I am having a dumb problem which I cannot solve as I am out of ideas. Got all new components for a new PC 2 days ago and cannot get it to work because the motherboard seems to either be broken or incompatible with my CPU. The CPU is a i7 3770k with the new 28nm fabrication. I tried 2 sets of Ram, the one is a Corsair Vengeance DDR 3 PC 1600 with standard latencies and stuff and the other one is Kingston PC 1333.
The problem is following: the mainboard indicates via 4 short beeps that a hardware component is broken and the DRAM LED is lighting red, which indicates a RAM failure. However now that I tested 2 sets of RAM in various slots and configurations and having made sure that CMOS was cleared, battery removed and MEM OK button pushed (lets the mainboard test varios speeds and compatibility with RAM) I can now safely assume that the problem is not the RAM.
I can now only think of 2 things: either the mainboard southbridge/RAM controller is broken or the CPU is the problem, because its a very new one and the mainboard might not recognize it, though it is listed as compatible. In the handbook there stands that CPU's until 32nm are supported. I do not know however when this was printed and maybe it only affects the earlier revisions.
I cannot access the BIOS because it shuts down before it gets there, otherwise I would have tried to flash it. I also tried everything else to eliminate possible problems: tried another graphic card and HDD, made sure that all cables are inside their slots etc. I cannot test the CPU because my old board is not compatible with it.
Is there anything else I could try before sending the mainboard back? Im gonna call support tomorrow but maybe you guys have a clue what could be wrong?
