Sextuple SLI Motherboard x8/x8/x8/x8/x8/x8

Hi Tech Tips

 

After many fail googles searches here I am after a very long time.

 

What I am looking for is a Motherboard CPU combination to run 3 DUAL SLI on one board.

 

 x16/x8/x8/x8/x8/x8 or  x8/x8/x8/x8/x8/x8

 

All cards need to run at minimum x8

I don't think that's going to exist.

What are you trying to do? If you need that much GPU performance, a Quadro or two is probably going to be better and better priced.

There is a good amount of server and workstation board that can do this, like lots of boards in the asus ws line like the Pro WS WRX80E-SAGE. 

 

But what are you doing? Software doesn't support this, and you would need single slot cards for this config. Or get something like a 4u gpu server.

 

What workloads are you using?

That's 48 lanes, go with either threadripper, xeon-w or some other server platform.

One can get away with raisers. I like to assume that people the ask about such setups are not stupid and aren't looking into using that for games, but rather have some specific software usage in mind (although that mention of "SLI" is worriesome).

This is for a mining rig on a 3060. 

3060 has the best return out of the modern cards for $$ and power consumption.

 

Issue with the 3060 for max hash performance is only possible at x8

So you're not looking for SLI. As far as I know, the only 3xxx that actually supports SLI is the 3090. Having pairs of GPUS =/= SLI. 

What you're looking for won't be cost effective. About the cheapest way I can think to do it would be with multiple used Optiplexs and then find some way to add a PSU that would handle the 3060s. Short of that, you're looking at the motherboard mentioned above for $1000, then the CPU to go in it, and risers to make all the GPUs actually fit. So 6 of these, and this is the cheapest CPU that would work in that motherboard. https://www.techpowerup.com/cpu-specs/ryzen-threadripper-pro-3945wx.c2317

The 10900X from Intel has 48 lanes, but that doesn't leave any left over for the boot drive. The 9900x has 44.

Pro WS WRX80E-SAGE 

This board will do it.

 

So in the end not worth it better off with a dual 3090 mining rig which can run on a more basic cpu setup
