Low gpu usage and low fps GTX 770

Traiden · Nov 26, 2015

Hello, I was wondering if I could get some help with this. I've been having low fps and stuttering issues for a while now. As far as I can remember, it started with Thief (I assumed it was just the game being poorly optimized) and more recently GTAV and Fallout 4 (at this point I was starting to think maybe I need a new graphics card, but even at medium settings on Fallout 4 I have horrible fps and low settings on GTAV I can't even drive a car because it gets so bad).

GPU temp doesn't go above 48, CPU temp max has been 52. FPS with Fallout 4 one medium settings are typically 20-35, but have had it stay as low as 12 for a while and have had it briefly go up to 52. GTAV had similar fps on low settings. GPU load is typically between 12% and 20% but has gone up to 52% (very rare and I believe this is when I have seen the most fps) and also drops down to 4%-8% but has been as low as 1% while playing.

I have been searching everywhere for a solution and all the ones people have recommended havent worked.

I don't over clock (I believe the card was over clocked a little by Gigabyte), I have tried turning Vertical sync off in the NVIDIA control panel as well as AA - FXAA, I reinstalled my drivers, my cores aren't parked (as far as I can tell).

Any help would be greatly appreciated. Thank you.

Specs:

AMD FX-8350
16 GB 1866 MHz G. Skill Ripjaws series
Gigabyte GeForce GTX 770 2GB
ASRock 970 Extreme4 MOBO
750 XFX 80+ Gold PSU

The gtx 770 is a very capable card to run those games at high settings on 1080p..

Check with driver update first before we blame components

Traiden · Nov 26, 2015

Like I said, I already reinstalled the drivers. I'm currently running 359.00 whql released on Nov 19th, 2015. I had also tried uninstalling GForce Experience, but that didn't seem to do anything so I reinstalled it. And I have uninstalled the NVIDIA HD audio drivers.

Monitor your cpu frequency. Boards has a weak vrms setup and could be throttling the cpu.

Traiden · Nov 26, 2015

According to CPU-Z my cpu frequency hits 4090. I don't know if thats what you mean by monitor it, or if just because it is hitting 4090, that it is actually staying there for any length of time while I'm playing a game. Just looking at CPU Z, it changes beweent 1396, 2793, and the highest it as been so far (that I have seen) is 4150.

Check if your xfx psu is emitting any strange noise,

Traiden · Nov 26, 2015

How do I do that?

Edit: And if you literally mean noise and just to listen to it, I'm going to feel stupid.

plaintuts · Nov 26, 2015

Yeah listen to the psu.

Check if therea any coil-whine or sorts

bignastyid · Nov 26, 2015

Grab something like occt and stress the cpu and watch the cpu frequency and see if it drops.

Traiden · Nov 26, 2015

PSU sounds fine (as far as I can tell). Downloading OCCT right now. Will this stress my cpu on it's own or will I need to play a game while it monitors? Either way, I'll let you know what the results are afterwards.

Traiden · Nov 26, 2015

Graph of CPU frequency over time with OCCT: https://i.gyazo.com/8e067bc37bfd11d7e3fafac986883def.png I only ran it for 3 min 44 seconds. There is one big drop at about the 45 second mark, but after that it seems pretty stable (varying between about 4000 and 4066MHz).

Traiden · Nov 26, 2015

I'm letting it run longer still, but I'm noticing the frequency dropping every so often to about 1500. Also, each frequency drop corresponds to a decrease in voltage. These drops are also happening only when the CPU is reaching a temp of 60C. It will be at 60C for a little while, it's not like it drops the second it hits 60C, but it is ONLY dropping while temps are at 60C.

bignastyid · Nov 26, 2015

You have a throttling problem. If i remeber right an amd fx cpu will start to thermal throttle at 62-70°C.

Traiden · Nov 26, 2015

So how do I fix this? I'm really hoping it isn't just an over heating issue. Core Temp says my cpu temp never went above 52. While OCCT was running, my fan speeds didnt increase at all. I have 2 200mm fans, 4 120mm fans and the CM Hyper 212 EVO CPU cooler. Is OCCT correct and it really is getting to 60C? Just about every other program I have used in the past has never shown it to get that high.

I have to head to work now, wont be on until late tonight possibly tomorrow evening as I also have to work 4am to 4pm after my shift tonight.

bignastyid · Nov 26, 2015

Vrm throttling usually doest show up in temp readings. The only real fix is a new motherboard with a better vrm setup.

Traiden · Nov 28, 2015

Does that also explain the low GPU load?

Traiden · Nov 28, 2015

I played fallout 4 for a while with OCCT running on my other monitor. The temp stayed between 51 and 51.6 the whole time and I didnt have any frequency or voltage drops (that I noticed any way, but it was happening often enough while running the stress test, that I would think I would notice if it was doing that while playing Fallout 4--especially when my fps drops really low).

Edit: Never mind, I just had a frequency/voltage drop--completely froze the game for a bit.

bignastyid · Nov 29, 2015

The throttling is a problem but I dont think its the only problem. Get gpuz and what does it show for bus interface? Click on the question mark next to it and run the render test and see if changes.

Traiden · Nov 29, 2015

I already had gpuz. Bus interface is listed as PCI. The render test ran smoothly, didn't stutter or anything visually. Here is a screenshot of the sensors tab after it had run for a little while: https://i.gyazo.com/0bdabce06c81d6afc295abf582f4800a.png When I had had it up while playing fallout 4, I never sawn the GPU load get above around 35% Here, you can see it got up to 93%. I'm not sure if it should be fluctuating like it is or not though.

bignastyid · Nov 29, 2015

When running that test it should have pegged the gpu usage to 99%, you bus usage seems high. Where it says bus interface it going to say more than pci, it should say something like pci-e 2.0 x16 @x16 2.0. Post what it says next to bus interface and also post what it shows on the bottom left corner of the render screen. Memory usage is also rather high I use under 500mb when running that test @1080p. What resolution are you running?

Traiden · Nov 29, 2015

Here is a screen shot of the graphics card tab: https://i.gyazo.com/2635fc73328b9189a93b2ce44f760af6.png Next to Bus interface, it just says PCI, unless I'm looking in the wrong spot. In the bottom left of the render screen, it says: NVIDIA GeFORCE GTX 770: PCI.

On the screen shot of the previous test I ran, it opened the render test in a bordered window. The full screen option says its for SLI/Cross Fire as seen here: https://i.gyazo.com/50b2db0e9b25b552f5bb1e867afc58e1.png

Do you want me to run it again in full screen? Also, when I ran it the first time, I had a non-graphically intensive game running in the background (minimized).

My resolution in control panel is set to 1920x1080 for both monitors.

bignastyid · Nov 29, 2015

Ok, thats odd it says PCI. Try updating your chipset drivers

Traiden · Nov 30, 2015

Ok, heres a question. According to newegg, my mother board should have the AMD 970 + SB950 chipset. However, according to CPU-Z I have the RD9x0 chipset. Any ideas on how I know which?

Edit: Nevermind, went to the ASRock website. Should be the AMD 970 chipset. Which doesn't seem to be on the AMD website. At least not in the drop down when you click drivers. It's not part of the APU drivers, is it?

Traiden · Nov 30, 2015

Ok! So, I installed them. Good news, GPUz now reports that my GPU load is 99% (it did briefly drop to 97% and 96% at different times) during the render test. Bad news, after about 5 minutes my computer froze, I lost signal to my monitors and then my computer reset itself.
