Sli says its enabled but shows no improvement

[Papap28]

I have 2 gpus installed and it says sli is enabled but every time I fire up a game like gta v or rainbow 6 the fps won't get above 30 or 40 on 4K ultra. I thought maybe it's normal but then I checked benchmarks and saw performance for those games in sli should be SIGNIFICANTLY better. So I ran ungine valley with sli both enabled and disabled and got the exact same score. What's going wrong with my system?

Whats your full specs?

Could be that something else in the system is holding back performance.

What is your motherboard, and what GPUs are you using?

I7 6850k
Asus rpg swift x99 gaming mobo
2 evga gtx 1080 ftw

I doubt it's to do with hardware if everything is running as it should, pretty much everything is brand new

Just so we can be sure:

1) Sli bridge attached?
2) Sli enabled in Nvidia control panel?
3) Latest drivers from nvidia.com?

Yes, yes and yes. I have the bridge that came with my motherboard, in the control panel it says sli is enabled and I have the latest drivers but for some reason the performance is still poor

Can you monitor the GPU load of both GPUs when running a benchmark, MSI afterburner is good for this.

Also check CPU Clockspeed / temperatures / load%.

i ran the benchmark for gta 5, gpu's were pretty much <95% the whole time, clock speeds were normal, temps were both pretty much 70's, which all seems normal to me. as for cpu, idk much about that stuff, but i had usage testing and it was in the 20-30% range pretty much the entire time. interestingly, i have 32gb of ram but only 10gb was being utilized during the test, 11 at most. again, im a bit of a noob and idk much about this stuff but could that problematic?

Both gpus were hitting 95% usage? that sounds like its working tbh.

ikr? but tbh my benchmarks were very poor compared to other reviews. and i've seen videos on youtube and stuff of people maxing out 4k settings with 2 1080's and they're getting like 100fps. is the fact that im only using a third of my ram normal?

 

[RobCrezz]

Yeah thats pretty normal to only use that amount of ram.

Check you are using comparable settings. Also make sure you dont have vsync or any FPS cap enabled.

i dont have vsync enabled and idk but im pretty certain i dont have an fps cap enabled (not that i would know how to check tbh). in menus my counter reads like 200 fps so i doubt i have a cap

Try an benchmark tool like Unigine Valley/Heaven, so you can compare your scores directly with other people (make sure you use the same preset/settings).

one thing idk is if my bios is up to date. sorry if this is a stupid question, but do u know how to update? hahaha

There should be a utility you can download from the maker and it will check your version against the newest version, and update it if you want.

do you think it makes a difference because im checking benchmarks for gta on a single FE card and its pretty much the same as my "sli" lol
