I have a decently power hungry system and I am wondering if 1000w is enough. I am getting GREAT temps for my CPU, VRM's, and GPU's and have no idea why on demanding games like Battlefield 4 and Crysis I get huge FPS drops after a round online or two. My specs are as fallowed [email protected], 16gb 1866 ram(2 dimms), asrock 990fx killer, crossfire 290x(reference cards, 100% fans speed as limit in CCC, no overclock) Have a dvd burner, 3 hard drives, 1 raid controller, 1 SSD, as well as corsair h105, and 7 fans... My PSU is a EVGA Super Nova 1000G1.
Your power supply should be more than plenty for that system.
What happens if you revert your 8320 to stock clocks? Also, try putting a fan blowing air towards the GPU s and see if that helps.
All temps are great... Still same issue on stock.
Having similar issues on my 8350 and 780...using a shitty 530w PSU tho
The power supply is more than enough, and the PSU only has one 12v rail, so its not starving your components because of an overloaded rail.
I would recommend testing your RAM. Run memtest x86 for 24 hours, sporadic isues like this can be ram most of the time.
your problem is, that your GTX780 gets bottlenecked by your FX8350.
It has nothing to do with your psu´s guys.
290X CF same story, its not the psu.
You just get bottlenecked by your cpu.
The Asrock 990FX killer, is not the best overclocking board either i have to say. its a nice board for its price with nice gaming feutures. However wenn you gonne overclock passed 4.5ghz the vrm´s of this particular board start to run hot. and can causing voltage thorttle, since there is no LLC option to correct these voltage drops. this will automaticly results in cpu throttle.
But you said that you still got good vrm temps, so i still say like i told you before.
Its a cpu bottleneck
I'm not sure why you deleted your previous comment and mine, as they explored a more plausible issue.
He is having the issue after a few rounds as in his playing fine at first, and then it happens later. A sporadic issue. If it were a bottleneck, he would be constantly facing the issue.
Your original idea about possible VRM issues was more likely, but because he was facing the same issues at stock CPU speeds, its probably not that either.
I still vote run memtest
i edited my post.
FX8350 cannot even handle 1 290X on its full potentional all the time. in cpu + gpu bound scenario´s let alone 2.
FX8350 also bottlenecks a GTX780TI and GTX780.
BF4 multiplayer is gpu + cpu bound. thats why.
Running mem test is offcourse a good advice.
He does have a CPU bottleneck, the FX 8350 can't keep up with the CF R9 290Xs for sure. But not so much so that he should be suffering a massive framerate drop later in the game, average frame rates dont just randomly fall out as if CPU is randomly going throttling itself after playing a couple rounds. They are just lower than ideal in a bottlenck situation.
That being said, your system would benefit from a better CPU, i5 4670k comes to mind, but that is not the reason for your issues you are describing.
Well i can tell you, that allot of people suffer from the same issue, with a similar configuration, its discussed on allot of diffrent community´s allready.
Cpu bottleneck is the only thing that i can think off.
Unless he has a problem with the mobo or what not. but that doesn´t sound very likely to me.
I dont know in what situations he is playing online. if he joins an allmost empty server, which getting full after a while then yes, it could still be the cpu bottleneck
So OP, a possible test for the bottleneck theory is to take one of your 290x's out at test. Or just disable crossfire in drivers and test.
yes.
He could try that.
But he still wil suffer from fps drops, as soon as he gets in a crouded spot, with allot of explosions and people going everywhere. this is just the weakness of the slower fx cpu's. he can enable mantle, which i highly recommend.
I would also recommend to test both cards sepperatly, just to determine if not one of your cards are faulty.
This is probably true. He will get FPS drops in those situations. But that wasn't the symptom he described, he said ithappens "after a few rounds". That makes me think it is happening even when he is NOT in a crowded spot with lots of people and explosions.
BF4 is also plagued with issues, it could very well just be BF4. OP does it happen in any other intensive game?
OP also stated it happens in crysis 3.
Well this is the same story basicly, crysis 3 single player is GPU bound, he will not suffer from big frame dips.
However, as soon as you go online, like op does. then the story is the same as with BF4 multiplayer. only Crysis3 is even more gpu heavy. Crysis 3 multiplayer is cpu + gpu bound. mantle could help some. But i dont know if mantle realy works well with crossfire.
Mantle would help, but you are correct in your hesitation, it does not work well with Mantle. This is because unlike with DX, Mantle leaves Crossfire optimization up to the game developer, as opposed to being supported by the drivers
Not a power supply problem, as MisteryAngel said.
If your power draw is greater than what your power supply can provide, your power supply will either shut off due to over current protection or heat protection or explode, depending on the quality of the power supply.
yeah well its still a very difficult issue, because yeah dips below 30 is realy terrible.
I can remember those graphs you posted 3770k vs FX8350 with CF7970´s. in skyrim. the FX still did scored a decent 90+ fps, however it wasnt able to drive the CF verywell on 1080p. Still the avarage fps in that graph looked okay. But yeah skyrim is single player. basicly a cpu bound game.
There is realy a big diffrence between single and multiplayer. wenn it comes to cpu performance. like i said crowded spots allot of explosions unexpected things hapen people move everywhere, and those gpu´s all have to render that. There is where the FX8350 starts the struggle to keep up with the higherend graphic cards. It starts to dip at a certain point. This is basicly an issue in allot of cpu + gpu bound multiplayer game, and FX cpu´s.
I realy could not believe this my self, the first time i readed about this. i could not believe that a FX8350 could holdback a single gpu. But i saw this discussed on allot of diffrent community´s.
But yeah basicly its not that the amd FX is realy bad, because believe me, also intel suffer from this dont worry. But the only adventage of intel is, the more powerfull single cores, with better ipc. This is the reason why you see more stable minimum frame rates on intel cpu´s in cpu + gpu bound games or scenario´s.
But i do agree, that it still strange that it happens after a few rounds, unless the server is crowding up at that moment.
So yeah it could be that he suffer from 2 diffrent issues. If im right killer nik had also some driver issues, killer nik uses more cpu sources then intel lan for example. maybe try newer lan drivers aswell.
i realy hope that this problem can be solved very quickly.
Listen, I truly understand. I get the concept of GPU vs CPU "bound" IN BF4 there is alot more calculations going on in MULTIPLAYER vs in SINGLEPLAYER because of interactions with so many things.
IN bf4 SINGLE PLAYER SLI WITH LATEST DRIVERS, the FX 8370 keeps up, unlike in Skyrim.
And I understand there IS A PERFORMANCE HIT in multiplayer. But he didnt come here and make a thread saying, "BF4 works fine in single player, but in multiplayer it lags"
He said it works for a few rounds, and then lags like crazy. He didn't say he walks into a crowded area with lots of explosions, and then lags like crazy. That DOES NOT sound like he is just being slowed down by his CPU.

As Jay has been saying for over a year now, BOTTLENECK is a word over-used and mis-understood.
This is w/ BF3 not BF4, so its not apples-to-apples with this thread, but its does help us point the indicator in the direction of some kind of system problem. Skip to about 10:00 on the video.
