Hi all,
Did anybody had success in running 7 GPUS Nvidia with this switch on Asrock H81 Pro BTC? I have 6 GTX 1080 ti and when I try to add this hub/switch to add 7th card GTX 1070 the system don't recognize it or I can't boot the system (Windows 10).
When I try to connect 5 GPUs to mobo and 6th card to this hub it doesn't work either. It did work once but this 6th card I couldn't change any settings in MSI Afterburner then after restart stop working. I have two of these and none of them works for me.
If you have any ideas or expirience with this Switch I would appreciate any help.

This switch does not work with nVidia cards.

Hi, im trying 1 to 3 adapter but with Nvidia 1060 it is not working, they are not found as devices , with AMD cards its working fine ... Sad

Anyone know if its normal for the Nvidia GPU's not to work with those adapters ?

I have one working fine (still) in an MSI 970A-G43, with Nvidia 1060s. I'm using Windows 7.

(Although, if you have a mix of cards and can connect them such that only the AMD cards go through the adapter, that would likely be a quicker workaround for your troublesthan purchasing a different riser card.)

I'm not sure if any deductive research has been done to support claims about these devices not supporting graphics cards with Nvidia GPUs. It seems this belief is only based on some number of examples.

Yes. These PCI-E spiltters only work with AMD cards.

PCIe 3x or 4x Splitters do not support Nvidia cards, are built primarily for AMD.

That's the first time I've heard of this..are you sure? I can't get mine to work on my Nvidia cards, so this would make sense.

Have you tried inserting your splitter in a way that the motherboard only has as many graphics cards as could be installed without it?

For example, if you have 4 physical PCIe slots on the motherboard, try putting one card directly in the primary x16 slot, then using a splitter card for up to 3 additional cards. This can help check if the splitter card can actually function at all in that board.

That's not true. I have an MSI G43-970A running 6 Nvidia 1060 (3GB) cards using a 1 to 4 splitter.

Hey, I connected a rx 480 to a PCI slot. Not pcie. It smoked! Now my card is not recognized. I've tried in different pc's. Is there a fuse or capacitor that might have blown on the cards board?

Yes if it smoked, it blew a few caps at max. But its not something you can change unfortunately, you'll have to give it in for RMA.

i'm using gigabyte am2+ and am3 old motherboard just about 25-30usd(not new) in here
it have 5 pcie and i'm using 1 to 3 multiplier so all is 7 gpu
and it's all work fine Grin

,all x4 procesor.
i have asrock btc it just can boot with 7 gpu too,cannot boot if i add 8 gpu,no mather what procesor i put on it.
i have asus rampage black edition too(expensive one),it just support i7 procesor,it has 6 pcie,using 1 to 3 multiplier it can boot 8gpu.
biostar 990fxa am3 it have 4 pcie..i can add 2x 1 to 3 Grin

..but it just can boot 7 too,cannot boot if i add 8.
the most i can add gpu is in z170 asus(expensive too),if i'm using celeron it just can boot 7 gpu,if i'm using i7..i can add 2 of 1to3 multiplier and it's working all.
so until now if i build new rig,i just using the gigabyte old one,it's very cheap hahaha Grin

Dude,

Would you please tell me the exact mobo you use?

I'd like to try that.

I am using a88x-g45 and it can only boot to 5. I got to use some stuff to make it boot to 6. However, if I do so, it's less stable.

From everything I read so far, it sounds like it's easier to use a 4 PCIE slot mobo with this PCIE multiplier to run 6 cards, than it is to use a 6 PCIE mobo to run 8 cards...

Yeah, in the end, sometimes cheaper if you use something like an x58 board/system

Correct However I was also able to get a asus am3+ motherboard with 5 slots to work with 7 cards but the last 2 cards were less stable.

What happen if you reduce the frequency?

i had some experience with those switches and some old mobos for a couple of last weeks. neither g31 and g41, nor h61 and some too old chipset mobos didn't see any cards through it, but h81 works well. i don't have any amd mobo, but due to their specs it should work too. well, getting a cheap 2-pcie slot h81 mobo to build a 6 gpu rig looks like a good plan now.

I second that. I want h81 mobo switches

Let's get back to topic of this thread. Can anyone share what 1x3 multiplier they are using that works, I went back through all 4 pages and unless I scrolled to fast, I do not see any suggestions. I tried one from Amazon a couple months ago and it didn't work, I sent it back. Would be nice to have the ability to get these 40-60 dollar boards and use a 1x3 on it for 6 or 7 gpu's. Im not looking for 8+, really don't care about anything higher than 6 tbh.

I have one from amazon on all my mining rigs
Rig setups
4 PCIE slot HP 775 Motherboards (Bought them in bulk for $55 each with CPU and Memory)
Core 2 Duo E8400 CPU's
4GB DDR2 Memory
60GB SSD
Windows 10 Anniversary with all windows Callback/Update features disabled after initial miner setup.
1 1x to 3 1x multiplier from amazon
I have disabled everything in the bios that I can including usb as I use ps/2 KVM's allowing me to make the 4 slot motherboard run 6 cards
If you miss disabling one item in bios then one of the cards will no longer work.

From everything I read so far, it sounds like it's easier to use a 4 PCIE slot mobo with this PCIE multiplier to run 6 cards, than it is to use a 6 PCIE mobo to run 8 cards...
