Seems like nvidia is giving different answers to different people, i know few people who were told by nvidia that a6000 bridge will work with 3090 as long as it can fit the card and cooler isnt in the way which shouldnt be problem when you watercool
And some people were told that it wont work due to size, which again i think will be solved by waterblocks, i guess we wont know until someone tests it.....

i'm getting the same sense about this.   i picked up the aorus 4 slot nvlink and am going to try and disassemble it to hopefully find a ribbon inside and maybe use as a 3 slot.. lol.  desperate times call for desperate measures.   

looks like the 6800xt and 6900xt's crossfire.   might switch to AMD due to this.  if i can get my hands on a couple of the 6800xt's in particular, i'm going to buy them and compare to a single 3090 in game performance.   if they do better, for less, i think it'll make the decision very easy to go away from NVidia based GPUs.    pretty unhappy with the stupidity in not supplying 3 slot nvlinks. 

Please let us know if  its a ribbon that can be used as 3 slot. Thanks.
 

 
i took it apart and unfortunately, it's not a ribbon.. it's a hard "pcb."   bummed about it.

it did come apart pretty easily ( just snaps together ) and went back together as easily.

Being that no one offers a 3 slot bridge I’m pretty sure everyone uses the internals of the nvidia bridge and puts their own spin on it with the housing. Saying that you’re never buying from evga doesn’t make sense if there’s not a single company making 3 slot bridges.

i appreciate your input and opinion.. however, i disagree with you.    if something like 90% of all consumer motherboards are 3 slot designs, and when put on water, the 3090s are now either 2 slot or ( hydro copper version as example ) single slot designs, thus making it not only appropriate, but necessary to have 3 slot nvlink bridges available, then for me to say that since EVGA offers the card in this manner but doesn't make it possible for me to use 2 cards in NVLink on ANY z490 ( including evga z490 dark boards... ) or x570 board, that i WILL NO LONGER PURCHASE FROM EVGA... then i would say it's a very fair statement/demand/expectation at this point.    

for me to also say that since AMD offers crossfire still on their 6800xt and 6900xt and that they can be used in multi-card setups.. and potentially offering the same if not better potential performance due to how crossfire works, at a lower price now ( 2 6800xt = about $1300 ) it would make sense to maybe leave NVidia entirely since they don't support their own features.   
 
As a consumer i have the right to spend my money where i deem fit and if a company is operating in a way that is not consumer friendly, then i simply wont give them my money anymore.   

If you said you would no longer buy nvidia then that would make way more sense than a single aib. I may be wrong but I'm fairly certain that companies would offer a 3 slot if they could. This is literally the first generation I'm not doing sli because of a lack of 3 slot, that and lack of driver based sli support. But honestly even without driver based sli support I'd still probably run sli kingpins exclusively for 3dmark but I'm not using riser cables and a clonky setup for benchmarking. I feel your pain.

Contacted support again just to be sure. Here is the script:
 
 Inamdar: Hi, my name is Inamdar. How may I help you?
 Inamdar: Hello,
 Kalverstukas.007: Hi Inamdar. I have two questions:
  Kalverstukas.007 : 1. Is NVIDIA RTX A6000 (Ampere) NVLINK Bridge compatible with RTX 3090 cards?
  Kalverstukas.007 : 2. Where can I order/buy A6000 NVLINK Bridge from in the US?
  Kalverstukas.007 : Thanks!
 Inamdar: Sure, I'll be glad to help you.
 Inamdar: Please allow me a moment. Let me check.
  Kalverstukas.007 : OK
 Inamdar: Thank you for your patience. Sorry NVIDIA RTX A6000 (Ampere) NVLINK Bridge will not compatible with RTX 3090 cards. So you can't use the bridge with RTX 30 series cards.
  Kalverstukas.007 : I have previously received response from your support as well as your partner's support (PNY) that it is:
  Kalverstukas.007 :

