Vishera FX 8320 goes only up to 4GHz (Water Cooling)

[McxCZ]

Hi there ,

straight to the question.

FX 8320 Vishera goes only up to 4GHz

When I push 4,1 or 4,2 , start Prime 95, temperature goes up to 43 C* then froze crash.. (Need to manualy restart)

1.465V (I tried pushing even up to 1.5V or 1.55V) nothing

I am only playing with the Multiplier and CPU voltage, Nothing else. I'Ve read somewhere that when it goes over 65C its a problem... But I never even get close to such high temperatures.

Please any advise thank you.

What is your current motherboard?

 

[maddogfargo]

What voltages and speeds for:

CPU NB (Not motherboard northbridge, CPU has it's own NB)

HT

MoBo FSB


Also, Have you turned Cool n Quiet, C1E, APM, Core Calibration, and all the misc power saving CPU features off? These will mess with stability.

You're probably not overclocking correctly. Here's a guide: http://www.overclock.net/t/1348623/amd-bulldozer-and-piledriver-overclocking-guide-asus-motherboard It should apply even if you don't have an asus motherboard.

As already asked above, what is your motherboard model?

 

[McxCZ]

M5A99X evo R2.0 is my Current MB, Yes I have turned off all these things. And nope I am not aware thaht there is a NB on a CPU ? WoW

 

[McxCZ]

I am proceeding now by the GUIDE JOOK-D sent here earlier.

You should be getting way better results than that. We'll be glad to know your success after reading the guide.

OK, couple things I noticed, I have made a terrible mistake with thermal compound, at 3,7 GHz stressing about 10 mins Temperature was 62-65 C (I've putted too much). I have scraped the Thermal Compound applied it as it says on the video now I am getting after 2 minutes run 54-55 C* Temperatures at 3,7 GHz stock clock. I will bee now pushing forward so stay tuned.

4,2 GHz , 6th Core keeps failing at stock Voltage, I am begging to raise the Voltage. But I am now far more further than before...

 

[McxCZ]

6th Core - 67 Celsius , 1.4125 Volts, keeps failing pushing voltage higher by one step per each prime95 test.

 

[McxCZ]

I'm getting stable 4,3 GHz at 75 Celsius , 1.5 Volts. If I push for 4,4 I have to raise up to 1,55 so it would stop crashing the 6th core. And the Temps goes up to 80 Celsius.

 

[JOOK-D]

I guess you have a bad overclocking chip. That's the silicon lottery.

Regardless, do not exceed 1.5v.

 

[McxCZ]

I will be buying about 2-3 120mm 2400 RPM fans I will be getting the to work together to blow more air through the radiator then I will post some info. Anyway I noticed when I start the prime95 it will start to make a little buzzing sound. And when I stop stress, the buzzing sound also stops. , Anybody knows what that is ?

 

[JOOK-D]

I had the same problem, it came from my PSU. What's the model?

Needless to say, my PSU blew out my CPU and motherboard... Hopefully the same doesn't happen to you.

 

[RobCrezz]

dont base the overclocking ability on prime 95 on the fx 8320/8350. Some some reason even when totally stable a core can fall off in prime95. but try with IBT or aida64 and you might find all 8 run fine.

 

[McxCZ]

TX750W Corsair. OK Ill try different bench program.

I had the TX650. Hope you don't have the same problem I did.

 

[McxCZ]

Anyway, any PSU you would recommend ? I am thinking about getting another GTX 470 this spring to Tri-Way SLI.

Depends on your budget. Do you need a fully/semi modular PSU?

 

[McxCZ]

PSU that can easily handle 3 GTX 470 plus overclocked FX. Budget doesnt really matter, but it is about 200$ or more (add 30% to U.S price of electronics to get europe prices.)

Whoah, that's cheap. Let's hope shipping won't cost much. But it is inside the EU so I think it won't be problem.

Another Question, If I buy stock coolers for my GTX 470s will it fit the GIGabyte GTX 470 and MSI ? Because, I noticed the cards that are having the original stock cooling and not the tri-fan cooler have a hole in it and maybe a different layout. Because TRi-fan cooling is great if you have only 1 card not 3 of those. Thanks.
