Help understand OC.

I am very new to building computers/OCing. Just built my first computer a month or two ago.

What exactly should I be reading off CPU-Z to determine if my OC is safe?

I also have CPUID to monitor my temps.

My current setup:

CPU: AMD-FX 8320

GPU: nVidia 760 GTX

MOBO: GIGABYTE GA-78LMT-USB3 AM3+ AMD 760G HDMI USB 3.0 Micro ATX AMD Motherboard

RAM: G Skill Value Series 1333 2 x 4GBs

PSU: 600W Silverstone

I understand I need to turn off the power saving settings, could anyone recommend a good multiplier speed?

I would try a multiplier of 23 and a voltage of 1.45v
Use ASUS RealBench or Mersienne Prime95 (Small FFT) to test the stability.
You don't need to fiddle with power saving features in most cases. I would try and leave everything at stock settings and apply the multiplier/volt I wrote above.
It's a safe voltage, and should be stable. If it's stable, you can try and reduce the voltage or increase the multiplier.
With a multiplier of 23 you CPU would run at 4.6GHz (FSB*Multipler=Clock speed: 200MHz*23=4600MHz=4.6GHz), which really is sort of a modest overclock for that CPU.
The voltage is the main variable when it comes to how hot your CPU runs. If you ran it at 2GHz with 1.7v, it would run very hot. 5.4GHz at 1.7v would run pretty much at the same temperatures. (theoretical numbers, all CPUs overclock differently (even multiple FX-8320s))

A CM 212 Evo should be able to handle it at 1.45v
Read a post with a guy running his at 4.7GHz 1.43v with a CM 212 Evo as well, it was reporting 63C under load. Might've been an 8350, but it's the same as you know.
 
When I'm just browsing I'm at 11c, during load which for me is playing games(tested Counter Strike Global Offensive) I peak at 28.2c.

What would be safe temperatures to run at if I were to be at a constant 4.6GHz?


EDIT: Tested a harder game to run and I peaked at 30.5c.. So I guess I'll have to run tests on a demanding game before I OC since my computer is meant for me to game on.

I need to know what temperature should I be wary of, I'm not looking to mess up my computer.

Also so it is possible to set a higher max clock rate instead of running at a constant one? IE: My multiplier can go from 7-23 or will I have to set it at a constant multiplier of x23

Run Prime95 for 12 hours, if the system didn't crash you are stable. 50 Degrees Celsius is good, 65 degrees max.

sorry but no cpu runs at just 28 degrees when you are gaming or 11 degrees idlle, ore you have it on ice 24/7 a week
 
If you are using watercooling or aircooling you can't go below the temperature of your room. Physics etc etc.
So if you live in an igloo it would make sense.
 
The motherboard CPU temp sensor will give you a closer reading. The CPU temp sensor is off on a lot of them.

CPU sensor is off it seems.

I have 3 temperature readings on my MOBO.
@idle(just browsing internet): 35c, 27c, 27c(the last two go up or down 1-2 degrees)

I ran a quick test on Counter Strike Global Offensive(this is a easy game to run) and the 35c stayed the same, first 27c peaked at 34.5c, second 27c peaked at 42.5c

Is RealBench or Prime95 easier to use?
And to clarify, stressing my computer with the programs stated will tell me if my computer can run stable through ALL processes correct? IE: If Prime95/RealBench confirms that my computer is stable, any games/programs I run will also keep the computer at a stable level?
