HELP! Low FPS with dual SLI 670's

My FULL system specs:
PSU: Thermaltake Smart 750W Bronze
Ram: 2x 4GB Corsair Vengeance
MOBO: Asrock z77 Extreme 4-M (mATX)
HDD/SSD: OCZ Agility 60GB/ Western digital 1TB Caviar Blue
CPU: intel core i5 3570k (stock clocks @ 3.4Ghz)
GPU: GIGABYTE GTX 670 OC EDITION 2GB/ EVGA FTW GTX670 2GB
1920x1080 Resolution Acer Monitor @ 60Hz

Edit: these were my results on Windows 7 taken from MSI Afterburner;

I've tried reinstalling the drivers and changing the 'parking' with windows 7, but no luck.
I get better FPS with 1 670...


EDIT: This problem is now fixed! Windows 8.1 Fixed it along with the new Nvidia drivers! ( I recommend anyone with my problem to install Windows 8 Immediately! (thank you to everyone who helped)

  1. What resolution are you playing at? Your cpu is probably getting maxed out (regardless of what anyone else says I see my 3570k get all 4 cores maxed out with 7870 CF). Open task manager>performance to see cpu and RAM usage. Use MSI afterburner to see gpu 1 and gpu 2 usage. While in game watch those graphs. What is gpu 1, 2, gpu memory, cpu core (ignore average usage) usage, and RAM usage?
  2. Did you try firemark or another benchmark?
  3. You will need to provide more information, using MSI Afterburner or EVGA Precision check what the GPU usage is on each card and post results.
  4. alright, im playing bf4 on medium and its running pretty choppy, i'll post results soon.
  5. Edit: CPU usage is at 92% in Task manager
    CARD 1
    GPU-Z Current temp is 43c
    with a GPU load of 40-45% average 53% Max
    Core Clock 979.8 Mhz
    memory clock 1502.3 Mhz

    CARD 2:
    Core clock 1006.6Mhz
    memory clock
    1552.5 Mhz
    Temp 50c
    memory used 1121MB
    GPu load 34%


    Edit 2: would it be easier if i used MSI afterburner instead of GPU-Z?
    also im experiencing some high microstuttering..
  6. You might have some of your cores disabled make sure turbo boost is enabled and that a 4 cores are active you can do this in the extreme tuning program, or you can type msconfig go into the boot options then click on the cores box to check it, and then set your cores to 4. Then reboot

    Hi, thanks for the reply I tried doing it in msconfig, but I dont know what you mean by the cores box to check it?
    I go to the boot tab, then advanced?
  9. In the advanced boot options tab click on the first fox in the upper left corner and then select 4 for total cores then reboot

  15. So did it help at all?

    I tried playing on ultra and no success, even high is laggy. Even with a single 670 i got better results, I can't work out what it could be. It's just straight up horrible performance, I don't know what to do...
  17. Most likly poor driver support for that game in sli for you cards. I think the next step would be is to call the card manufacturer and see if they know of anything. It could be your power supply but i doubt it

    I read on other forums people with similar SLI configs are saying as soon as they went to windows 8 all the problems went away? I don't understand how this even makes any type of sense? I previously had Windows 8 before SLI'ing today.
  19. If you have the disk and everything go ahead and try it on windows 8 that would be my next step

    I don't anymore... I'll have to re-buy it. It's used on the other computer.
  21. You said 92% average cpu usage. I'm about 99% sure that means one of your cores are maxed out. Do it again but only look at the core usage graphs. If you see one core maxed out then it's a cpu bottleneck.
  22. If you have the disk you can install it without activating it just to see if it helps

    How do i check each core individually
    Edit: I ran single player and I was still getting awful results, is this a bottleneck or something else?

    Ah I dont I only have the beta which is unstable..
  25. ...anyone?
  26. Task manager shows a graph for each core usage. Just looks at all four graphs to see if any are hitting the top.

    They all seemed to have I just OC'd my CPU to 4Ghz and still no avail. I posted on the GeForce forums and they told me to install windows 8 and then reinstall drivers ? I don't know what to do anymore...
  28. Think about it, all four cpu cores are at ~100% usage and your gpus aren't. That is exactly what a bottleneck is. Now what you should do is see what is using your cpu. Maybe something besides the game is running.

