Hi, I have bought following components recently (all new, not 2nd hand)
I have installed HiveOS version 5.10.0 I have upgraded BIOS to version 1.30 with instant flash The system recognizes the first two GPU slots and they are mining ok. Slots 3,4,5 & 6 are not recognized at all. For slots 5 & 6 red lights are burning. For slots 3 & 4 there are no red lights but GPU fans are not running either. On another rig all GPUs are working ok. Are the molex connectors obligatory for GPUs 3,4,5 & 6? Like, do I need secondary PSU to be able to give power with molex & PCIe to GPUs 3-6? Or is this still some configuration issue? |

Hi Luppakorva, Thank you for your post. Connecting the Molex connector to H510 Pro BTC+ is necessary for the PCIE3~6 slot. It provides the power for these slots. The below link shows our recommendation to set up the mining rig with H510 Pro BTC+. https://www.asrock.com/support/faq.asp?id=503" rel="nofollow - https://www.asrock.com/support/faq.asp?id=503 All the best ASRock TSD |

Thx, added 2nd PSU and it's working now 1st slot: PCIe Power from PSU 1 2nd slot: PCIe Power from PSU 1 3rd slot: PCIe Power from PSU 1, molex power from PSU 1 4th slot: PCIe Power from PSU 2, molex power from PSU 2 5th slot: PCIe Power from PSU 2, molex power from PSU 2 6th slot: PCIe Power from PSU 2, molex power from PSU 2 |

Anyone knows if it's possible to got it running using only one psu? I got my h510 pro BTC+ and I am planning to connect 1660ti (6 of them). Not power hungry GPUs. Would be possible to power them only with one psu? And if yes, should I be careful of something when I get my psu? |

I'm also interested in this. I'm running smoothly 5 GPU, but the 6th is not recognized on the POST. It receive power because fans are spinning, but is not recognized on the POST and in the OS. |

I did not actually need a 2nd PSU either, since 6 x 2060's take only around 480W (mining ETH around 192 Mh/s). But according to this previous comment "Connecting the Molex connector to H510 Pro BTC+ is necessary for the PCIE3~6 slot. It provides the power for these slots." the 2nd PSU is necessary. Actually with 2 PSUs the recommended configuration is to power 1~3 with 1st PSU and 4~6 with 2nd PSU (with 3 PSUs the config is PSU 1: 1~2, PSU 2: 3~4, PSU 3: 5~6). At least one important issue is not to mix PCIe and molex connections with different PSUs, like do NOT connect all four molex connections from PSU 2 and then PCIe for slots 1~3 from PSU 1 and PCIe for slots 4~6 from PSU 2 (this way you might end up burning your MOBO and/or GPU). Correct way is to first connect PCIe for slots 1~3 and molex for slot 3 from PSU 1. Second, connect PCIe for slots 4~6 and molex for slots 4~6 from PSU 2. If some of the GPUs is not recognized (and they are all identical), double check your connections; remove PCIe from GPU and PSU and reconnect. Also remove molex from GPU and MOBO and reconnect. And finally remove GPU from MOBO and reinstall. This way I got them all to work. I need to downgrade my PSUs at some point but the main thing for now was they all were recognized and functioning. |

Are you running HiveOS? Perhaps update your GPU driver? Other option is to flash MOBO BIOS. |

This problem happens both on HiveOs that on Nicehash with Windows. The GPU on the 4th slot is not recognized. I have to check if it is broken actually. My MB has the latest 1.4 BIOS version. |
