Here are my system specs.

AMD FX-6300
Kingston DDR3 2x4GB 1866
Corsair CX 500 Watt Powersupply
Powercolor Radeon 6870 1GB
2TB Seagate 7200 RPM
BIOSTAR A960G+ AM3+

So my friend plays league and counterstrike go, and every couple of minutes his frames drop drastically to 20-40 fps. At first I thought it was an overheating issue, but I ruled that out because of the following tests.

What I have tried.

1. Run Furmark, GPU stays at 82C, however league and csgo never goes above 70C.
2. Run Prime95 while looking at CPU-Z, temps stay below 55C, however after a minute the cpu clocks down to 1400 mhz and temps go down to 39C.
3. Use Catalyst to force cpu to stay at 3500 mhz all the time, change power options in windows to High performance. Issue number 2 still happens.
4. Disable V-sync, AA, and lower effects to medium in games. FPS drops still happen.
5. Go to motherboard and change fan settings to high performance, clock down ram to 1600 mhz.
6. Updated Bios

None of these has work as the frames keep dropping. The system is more than capable at playing csgo and league. I was playing at 200+ fps constant when I built it. The only antivirus installed in microsoft security essentials, no other background program is running.

Is this the motherboard?

My condolences, yet another "toy" motherboard that should have never supported 6 core CPU. The motherboard is very weak, only 3+1 phase, 2 mosfets per choke, 4 pin CPU plug, this is very weak.

Only chance. Undervolt. Disable Turbo and APM, try to bring the vcore while at stress inside Windows (use CPU-Z to see) to 1.23v or less, if you can pass stress tests. The lower you can go, the better.

For more details, follow my posts here:

Simply, the motherboard, can't make it to deliver the needed power, the VRM section overheats (being so weak) and you get throttling.

This motherboard should have support limit up to 65W CPUs.

After reading the MB, this is exactly what I was about tell him.

Ahh, didn't read about the 65 watt limit.. I also have the TA970 AM3+ in hand. Although only 4 pin cpu plug, it says it is rated 140W. http://www.newegg.com/Product/Product.aspx?Item=N82E16813138372

No, you misunderstood. The motherboard officially supports up to 95W CPUs. But, according to ME, it should only support up to 65W, because saying it supports 95W is a semi-fraud. The TA970 is 4+1 and with heatsinked VRM, it can handle the FX6300.

It's common thing with many manufacturers to make wild claims with TDP support. Several Asrocks say 140W TDP but throttle with 8-cores. Cheap MSI and ASrocks say they support 95W and throttle with FX6300, it has been seen again and again in this forum. It's deceiptful marketing, but nobody seems to care and make them pay a fine or something.

Try setting the CPU frequency in the Bios manually to 3Ghz and vcore to as low as possible(should be able to get 1.1 or so, if not lower) and retest. Getting the wattage down should be pretty easy. Most can do 3.5Ghz at 1.15-1.2 vcore. He may not need to replace his motherboard if he is ok with his performance with lower clock frequencies.

Assuming the board allows voltage adjustments..

He can also try putting a small fan blowing in the VRM area (where the 4 square things are and behind them), cool down, but that undervolting will have more effect. But the point is, the motherboard is really bad, if you can change it, it will be much better for the entire longevity of the rig. That motherboard, if any, should be able to handle only quads 95W. And Biostar claims it can handle up to 8-cores 95W. This is despicable.

I like that this motherboard says "smart" on its box. The only smart thing you can do with it, is not buy it.

I had the motherboard in hand because I used it for an athlon X2 rig iirc. I mean, he shouldn't need a new motherboard as he is only playing games like league and csgo. If only I could disable it so it can go four cores instead of 6. (Cores isn't really a right word, iirc the fx6300 is technically 3 cores, 6 threads?)

Yes, for an Athlon x2 it should be fine, they 're 65W. It's not your fault, it's the manufacturer deceiving users. This board should have never given support to 6 core CPU. The FX6300 is 6 core alright. Simply, there are 3 modules. Each module has 2 integer cores, sharing 1 FPU. So in total, there are 6 integer cores, sharing 3 FPUs. In BIOS, there may be an option to shut down cores. But, if you undervolt, there are good chances he can get away without having to disable any cores. Your call.

I guess I can do both. My pentium G3220 rig can play those games max settings 60fps, if anything 4 cores @3ghz should be able to handle those games fine as well. Thanks so much, I'll give it a try. If anything I can just buy a new 50-60 mobo or use the 970 in hand.

There should be no need (hopefully), to underclock too. Stock clock is 3.5Ghz.
