Hello, I have this problem with my new PC. My FPS drops from 65-70 to 15-20 for few seconds and then back to normal. This his happening every minute or so. I have tried pretty much everything and nothing helps.

Specs:

CPU: AMD FX 8350
GPU:Shappire R9 290 tri-x
Motherboard: ASRock 970 Extreme4 (last BIOS)
RAM: 8Gb 2x4Gb G.Skill Ripjaws X DRR3
OS: Windows 7 64bits

Screen of the iusse happening:

GPU-Z sensors. I pointed out the GPU Core Clock drop of when it happend.

All kind of programs, seconds after it happend.

It is also happening at Crysis 3 and others games. I dont know what it could be. Someone can help me with this?
Thanks in advanced.

Looks like CPU thermal throttling, what cooler do you have?

You have a Noctua cooler with CPU temps in the upper 60s. Something isn't right. You haven't overclocked (default Vcore and freq). Do you have proper air flow in your case? Did you apply thermal paste on the CPU when installing the cooler?

Well looking at your CPU temp 68°C is high for FX8350 especially with that cooler. Either the cooler install is not correct or the software is reading wrong. Your issues point to the software being somewhat right.

I'd guess something is wrong with your power supply or motherboard. Look at the min/max voltages. Your CPU Vcore is dropping from its maximum value by almost 40%. I'm surprised your computer isn't shutting down or randomly restarting because if that's what's really happening, I don't even know how your CPU is staying operational. If you have dynamic voltage enabled right now, disable it and try running at a known good fixed voltage.

edit: Also, as others have mentioned, try running with the side removed from the case and aim a fan at the motherboard.

The drop in Vcore is normal for CPU throttle.

Multiplier Voltage change auto basically when the rig throttles it will drop the vcore voltage because of the lower multiplier! In any case it would be a board issue not PSU since the voltage regulation is on the board!
You need to be looking at your cooling since it is the issue based on the temp!

Just looked at the picture and can you turn the cooler the other way (90°) since right now you are trying to cool the CPU with the hot air coming from the hottest GPU on the market!

I was going to say the same thing as rolli. Turn the cooler so it is exhausting out the back of the case not out the top. I did the same thing with my old Q9550 build and temps were always higher from sucking heat off my 460 GTX.

both cooler fans are working. Should I change the CPU's thermal paste?
I cannot turn it down 90º due to a rectangular backplate of AM3 motherboards(its not a square just have one position)

As a test turn the fans or just the the top fan and take the other one of and if you have a top fan stop it and see if it affects temps.

It could be a VRM issue.
This Asrock motherboard supports CPUs with TDP up to 125. Although the 8350 is advertised as a 125 TDP processor, it is actually a 140w TDP processor.
There is also a note on your motherboard's supported CPU page, that "For cooling the FX-8150 and its surrounding components, please install a CPU cooler with a top-down blowing design." (The FX-8350 is not on the supported CPUs list)

According to this, it is not on the motherboard support list:

http://www.asrock.com/mb/AMD/970%20Extreme4/?cat=CPU

My guess is that this mobo doesn't support any cpu with tdp higher than 125w.
Edit: It does actually support a Phenom II X4 140w TDP processor, but not the FX-8350. Maybe you should contact their customer service and ask them about that.

This could be related to your problem although it is an MSI board:

I've seen this recently in a couple builds. The fact that the CPU isn't on the supported list could definitely be the issue. People assume since the 8300 is on the list, that all 83XX CPUs are supported, thus taking it as a generalization. But that isn't true. The 8300 is an actual processor that's typically unavailable in the US unless it's an OEM.

Just for an inquiry with another thread, I emailed ASRock Tech Support just to see if it was a typo or something. Their response was if it's not listed, it's not supported.

Good catch.

The MSI board in the link I posted reported CPU temperature way beyond the actual CPU tempreture to throttle CPU speed to avoid overheating the VRM.

Still, reporting a temperature over the max temperature of the CPU would cause the voltage throttling, regardless how much the temperature is, or at least that is what I think. What is certain though is that this board doesn't have a bios that supports the FX-8350.

Well here is the funny thing from notes for release of BIOS 2.30 for the exact board "2. Improve AM3+ FX-8350 and FX-8150 CPU compatibility."
Looks like Asrock tech support replied with a standard safe answer when they do not know!

But why didn't they add it to the supported cpus list then? It seems like every FX cpu on the list is supported since the release of a certain bios upgrade. The initial version of bios only supports AM3 socket processors.

Good question maybe for the same reason MSI does not either in many cases and their US site support is different list to Taiwan list. That is lack of interest as an example Asrock has 2 EXTREME 3 versions and ver2 starts with Vishera support and has FX8350 the other one has the FX8300 only although it appears to be the same board.
MSI Has FXA990FX GD80 in ver 1 and 2 with the only difference being that ver2 had Vishera support out of the box and currently they only post BIOS updates on the first board and ver 2.0 has not seen a BIOS update for a long time even though it has its own webpage. They both use the same BIOS's since it is the same board.

Most people report similar AUXTIN temperatures so it is nothing to worry about.

So it's definitely my motherboard who is causing those problems?

I've read people who have this setup without problems, but 8350 is not on his supported list so i dont know.

If you can try to contact customer service and face them with the fact that they have a bios release which they say is to enhance support for 8350 processor while the processor is not on the motherboard's support list.

I don't think it's the temps. Or at least I have the same problem but at 45°C!
I've tried setting the voltages and multipliers manually to stock values from BIOS but with no effect.

Same motherboard, BIOS p2.40.

I could use some help as well, that's why i'm here :I...

Some R9 290(and 290X) models have cooling issues, and downclock themselves to keep the temps down. It's quite a well known issue, so you can just google it if the CPU fixing doesn't work out.

Mosfet or also known as VRM heatsink!

So it was a VRM issue after all. This is probably why your CPU isn't officially on the support list because the Mosfets can't handle its power draw so it throttles it down. I see you have strapped a fan above the Mosfets heat sink with a cable. How did you manage to do that (What did you strap it to)?

Originally they had that CPU on that list but with this board and many other they have pulled the support for the FX8320 and 8350 even their Extreme 3 990FX has those no longer on the list. They must have seen a lot of problems.

They could have revised the boards with better VRM heat sink though, although still passive cooling can only go so far.

It is bleak from a (High End) gaming prescriptive. The Kaveri chips may not have a place in the high end gaming market, but for entry level/main stream gaming and multi purpose machines they still compete. I don't think AMD will be able to be back in the high end CPU market any time soon though, if ever. Whether fusion proves to be the future and whether they will be able to push it further before going bankrupt remains to be unfold.

They do have a strategy that may help them at least become good enough again.

Mantle and DX12 are lowering the need for fast CPU's. Of course we have to wait until those API's take over, but if they do, AMD may be good enough again.

The term 'High End' is not restricted only to gaming, for example in most gaming scenarios the i5 is sufficient at the moment for a high end gaming PC, but people who use their PCs for 2d/3d rendering and/or other CPU intensive productivity oriented tasks will receive a far better performance from the i7. That is why you see the i7-4770k in a lot of high end workstations. Also whether AMD APUs will significantly benefit from lower level APIs or not is not certain; Mantle still has its issues and causes fps problems in BF4, and by the time DX12 will be out I expect Intel will even be further ahead of AMD in performance.
That is far off the topic though, I apologize to the original poster for my rant.

This is a thread about a gaming setup.

And Mantle has proven to help APU's a lot on the CPU end. Just not so much on the GPU side, as APU's are weak on both sides.
