pci-e lanes - sli - & intel 400gb pci-e ssd question

post #1 of 12
Thread Starter 
i run two 980's on my z87 hero motherboard - knowing the following things
-the 980's run x8 and x8 pci-e speed.
-sli requires that as a minimum (x8 and x8)
-the 4790k is limited to a maximum of 16 lanes

what happens if i try to plug in an intel pci-e ssd? i dont have lanes available on the cpu for it but i've got slots available.

it also depends partially on what the price of the 400gb shell shocker deal ends up being in a few hours lol

The cpu itself has 16 pcie 3.0 lanes however I believe the chipset has an additional 8 pcie 2.0 lanes so if you use the pcie 2.0 slot for your ssd it shouldn't pull from your 3.0 lanes. However the 1x slots would also pull from the chipset so I wouldn't use the 1x slots along with the pcie 2.0 16x slot.

ahh ok i found in the motherboard specifications that it supports pci-e 2.0 that shares with the other 2.0 lanes as you stated. excellent, so it will work. it says it supports up to x4 mode though which is theoretically 2000MB/s ... fast but has anyone benchmarked it on x4 pci-e 2.0 lanes like that? i'd rather not get 75% of the speed out of it. might not be worth it then.

Hey man.

So yea on most Z87 if the last slot is PCI-E 2.0, then that means it comes from the PCH and as a maximum it's 4x (the PCH has 8x on Z87, but devices use those lanes ex. a NIC uses one PCI-E lane, a USB 3.0 or SATA controller might use one, you might have 1x PCI-E slots too). So 2x PCI-E 2.0 bottlenecks around 800 MB/s or a little more... so 4X might not reach your estimates.

You really don't have many options than just to run in that slot, and I doubt you will notice a big difference unless you are doing really big mile moves.

The only options you have are to upgrade to a X series platform or Z170 or upgrade your motherboard. There are some boards for Z87 that have a PLX bridge that takes the 16 lanes and provides 32 for devices, that might provide you better scores, not sure how the PLX will affect it with two GPUs on the line. If you go with that, then one of your GPUs will probably run 16x, the other at 8x, and your PCi-E SSD at 4x (I also don't know if the system will boot to the drive, but I would think it could).

Not trying to steal the thread; but, I came here with almost the exact same question for z170 chipset.

Question:
1. Would a single Graphics card x16 become reduced to X8 using 1 or 2 of these Ultra M.2 Slots(x4)?
2. If running in x8 PCIe would the GPU take a performance hit? Currently, I'm using a 780 on a PCIe 2.0 x 16 slot which is the same thing.



I'm looking real hard at the Asrock Extreme 7+ which offers 3 X Ultra M.2(PCIe x4) slots.


Triple Ultra M.2 32 Gb/s (PCIe Gen3 x4 & SATA3)

The PCIe Gen3 x4 Ultra M.2 interface pushes data transfer speeds up to 32Gb/s. In addition, it also supports SATA3 6Gb/s M.2 modules, and is compatible with ASRock's U.2 Kit for installing some of the world's fastest U.2 PCIe Gen3 x4 SSDs.

The Secret of Ultra M.2

Ultra M.2 is one of ASRock creative innovations. Compared to normal M.2 with PCIe Gen2 x2 bandwidth, ASRock is the first one in the world to double the M.2 bandwidth to PCIe Gen3 x4! Furthermore, the layout of Ultra M.2 is also specially designed. On a regular motherboard design, the signal route starts from the M.2 device, goes through the onboard chipset, and finally reaches CPU. In contrast, by connecting the M.2 interface to CPU directly, ASRock Ultra M.2 has lower latency and pushes the I/O speed to a new level.

From this article, it would appear that even if the GPU(NVidia) is running at X8 it doesn't matter.

i understand that about gaming 8x is fine for the video cards my question was... is 4x pci-e 2.0 ok for the intel pci-e 400gb drive do you think?

I'm completely shooting from the hip here; because, it sounds like you are about to pull the trigger on this SSD. But WAIT That intel SSD requires a NVME bios, from everything I have read on them. To my understanding the required NVME bios is only available on X99 and Z170 chipsets. Even if it does work on your MoBo the speed is going to be cut in half using PCIe 2.0.

Yea there is a guy who has some guide on adding NVMe support to your BIOS, not sure how well it would work.
