First Computer Build second SLI 980 doing nothing?

[DeptiOG]

Hi,

   I have a 1000w PSU and I have entered all my parts into a PSU calculator and I don't exceed 1000w I sit at around 840 max. Anyways, when I start my computer both my graphics cards light up (Two 980ti's). But when windows loads my second graphics card dims. When I play an SLI enabled game, there is still no load on the second GPU. The GPUs never balance any load. This is my first PC build ever. What am I doing wrong?

 

ps MSI afterburner sees both graphics cards, but when I scroll over my Nvidia GPU activity monitor it says my second card is inactive.. how do I make it active?

 

I really appreciate all the help I can get as this is my first build ever and invested a lot into this, I want to get my second graphics card up and active asap for some pwning! Thanks!!!

Do you have the sli bridge plugged in?

Also what is your motherboard?

You need one that actually supports sli.

What motherboard do you have? Maybe there is an issue with the PCI?

And also, 2 GTX 980ti's? What games are you planning on playing?

1 GTX 980ti can handle 4k

I beg to differ, got SLI 980ti overclocked and still have to turn settings down at 4k (medium to high, modified).

I would have picked a GTX titan X.

Hi yes SLI bridge is firmly connected. Asus Maximus Hero VIII Republic of Gamers motherboard.

 

When I play SLI enabled games such as Crysis I don't see any GPU split activity. If I load ten applications all ten show up on the first card.

 

I checked my motherboard box says "Nvidia SLI ready"

Does it matter which part of the chip the bridge is plugged into? I put the bridge on the further of the two chip openings (sorry dont know what to call these) should I have done it on the two on the inside of those?

Did you enable SLI in the Nvidia control panel?

Ding ding ding

open nvdia control panle go to Sli 

click set to max performance under the Sli tab and click apply 

it's off by default

Thanks for the replies all but still nothing. SLI has been enabled and it is set to max performance. don't know what PhysX but it seems to be using my second GPU.

 

shouldn't the loads split on SLI enabled games or will I see the load all on one card?

Its very simple to test, find a benchmark and try with SLI enabled and disabled.

If it remains the same, you got a problem, if it does go up with SLI, everything is fine.

980Ti has same performance as Titan X, only difference is VRAM.

I am doing a benchmark now with 3dmark Fire Strike Extreme benchmark. 

 

with SLI enabled i got just below a 15k score 

 

disabled I got 4.5k lol... i def think SLI was working.. weird!

You said physx by default took the second card to be the physx card, well the set the physx processor to cpu and then you will be good to go.
