cant reach IPMI. MB powered on for about 30 minutes and I watching DHCP on my router and dont see any new devices. green and yellow leds near IPMI LAN connector are blinkin
cheap E5 v3 already ordered. going to buy cheap 4-8GB DDR4 2133 ECC REG.
IPMI: So, you mention above that you just bought it used. Could the IPMI have a static IP set that is in a range outside your network? The last few boards I got (all from the same source) had static IPs in in the 0.0.0...., which didn't initially show up in my 192.168...& 10.10.10... setups.
Of course, resetting that is gonna be hard if you can't boot enough to set a new IP via the BIOS.
As for booting, sometimes with those big(er) sockets, reseating the CPU helps to fix memory issues. You can have a system that boots most of the way, but then throws a memory error due to a mis-seated CPU (ask me how I know
). 2011-3 isn't as error prone that way as LGA 3647 & other gigantic sockets, but it happens. If the board came to you without a CPU (and you haven't already) maybe also examine the socket really closely with a light for bits of TIM tucked under pins? It probably isn't conductive, but if its a hard bit a pin could deflect under pressure and short against its neighbor. Then when you pull the CPU it springs back and looks totally normal. Not that that has ever happened to me and lost me a half day of testing or anything...
