Question X10SLH-F + e3-1271v3 + 4x KVR16LE11/8 - the 2008 starts successfully in a safe mode - the 2008 starts successfully if I limit the number of processors to 7 or less - the 2008 reboots just at Ctrl-Alt-Delete screen and the LED at LE6 on the motherboard comes red if all 8 cores enabled Answer For LE6, the light meaning as follow: Green means all onboard powers are ready. Orange means standby power is OK but not power on yet. Red means some onboard power has issue. Please help to update the latest BIOS ver. 4.424, and IPMI FW R1.42 which solves some memory compatibility issue ; and change a larger PSU for testing. Was this FAQ helpful?
