    Posted: 06 Apr 2022 at 4:24am
In the Aventum X top level Intel/nVidia configurator it offers the Core i9-12900KS ptocessor which doiesn't support 2 GPU's in NVLink.
Why no 2 separate GPU's, i.e..not conjoined?
Also any idea when that particular configuration will support liquid cooling blocks for 2  GPU's?

Thanks.

The Configurator is not the only builds possible, just the most commonly probable. Your questions are for Digital Storm to advise you on.

Yes, that's probably the case, thanks.

You can select dual NVLINK graphics cards, but only if you choose RTX 3090's, and also upgrade to the ASUS ROG Maximus Z690 Extreme motherboard. Lesser models of the RTX GPU series don't support NVLINK.

It looks like the configurator won't let you choose liquid cooling for 2 cards though.

Here's a configuration that shows two NVLINK cards selected:

https://www.digitalstorm.com/configurator.asp?id=4492458
Velox, Intel Core i9 11900K, ASUS ROG Maximus XIII Hero
32GB RAM, 1TB Samsung 980 Pro NVME
RTX 4090, 38" Ultrawide LG-38GL950G
Noctua NH-D15S cooler and NF-A14 fans, Corsair AX1600i PSU

Question though...why bother? NVLink looks good on paper, yet most gaming developers do not build their games to support it. It is not adopted across the board and is essentially a waste if you are already investing into the 3000 RTX cards.

While it is better than the old SLI, until game devs adopt and support it whole-heartedly, it is literally a waste of money. As far as workstations are concerned, pretty much the same thing. In many cases, software isn't even built to utilize multiple GPUs - so having support for NVLink just really doesn't matter.

Invest your cash in other upgrades IMHO.

Yeah, that's a good point.

I used to be a huge fan of SLI gaming, but it's just not worth it anymore. Most games don't support it, and even the ones that do frequently have graphical glitches. NVIDIA has been deprioritizing SLI for a few years now, and their mainstream cards no longer support it.

RIP SLI.

I also used to be a diehard sli believer. I found happiness in single gpu systems after I got my 2x2080Ti and had a lot of issues that went away when I took one out (of course the gpus of today can go solo and do a lot).  Now I have only one gpu in my systems.

If you are into computing vis-a-vis gaming, then having the power of gpus combined with NVLink are a no brainer. Note that the top NVIDIA cards (3090s and 3090Tis) are NVLink capable.

With the launch of the 4090, NVLink is dead.

The Z690 Extreme is the only consumer motherboard on the market with an SLI key injected, allowing SLI to be enabled.

The rest of the motherboards on the market, consumer/prosumer, no SLI keys injected.

There are certain configurations where we contact a customer to let them know we won't be supplying the bridge to their order, thus also refunding them the cost of the bridge.
