Hello everybody. I'm new here, even tho I always looked here to find any troubles I had. But this time, only reading posts haven't worked, so I have to ask.
So, at the begin of year, my computer stopped working and they said it was the motherboard. After that, I noticed my computer is no the same. Then I thought "Ok, maybe my graphic card is also damaged". Turns out I bought a new GPU and gave the old one to my girlfriend. Now she is the happiest girlfriend in the world cuz it's working fine on her computer and I still have the issues.

Every game I had that, specially online games when things get intense (Team fights on MOBAS, or crowd of mobs or raids on MMO's)
Games I usually play nowadays: Diablo 3, Blade and Soul, League of Legends.
LoL and D3 should be a walk in a park on a sunny sunday for my GPU!


I tried many stuff, like overclocking GPU, overclocking CPU, unparking cores, defrag disk, I alredy changed from win 8.1 to win 10 and back to 7. I tried V-synk, uncheck V-synk... Also turned on triple buffering. Changed resolution...

Then I read something:
"'I would bet that your new board only has a 4pin power connector by the CPU and the old board has the full 8pin connector required for a 125w CPU.'

Confirmed.

Thanks a lot. Thank god i didnt buy this motherboard, i just borrowed it"

My config is:
ASUS M5A78LM USB3
16MB ram
GeForce GTX950
AMD Fx 8120 8-core
CORSAIR 600W
CORSAIR H55

Well then. I went to my mobo's web and:

ASUS M5A78LM USB3
AMD AM3+ FX™/Phenom™ II/Athlon™ II/Sempron™ 100 Series Processors
Supports CPU up to 140 W
AMD Cool 'n' Quiet™ Technology

I also checked for my CPU and it's 125w.

125<145. Awesome, should work.
But I got curius and opened my case and unplugged that big/thick cable that goes to the mobo, and yeah, my mobo only uses 4 pin out of 8 that the power supply offers.

So, that 4 pin might be the problem? Should I get a fx6300 (95w)?
Also, why does it say it supports 140W if the pin only works for 95w? Can anyone check if my mobo indeed is 4 pins? I mean, maybe the box had the wrong mobo? Anyway I can check this?

Thanks in advance! Sorry for my english.

EDIT: Forgot to mention, I have my gpu driver updated thru Nvidia experience, v368.69.

EDIT2: Someone told me to download CPU-Z and prime95 for testing. He asked me to check my core speed, and during test it would drop to from 3100 to 1400, then up to 2800. Bu yeah, constantly dropping to 1406. He said it should stay constantly at 3100 during the test.

Also he gave me a link, but didn't work either:

That motherboard that you have, as you have concluded cannot not supply the CPU with with enough power for a long time, and is causing your CPU to throttle, that means that your VRMs are probably overheating, your mobo doesn't even have heatsinks on the VRM making things worst, and you could eventually kill the board.

The best solution would be to get the correct mobo for your CPU, one with 6+2 phases like an M5A97 EVO, in the case of ASUS.

I see, thanks for the awnser!
That mobo you showed me is quiet expansive for me right now, fx6300 is about half of it's price. Do you think that would solve the problem?
I could just store my processor for now, and use it again on another system in the future once i get a better $$$ituation.

I can't tell you for sure if a weaker processor could solve the issue, but placing a fan on top of the VRM could help, another thing that you can do is to disable some cores, you should be able to do it in the bios, I will try to get you some more info about it.

VRMs are those transistors that are between your CPU and the back connectors, very close to your CPU power connector.

You see, those 8 transistors close to the CPU power connector, they work in pairs so your Systems is a 4+1 I think, but the best option right now would be to disable some cores, so you don't have to buy a CPU that you already have.

For this go to your BIOS by restarting your PC and pressing DELETE when its posting, and go to your ADVANCED tab, and select CPU Configuration, there you should be able to see something like CPU activation, change it to Manual, and the core disabling should be available, if it didn't had it available already.

Just done that. Turned off 4 cores. It seens those drops from CPU-Z stopped, also I enabled "overclock profile" to 5% in the bios, and it went to 3.5mhz. Now I just have to play my games and later I'll come back and tell if they became more playble!

If that fixes it., guess I'll just start saving money for a new mobo+intel processor. Heard that geforce works better with them.
Any suggestions for my set up? That's isn't too expansive but cost effective.

The things are changing too much to recommend anything right now, and the new mid range cards are just arriving, so I would keep my eye in the GTX 1060 from nvidia and the RX480 from AMD, unless you have the money to go for the 1070 because that would be the best choice in my opinion. Anyway, going for an i5 6600 or something similar is a very good idea, unless you plan to wait until next year for Zen to come out.

Meanwhile you could apply install some heatsinks on top of those VRMs like in here:

You can find some around the internet like these:

So, I just played League of Legends and blade and soul.
Blade and soul is working better than never, LoL was on max settings, with locked 61 fps. Guess you figured it out! Ty a lot for your time and help! If there's any trouble, I'll update this post, but seens like I won't have to :)

It would be most likely because those games don't use more than 4 cores, but if necessary you can either overclock it some more and do around 30 minutes of Prime 95 to check for stability.

Will try that. I tried 10% but my computer had some video failures before it restarted and pointed overclock failure. I can try again with 8%.
I didn't try much with 6 core also. Think worth give it a shot?

Most likely you were lacking Core voltage, also using automated motherboard overclocking is not a good option, you can find good overclocking guides around, like this:
http://www.overclock.net/t/1348623/amd-bulldozer-and-piledriver-overclocking-guide-asus-motherboard/0_100#

Just keep it under 4.5 due to your VRMs, but with 4GHz, should be enough.

Like I said, I havea 8-core, but I deactivated 4. I wanted to raise it to 6. I tried looking around on google but couldnt find.
How did I disabled then? I used msconfig and advanced boot options. Why can't I revert? It only shows me 4 or less cores, I can't really enable the ones I disabled before. How do I revert it?

That's the guide I followed.

Anyway, I actually found the options in my bios. Not sure if its the same thing. If you think in the bios i'd get better results, let me know.
