doing that, I ran the CPU-Z program and there I noticed that my Core Speed has been jumping all over the place. Going from 1.4 Ghz all the way to 4.0 Ghz. I have disabled Turbo Mode in BIOS and I have also disabled CoolAndQuiet mode in BIOS. Is that normal? When im stress testing then my Core Speed sticks only at 3.7 Ghz. So my question is, have I done everything right? Is that normal what is happening?

Also, here is my rig: GPU - Palit GeForce GTX 670
CPU - obviously AMD FX 8320
RAM - Kingston KHX2400C11D3/4GX (2x4GB)
Motherboard - GIGABYTE GA-990XA-UD3
Motherboard Chipset - AMD 990X (RD980) + SB920/SB950
BIOS - F12
OS - Windows 10 Professional 64 Bit

On the side note one more question regarding my RAM. I have 8 GB of RAM. When I check my RAM info in the program HWiNFO, it says that the Maximum Clock is 1200 Mhz, but in the actual state of the RAM, it says: "Clock - 671.1 Mhz = 3.33 x 201.3 Mhz", "Mode - Dual Channel", "Timing - 9-9-9-24, tRC 33". Does this mean that my current RAM is clocked at 671.1 Mhz? If that is true then that is very bad/low and that shouldn't be normal, am I right? Can anyone help me regarding this issue and where to set it to "normal" state/clock.

I apologize for maybe asking dumb questions but as I said I am really new to all of this and require assistance. Thanks in advance!

Did the new cooler arrived in your hands already?
If so, did you make sure before installing the new cooler, you cleaned the TIM (thermal paste) and applied a new spread and applied enough pressure on the metal bracket?

For the motherboard settings, I am abit less knowledgeable on Gigabyte boards because I've been mainly operating on MSI and ASUS but usually, to test the overclock stability, run something like Cinebench, or AIDA64 for 10 minutes. Observe the core speeds via Core Temp. For 4Ghz overclocks, you gotta bump the voltage to 1.32V to be on the safe side. If lucky, you might get away with just 1.28-1.29V!

You need to disable some power saving features too such as SVM, Core C6 state, HPM.

For the RAM part, I believe your RAM is running at default 1333Mhz due to some reset in BIOS, so try activating the XMP profile for it here: M.I.T.\Advanced Frequency Settings menu, and select the 2400mhz profile.
