Title: Mining Issue 6x 390's Post by: ericivxx on August 03, 2016, 08:32:43 AM Hello,
I have the following: ASRock H81 PRO BTC Motherboard 6x MSI R9 390 8GB GPU's 8GB DDR3 RAM 2x EVGA Supernova 1300 watt PSU Wondering if anyone has had issues with not being able to mine on all 6 cards... I can mine 5 with no problem, but it won't recognize the 6th card. It's showing GPU 1,3,4,5,6 but not 2... However GPU 2 should be the 16x PCIE Slot, which is what my monitor is plugged into which works, so not sure why it's not recognizing it as a mining GPU. Anyone had this issue? I have changed PCIE to Gen 1 in the BIOS already also. Title: Re: Mining Issue 6x 390's Post by: sp_ on August 03, 2016, 10:23:56 AM 300 * 6 = 1800watt. (won't work on a 1300W psu) You have 2 psu's. But you can mod the card to use 180watt each with a bios mod. Then you can run 6x 390 on a single 1300w psu If you get code 43 errors there is a registry patch on the net you can run. (Run the exe as administrator, check the mod registry checkbox and click mod ) https://bitcointalk.org/index.php?topic=712228.0 Title: Re: Mining Issue 6x 390's Post by: ericivxx on August 04, 2016, 01:26:23 AM 300 * 6 = 1800watt.

Also, I'm hashing on 5 of the cards... I have 3GPU's on 1 PSU and 3 on the other, so it should be fine right?

No, it's connected to the other PSU which is only powering 3 cards, nothing else... And it's weird because PCIE 1,3,4,5,6, are showing... What is labeled as PCIE2 is the 16x slot, but my monitor is plugged into that card but it's not showing as an active mining card...

Bumping in case anyone has anything else lol Title: Re: Mining Issue 6x 390's Post by: Mzie on August 13, 2016, 06:57:10 PM Try to exchange and connect GPU 2 on the motherboard then put the other gpu on the other psu

Connect GPU 2 to a different PCI-E?

Connect GPU 2 to a different PCI-E? For that motherboard, it can recognise 5 GPUs. But it will have code 43 error if you have 6 GPU. You need 6 GPU mod. Title: Re: Mining Issue 6x 390's Post by: robertkedves on August 24, 2016, 08:35:11 AM Try to user risers as well for that card. If it still doesn't work, switch the risers between them or try new risers.
I'm using windows, 6 gpu's on the same board (ASROCK H81 PRO BTC) and it's working perfectly. Good luck Title: Re: Mining Issue 6x 390's Post by: ericivxx on August 30, 2016, 07:29:55 PM Try to user risers as well for that card.

Good luck Got it, it was the riser!! What also threw me off, was that ETHOS was saying that card 1,3,4,5,6 were working, so I assumed that corresponded to the PCI slot... But it didn't! It was actually the PCIE-1 slot card that wasn't working... Now have all 6 mining perfectly! Thank you guys for the help! |
