I replaced my MOBO and CPU today with a i9 7980xe and Rampage VI extreme with 64gb of ram. I spent time building it today and when I finally plugged it in it turned on straight away, the lights on the motherboard turned on but nothing else. The power button wouldnt turn it off either. Any ideas?

Sorry for the late reply.
It could be a bios issue. According to the manual, your motherboard comes with 2 bios chips, which you can switch with the "BIOS_SWITCH" button in the bottom-right corner.
You can also give the MemOK button a shot. The manual covers the various on-board buttons and switches starting from page 1-9, for further reference.

Could be a driver/BIOS problem. Try to flash the CMOS to see if that works. You'll also have to buy a new Windows license (if you want your windows activated), because you've switched your motherboard.

First, make sure you plugged in all the cables. Try reseating the memory and/or booting with just one stick.
Do you get any error lights/beep codes?

My bad, I should have asked how many sticks of ram you have in the first place.
Your motherboard supports up to 128 GB of ram having 8 dimm slots, so max. 16GB/slot. So one 64 GB module isn't supported.

Yeah I have 4 16gb ram modules installed in the corrected dim slots too.

Oh, sorry for misunderstanding.
If the memory is working and installed according to the manual, then the issue might realted to the graphics card. Have you tried another PCIe slot? Or connecting to a different graphics port?
For non VESA-certified DP cables there is a issue with the pin 20 (may or may not be your case).

It could be. You might want to test the power supply (just to be sure) or to reseat the cpu.
Also, try to resetting teh cmos once again. You should press and hold the button for a few seconds.

Yeah I have the PSU running in another PC at the moment aswell, do you think it could be a bios issue?
