I was using a DH87MC mainbord with 8GByte for a while without any problems. Now I would like to upgrade to 16GByte. Therefore I have added two DIMMs, which are identical to the old ones. With this configuration the system does not start anymore. After switching it on, some seconds later it switches off by itself. There is nothing on the screen and no beep. The new RAM is OK. I can choose any two of four DIMMs and any two sockets and it works. With four DIMMS it does not work.
RAM: 2 pairs of Kingston KVR1333D3N9K2/8G
BIOS: current (0158)
what can be the problem here ?
I hope, that someone can help me.
thanks in advance
Have you tried another power supply? This is often overlooked as a troubleshooting step, but if you already tried this or if you still have the same problem after trying another power supply I would suggest that you contact Intel customer support since you may have a hardware issue.
