PCI-Express - will I slow down my 480 with a soundcard?

post #1 of 17
Thread Starter 
Second question for the OCN experts in 2 days biggrin.gif

Recently (2 days ago) updated my rig to a Gigabyte GA-Z77X-UD5H & i7 2700K, (beware anyone buying this board that the shipped F4 bios is VERY buggy) and am not happy with the on-board audio as I would like something that can offer native AC3 output for all sound, not just DVD.

Anyhow, with that in mind, if I purchase an ASUS Xonar PCI-E soundcard and install it in a 4x slot, will that step my 480 GTX down to 8x as its using bandwidth on the PCI-E bus? If it does step my 480 down to 8x - will I notice any difference? Currently CPU-Z reports that the 480 is at 16x.

Thanks smile.gif

a 480 will not use all the bandwidth of an x8 slot if infact it does step it down.

Edit: I'd put the sound card in the top x1 slot above the video card.

No, If your board is x16/x4, there will be no speed change. Even x8 has adequate bandwidth for a 480.

Well you only have 16 PCI-E lanes on Z77 so yes it will need to use 4 of the lanes you're currently using for your 480 so I guess your 480 will 'downgrade' to x8. Whether that would have any noticeable effect on your gaming though is a different matter.

Interesting estebanrey : That was my initial thought, though having looked at the block diagram it seems the full size slots are the only ones that directly interface the CPU, the x4 slots are all direct Z77, so I'm now wondering if I will see a downspeed?

I was under the impression that there are only so many PCI-E lanes available to a chipset regradless of how they interact with the CPU but I'm not an expert by any means. Anyway, according to Wiki....

http://en.wikipedia.org/wiki/LGA_1155

...under Ivybridge Z77, the option you would be using would be the last one listed.."or 1 × PCIe 3.0 ×8 + 2 × PCIe 3.0 ×4" I would suspect. So your 480 will be running at x8, your Asus Sonar would be running at x4 and you'd have 4 PCI-E lanes unused/spare. Funny really because you'd be using less PCI-Lanes in total (12) than you are now despite having more kit using them.

Now an x16 slot on PCI-E 2.0 runs at 8GB/s (Your card is PCI-E 2.0 even though the slot if capable of 3.0 speeds) so the question is, does your card need more than the 4GB/s you'll get with x8 to run. Again I would suspect not.

Very interesting indeed - thanks for the wiki link too - the card is on order now (Asus Xonar D2X) so I'll update the thread once its installed, should be with me tomorrow. Thanks smile.gif

between 16x and 8x there is less than a 2% performance loss (with gtx 580's i believe) It really is no noticable difference (around 1-3fps)
You wont notice any difference unless something goes majorly wrong.
