Does it work?
For connect 2 gpu other in this moderboard
In all
5 gpu connect in this motherboard
This possible???
Sorry for bad english

I got 1 to 3 version and max i can add only 2. Using H81 Pro BTC.

I've got the 1-2 version and that works fine, but there's got to be limits!

Don't waste time with this shitty thing... I tried to work with this 3 times. First time, last time, and never again. This was just pain in the ass and it was not worth the time I invested in putting this together.
Better to "waste" 150$ for new components, because stabilitiy is what it matters :)

Yes, it will work, so I guess you should quite ok)
So go ahead and order it

So the maximum is 8 in total.

Max is 7 in my case. 8 not post.

My moderboard support this riser ?
You are sure??

as far as i know - this one is good enough for AMD cards and not working for NVIDIA GPU

Thanks ..i used amd cards rx 470...so i buy this riser

If you tried to mine the bitcoins with the GPU rig you will never get the profit at all in the mining platform.
When you start mine the top rated altcoins in the sense you will be able to make the profit with the coins since the hash power very less needed to mine the cheaper coins.
I don't understand the what components you are using which is cheaper like 150 USD and all.

That is called a PCIE extender. Although i don't personally own one, i've seen it work on different rigs owned by my friends and acquaintances in our local crypto market. As for stability, that is another thing. Never been around one long enough to see if it will actually cause more of a headache than actually do stable mining. If you can get it cheap, i'd say go for it.

The cost of such modifications is more expensive than buy 2 old motherboard with the ability to connect to them 4 GPU. Second hand motherboard of such level are 10-15 dollars. Why do you complicate your life? I buy a $ 20 kit the power supply, motherboard, processor. For additional power I buy a separate power supply capacity which is enough to connect 8 GPU.

I want buy this riser just 35 usd in iran
If it work in my motherboard ...that buy a motherbord cpu and....better
U friends say it work so i will buy it

Sorry for bad english

I would suggest investing money in a motherboard that can run 6 or 13 cards and not waste your time with this kind of raiser.

Yes you true say...but i have not money for motherboard

Have you check this topic https://bitcointalk.org/index.php?topic=1955358.0 ?

Thanks but in all i not understand what say this topic
I want used this riser but not body in here used that it
I dont know what do i do???

I have use one at H81 Pro BTC, and it not too stable (last gpu not stable). Of course it works, but dont know how long it will last. It kind like gambling.

The short answer is yes it does work, but from what I've seen there some issues, usually the last card is not detected or having problems while mining. But if you are lucky enough, you'll get all your cards detected, and will have a good efficiency out of your system, good luck to you, and please when you get it give a feedback for others 

Only N -1 works always where N being number of extended slots. If you have 3 slots then only 2 works. Don’t ask me why lol

3 slots  in my moderboard h81 mk
With this riser 5 slots worked?? Or no you say 2 slots in all

Mine 1 to 3 >> mean 3 slot extender >> and only works 2 >> so 6 original - 1 + (3-1) = total 7 gpu
I think yours will be 5 or at least 4, do you think it worth for 35 usd?

If 5 gpu in all supported in my moderboard yes it worth for 35 usd

I hope it works. Give us feedback when you try 5 or 6 gpu. Still dont know if 7 is max at H81 Pro BTC or cause the extender only can be use N-1.
