Yes, as the MOBO has a PCIe x16 slot, I had just one card running on the rig and at each time the same result.

I lowered the core and memeory, as suggested, 1100/1900 with same result.  I even did 670/1700 and same, stopped mining.

Help please

  

The GPU's have not been bios modded, stock.

Temps never reached more then 75

I took the rig apart, new PCIE risers and cables, same result. Placed each RX 580 into the one PCIe x16 slots on board and same result. It's not the hardware connecting the GPU to the MOBO.  

Can clarify in more detail the, "software issue is a bad timing strap pasted into the BIOS that is causing the errors".

Thank you both!

Hello and HELP please,

I was mining Monero with 2 RX 580 (612 H/s) for several days, no issues. Afterburner core-1340 memory-2000 power - -16 temp-74.  The issue is that mining program QUITS after 1 minute 20 seconds.  For past 48 hours, XMRig/2.52 runs just long enough to find 2 jobs. Running Claymore quit and closes after 1 min 17 seconds.  Both GPU's stop with or without running Awesome Miner.

I have uninstalled the PCI risers, cards, and drivers.  Reinstalled, and the same issue occurs.

What else can I do??
Thank you in advance,


1070ti runs fine no issues.

2x MSI single fan Radeon RX 580 8GB (Micron) stock settings, running on B250 mob, Win 10 pro, PCI-E risers, 8 GB RAM, I7-7700K, also running  MSI 1070ti Armor on EVGA 1000 watt PSU, SSD sandisk 120 GB HD. Killowatt per hour 450-510.

Thank you for the advice.
I want to get into ASIC mining.  The Baikal Giant B seems to good to be true. Still would love to get one, or two and sell them in June.
I guess I should get in the preorders for the 2nd batch of Obelisk which will ship on or before August 31, 2018. Which miner, the one for Decred with the DCR1 miner or Siacoin with the SC1?
