Stuck on a 4.6GHz overclock with FX 8350 CPU. Cannot get any higher.

[gilgameshflood]

On 4.6 both CPU and motherboard temperatures are well below the danger levels. 47*C on CPU, 70*C on motherboard under full load(Intel burn test Max setting success).
CPU:                AMD FX 8350 Black edition
Motherboard:   ASrock 990FX Extreme9 Edition
PSU:                Seasonic S12II 620 Watts

Cooler:            Corsair H100I

RAM:               Corsair Vengeance DDR3 8GB (CMZ8GX3M1A1600C10)

Voltages, Frequencies, Settings and Temperatures at 4.6GHz:
___________________
CPU OC Mode: Manual

===================
Frequencies:                    Voltages:

CPU:       4600MHz           CPU:       1.4620 V                 
NB:         2200MHz            CPU NB: 1.2500V
HT BUS: 2600MHz            LLC:        100%;   Other voltages(NB, HT, VDDA) Auto.
RAM:      1600MHz

Temperatures: CPU: 47*C MAX; Motherboard: 71*C MAX.
 

Voltages, Frequencies, Settings and Temperatures at 4.8GHz:
___________________
CPU OC Mode: Manual

===================
Frequencies:                    Voltages:

CPU:       4800MHz           CPU:       Tried 1.5000-1.5352 V                
NB:         2200MHz            CPU NB: Tried 1.2500V-1.3000V
HT BUS: 2600MHz            LLC:        100%;   Other voltages(NB, HT, VDDA) Auto.Tried NB@1.2V
RAM:      1600MHz

Temperatures: CPU reached 54*C after four tests(Intel burn test "high" setting) and failed on the fifth. Motherboard temp was below 80*C. In HWmonitor Max CPU voltage only reached 1.5120V

I tried finding optimum NB, HT and VDDA voltages but found only NB voltage mentioned for a 4.8 clock in tomshardware forum saying "Using a 1.375 V CPU voltage and a 1.175 V northbridge voltage, I was able to get FX-8350 running stably at 4.8 GHz under full load.".
I'm not talking about CPU NB voltage here. As mentioned I Tried NB@1.2V
 

I'm new to overclocking. Any voltage or frequency changes?
Also tried LLC at 75% with CPU voltage set to 1.48- 1.50. It still failed the test(@4.8GHz).

UPDATE: RAM is running at XMP profile.

UPDATE 2: If anybody knows a good guide to FSB overclocking on this motherboard please mention it here. I want to see the difference in performance with multiplier vs FSB on this one.

Not all CPUs are created equal. 

The person who could hit 4.8 stable with his CPU won the Silicon Lottery.

I mean you hitting 4.6 is still pretty decent.

Some would be able to overclock higher than you.

You're out of luck 

Sorry bud.

So nothing wrong with my settings then? Think anything can be changed? Frequencies or setting NB, HT, VDDA voltages manually and try?

My first overclocking which is why I posted this.

I'm running my 8350 at 4.6 right now at stock voltages.  I can hit a tick over 5 GHz.  I got extremely lucky.  My step brother cant go over 4.6 stable.

If you cranked the voltage yet the system isn't stabilizing, there is nothing you can do.

You can cheat by returning the CPU and trying again with a new one but..

^This.

Nice. What voltages are you running at for NB, HT and VDDA? And what ram frequencies?

[The Crazed Child]

4.6GHz is excellent.

 

That would probably be equivalent to a 1.0GHz Intel CPU

/s

[rmac52]

I can hit 4.6 with everything stock except for the multiplier.

[Massa9]

is the CPU Ratio Multiplier the only thing your increasing ..speed wise? Or FSB?

hahaha, now that's a real joke

[gilgameshflood]

I am using only the multiplier. I don't know how to do the FSB thing. I tried the FSB but No matter what HT and NB frequencies I set, I get stress test fail. 

I can't find any guide helping me with fsb overclocking.

Thanks. Thought It was something I did wrong.

Tried it with the same HT and nb frequencies he has on FSB mode and got stress test fail.

Of course it did, what where you thinking. All processors are created differently. You cannot just go and replicate the settings and then expect it to work. You have to tailor the overclock to your own chip. With that set up you should be able to really put it to the max, but since all you can achieve is 4.6GHz, than that is the maximum. There is no point of trying if your processor simply doesn't have it in it.

Yup. OriginalPromise already established the fact that my CPU overclock has reached its limit. Sorry for my last reply. It was very unclear what I intended to say.

What I forgot to mention properly was that in the FSB overclocking method showed in Jayz TwoCents video, I could not get even a 4.2GHz stable overclock using NB and HT frequencies closer(more or less) to defaults(I tweaked around with the frequencies).

So something wrong with my motherboard settings maybe? I can only get the multiplier overclock to work. 

I will ask about this to ASrock customer support.

Thank you all.

Yeah, I get 4.6 on this MB at stock voltages no problem just using the Auto overclocking settings. Haven't tried over volting yet, but crashes at 4.8 at stock voltages sometimes during boot, sometimes after. I've even gotten into a game of battlefield 4 and THEN it crashed. So, it's not like it's THAT far off.

 

I'm sure it would be stable with over volting. This motherboard has been stellar so far. It's made of all premium parts.

 

My previous board, an ASUS M5A78L-M USB3 was supposed to be overclockable but would never go above 4.2 without crashing after more than 20 minutes. I thought I had a bad CPU until I replaced the Motherboard. Suddenly everything works fine and my processor is rock solid and overclocks like a champ! At 4.6 with a Coolermaster Hyper 212 Evo (best CPU cooler for the money - hands down!) it never goes Above 54C under full load SO far. Knock on wood!

 

I'm gonna try for 5.0 for sure! That's why I bought an FX-8350 in the first place.

 

Good luck to you.
