Gigabyte Z87X-OC

What slot have you got the GPUs installed to??

1 x PCI Express x16 slot, running at x16 (PCIEX16)
* For optimum performance, if only one expansion card is to be installed, be sure to install it in the PCIEX16 slot.

1 x PCI Express x16 slot, running at x8 (PCIEX8)
* The PCIEX8 slot shares bandwidth with the PCIEX16 slot. It will operate at up to x8 mode when the PCIEX16 is populated.

2 x PCI Express x16 slots, running at x4 (PCIEX4_1, PCIEX4_2)
* The PCIEX4_1 slot shares bandwidth with the PCIEX16 and PCIEX8 slots. When it is populated, the PCIEX16 slot will operate at up to x8 mode and the PCIEX8 slot will operate at up to x4 mode.
* When installing a x8 or above card in the PCIEX4_1 slot, make sure to set PCIE Slot Configuration in BIOS Setup to x4. (Refer to Chapter 2, "BIOS Setup," "Peripherals," for more information.)
(The PCIEX16, PCIEX8, and PCIEX4_1 slots conform to PCI Express 3.0 standard.)

slots 1 and 3, just tried tomb raider, black screen froze pc, then did hitman and got 10 fps increase from 1 card on average and 2 on max. Then I run the benchmark again and it hitches to a minimum of 1. I'll do some tests with MSI afterburner next.

Have you set the PCI speed in BIOS for that slot to 4x? You should have the GPUs in 1 and 2 for the best performance with this MB.

I'll double check on that, using it in 1 and 3 for airflow because the vapour-x cards are pretty big.

Manually set it to x4, had better performance on 1st run but 2nd run hitching and barely loaded with minimum 1fps.

I doubt it's my motherboard since before I ran sli 970s.

Am lost then sorry mate..

Looking at the manual for the board it would appear that slot referred to as PCIEX8 is infact the 3rd slot. It should be possible to run at X8 in slots 1 and 3 simultaneously.

What happens if when running a game you press Alt+Enter, wait a few seconds then press it again?

I'll try that now with a few games

You sir are correct.

jwilliamson47 · 15 Feb 2015 at 21:35

Hmm, seems to be better in-game than the benchmarks via the menu , eg sleeping dogs etc. I'll keep trying.

LtMatt · 15 Feb 2015 at 21:39

I think it might be time for a 'How Well Does Crossfire Scale' thread covering performance from one gpu, to two gpu's to four gpus. Sounds like a fun little project!

jwilliamson47 · 15 Feb 2015 at 21:40

Decided to reinstall the driver, and now it does nothing when saying "detecting graphics hardware" eurgh.

Ah, managed to get the driver to install.

I'll do gaming and see how it goes, I'm sure it's an issue that can be fixed

jwilliamson47 · 15 Feb 2015 at 22:19

Tried metro, runs nicely

Were you previously running in Windowed mode sir?

Nope! Here's the thing, it seems the benchmarks are running poorly but the games are running pretty nicely (Dying Light is a mess on crossfire, but I had the same issues on SLI). I'm going to download about 20 demanding games and see how it all runs.

Perhaps it was just a weird bug!

Not the best picture but it shows about 85fps at 1440p maxed without SSAA. Temps are superb for 2 cards.

Yes the game developer has fixed some issues with the game affecting multi gpu setups and it's running well for me now. I've also seen the new drivers in action with an improved Dying Light Crossfire profile and it was working well on QuadFire too at 4k.

Improved ? With the Omega driver my crossfire doesn't work when i play Dight Light...

And yes the new patch improved the stability of the framerate but i'm still at 30-40 fps outside in the city. It's not very good comparing to a GTX970. A friend of mine is running the game at 60fps minimum with its GTX970. And what do you mean when you sad it's running well for you ? 30fps ? 60fps ?

Hi all,

Just looking for a little help regarding a first AMD install please

Basically, after much pondering i've gone for a 290x over the 970 and have been reading in various places that when uninstalling the previous drivers you need more than a simple "device manager" uninstall, as this could cause problems with the new ones.

Now i've always had Nividia before so this will be the first time i'm "switching sides" so to speak, so I was hoping if someone could please point me towards the right kind of driver remover to make sure that all my previous stuff is completely gone before installing the 290x?

Any help greatly appreciated, thanks.
