X570 PRO4 AM4 CPU and DRAM LED's on

Hello all,

I have a new build using this motherboard, a 3700x, 2070 super, 2x 16 gig DDR4-3200 Corsair Ram, and a 750 corsair RMX 750 PSU. I plugged everything in, and it all turns on and everything lights up, fans spin, etc. But the DRAM and CPU lights on the mobo are a solid red, there is no image on my monitor, and the computer resets every ~10 seconds. I have tested what I could in my old computer (PSU, Graphics card) and know it isn't either of those 2 parts.

I also tried taking the motherboard out of the case and using the bare minimum of just the mobo, PSU, GPU, CPU. No fans or anything and still get this issue. Tried cycling my RAM through A1, A2, B1, B2 with both sticks. Cleared CMOS too. This is the second ASROCK X570 PRO4 board (the first was DOA). Did I simply get a dud again?

Just btw the corsair ram model is CMW32GX4M2C3200C16W, this is the same as the CMW32GX4M2C3200C16 listed on the approved ram options it just has W at the end to indicate it is the white colored ram, but the same model

Thanks

The odds of getting two dead boards are slim to none. ASRock tests all RMA replacements before shipping them out. Generally speaking, if 2 boards don't work in a row, the issue is somewhere else.

By the looping it sounds like RAM training that is failing or incomplete. Sometimes you just need to leave the system powered on for 20mins (it should POST a lot sooner but 20mins is a good amount of time to be sure it isn't going to). If after that you still don't get POST then see if you can try some different RAM. Zen 2 is better than it's predecessors with RAM compatibility but it isn't perfect.

having the same issue did anyone ever figure it out? i RMA'd my last motherboard thinking it was that

Got the same problem, solved it after puching ram just a bit further into slot.

I got a couple fix's that I had to do before it would even post. I'll walk you through it.
