MSI X570 Ace with 3 Gpus???

Hi everybody, I previously owned a desktop (majorly for 3D rendering and Deep Learning) with the following specs:

Processor: AMD 5950X

Ram: G.SKILL TridentZ RGB Series 128GB (4 x 32GB) 288-Pin DDR4 SDRAM DDR4 4000

Motherboard: MSI X570 ACE

GPU: 2 x 2080Ti founder edition (did no do SLI since does not need it)

Storage: 1 x SAMSUNG 980 PRO M.2 2280 2TB, 2 x Samsung 860 EVO SSD 4TB

Power: 1300W Seasonic Gold

Case: LIAN LI O11 Dynamic XL ROG

 

Now I got one more 3080 Ti, I was wondering whether it is possible for me to add it to the current setup?

 

Since the specs of the Mobo said:

  1. 1x PCIe 4.0/ 3.0 x16 slot (PCI_E5, supports x4 mode)
  2. 2x PCIe 4.0/ 3.0 x1 slot
  3. 2x PCIe 4.0/ 3.0 x16 slots (PCI_E1, PCI_E3)
  • 3rd Gen AMD Ryzen™ support PCIe 4.0 x16/x0, x8/x8 modes
  • 2nd Gen AMD Ryzen™ support PCIe 3.0 x16/x0, x8/x8 modes
  • Ryzen™ 4000 G-Series support PCIe 3.0 x16/x0, x8/x8 modes
  • Ryzen™ with Radeon™ Vega Graphics and 2nd Gen AMD Ryzen™ with Radeon™ Graphics support PCIe 3.0 x8 mode1

If I understand it correctly, I could put 3080Ti on the top PCIe (which should be x16 in use since does not enable SLI, but x8 when using CUDA?), and 2080Tis on one x8 and x4.

Will this work? (If not work, I could sell one 2080Ti..

It should be possible but it will most likely go in x8 x4 x4 mode for the gpu's. Cuda works any time. Since you have it why not just try?

Should be fine, if it doesn't work just sell the extra like you said.

The top 2 will run at x8 from CPU, the 3rd will run at x4 from chipset.

I need one more gpu cable and it is shipping so I cannot try it now...

Thanks for the reply!

Thanks for your reply! Also, I am curious whether 1300w would be sufficient?

Should be fine

My PCs: Desky | Beddie | Miney | Benchie

Things I need help with: (nothing at the moment)

Spoiler

none atm

I hate Intel's pricing, Ryzen's weird quirks, Nvidia's pricing, and Radeon GPUs in general

Spoiler

Products I like:

Spoiler

Sony Xperia Z1 / Z2 / 10 ii, Asus Strix 970 / 1070, Samsung SSD, WD HDD, Corsair PSUs (AX, RM, CX(grey)), GeForce GPU, NZXT N450/S340, be quiet! Coolers, G.Skill Trident RAM, Logitech M525, Logitech G440, Razer Deathadder Elite

Products I hate:

Spoiler

Xperia Z3, XiaoMi 5c, Radeon GPUs, Razer Audio Products, any bloatwares

Companies I absolutely adore: (and hope it stays that way)

Spoiler

be quiet! - sent me AM4 mounting for my DRP3 even though it's way past the timeframe stated, no questions asked

Corsair - very good RMA experience, absolutely recommend

Companies I hate:

Spoiler

Nvidia, Intel, Apple, TMT (Thundermatch, a retailer)

Personal Blacklisted Companies:

Spoiler

Acer: shit tier quality products, shit tier customer service thus far, they "tried" to solve my issue but they arent really doing anything but delaying and delaying. (on-going case since July)

Gigabyte: horrible customer service (gigabyte had literally 0 customer service, asked me to go to retailer with NO WAY to email them about a question) but at least they fixed my shit in ONE MONTH (would probably take me 1 hour to fix if they let me email them)

XiaoMi Phones: built like a tank but the software is buggy as all hell

Seagate HDD: had too many dead seagate drives

Kingston SSD: 300V controller swap thingy

Razer (except their mouse)

Remember, just because I had good/bad experiences with these companies/product, doesn't mean you will have similar experiences too. I would still recommend these products if they made sense for your needs, but I'll add a disclaimer of my experience if it's relevant. Feel free to DM me asking why they are where they are.

What psu? If it's a good one yeah the 2080ti's are very efficient cards for what they offer.

Since when do you have it? Pre 2018 units kinda do not like the rtx3000 series and will trigger their overcurrent protection falsely.
