Hi, I did the 1x to 16x shorting trick and it detected the graphics card. I am using windows 7 x64 first graphics card is 6870 second is 5770. the 6870 is in the 16x slot then 5770 is on the 1x to 16x. Graphics show on the 5770 but not the 6870 and when i load the miner it just shoes 0-0 and 0-1 being the processor.

which driver version are you using? if its 11.6 then are you using a dummy plug?

sorry now this is where I am a bit confused because I am new at this, that and I am a bit intoxicated. But what do you mean by version number?

Hello sirs I heard a PCIE1 is all you need for mining but I can not get mine working on my FoxConn $50 Mobo, is it because its a bad model or is it more an issue with drivers? I'm using 10.6 ubuntu and Sata > 6 pin adapters for power with a PCIE1X/molex riser to attempt to run the card.  No avail though.

http://blog.zorinaq.com/?e=42 This has been down also and everyone keeps saying the guide was there.  Any thoughts?

well, at first my gpu did not show up as well. Whats on blog.zorinaq is the guide to the 2 pins so your os detects the gpu

there is the picture of which pins to connect to each other.

this is where im stuck at the moment, my gpu is detected but I can online mine off me 5770 on the 1x-16x and not the 6870.

Yes, I am on version 11.6. Do I really need a dummy plug even after the pin shorting trick? Both graphics cards shows up on the device manager. However when I open the miner I only have two options which 0-0 and 0-1 instead of having 0-0, 0-1, and 0-2 like my other desktop which has 2 graphics cards on 16x slots.

0-0 went from 0-0 Barts to 0-0 Juniper


Thanks for the help to find the version!

Oh man so by sticking a wire in those two pins and plugging my card into the PCI1 riser I'm golden? Should I update 10.6 ubuntu?

doing the pin trick should enable your os to see the card. However this is where I am stuck I see the card but cant mine on both cards... I found somewhere that told me to try to reinstall catalyst. I hope this fixes my problem! I know its frustrating having a card laying around when it can be making btc!!! LOL

bump please guys I need to have this figured out!

if its showing up in the device manager but not in guiminer then you need the dummy plug...or you could download catalyst version 11.7..

Just curious if the problem was solved by catalyst update...  Or if the problem was solved at all, and how exactly.

Nope, not for me, maybe that a1-b17 Pin will work

Ok, I read this thread a couple times
Im confused..


Short the PINS, AND USE a Dummy plug..

Have you done both ?

Would you believe I have the same board..  same issue

at least I suspect its the same board

cheapo, foxconn, one 16x, which works fine..

and a 1x above it.

Cant get anything to mine in it, yet it shows in device manager (win xp)

tried various cards..  its deff the slot..

Will continue testing

Does it look like this one? http://www.asrock.com/mb/overview.asp?Model=M3N78D I know it isn't a foxconn but i know a foxconn witht has an similar layout. I only got the x16 and upper x1 pcie working. Thats with two cards only. On the other x1 slots the cards fan goes mad spinning hard, going down and spinning hard again. Got the wire trick and dummy plug so my bet is it is a hardware problem. do you have any other devices that plug in x1 slots? curious if they will work
