NVLink RTX2070 super

Hi there,
I've tried searching for this info. But all info about this seems to be dated. So I'm hoping someone could give me a clear answer.
I currently have an Nvidia RTX 2070 super in my pc. It supports NVLink.
Simple question. Does rendering in DAZ Studio with the iRay renderer give me memory pooling with NVLink?
So will I have 16 gb's of vram available when I NVLink 2 of those cards together?
Hope someone knows the answer to this.

Not as far as I ama ware - and I thought the nVlink branding was new for Ampere.
If you have two identical cards, yes. Although only for textures, geometry is not pooled.
The possibility of joining two with NVLink was the reason I bought one in June 2020, but before I was able to buy the second one, they vanished from the stores.
This may help to answer some questions although it is an old article.. https://www.pugetsystems.com/labs/articles/NVLink-on-NVIDIA-GeForce-RTX-2080-2080-Ti-in-Windows-10-1253/
@Perttia Hmm but if only Textures can be pooled. Wouldn't it be better to just stick 2 of those cards in my pc. Use 1 for my screen and preview iray render. And the other on dedicated for the final render only (My current card has 3.5gb of vram used before I start rendering a scene. Adding a second card that way would net me 3.5gb at least right?)
Unless you go crazy with SubD, the VRAM usage of geometry isn't usually the problem, but with textures the 'trend' is going up all the time, even if not taking in to account the added effect of badly done UV mapping.
If you are not NVLinking the cards, your usable VRAM for Iray rendering will be 8GB minus the 3.5GB's
I solved the 'problem' by buying a 3060 12GB some weeks ago, didn't speed up the rendering much, but almost doubled the amount of available VRAM for Iray rendering
If you want to hold out a little longer the next gen cards might increase VRAM capacities. Even if they do not, they should push outgoing generations down in price, assuming the market doesn't explode again. Once the 4070 comes out, the 2070 with be two generations old and bottom tier 4050 cards should match or beat it in speed. The 3060 should drop in price as well, though its 12GB may prop it up a little, most gamers do not care about the 3060's VRAM, they only care about the performance which the 3060 is lacking. Gamers prefer the 3060ti.
We are probably just a few months away from the 4000 series launch. Some rumors say the 4070 will have 12GB, some say it will have 16, either way it will have more than past models. I am leaning towards 12, but 16 would be awesome. The 4080 is supposedly getting 16.
These are only rumors. But the 3000 series turns 2 years old this year, so we are logically due for new cards very soon.
...wondering when Nvida will push Maxwell completely out for Iray when the 40xx series arrives.
That is kind of a bummer. But technology has moved so fast that it really is time when it comes to Iray. But Maxwell might hang on a little longer thanks to gaming. The gaming side still has a lot of Maxwell cards out there. The 970 and 960 are currently ranked #26 and #27 in the Steam hardware survey, with both very close to 1% of the user base. You have to consider the user base is well over 100+ million people, so that is easily a couple million of just those 2 models.
To put that in perspective, those easily out pace the newer 1080ti, 2080ti, 2080 Super, 3080ti, 3090 and 1650 Super. These cards listed are not even close. So as long as those Maxwell cards stay reasonably popular, Nvidia will hesitate to pull them. Kepler cards are pretty much wiped off the list. I only see a few, and they are near the bottom of list around #86 with the 660 and 760 at just 0.21% and 0.20%. Very interesting that the higher end ones are totally gone, not even the once popular 670. The list shows over 100, with the last one be at 0.15%.
The real question is what will Nvidia do with Pascal? The 1060 is STILL the most popular GPU on the planet according to Steam with 6.94% share. It is unquestionably the best selling GPU of all time, and that is kind of haunting Nvidia now. Nvidia and AMD have both ignored the low end for so long, that 1060 owners are slow to upgrade. Without anything decent around $200 (the AMD 6500XT is not decent), who knows how long the 1060 users will hold out. The 1060 is still the defacto standard that many PC games optimize for. Honestly, the popularity of the 1060 is holding the industry back at this point because of this. The 4000 series might finally make something happen. The performance jump next generation between both AMD and Nvidia might finally be the push that changes things. If the 4070 is beating a 3090, think of how strong the 4060 and 4050 could be. The 1060, as well as any Maxwell, will look comically weak next to them.
At any rate, the Steam survey is probably the best guide for when they pull the plug. While gaming is different from Iray, I don't think they would end one without the other. They would just end driver support, and that's that.
Gaming aside, looking at DS and Iray... Even if Nvidia kept supporting the older cards, the amount of VRAM on them will either make them completely useless or severly lacking (exept the ones originally bought by selling a kidney or two)...
I built my current rig some six years ago, originally with a GTX 960 4GB. At the time even 4GB's of VRAM was a lot, but 3-4 years later, I had to double the VRAM with an RTX 2070 Super to be able to do anything and now added another 4GB's with an RTX 3060 12GB...
Well, yes, for sure. Only the 980ti had 6gb, while most others only had 4. The Titan Maxwell rocked 12gb, and there could be a number of them out there thanks to the used market.
That will indeed be another issue with Pascal when its time comes. The 1070 and 1080 packed 8gb and that has been standard since, so it has enough VRAM to remain relevant, along with its popularity. Pascal is basically Nvidia's Windows 7. They have been dealing with its shadow ever since. After all, even they admit this, during the Ampere announcement, Jenson Huang said it was now "safe for Pascal owners to upgrade". Clearly they want the Pascal hold overs to upgrade. Instead, 2020 happened and miners took over.
I am concerned that miners will make a run at the 4000 series when it launches. But this is totally up in the air. Mining has crashed, Ether is finally making its proof of stake move happen, and no alt coin seems to be ready to take the mantle Ether is about to leave behind. But this down turn will not last forever, just like the mining boom itself. It goes in cycles. So it is absolutely vital to watch that market if you have any hardware plans. If crypto starts rebounding, you might want to hasten plans buying a GPU.
