Hello everyone.
 
I have a new rig, an Asrock Z390 Pro 4 mobo (I am thinking this mobo doesnt support sli? ), 32gb memory, I9 9700k, and 2 Zotac 2080 video cards.
I set the system up (it was already set up by ABS Pre-Configured system, since I bought a system already configured), then set up sli.
Well, I NEVER get the sli option under nvidia control panel > 3d  settings > 'Configure' surround/physx (which SHOULD include SLI if SLI is detected).
If it IS the mobo, does anyone remember that software sli solution? I know the cards are the same everything, as I used Zotac Firestorm to check the bin/vid (basically the card, and the bios of the card).
 
Any help is appreciated.

P.S.
Yes, I have contacted both Zotac and ABS, but they are slow, and I dont know if they know about that Software SLI, or if that even works on 2080's yet?

No, no m.2
And, yeah, I just used gpu-z and the 2nd card is being run at pciex16 @ x4 1.1 ?
WTD?
 
It should be running at x16, not x4.
:(
 
Sigh.
 
I put power management on 'prefer max performasnce', but that didnt do anything.
My mobo says 2x 16x pci-e 3.0 slots.
Nothing about x4, except the 1 x4 onboard and the 1 x1 onboard.
:(
 
And, gpu-z does show both cards as:
Device id: 10de-1e87-19da-3500
clocks: 1515 1750 1830
 
So, they are identical cards.

That's ASUS for you. Corrected
That Motherboard only Supports Only AMD Quad CrossFireX™ and CrossFireX™
Z390 Pro4 https://www.asrock.com/mb/Intel/Z390%20Pro4/index.asp

It took 4 Enables SLI in the NVIDIA Control Panel to finely work for me.

Do you have the NVLink SLI bridge installed between both cards?

Well, Asrock replied and said it only supports xfire and not sli.
What the duece is up with that ?
If it supports xfirwe, and has 2 x16 slots, why doesnt it support sli?

"Asrock replied and said it only supports xfire and not sli." Bummer

That's ASUS for you.

Asus boards are fine, he has an Asrock board.
My z370 Killer SLI/AC Asrock supports SLI, hard to believe that one does not suport SLI in this day and age.
You bought a pre-configured systems with two 2080 GPUs and it does not do SLI? I would get a refund

Corrected, thank you.
I was seeing I7 5930k watercooled-Asus Sabertooth X99- in his Signature.

No, I bought the system that said it had 2x 16x slots, and 1 2080 card, and I knew they used the same video card as mine I already had.
So, I put my card in with the already installed card.
They did not show what mobo was in the system, just that it had 2x 16 3.0 slots. It wasnt until I got it that I found out what mobo it had.
:(
 
I wonder WHY ABS put in an nvidia card in a mobo that only has xfire support though?
I hope I can get them to just exchange a mobo for me, to an sli one.
Its the only reason I bought from them and didnt do a REAL pre-configed system that I could ask for exact components. Well, that and it was on a pre-black friday sale, too good to pass up.
:(

Yeah, but I bought the thing pre-configged to save money, now I will end up losing money on it having to buy my own mobo.
Kinda hinkey that ABS puts on there that its a 2x 16x 3.0 mobo, but NOT that it only supports Xfire.
:(
 
And for the above person, I updated my sig to include the new system, not the old one. Thanks.

Thats a thought, except I have a G-Sync monitor.
Seems I can get a super duper similar mobo from asrock that JUST has the sli support, and everything else is the same, so I 'should' be able to just swap out the mobo and not have to mess with asny drivers.
The only thing is that ALL the Z390 I can find only have x8/x8 in sli, and thats everyone (except a SUPER expensive msi). Is that because of the chipset?
Will 2 2080's saturate the 2 x8/x8 lanes?
 
I dont want to get a new mobo and have micro-stuttering because its saturating the pcie lanes.
:(

Good to hear it all worked out...

Dont know what I am going to do with it.
Are you interested ?
PM me if so.
 
(BTW, love your sig. I carry a SOG Spec Elite I)

LOL NP.
Finally got the new mobo in and running, and I have to say:
WOW!!!
2 2080's in SLI FINALLY give me the gaming I am looking for.
Dips only go down 'maybe' 20 fps in Shadow of the Tomb Raider (only once went into the 90's, and that was 97 IIRC). AND the CPU and GPU were almost in-line with each other this time!
Other games bench and run at over 200 fps now (they were fine before, at 100's, but did those dips down like 40 fps, and the stutter is just terrible trying to game like that. But, no more! SLI absolutely rocks with the 2080's.
I have yet to try Vermintide 2, but it ran at 113 and lower also, so should be really nice and tight now. EDIT: Dipped to 89 one time, dang it! Thought I would get away with upped 90's and above, but nope, that many rats at one time, all that AI, sigh. :)
Strange Brigade was all 200's and above.
Snipe Elite 4 got down to 167, in an area that had lots and lots of shadows, with far away mountains and buildings, 6 enemies, and water (a lake). The rest of the times it was stable at 189-210's. But, I did go from 4x AA to 16x, and that had a weird effect on the game (or SLI did): When there was water, the game got choppish-ey. Only on standing water, like puddles. Guess it is the reflections from the puddles and high AA doing that or something?
Ghost Recon Wildlands finally able to max everything. Lowest fps was 82.
:D
 
Oh, and I am an 'EVGA' user AGAIN, since I had to put my EVGA 1600W psu in just to run this beast! (the 750 didnt really like running with sli (It was a 'cougar' brand and would have gotten replaced anyway), so in went the 1600.
 
I have some pics (I wanted all blue, but the front fans for some reason are Red ONLY, and dont do the whole color thing, so everything blue with 3 front fans at red dod NOT look good, lol).
 
@Bill:
Nice, I USED to have over 300 knives and swords, but had to sell almost all of them when I lost my job, and I have been collecting since I was, what, 15?
Maybe I will share a pic of an old old old computer room with you, that had a few of my knives and swords on display. ;)