Hi,
it is compatible with the rtx 3090

Hi! Will NVIDIA RTX A6000 nvlink bridge be compatible with RTX 3090 cards? Thanks!
 Inamdar: Sorry, it doesn't works.  It wont work, 3090 Nvlink is a 4 slot bridge, and you can only see 2 and 3 slot bridges for the Quadro, the 3090 is a bigger card and doesn't have the same spacing as normal dual slot cards.
  Kalverstukas.007 : there are dual slot 3090s on the market. What is the problem about the size? The matter of question is actually that there are only 4-slot consumer bridges while many cards and motherboards have 2-3 slot spacing
  Kalverstukas.007 : there are even single slot 3090s on the market (e.g. EVGA Hydro Copper series or Gigabyte Turbo series with a single row I/O ports)
 Inamdar: Sorry, please allow me a moment. Let me check.
 Inamdar: Thank you for your patience. I will have check this case with concerned team and update you through email. Sorry for the inconvenience caused.
  Kalverstukas.007 : Thank you. No problem. This is an important question. There is only a 4-slot consumer 3090 NVlink bridge, but lots of cards with 2- and 3-slot spacing, thus 2- and 3-slot bridge is needed. That is why I want to ask if the RTX A6000 NVLINK bridge would be hardware compatible. The issue with the "size" that you have mentioned is not valid, since the graphics card is basically a PCB inserted into PCI-E slot, so this is only a matter of PCIE slot spacing
 Inamdar: i understand. I will check and update you on priority basis.
 
Update will be posted as soon as email is received.

The main reason why 3-slot is not available is that then Nvidia technically would say that you can do it and it works. And of course it works in water cooling system and even air cooling if you have enough air flow but there would be still so many people who would burn their cards and then would cry to NVIDIA that because 3-slot is available, this should not happen. Nvidia has shared nvlink design for partners and said that no 3-slot links. You can get that A6000 2-slot link from multiple place (because 2-slot not fit in 3090FE) but not 3-slot. Im pretty sure we never will see 3-slot in market, Nvidia partners can install those in complete systems but not sell out. There seems to be even some protection ship in link so not so easy to reverse engineer it. Obviously it is fairly easy to create two adapters which change card spacing and then use 4-slot but is this so huge problem that some1 will do it, I don't know. 

I sent email in some companies who has 2-slot bridge in stock and asked if they are getting 3-slot bridges. They said that so far NVIDIA hasn't shared the part number for the 3-slot so it is not orderable but they try to request it.

So far dihuni replied and told they dont have that code but will request it. You can google 900-53651-0000-000 so you see what companies are selling 2-slot bridges. 

I forgot i had this email from PNY with part numbers since november:
 
We offer the NVLink bridge with the part number below:

gonna see if i can find someone with more "electrical" expertise and see if there is a way to cut it down/shorten it and use this... lol  i'll update if it's possible. 

I doubt it could be cut down, i think there are too many traces, but of course there are still quadro bridges but no one has tested it so far, i would if i recived my two cards yet but since im in EU my PC is still sitting without a single GPU and am still on evga queue waiting for my cards :(

I have contacted William George, who has made great review of Nvlink Bridges 2 years ago, would he update his compatibity matrix.

The quote:
"I do want to do a new NVLink chart like that - or maybe add to the existing one, but I think that might get too large / complicated / confusing. However, in order to do so we need to wait for the A6000 to be available, and to have bridges designed for it in-house so that I can test them on pairs of both cards (A6000 and RTX 3090). I'm anxiously awaiting the A6000 for other stuff as well :)"

PNY sent email today said RTX A6000 3 slot NVlink should be ready for sale in 2 to 3 weeks. Looks like I can keep the 3 slot motherboards.

please post link when you see it available.  

Still waiting for the Kingpin to become available!

3 slot rtx

BLACK-ROCK
3 slot rtx

Thats old bridge for 20 series.
Gigabyte, Nvidia and EVGA have 4 slot NVLink for 3090 all other brands dont have their bridges released.

Hello guys, after a couple of weeks I'm still waiting a bridge in 3 slots. I'm following this thread and tank you to keep it updated.
I'm a CG artist and want my 48gb pool memory on my system for 3D application and more.
I don't really understand why manufacturer don't sell 3 slots bridges. A lots of motherboard cards have 3 slots space. You can buy a MSI Godlike, it's the only motherboard available in 4 slots space ;). I tried Asus, Gigabyte, Evga, no plans for a 3 slots bridge lol. 
Count on me in for a bulk order if necessary.

FYI - if anyone is interested, SabrePC has the Nvidia 2-slot adapters in stock.
