Title: Unable to detect more than 3 GPU on msi z77 gd65 with Windows8 Post by: cerberre on March 29, 2014, 11:07:50 AM Do I need to use pin shorting for this mobo ?
I tried to use dummy plugs it does not work. Although I have the same setup with Linux and I have 4 cards running. Title: Re: Unable to detect more than 3 GPU on msi z77 gd65 with Windows8 Post by: cerberre on March 29, 2014, 06:11:09 PM anyone ?
Title: Re: Unable to detect more than 3 GPU on msi z77 gd65 with Windows8 Post by: zombie007 on March 29, 2014, 06:17:32 PM anyone ? runnning 5 cards with no problem on win8.1, even 7 is possible with linux. Risers ? Type of cards ? PSU? CPU ? Title: Re: Unable to detect more than 3 GPU on msi z77 gd65 with Windows8 Post by: Trongersoll on March 29, 2014, 06:58:08 PM you are mining Bitcoins with GPUs?
Title: Re: Unable to detect more than 3 GPU on msi z77 gd65 with Windows8 Post by: nybbler905 on March 29, 2014, 11:10:45 PM you are mining Bitcoins with GPUs? Doubtfull, it's more profitable to mine any script coin and convert to BTC compared to the low entry cost of ASIC mining. Still... How many ' dummy ' plugs you using per card?? Windows 95 and newer all have a hard coded 9 screen max so If you are doing more than 1 screen ( plug or real screen attached ) per card, you are going to have issues. Technically ( not realisticaly ) you could have 9 GPU cards set up and running in Winblows OR what ever you can stuff in for LINUX. More details on how you are connecting would assist us in assisting you.

I tried to put a dummy plug into the 4th card but it is not detected. My 4 Cards are connected to pci 1x slots on the mobo.

https://bitcointalk.org/index.php?topic=36061 I'd bet it's covered there either in BIOS settings and/or jumpering the slot Title: Re: Unable to detect more than 3 GPU on msi z77 gd65 with Windows8 Post by: -ck on March 30, 2014, 10:06:35 PM this should be a sticky in troubleshooting hardware/Multi-GPU mining No point stickying information on hardware that is only of historical value to bitcoin mining.https://bitcointalk.org/index.php?topic=36061 I'd bet it's covered there either in BIOS settings and/or jumpering the slot Title: Re: Unable to detect more than 3 GPU on msi z77 gd65 with Windows8 Post by: cerberre on March 31, 2014, 08:14:12 AM FYI I am mining alt coins and selling them for bitcoins.
In the BIOS, for internal graphics adapter I can choose between PEG and ICG. I had PEG before and I switched to ICG. I also enabled Multi Monitor.

I cannot see this mobo in the list.

I cannot see this mobo in the list. That isn't an all inclusive list. Try the A1 B17 jumper and see if it detects. It's a quick troubleshooting step to find out if that is your issue.

I intend to try first to disconnect one working card to make sure that it is actually the pci1x slot that is not recognized Title: Re: Unable to detect more than 3 GPU on msi z77 gd65 with Windows8 Post by: pf22100 on April 01, 2014, 05:23:24 PM set your pci slots to GEN1 in the bios (default is gen3)
Title: Re: Unable to detect more than 3 GPU on msi z77 gd65 with Windows8 Post by: cerberre on April 05, 2014, 01:31:27 AM I looked in the bios but find nothing where I can select gen. I will double check
Title: Re: Unable to detect more than 3 GPU on msi z77 gd65 with Windows8 Post by: kcheel on April 05, 2014, 03:56:21 AM Yeah, there is not a setting like that in the BIOS IIRC. I have a rig with this board. I could get 5 GPU's in it easily, just never could get the 6th to even show up at all in Windows. I used the 4 1x slots and the first 16x slot only. The 2nd and 3rd 16x slots either did nothing or caused other cards not to show up. If you have not tried already, just start at the top and plug one card in at a time, boot and check Device Manager to verify its detected, rinse and repeat. Just skip the 2nd and 3rd 16x slot.
Title: Re: Unable to detect more than 3 GPU on msi z77 gd65 with Windows8 Post by: cerberre on April 10, 2014, 09:50:46 AM ok will try this.
Did you have to pin short some pci slot or no ? |
