We have SYS-2027GR-TRF (X9DRG-HF) that has 4 PHI cards (5110P) in it. It will not see all 4 PHI cards. In fact it’s pretty inconsistent how many they see. Sometimes it sees 1 sometimes it sees 2. Also the 2 on the left (CPU 1 side) seem to get very hot. Any thoughts on this?
Please go into the BIOS:
Advanced -> Chipset Configuration -> North Bridge -> Integrated IO Configuration, please see what PCI-E speeds the slots are set to. If they set to Gen3, please switch this to Gen2 to see if the issues persists.
If this does not solve the problem, please submit an issue using the following link: https://webpr3.supermicro.com/Support/login.aspx?
