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

McxCZ · Jan 31, 2014

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 · Jan 31, 2014

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?

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

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 · Feb 1, 2014

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

McxCZ · Feb 1, 2014

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 · Feb 1, 2014

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

Regardless, do not exceed 1.5v.

McxCZ · Feb 1, 2014

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 · Feb 1, 2014

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 · Feb 1, 2014

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 · Feb 1, 2014

TX750W Corsair. OK Ill try different bench program.

JOOK-D · Feb 1, 2014

McxCZ :

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

McxCZ · Feb 1, 2014

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

JOOK-D · Feb 1, 2014

McxCZ :

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

McxCZ · Feb 1, 2014

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.

McxCZ · Feb 2, 2014

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.
