Brenton Spear Posted July 2, 2022 Share Posted July 2, 2022 (edited) Hi, I have been running UNRAID on a Dell R510 for about 3 years and I upgrade to an R720 about 4 weeks ago. It has been running well. My Setup: Dell R720 with the following specs: UNRAID 6.10.3 Pro edition license Xeon E5-2670 115W CPUs 384GB RAM Onboard H710P HBA controller flashed to IT mode - Runs the 8 drives int he R720 Dual 1100W PSU iDRAC Broadcom integrated 4 port 2x 1GB + 2x 10GB NIC Riser 1: (3x X8 CPU2) Riser 2: (1x X16 CPU2 & 1x X8 CPU1) Riser 3: (2x X8 CPU2) - Note it is not the GPU Kit version I have the following cards in the server: Riser 1: LSI 9200-8e plugged into slot 1 (X8 CPU2) Riser 2: empty Riser 3: empty I have an MD1200 plugged into the LSI 9200-8e card above. This is working as expected. The LSI card posts on boot and the drives in the MD1200 can be seen by UNRAID under Unassigned Devices. The Problem: When I plug a GTX 1080 Founders Edition GPU into Riser 2 - Slot 4 (X16 CPU2), using the Dell GPU power cable plugged into the riser and the card, the LSI 9200-8e does not post anymore and it is not seen by the server. Everything else continues to work as expected, including UNRAID and the 1080 GPU. I can even see the 1080 GPU under UNRAID and am able to pass it through to a VM and it works. I tried moving the LSI card into slots 2 & 3 to see if it made any difference but I still get the same outcome. Any ideas? Do I have a conflict with the PCIe slots? How would I resolve this? Thanks. unraid-diagnostics-20220703-0936.zip Edited July 2, 2022 by Brenton Spear Quote Link to comment
