What does the error 'CPU 1 VCCIO PG Voltage Is Outside of Range' mean on a PowerEdge R760?

This error is typically associated with issues in the motherboard's voltage regulation or CPU seating. To troubleshoot, perform a power drain, check for firmware updates, and inspect the CPU for any bent pins or debris. If the problem continues, the motherboard may need to be examined. [community thread]

Why does the iDRAC display CPU speed in MT/s instead of MHz or GHz on my server?

This is a known presentation error in iDRAC9 where the CPU speed is incorrectly labeled as MT/s instead of MHz or GHz. It does not indicate a hardware or firmware issue, but rather a unit-labeling mistake in the user interface. [community thread]

Can the R760 server support two Nvidia L40 video cards?

Yes, the R760 server with dual CPUs can accommodate two Nvidia L40 GPUs, as they are double-width and within the power specifications. Ensure you have a power supply of at least 1600W and the appropriate GPU riser kit, power cables, and cooling components for optimal performance. [community thread]

What do the LED codes on the R660 motherboard indicate when the server fails to boot?

The LED codes on the R660 motherboard can signal various issues, such as a 5V switch fault or problems with connected USB devices, iDRAC cables, or the rear I/O card. To troubleshoot, perform a flea power drain, clear the NVRAM, and test with only the minimum components necessary for POST. If the server still does not boot, further inspection of the components may be required. [community thread]
