Asus WS X570-ACE MB - Is pairing this board with 3 2080 ti a good idea?

Yeah but there is your bottleneck.
If you build a render system with three 2080ti´s,
then you also want as fast as possible nvme drives.
And sure the the first m.2 gets it’s own 4x dedicated lanes.
But you likely would wanne use as much fast nvme storage as possible.
Or in other words, more then one highspeed nvme drive.

Also yeah pci-e power might be a concern as well indeed.

So yeah in my opinion HEDT would still be the way to go here.

aBav… You have just made things a little more interesting for making the ACE an option still. The last issue for me is the possible PCIe power; I might consider under volting and clocking the cards just a bit.

MisteryAngel, I’m not rendering animations. I want to render single 6k or 8k frames. All my 3D projects and files will be stored on a nas to prevent file lost. I will connect by either ethernet (I think it’s 2.5gbps maybe 1gbps) or usb.

I’ve just joined this site a few day ago and so far its been great! Thank you all for a the help! :smiley:

Yes i understand that.
But you are not rendering directly to the nas i suppose?
So yeah, that’´s what i mean by the limitations of a mainstream platform.
I would suppose you prefer to use more then one super fast nvme drive.
And then you pretty much run out of lanes.
Unless the render output files aren’t that big,
and you put them right on the nas when finished.
Then you could eventually work with just one nvme ssd.

According to this review a partner-model 2080 TI draws around 48 Watts from the PCIe slot, well within spec.

To be sure you could just write ASUS a technical support request asking about your intended configuration.

Right now my gut feeling would tell me it’s going to be OK - if the Pro WS X570-Ace meets your storage I/O needs.

Yeah i agree on that, it’s likely going to be fine.
Would have been a different story when we talked about,
reference RX480’s there. :slight_smile:

I’m planing to render straight to the nas to keep everything in one place. Hopefully the raid saves me from any misfortunes.

I’ll still keep the I/O limitations in mind, it’s easy to miscalculate storage or add in card needs.

In that case, it might work for ya. :slight_smile:

Still i recomend to consider going HEDT for workloads like this.
But of course i cannot look into your wallet haha.

That’s a fare point.

I might go HEDT if the price is right.

Just out of curiousity: Are there any benchmarks how the actual used PCIe bandwith affects a GPU’s performance when using them for the rendering purposes you detailed?

The very small differences make me wonder how an X570/3950X system with 7 GPUs @ PCIe 3.0/4.0 x4 would perform (PCIe bifurcation and a contraption with active risers).

Wonder if you could use one of those funky mining boards with like 12 pcie slots

I’m planing to mostly use LuxCoreRender which uses Open CL and will likely use other GPU Renders as well. 3.0 PCIe 4x will work for Lux at a similar speeds to 16x according to one of Lux’s Developers:

If I were to bifurcate, the only closed case option to support more that 4 gpu’s I know of is the Rosswill GPU miner… That’s a maybe. Also, If I bifurcate won’t that increase the power draw on the PCIe slot?

Gold_Two
Power usage bill for 12 gpu’s is not an option me lol! Maybe 4 or 5, calm down man lol!

You can for sure use at least 6 GPUs on the WS Pro X570-Ace in up to PCI 4.0 x4 mode:

  • The large PCIe x16 slot supports bifurcation to x4/x4/x4/x4 (CPU lanes)
  • M2_1 is x4 also from the CPU
  • The lower PCIe x8 slot by the chipset can take a sixth GPU (don’t know if it also supports bifurcation to x4/x4, then you would have 7 GPUs).

JUST DO IT :wink:

Maybe on a later date and if the performance is justifiable.

You AMD people have unbelievable amount of problems there is also a solution that support all of those have been ten years it is called Intel Xeon. My system is from seven years ago launched dual xeon e5-2695v2 12c/24t 2.79ghz all core turbo 3.2max hp z820 and it takes four cards and no lane is chared with some problem causing other device actually even more but then have to bother to use risers

You AMD people have unbelievable…

Lol, old school Intel Xeon’s are ok; but I’m planning to do cpu video rendering too. Since the AMD 3900x 12c/24t base is 3.8, boost is 4.6, and is at 105 watts; it easily beats the 2695v2 in performance at a lower wattage.

Also I’m running an e5-2690v2, 40 PCIe lanes is nice, but I want a new motherboard and PCIe 4.0. Also with Bifurcation x4 I can run up to 6 GPUs for 3D rendering with no performance hit for what I’m doing.

Old school Intel Xeon isn’t gonna cut it this time.

An update regarding the Pro WS X570-ACE’s U.2 port. I wanted to try to use it for a regular PCIe AIC with an active riser from Delock, however the motherboard doesn’t POST as soon as the riser is connected to the U.2 port (even if nothing is installed in the riser).

Quite weird since the same U.2 cable and riser work fine if you use them with additional adapters getting the PCIe lanes from the CPU and not the X570 chipset.
