Northbridge temp too hot while overclocking

I have msi 990FXA-GD65 motherboard, paired with Fx 6300. 

 

My stable OC for this thing is 4.4 GHz @ 1.34v (in bios). Previously i cant go 4.5GHz due cpu temp too high because in my h60's radiator,  only got 1 fan that exhaust the heat from the case. After i added 1 case fan to the radiator so the config is [outside] pulling fan <-- radiator <-- pushing fan [inside], the temps went down and i think i can bump it a little bit. 

 

I tried to go a bit further 4.8 GHz at 1.4v. I stress test it with IBT, very high at 20 runs. first it hangs.. Seems my vcore is not enough. So i bump it up..

-1.41xxx v, fails

-1.42xxx v, fails

-1.43xxx v, fails

-1.45xxx v...

 

When it reach that, the computer didnt hang but IBT reports that my cpu is unstable (/too high temps. Got a max celcius of 63 [cpu temps] and there is one is that already reach 3 digits.. 103 C on nortbridge. i was like omg. im about to fry the northbridge. 

 

So i set back to 4.7 GHz and at 1.40v.. IBT hangs.. meaning not enough vcore. When i bump it the vcore, 1.41xxx v, ibt again reports that my cpu is unstable/high temps. My northbridge is reaching 95 degress. 

 

My question is easy: Should i back down again? maybe 4.6? cause im a bit upset even after buying corsair h60, i wasnt able to get at least 4.7. (i think the answer is obvious lol)

I will say the MSI AMD mobo is the culprit

 

the VRMs are overheating

 

try to stick a fan onto the heat sinks or blow cool air over the heatsinks

What case do you have with what fan configuration? 

RIG: I7-4790k @ 4.5GHz | MSI Z97S SLI Plus | 12GB Geil Dragon RAM 1333MHz | Gigabyte G1 Gaming GTX 970 (1550MHz core/7800MHz memory) @ +18mV(Maxed out at 1650/7800 so far) | Corsair RM750 | Samsung 840 EVO 120GB, 1TB Seagate Barracuda | Fractal Design Arc Midi R2 (Closed) | Sound Blaster Z                                                                                                                        Getting: Noctua NH-D15 | Possible 250GB Samsung 850 Evo                                                                                        Need a console killer that actually shits on every console? Here you go (No MIR/Promo)

This is why you should not get an FX CPU for ANY scenario other than rendering on a budget http://linustechtips.com/main/topic/286142-fx-8350-r9-290-psu-requirements/?p=3892901 | http://linustechtips.com/main/topic/266481-an-issue-with-people-bashing-the-fx-cpus/?p=3620861

This. Even on my old crosshair v formula z the vrms were hot.....at stock 4ghz!

You do realize they call it Intel BURN Test for a reason, yes? It's one of the most ludicrous benchmarks out there. Run Prime95 for the sake of your hardware.

i will try that.. but if it already overheat @ 103 degress, why didnt IBT give warning earlier when it reaches 95 degress as at that point it gives the same errors also?

 

Currently stress test with IBT 4.6 GHz @ 1.35v.. NB temps was 81 degree and cpu temps are 51 degree celcius. it fails at 8th run showing the same error unstable/overheating. 

I guess its not the heat that makes it up. Results run 1-7 show something like 3.328891e-002. The 8th test that fail showing different numbers. This means wrong calculation.. From my point, wrong calculation / hangs indicate too low voltage that results instability. I just modify the cpu multiplier and cpu voltage, nothing else. for ram speeds i change it down from 1600MHz to 1333MHz. and moreover, im still a green at overclocking. Any suggestion for what to do next?

my fan configuration are 2 intake from the front, 1 exhaust at he top (although i can put 2 fans, the stock case fan is so thick that in the way of the radiator at the rear so i cant put the second fan at top other than buying other case fan), and finally a radiator with push-pull configuration that moving the air from case to outside.

Try aiming a fan at it first, then check those NB temps again and post back.

So Warm, very Marshmellow!!!

 

/Disregard, you posted right before I posted this.

Maximums - Asus Z97-K /w i5 4690 Bclk @106.9Mhz * x39 = 4.17Ghz, 8GB of 2600Mhz DDR3,.. Gigabyte GTX970 G1-Gaming @ 1550Mhz

yeah i know. it reallyy puts the unrealistic pressure on the cpu and produce crazy heat. Meanwhile prime95 is bit softer because at some time, there is a calculation that require a huge amount of power that produce heat and also one that require less power so the cpu temp will go down a bit. The downside of prime95 is obvious, ridicilous amount of time needed to call it perfectly stable. Minimum of 6 hours and recommended 24 hours. i guess my "impatient" is the culprit :P. But i will try prime95 tho
