ASUS Maximus IV Extreme-Z Question ???

post #1 of 9
Thread Starter 

I have 1 EVGA gtx 480
1 asus xonar dx pcie x1 soundcard
1 Prof dvb s2 8000 pcie x1 satellite receiver card

when I put the asus xonar on slot 6 and prof card on slot 5, my gtx 480 (on slot 1) will run @ x16 or X8

Im pretty sure that card should have no effect on your pcie bandwith while gaming so your single card should stay at X16 but if for somereason on that board it does you will not notice any performance diffrence between x16 and x8

With this board I found that it's better to attempt to bypass the NF200 and use the x8/x8 off the CPU for GPUs. So in essence you will see better performance coming from x8 off the CPU then x16 off the NF200.

To do what you want without waking up the NF200 and causing unnecessary heat I would throw the two x1 cards in slot 4 and slot 6.

On this particular board the use of certain PCI-e x16 slots will enable the NF200 IIRC so it's best to use slots 1, 4, and 6 for this setup.

A GPU running x16 off the NF200 will actually be slower than x8 off the CPU on SB as there is nothing in between the CPU and GPU to slow down the data path. With the NF200 it would add a unnecessary latency as the NF200 is the middleman between cards and GPU/ expansion cards.

I don't think it will run x16 in any configuration with 3 cards total.

You would be better off running the 480 at x8 off the CPU.

I have my 580s in slot 1 and slot 4 with my Xonar in slot 6 and the GPUs are running x8 off the CPU and the x1 off the Z68 chipset.

You need to keep the GPU in slot 1. its native 16x with no NF200. run the other two in Slots 5 and 6 and you should be fine.

NF200 shouldnt be active unless 1, 3 and 5 are in use, because any other configuration and they will run at 8x, period. And slot 1 will only run at 8x if you have a card in slot 4 (SLI).

You can verify this using the iGPU in the BIOS, it tells you exactly what each card is running at.

1, 4 and 6 would make his gpu run at 8x. slot 1 is native 16x and will be faster then the 8x it would run on if you use slot 4. You run SLI so it's obviously faster, but it won't be for him.

Sorry. I figured that using 5 & 6 would activate NF200.
