ECC RAM not booting. I will try: - update BIOS - switch CPU To determine the issue. But I want to keep moving forward and test other components so I'm going to use my old non ECC 32 GB stick. Downloading TrueNAS SCALE ISO now... got ram working by plugging one in on slot A2, booting, then adding the other to B2. TrueNAS SCALE installed with web UI at https://192.168.1.140/ ECC confirmed in TrueNAS web ui. But I do want System is not seeing IBM Intel X540-T2 > You must assign an IP address to each network interface card (NIC) installed in your system if you want to communicate over your network using the interfaces. NIC was warm when I felt it, and now it's cold no matter what. I can: 1. Ensure drivers are installed 2. test on another mobo I didn't do above, but I did disable onboard LAN in BIOS and plan on reinstalling TrueNAS > `Add` is only for adding a Bridge, VLAN, or Link Aggregation interface. Not for adding a new NIC. I can also check BIOS for the NIC (advanced<"onboard devides" or peripherals) modprobe the ixgbe driver: 1. lsmod | grep ixgbe 2. sudo modprobe ixgbe 3. lsmod | grep ixgbe 4. ip link show 5. dmesg | grep ixgbe Force remove and reload driver - sudo modprobe -r ixgbe - sudo modprobe ixgbe > The Intel X540-Tx cards are old style cards that can only handle 1 and 10 GBit, which is less than ideal, because even if you need more than 5m of length, more often than not, you will find than 10 GbE does not work over older cabling, whereas 2.5 or 5 GbE does. Matter-of-fact, X550-Tx adapters can handle those lower speeds. Also, there are many mainboards and devices which already bring 2.5. GbE to the table. This implies the Intel X540-T2 cannot handle intermediate speeds. But how do VLANs come in? for Link Speed Negotiation, I may need Intel X550-T2 () or Chelsio T520-BT, but Mellanox ConnectX-3 Series could also work. But the intel is the only that supports 2.5. Intel i225-V/i225-LM. Check for hardware revisions (prefer rev 3 or later) to avoid earlier versions with potential stability issues. https://archimago.blogspot.com/2022/10/aquantiamarvell-aqc107-10gbe-network.html > The X550 is mainly desirable because it supports 2.5/5g in addition to 1 and 10g, which the older X540 does not. Paid $161 for Intel X550-T2 I returned the old NIC. --- sda: ZVTG3ZWM sdb: ZVTG3ZLW sdc: ZVTFE2PB sdc: ZVTG3NVR sde: ZVTG3PVM
