Ok mjw21a.
And how i can set the board Asus M5A97-Pro to automatically overclock 8120 to hit 4ghz wid no worries?? = There are always concerns and considerations. However the design of the FX-8120 you are asking about is designed by itself to clock up to 4.0Ghz if the load on the cpu is registered in a certain way. More about that below.
And If AMD FX 8120 is comfortable for all type of heavy gaming and multitasking works??as i dnt have budget to buy intel 2500K,so going for FX8120.. = I might even drop back to a less power consuming FX-6100. We have had a few people come to the forum from India lately and the temps in the room where their computer is used, is very high when compared to other places people might live. A 'hot' room for the computer, means that it will be hard to keep things inside a computer case really cool overall since the air outside the computer case is already 'hot'.
FX-8120 AMD designed speeds with inbuilt Turbo Core Control.
Base CPU Frequency = 3100 MHz
Turbo Core frequency = 3400 MHz (8 cores)
Turbo Core frequency Max = 4000 MHz (4 cores)
In situations where you’re running an application that doesn’t tax the processor’s resources, Turbo Core dithers between the processor’s base frequency and a higher clock rate, jumping between them to average better overall performance at the defined TDP.
When you look closely at the specs for an FX processor and see CPU Base, CPU Turbo Core, And CPU Max. Turbo, you are guaranteed to always get at least that base cpu frequency to do work. You’ll see the Turbo Core clock rate so long as TDP is in check (as it would be in a well-threaded workload that doesn’t exceed the processor’s TDP ceiling). And IF half of the chip’s cores are idle (not doing work), it’s possible to realize maximum Turbo Core speeds.
Now that is how AMD designed the newer FX-series of processors to work. When the processors are used as designed they are THEN power efficient and the CPU temperatures do not rise so dramatically as many find when they "use" the words, I want to overclock my FX-series processor.
I don't know if you have come to grips with what is written above or not. If you have then here is what you are advised to do normally when you say you want to overclock your CPU.
1. You are advised to disable all the green control items so that the cpu cannot throttle down when not loaded. This is pretty power consumptive. The system is forced to run at a hotter, high rate of speed all the time.
2. After turning off all the power/electricity saving modes then most of the time you would raise the speed of the cpu beyond its designed speed and this means you add more voltage to the processor circuit to alllow for faster than normal cpu speeds. This adds more heat.
3. I have seen you now asking questions in your own thread and also in someone else's thread. Your main question seems to be can a CM 212 EVO cpu cooler keep the temps low enough to run with stability, when the FX-8120 is running 4.0Ghz all the time. THE TRUTHFUL answer is >> maybe or most likely, but it will depend on how h0t it is in the room where the computer case and parts inside have to function. It will also depend on the size and design of the computer case. Many cheaper, mid-tower cases have a tendency to have limited airflow, which can limit air reaching any cpu cooler and lower the cooler's effectiveness.
So there are a MANY things to consider and get correct to take an 8 core FX-8120 and hold it outside its' design limits all the time by overclocking, in a country where many have had to deal with very hot temperatures on a daily basis. I would suggest you tell us exactly by the items model and part number what you expect to use to make up your complete system; such as, case, power supply, motherboard, ram, cpu cooler, video card and anything else that will go inside the computer case. How 'hot' is the normal day to day temperature in the room where the computer will be located? Then what are the applications you intend to use daily on the computer?
So the short quick, not fully qualified answer to can "you" run an FX-8120 at 4.0Ghz using a CM 212 EVO for cpu cooling and the truthful answer is likely you can. However there are variables that might make that short answer yes but on the borderline of too hot all the time.
Let me say one more thing and I believe it to be a thoughtful idea by AMD, they have designed the FX-series of processors for places that are hot and power consumption is a day to day concern. The FX processors can go fast by their internal design and yet save power when not really doing any work. Not sure in certain global locations it is wise to setup the processor to defeat AMD's design for fast speeds and when doing nothing to save power. You and your own global conditions, will have to determine by 'room temp' and electrical cost/availability, what you really want to do. Good luck and good fortune to you sir.
