VGA LED stays lit even when you remove GPU and connect monitor to motherboard? Is it new build or was it working before and suddenly stopped?
Check the CPU socket for bent pins.

Its a brand new build and ive alread rma the board and they sent it back saying nothing was wrong.

Then only thing left is CPU malfunction. While it makes no sense at first look (why VGA led and not CPU led?), however note that both iGPU and GPU are CPU-dependent - iGPU is built in directly into CPU, and GPU uses CPUs HSIO lanes to work.
But just to be on safe side, as you did not mention trying other RAM, are you sure you got RAM compatible with your motherboard?

Yes ram is ddr4 and the mobo is ddr4 so what would i have to do with cpu rma it or?

If that was that simple. There are ECC, non-ECC, registered and unbuffered versions of DDR4. Your mobo supports only non-ECC, unbuffered DDR4. If you got any other, it might not work.
As for CPU, I see no other option then to RMA it (of course assuming RAM is not problem, again).

Yes ther ram is also non ecc
