Title: 6GPU rig cant make it stable, help please Post by: Warlockmng on July 18, 2017, 03:34:49 AM Hello guys,
I'm setting up a RIG (mobo Asus Z270h gaming), 3x Sapphire RX480 Nitro 8GB + 1x Sapphire RX480 Nitro+ 8GB + 2 Sapphire RX470 NITRO+ 4GB. When I connect 1x RX480 Nitro, I'm getting 28.8 with single mining but when I connect 2x RX480 Nitro, one is running at 27.1 and the other one 23.5, same problem when I connect 3x RX480 Nitro (1x 27.2 + 2x 24.5). Weird thing is that when I connect 1 card only (same with all cards) , I get 28.8. Those 3 cards have the same bios mod and samsung memory. Also when I connect all 6 cards, I'm getting 24-25 mhs and only one 27.1. Already tested with afterburner & changed the memory clock with claymore. Could someone could help me with this? Thanks in advance. Title: Re: 6GPU rig cant make it stable, help please Post by: EthereumPY on July 18, 2017, 04:01:04 AM 1) update bios

Thanks for replying, I already did all those modifications. Do you use GEN2 for PCI and PCIe? Thanks again, regards.

Thanks in advance. What OS? Have you tried DDU to remove drivers and re-install? Title: Re: 6GPU rig cant make it stable, help please Post by: Warlockmng on July 18, 2017, 02:43:02 PM What OS?

Will continue testing with windows next weekend. Thanks to all |
