hello, first let me start with my system specs:c1: GTX 680 SC version GTX 680 NORMAL version 8 GB vengeance Ram asus p8z86 deluxe gen3 mobo 850w zelman PSU. 2600k i7 overclocked to 4.3 Ghz. water cooled playing games on zr2740w playing games on 2560x1440. ssd for gamming 2 tb hdd for storage i play fps games mostly BF3 on ultra setting which are as fallows : 1) every thing on ULTA. 2) AA off. 3) MSAA on x4 4) motion blur : OFF 5) vsync : off. 6) antisotopic filter: x16. 7) AA post : off. 8) AO: HBAO. now im getting LOW FPS when i play bf3 or any other games. my friend who has just 1 gtx670 has the same FPS as me even when i am on SLI :3eyes: today i tried playing on LOWEST setting still i only get 5 FPS improvement over the ultra :bang: evry thing low all AA off.. when i check my GPU load both cards are on 55ish % and never go high then that may be in the mid 60ths% some times...then y am i getting low FPS?? temps are normal. i overclocked my GPU to 4.3 GHz still no improvement...nvidia control panel is at normal setting. i have checked the cards they are in slots the rite way the sli bridge is fine and sli mode is on. just want to improve my FPS, please help. regards.
im sorry its 2600k..ill edit it. base-clock for the cards?? 1005 MHz for the normal card 1058 MHz for the SC card
i over clocked it manually fallowing the guide given on this from and others as well, the OC on the CPU is fine as its only using 75% of the load in game.
That should be good enough. How old is it? You try different drivers? Enable sli in the nvcp? I can completely Max out bf3 at 1080 with a minimum 60fps on my rig. You should do that no problem with sli 680. Ill let some Kepler owners chime in they may be more able to help you better.
well its like 4 months old, i have the UP to date drivers never tried old ones, yes its enabled in the NCP also in the EVGA tool both cards are synced, when i try playing with just one card the load is fine arounf 90ish%...and fps are around the same as on the SLI which is quite disturbing lol
ok so i tried it i got this result: Powered by Unigine Engine Heaven Benchmark v3.0 Basic FPS: 111.3 Scores: 2804 Min FPS: 39.9 Max FPS: 223.2 Hardware Binary: Windows 32bit Visual C++ 1600 Release Mar 7 2012 Operating system: Windows 7 (build 7601, Service Pack 1) 64bit CPU model: Intel(R) Core(TM) i7-2600K CPU @ 3.40GHz CPU flags: 3399MHz MMX SSE SSE2 SSE3 SSSE3 SSE41 SSE42 HTT GPU model: NVIDIA GeForce GTX 680 9.18.13.697 2048Mb Settings Render: direct3d11 Mode: 2560x1440 fullscreen Shaders: high Textures: high Filter: trilinear Anisotropy: 4x Occlusion: enabled Refraction: enabled Volumetric: enabled Tessellation: disabled Unigine Corp. © 2005-2012
What OS are you running? Windows 7? Have you tried a BIOS update for your P8Z68-V? EDIT: I see you're running Win7 64. For troubleshooting I would first remove the CPU overclock and run it at stock speed. That eliminates an overclocking issue. Secondly, I would keep an eye on your GPU temps. If your GPUs go past the ~80c threshold they'll start throttling back their clocks. I would DEFINITELY ensure you are running a more current BIOS for that board. I initially had 680 issues with my P8Z68 when I had it, and a BIOS issue did wonders for lots of things.
Amazingly, you neglected to actually specify how many frames per second you are getting, which would have been useful information for people with similar systems as yours. What is your VRAM usage%? BTW, just because you see GPU usage% at 55-60 doesn't mean anything is wrong, especially if you have vsync enabled. In my experience with SLI, many games never hit full utilization. As someone else suggested, run Heaven and check your utilization, both GPU's should be pegged at 99%. If not, something is wrong.
well i was getting some where from 50 to 70 fps even on lowest settings of bf3 and on ultra also the same....i have already dont a heaven test and have posted the results above if u would have seen em? both gpu's were at 99% with very good FPS lowerst being 40fps and higest being 223 FPS on 2560x1440 rez.... but saying all this i have found the solution to my problem. i taught i start from the bottom and start to troubleshoot every thing: i took every thing out from my pc and re connected every thing....uke2: re-installed my windows 7.... formatted all of my memory..ssd and Hdd. NO more overclocking for the CPU 2600k cause i dont think i have a bottle neck for now. updated my bios , since i found out i never updated and always had the one from the CD which came with the mobo :bang::bang::bang: then i re-installed the gtx680 drivers...made sure sli is synced....ect then i downloaded new origin and new game+the DLC. now my gpu usage on ultra and x2MSAA is like from 60 to 80 depending on the map and even goes 100+...so i dont know what fixed it but started from scratch did it, NOW my question is i have 8GB ram do i need 16GB RAm ?????
try flashing bios i have a p8z68 and had a lot of gtx 680 issues i had to actually use my 480 until i got the latest bios which magically fixed it. edit:motherboard bios not video bios.
I experience nearly the same thing on BF3... There's hardly any performance increase when lowering settings when SLi is enabled. 1920x1080 Ultra (4XMSAA + HABO) 85 FPS 1920x1080 Ultra (No MSAA or AO) 87 FPS 1920x1080 Lowest settings 119 FPS Compared to SLi disabled... 1920x1080 Ultra (4XMSAA + HBAO) 51 FPS 1920x1080 (0XMSAA or AO) 74 FPS 1920x1080 Lowest settings 107 FPS Disabling MSAA & AO without SLi show's a 23 FPS increase compared to the 3 FPS increase with SLi It resembles a CPU bottleneck, but higher CPU clocks don't help much (11 FPS increase at 4.6GHz vs stock). When forcing SGSSAA the FPS decrease is the same with SLi & non-SLi as if there isn't a CPU bottleneck. If there was a CPU bottleneck the performance drop with SGSSAA would be smaller with SLi. I thought thing's would be different at a higher res, but now...maybe not. When you get it sorted let me know... *edit* Never mind, I see you resolved the issue. (I too had just reformatted, going to re-install the game)
