Dual GPU Quad SLI

[lilshaney]

Hi,

 

I am about to buy a motherboard that says it supports 3-way SLI... I have 2x GTX 690 which is a dual GPU so effectively 4 GPUs will they be supported?

 

Thanks,

 

Shane.

what motherboard?

Yes, if I remember correctly, it's been so long since the last time a dual GPU card was targeted at gamers.

 

Of course you need a pretty beefy PSU

It depends, if your motherboard see it as two GPUs. And the SLI part of one Dual-Gpu is done by the GPU itself it should work. If the motherboard sees it as four independent GPU no it won't work.

Yes, the dual GPU cards will work just fine.

But to confirm that we need the Motherboards.

It'll work. It's no different than putting the single 690 into a motherboard that doesn't support SLI. The dual-GPU cards are designed for people who want to cram more power into a smaller form factor.

Yes, as perhaps the largest proponent of dual-GPU parts, yes. Have a good time with them!

Had forgotten about you and your Titan X + Titan Z masterpiece

Thanks, wasn't sure it worked that way. But now I know. :-)

Damn. Talk about power

might be wrong- but I don't think so. Unless the manufacturer is referring to the 3 gpu slots only. But I think dual gpus are already in sli. So effectively two of them would be 4 way? 

 

Id do more research on your own while taking into account the replies here 

It's functionally four-way, but the communication is done between the GPUs on the boards, and a single SLI finger.

Thanks for the help guys! I will probably have to make a new thread but I have another question about the motherboard and CPU... I have an i7 5930K CPU and I know this motherboard supports 128GB of DDR4 RAM but the Intel website says my CPU only supports 64GB of DDR4 RAM... Is 128GB compatible?

Jesus you quoted me fast  realized I was wrong right after I posted and changed my answer ?

In order to use 128GB of RAM, you would need a better CPU.

It's better to reiterate something anyway as it helps drive it home.

Out or curiosity what 2011-V3 CPU supports 128GB of RAM? Or is it just Xeons?

Ahhh thanks! Yeah a bit out of my price range... One final question what is the best configuration 4*16 or 8*8 for the RAM modules?

Are you looking to upgrade your motherboard or something?

No I'm building a new PC and just haven't bought the motherboard and RAM yet:)

[jjohnthedon1]

Yes because u don't need a sli board to use a dual card because it's only on one slot

Well, and I can justify them as working, as even on my Non-SLI workstation motherboard (which REALLY DOESNT support SLI, as Nvidia makes companies pay extra for that functionality), my dual GPU card does SLI properly.

How do all 3 run together ? 

Is it good ? 

Fps are u pushing !!! 

It just sounds insane
