Unigine Heaven 4 benchmark

Not very happy wiht my GTX1080ti SLI results. Could it be that using an old ribbon SLI bridge is causing me issues? Would a HB bridge make a difference?

With 2 cards you need to overclock the CPU as high as it will go for this bench.

A HB bridge will help in some benches/games too.

If you want your score to count for the scoreboard you need to post over the cobblestones.

6800k @ 4.2 gigabyte gaming g1 1080 sli

Scoreboard updated.

silly question notice you have a 6950x is it worth the money ???

For gaming a 7700k is better.

A 6950X is good for number crunching or running benches like the Futuremark ones.

For this bench (Heaven 4) a 6950X is a bit of a liability as they don't overclock like a 7700k can.

Ill stick with my 6800K for now then lol

No. HB SLI bridges are only intended for 4K gaming, and then only if you go over 60fps.

Surely my CPU being stock wouldn't make SLI enabled worse than SLI disabled in valley, something isn't 100% right here.

Cooper · 29 Mar 2017 at 12:27

Well I don't know what the issue is that your having but I do know that getting an HB SLi bridge isn't going to solve it because as I said they're only needed for extreme resolution gaming.

thermal throttling maybe, what pci-e link speed is gpu z showing for them ? could it be something as silly as wrong link speed in bios or in wrong slot ?

It can do.

Valley is the worst benchmark you can get when using 2 fast GPUs as it is a huge bottleneck.

Ace Modder · 29 Mar 2017 at 16:43

Thermal throttling isn't an issue, they are watercooled and are not breaking 40 degrees on the core.

As for the slots, I'm using slot 1 and slot 3, which is what my manual for my motherboard says to use, and thats what IU was using for my GTX 980 SLI fine. I have the OC-PEG connector plugged in aswell, which gives PCI-E extra powerr stability (mother board is X99-SCO Champion)

both cards are running at PCIe x16 3.0

No issues with the card setup that I can see. (this was running valley on loop)

Besty · 29 Mar 2017 at 16:53

Ace - run a firestrike physics only test and post the score.

zia · 29 Mar 2017 at 16:56

That gpu load is probably why score is low.
and its says in window mode?

Looks like Vsync

When I'm running that bench with a single 1080 Ti there's instances of where my gpu isn't at 99% usage simply because of the high framerate. Run this bench at 1440p or 4k and you'll see what sli can do

Smffy · 29 Mar 2017 at 17:52

There's not 99% though and there's 40%... potentially v/gsync or it's capping at 60frames in windowed. Shadowplay off also... seems like the GPU usage is low for that test though.

Ace Modder · 29 Mar 2017 at 18:31

That is at 3440x1440

Ace Modder · 29 Mar 2017 at 18:42

Just tested valley at 2560 x 1440 (max I can set my monitor is 3440x1440 but 21:9 isnt supported)

My cards didnt go above 65% load.
