NVLink Questions

[Hi P]

1.- Do motherboards that support SLI also support NVLink?

 

2.- Is it true that GeForce RTX may not support vRAM pooling through NVLink? (article below)

It seems like all sli boards will work fine.

 

What are you using nvlink for? If its for gaming, it won't use pooled ram, and that seems to be disabled on consumer cards.

I will get a single card, I was just thinking ahead in case I wanted to purchase a second RTX to pool the vRAM on 3D apps, do you think it's going to be possible?

If a mod gets created to overcome it, yeah.

For all intents and purposes the consumer NVLink (the one for RTX cards) is just like SLI bridge but with much higher bandwith and different name. It's still SLI so SLI ready mobos will support it.

 

You will notice that the NVLink bridge for RTX cards costs $80:

While the one for pro cards with vRAM pooling costs significantly more ($599)

They are NOT compatibile.

I don't think that means you can't do vRAM pooling with the consumer cards. You might just be more limited in what you can do if someone comes up with a mod.

What do you exactly mean by a "Mod"? (I'm curious)

 

Do you mean as if somehow applications made vRAM pooling possible?

Some one finds a way to mod the driver. It will won't aswell.

 

What 3d apps?

 

If you really need a 3d pro card, get a quadro, nvlink won't save you here.

Like Maya using Redshift, I just thought I could buy a card while having the option of pooling the memory with NVLink, but looks like that won't ne the case.
