Nevermind i got it. I didn't think about jumpers at all, it turns out that the jumpers were misplaced. Once set up correctly, everything works as it should.
Hello everyone again, so i have R920 server, i have 4CPU's, 8 Memory cards (but use only 4 for example) and the problem is server cant boot. At first on display appears "Configuring Memory..." after one minute appears "...Done"Screen gets black and the PSU fans stop rotating. VGA-signal gets lost with no error message.Only LEDs on board keeps blinking. So I can't enter bios or iDrac.Anyone can tell me what can be the problem?
