I recently got my second gtx 680. The issue is that im only seeing like 50-65 percent usage on both cards. My processor is overclocked to 4.5 so I don't believe i should be seeing these bottlenecks. When I run a game im only seeing about 20% cpu usage for some reason as well. I can run prime 95 stable and temps dont exceed 70c. Can anyone offer insight to why my gpu usage is so low and how to fix this? I've pretty much tried everything i can think of

I didn't think so. I'm beginning to think this has to be a power issue. my pc has no problem pushing 1 card to max. even if i have sli disabled and just have the other graphics card plugged in i still dont get 100 percent usage on the single card. does anyone else have any more insight on the power issue? is this a common problem associated with insufficient power?

yeah it definitely changes. i am getting SOME performance out of both cards. but the usage is about 40-60 on both cards.
edit: just additional information: i am running 8x/8x and my motherboard is the asus p8z77 v lk. I do understand that i will nto be able to acheive 99 percent on both cards however i assumed the scaling would be better than 60-70 percent usage.

Its more about the drivers then the cpu pushing them. I cant achieve 99% across both cards with my 760's in BF3 but that's just the way it goes.

But something must be wrong if he is only getting 20 FPS in Heaven.
@OP
what settings were you using in Heaven?

i understand. however i was looking at some benches of metro last light. my average frame rate with the same rez/settings is exactly about half of what the benches are getting. I know understand that its not my cpu bottlenecking them however, i dont know how i can make hte usage go up... it stays at abour 40-55 percent.... what else could be bottlenecking my system?

in heaven i am using the extreme preset. its the basic edition so its only whatever the default resolution. on metro ll. the benchmark im comparing is set at :1920x1200. everything on very high except SSAA . based on this benchmark

i should be getting around 100+ fps however my avg fps its 68.98

If you have the ability try to increase your memory size and also get 1866 or 2133 to see if that helps (It would have to). It is a win win either way because faster memory = more bandwidth.

You're crazy. His ram is just fine. It would do nothing to "upgrade" the ram. I would lean towards the power supply being the problem or possibly the motherboard due to 8x instead of 16x. But idk for sure on those just a guess

I'm having the same issue. I have the EVGA 680 reference card along side an ASUS DCU2 I just bought (both 2 GB). I have the 3770k @ 4.0 GHz, Corsair H60, 16 GB 1866 Patriot Intel Extreme Masters RAM, Corsair TX 750 (80 Plus), ASUS Sabertooth Z77. I'm seeing stuttering and worse framerates in almost every game I've tried... Max temps: EVGA (70 C), ASUS (50 C).

Do you have adaptive vsync enabled in the NCP? It should virtually eliminate micro-stutter if that is what you are experiencing.

Hi
I'm far from an expert but doesn't a GTX 680 use like 350W at max usage?
Ref - http://uk.hardware.info/productinfo/154739/evga-geforce...
Plus the 47W - 112W that your i7 uses..
Ref - http://uk.hardware.info/productinfo/148845/intel-core-i...
Plus 2 HHD'S, an SSD, RAM, Optical drive take up about 40W - 50W?
lets say 300W + 300W + 80W + 50W = 730W? Maybe power is the bottleneck.
I'd look for a way to see how your psu's power is being shared out

From looking this http://www.realhardtechx.com/index_archivos/Page362.htm
You and the op has the same setup sorta along with the same watts on the power supply..Im leaning towards the psu try getting a 850w in there and then see what happens..I honestly dont think its the mobo being x8/x8 instead of x16/x16 as well

According to Nvidia, the GTX maxes out at 195W (stock): http://www.geforce.com/hardware/desktop-gpus/geforce-gt...
Un-overclocked, the i7 IB is a 77W CPU at max. http://ark.intel.com/products/65523/Intel-Core-i7-3770K...
Although, I too am leaning towards the PSU being the culprit.

I went home and tried disabling hyper-threading. It took away all the drops in framerates that I was experiencing before, however I only tried that on Battlefield 4. I will try all my other games later to compare. If they are still running poorly, I may consider a new PSU. However, even at the bottom end @ 82% efficiency, the tx750 should be able to push at least 615 watts. Take away 195 watts for each 680 and I'll even say 100 watts for an overclocked CPU; it still leaves 125 watts for the rest of the system at worst case scenario.

It worked! It looks really good. I also swapped my cards' positions for better heat dissipation in the process. I made sure that the SLI performance was at maximum performance (which got switched back when I swapped the cards), and turned energy saving to maximum performance as well. I hope this helps anyone with this same issue.
