so.. I just picked up a r710 from ebay and I got it running and tested some stuff al working great. I installed esxi 6.0 with the drivers from dell and I looked around for a bit and decided to upgrade to 6.5 by the ssh terminal.
After that finished I rebooted and man did it take long to boot. First I waited like 30 mins on the "booting eufi please wait" screen and then it got stuck for like 2 hours on the "Entering system services... Starting unified server configuration" screen and I decided to shut it down. After more atempts to get it working (didn't change anything) just trying to install another os i began getting ram errors "membist failure" and i got only 36GB ram left. Then I also saw it was only running at 800 mhz.
What is going on?!?! can somebody tell me wat to do?
