x99 deluxe ii, PCI lanes

[JCBiggs]

Im trying to get my old PC setup for unraid.  I have 2 quadro 2000s, one in slot 1 and one in slot 3.  I also had a m.2 drive in the motherboard, but that was shared with slot 3.  forcing x8 on the card. I would like the cards to both be x16.  

 

I have 4 cards i need to get installed.  2 quadro 2000s, a usb controller card with 2 seperate controllers on board. (x4 card)  and the NVME drive on the asus add in board, (also x4)

 

Thats a total of 40 lanes.  Im trying to determine the best place to put the NVME drive and controller card. (either slot 4 or slot 5)   I "thought"  that some of these lanes were shared with the chipset, or came from the chipset.  I cant find any mention of that  in the users manual and I am  wondering if  maybe I have  my boards confused.

PCIe16_1: Quadro 2000

PCIe16_2: USB card

PCIe16_3: Quadro 2000

PCIe16_5: NVMe drive

 

Cant use any of the U.2 connectors just in case you're wondering

 

In this config the USB card runs on the chipset, but the second Quadro could run at either x16 or x8, I'm not familiar with X99. In theory the PCIe16_4 slot is empty and NVMe SSD only used x4 so there should be enough lanes for dual x16 GPUs, but maybe it will cut PCIe16_2 to x8 just because it detected something in the remaining x16 slots, idk.

 

Not like you're gonna see any difference with the Fermi based Quadro 2000, not even the newest P2000 will se a difference from PCIe 3.0 x4 to x8.

that puts the usb card at gen 2 speeds.  I use usb 3 drives for speed purposes. plus all my devices will have to run off a single port.  I dont see anywhere on the board that anything shares slot pcie16_4.   something does share 5 but Im not using it.   

 

the only "greater than 2" card setup thats actually listed in the manual is a 3 gpu setup with x16 x16 and x8 on slots 1 3 and 5.   

 

Im thinking slots 1 3 4 & 5 and just leave the chipset to its own devices.

pci-e 2.0 x4 is 2 GB/s in both directions.

 

Each usb 3.0 port is 5 gbps or ~ 625 MB/s (590 MiB/s) ... though in real world due to packet overhead and other limitations, you don't get anywhere close to 550 MB/s ... I don't remember the exact number, but I think it's even lower than this.

Anyway, even if you read from all four ports at the same time at maximum speed, you won't saturate the 2 GB/s connection.

No need to worry about it.

 

Anyway... the data you want is in the manual, page 1-8 (26 of 128) and onwards   : https://dlcdnets.asus.com/pub/ASUS/mb/LGA2011/X99-DLX_II/E11357_X99-DELUXE_II_UM_WEB.pdf

 

what you have depends if you have a 28 lane cpu or a 40 lane cpu.

Your right. for some reason I was thinking USB 2 and not pcie 2. derp.
