Is my 3080 a donkey??

[fokum8]

I recently bought a Zotac 3080 10GB from eBay and while watching some Starfield benchmarks online I noticed they get much better performance with a 3080 on 1440p. Tried tinkering with various settings but it's always 10-20FPS (roughly) lower than what others with the same setup are showing. This got me wondering why I am consistently getting lower performance. It shows 90-100% GPU usage when I play the game now.

 

 

Specs:

 

i7 10700

16GB DDR4 3200mhz

Zotac RTX 3080 10GB

650W Corsair PSU

Enable Resizable BAR and figure out why your GPU is only running at x4 1.1 instead of x16 4.0

I am using the 2nd slot on my MB because the first one is faulty. Could that be a problem?

What motherboard? It could be its only electrically wired for x4 only. Most 2nd slots are either electrically x8 or x4 only, not x16 as the first slot is.

It's a Gigabyte B560 HD3 and this is what it says on their site:

 

• 1 x PCI Express x16 slot, running at x16 (PCIEX16)
  * For optimum performance, if only one PCI Express graphics card is to be installed, be sure to install it in the PCIEX16 slot.
  (The PCIEX16 slot conforms to PCI Express 4.0 standard.)^{(The broken one)}
• 1 x PCI Express x16 slot, running at x4 (PCIEX4)
• 2 x PCI Express x1 slots
  (The PCIEX4 and PCIEX1 slots conform to PCI Express 3.0 standard.)

 

So does this actually effect my performance? Is it worth buying a new motherboard? It hints at it there.

Sounds like you need a new platform. Unless you can get it to run in at least 8x 3.0, you're going to have a bad time.

2nd x16 slot is only physically wired for x4 and seems to only be running at 3.0 speeds. Definitively need to replace this board to get the most out of your system. This would be your problem. Also, its likely running through your chipset and NOT the CPU like it would be in the top slot.

I mean your current setup is going to reduce performance. That being said I wouldn't bother upgrading the motherboard unless I was upgrading the cpu at least.

PCI-E 3.0 @ X4 will impact performance.

Also, probably slight CPU bottleneck as well with a i7-10700.

What a coincidence I was literally watching this: 

When I saw your reply lol

keep in mind, this was testing Gen3 and Gen4, both at X16.

Gen3 X4 is equivalent to Gen2 X8...or Gen1 X16.

Man this thread made me feel like I had a huge BBQ sauce stain on the back of my pants and nobody told me for weeks

As long as you learned something along the way, thats all that matters. No one person knows everything. This is where the saying of it takes a village to raise a kid comes from.

Yeah thank you for your help otherwise I would've never realized. I assumed that PCIe slots would be functionally the same but I guess that's why SLI isn't really a thing anymore right? I have just ordered a new motherboard

SLI and Crossfire isn't a thing anymore because game developers and GPU developers pretty much by tacit consent all abandoned it. Even in its heyday it wasn't great and to really make a game scale well with multiple GPUs it required work that only a very small fraction of players would benefit from. DX12 and Vulkan theoretically let multiple, non-identical GPUs work together so you could mix and match different models of card or even AMD and Nvidia cards in the same system but it shifts ALL the burden to the game developers to implement instead of AMD or Nvidia releasing "profiles" and developers all went "lol no fuck that."

 

BUT even when SLI/Crossfire was moderately mainstream, the boards that supported it were typically running the two cards at x8/x8 as I recall, and that was preferable to the boards that would run the first card at x16 but drop the second card to x4.

That makes sense and it's probably not power efficient either, given that higher end GPU's consume the majority of a PCs total power
