FX-8320

[PovilJ]

Hello, so I want to OC my CPU. Now I have it @4.1Ghz but I want more. But then I even have 4.2 it crashes. My MB: GA-970A-DS3P and CPU Cooler: CM Hyper 212 EVO. What whould you guys suggest?

Your mobo is kinda limited so you probably don't wanna go much higher

[Arcanekitten]

yeah but 4,1 is still great if you want higher buy a fx 8350 or new mobo

You might have lost the silicon lottery my friend.

Possibly better case air flow?

Just bought new NZXT S340

How many fans do you have?

How many fans do you have?

3

[owenrees1]

If any of those fans are blocked by something like an HHD cage, it could reduce the airflow. If that's the case (no pun intended) I would either buy some more fans or remove the HHD cage if possible

It's probably a combo of mobo and the CPUs overclocking ability. Even if you get to say for example 4.4 your not going to be gaining that much performance at all. Like when I Oc mine I don't get really any performance that's noticeable, unless I do benchmarks. Probably gonna go back to stock, maybe...

I think with OC CPU you can get couple more frames. On FPS games it really matters especially then I am streaming also with same pc

Be careful, that motherboard is notorious for problems with FX8 core CPUs.  Namely VRM overheating/throttling.  I would push it back down to 4.0Ghz and even then, get some direct airflow over the VRMs.

its supports FX i assume as well a OC

Supports and not having problems are two entirely different things.

 

For FX6 and above, you need 6+2 VRMs, but 8+2 is ideal.  Anything below that and your chances of instability of high.  That motherboard he has is a 4+1 VRM phase mobo, without heatsinks.

 

"Failures on motherboards with higher phase counts have been relatively infrequent if at all. Most of the culprits for VRM failures are the lower end 4+1 phase and 3+1 phase motherboards that aren't equipped to handle processors that consume lots of power and may be overclocked.  Smaller 4+1 phase systems or less on CPUs can be particularly risky due to the fact that each transistor must be capable of outputting more current and heat. This is why you normally see motherboards with low phase count failing (i.e. catching fire, frying, overloading), often on motherboards from only certain manufacturers or certain particular motherboards."

 

Here is the AM3+ Motherboard Phasing Guide.  In the notes for this motherboard, it even says: "Throttling at 90C - NO 125W Vishera FX support"

 

This is not a ringing endorsement, and we have seen plenty of people coming through these forums over the past year with problems associated with these low VRM phase motherboards and FX processors.  There are also the rare people who have success on such motherboards, but it is very rare, and still very risky.  It is just not worth the risk, especially when the upside isn't high and the pitfalls are pretty catastrophic in the worst case scenario.

 

This is why we say that AMD and Intel based systems cost the same.  With AMD, you are required to buy a high end motherboard just to get stable stock operations, then cooling to be able to overclock.  All of this adds up past the cost of an i3/i5, and no matter how high you overclock the FX, it will not compare to its respected Intel counterpart in the vast majority of games.

Oh thanks for this needed info
