A little help with ASRock x99 Extreme 4 problem

[jim1976]

Hi guys,

yesterday I added a second 980Ti on my mobo for 2 way SLi. I am using the x99 extreme4 as I said in the title and a 5820k.
My problem is that when I place the second gpu in pciex16 slot 3, this covers the only pci slot which is directly below it and I cannot use my ZxR card.

Now if I place the second gpu in pciex16 slot 5 down below I don't think it will work with 2 way SLi, or am I mistaken?

It's a huge problem since onboard audio cannot compare with my ZxR. Am I missing something obvious here in the mobo layout or is there any other alternative?

Thanks in advance for any help

says -
3 x PCI Express 3.0 x16 Slots (PCIE1 @ x16 mode; PCIE3 @ x16 mode; PCIE5 @ x8 mode)*

pcie3.0x8 will be fine.

I don't think there is an old PCI slot on that board?

PCI-E 1 and 3 only for 2 way SLI.

Put the sound card in slot 5? A 1X card should work in any slot.

@i7baby
Not working m8, just tried it with the long bridge connector and cannot enable sli..

@LTC8K6
I'll try to put it in slot 5 and check. Thanks for the help

edit *It WORKS now SLi is enabled and ZxR is working on PCIe slot 5 but I get less performance from my SLi system, though in GPUz it's still recognized as x8 for both GPUs

That's with a 5930K or 5960X. With a 5820K the last PCIe slot would only be x4, which isn't enough for SLI to work.

Any idea on how to deal with that?

Try setting the #5 link speed to 1X in the BIOS?

Nm the hinder of performance was my fault with a messed up o/c profile in Afterburner after I swapped cards and re-enabled SLi.
Everything seems to be working fine now thanks everyone for your help.
