X99 PCIe lane switching

[drwhimsy13]

thank you , is there ANY  MSI motherboard which I can plug my 5930 and 2 970s into and achieve enough slot separation to run overclock cool on vga cards and get 16 lanes on both cards ? appreciate your thoughts

X99A RAIDER would be a Good choice for that as it is capable of a 3 slot spaced gap between the 2 x16 slots so it would have full x16 on both cards! (that board only has 3 slots and is meant for 2 way SLI at full speed)

Also all X99 boards above your Gaming 7. That means all Gaming 9 and XPower versions.

Hi

Sorry for being dense but I'm not sure I understand. I just bought a Samsung 950 Pro that im using together with my 2 AMD cards and a 5820K. And from my understanding I should be able to run the 950 Pro at 4x speed in the M.2 slot. Is that correct? Because I cant seem to get it above 2x right now.

Depends what slots they are in.
Did you set M.2 PCH Strap to M.2 PCIE.

Hi,

I have the Godlike gaming and have the R9 295X2 in Slot 1. I am planning to add the Samsung 950Pro in the M2 slot. Please advise the switching and if possible the diagram

Thanks in advance

Hi

Keep it as it is. And simply insert the M.2 drive to the slot, should work just fine.

thanks a ton

Correct me if i am wrong but i shouldn't have any trouble using the 5th slot (only) in my x99a Godlike Mobo for my MSI 980 ti 6gb?
(trying to trouble shoot any and all possible issues as my 6.3 audio jack is not being detected)

Thanks

Hi

It should work fine. Though still depends what CPU you have and what devices are in other slots.

It depends what you consider as trouble.

Ive made my own thread asking this question .  so will ask the same question here . i have also sent a message to customer service as cant believe this is not a big problem .

Im very upset to learn that my 2 x 980ti in slot 1 and slot 3 are only running at 8x/8x using the msi gaming long bridge . i automatically assumes that because the bridge only reaches 3 slots then i thought this was it and put the cards in slot 1 and slot 3 . now i learn that  i can only have the sli'ed cards ion 1 and 4 slot . how is this even possible if you have a watercooled set up and to use the advertised 4 slot gaming bridge long ? 

i wont notice the speed in games but i built a very expensive water cooled (hardline tubing set up ) and my system cant bench to its full potential . dont get me wrong the board is one of the best for overclocking as i have a stable 4.75ghz on 1.27v with my 5960x J batch chip and runs very cool indeed on fill load . but the layout for the PCIE is a nightmare and i feel misled for a very expensive motherboard

I have mine at E1 and E3. That makes them x16 and x16..... They are almost touching. Would it be back to move the bottom one down to E5 which is x8....How much of a difference to there?

If you have the X99 SLI Plus board or the Krait and you move the card to slot 5 it will make both cards run at x8. Slot 5 is only wired for an x8 and the "switch" gets tripped and makes your master gpu run at x8 as well. I just went through this and had to get rid of my EK Triple Serial Connector (that kept the cards in slots 1 and 5) for a Dual Serial Connector having the cards in slots 1 and 3. Its the only way to get x16 on both cards on this board.

Hi all,

Hopefully someone can help me out with this.
I have the Godlike motherboard with a 5820k CPU and I am trying to work out the lane configuration for 2-way SLI with a sound card and an M.2. I was thinking E1 and E2 for the GPU's and then E4 for the sound card, but would it be possible to use E1 and E4 for the GPU's and then E5 for the sound card and just have it run at a lower Gen setting so as to not impact the other lane speeds, or would it simply allow it as it stood?

Thanks.

that board splits lanes the same as a X99S gaming 9 AC

you would have to use 1,2 and 4 as using slot 5 with that CPU will make your M.2 use the PCH lanes on the chipset as the card in the lower slot would use the block of 4 PCI-E lanes that the M.2 is using making it much slower!

Thank you for clearing that up for me!

no problem as it can be confusing what it will do if you don't know!

It is pretty amazing u guys can do something like this, u guys r almost tech savvy than some average Joe end user like me, salute to u, and I learn a lot from all these great posts

Hi
Just wanted to check if I generally understood this correctly.
I have X99A SLI plus motherboard, 5820k cpu and 2x970GTX in SLI. I have nothing else connected.

I tried putting those two cards E1 and E3. Everything worked of course, but as I run couple of benchmarks top card started to heat up much much faster, reaching 85 degrees very fast.

I then decided to put second card in E5 (so E1 an E5). Nvidia inspector shows that both cards are now running at 3.0 x 8.
However temperatures are now equally low, and there is 0 percent loss in performance in any benchmark software.

So I was wondering, since these two cards supposed to work in sync, is there ANY benefit in having one at x16 and other in x8 while they are in SLI?

No, x16/x8 or x8/x8 is totally irrelevant. Stick with the better temps and x8/x8