    Just replying to say Windows 8.1 Pro and the new nvidia drivers fixed it for me!

    Also, I think my CPU is bottlenecking in MP, cause in SP I get flat 60fps with vync but in MP in really intensive areas I sometimes drop to 40 or even low 30's when theres lots going on

    I OC'd my CPU to 4Ghz but I dont think its enough, I only changed the multiplier.

    I oc'd my CPU to 4ghz but I think it need to OC it more, problem is in my BIOS theres no option to change the voltage at a fixed rate, only offset!
  31. The area might be grayed out but if you just hover over it and disable the automatic option for voltage you can change it. I really highly doubt your processor would be bottle necking your system. The difference between your processor and a new i7 would be within the margin of 2-5 fps. But I forgot to post this to you but I did do a little more research and I found out nvidia has better sli support for your cards for bf4 in windows 8.1 What I would do is try future mark and see what score you get and compare it to others with systems like yours. If you score high in benchmarks and low in games that would make it certain that there are no bottlenecks and it truly is just bad driver optimization from nvidia for sli for your system. Your processor wouldn't even bottleneck two titans in sli let alone two 670's. The bottleneck is snake oil don't believe it.

    Alright, 'll test out FutureMark now, so what do you think the problem is? because a mate of mine has SLI 480's and he gets a constant 60FPS in bf4? for some reason it just wont stay, but once i take off vysnc it exceeds 100fps!? I just don't get it. So i should disable the voltage? it does have offsets of -0.100 etc, do I just play around with these? because i just OC'd to 4.2 and the voltage is around 1.221-1.226 which is too high I saw a video and a guy with the same CPU as me was sitting at 1.1 easily without any effort. In heaven I know I scored 1506 or something, my cards were working fine with clocks of 1300Mhz with one higher by 6 or 7 Mhz (The EVGA). I have read though that it can bottle neck because its such a demanding game in MP, in single player it was a breeze I was capped at 60 FPS with the rare occasion of 59-58!

    But I will research and compare my score, I'm not sure if my score was low because I had my Frames capped in EVGA precision X though..
  33. It could quite possibly be a problem with the sync. I would just keep it disabled and play the game without it. I think the only time you should have that on is if you notice that your frames are really out of sync or you hear something weird like coil wine. I actually took my two 780 Ti's and I put them into my old 3570k system just to test out my theory, and the fps difference between my i7 4930k and my 3570k was only about 5 fps. So I would just keep vsync off unless you run into issues with it. I would always recommend an overclock on a K edition processor as long as you have it stable and you have an aftermarket cooler

    yeah I have a cooler, I got 1806 for my heaven benchmark this time.. not bad I guess? see the problem is I'd play the BF4's vsync but if gives em HEAPS of input lag in my mouse, feels like it floating around and the only way to fix it is locking the framerate with dxtory or EVGA. I have my CPU at 4.2Ghz stable but the voltage just seems too high.. especially for only 4.2Ghz! any ideas? have you OC'd your 3570k?

    here's my Full system specs:

    PSU: Thermaltake Smart 750W Bronze
    Ram: 2x 4GB Corsair Vengeance
    MOBO: Asrock z77 Extreme 4-M (mATX)
    HDD/SSD: OCZ Agility 60GB/ Western digital 1TB Caviar Blue
    CPU: intel core i5 3570k (stock clocks @ 3.4Ghz)
    GPU: GIGABYTE GTX 670 OC EDITION 2GB/ EVGA FTW GTX670 2GB
    1920x1080 Resolution Acer Monitor @ 60Hz
    CPU Cooler: Noctura dh14 (I think)
  35. I think anything below 1.3 is good. I think for a lot of people 1.22 is kind of the sweet spot but it depends on the quality of the chip.

    So you think 1.22 is alright for an OC of 4.2Ghz? If so i'm happy with it, I just don't want to under estimate what I can get from my chip.
  37. Best answer
    1.22 is the sweet spot that is fairly common. Just stick with it. I had mine all the way up to 4.4 but it took me a long time to dial it in.
