[Problem solved: see below. In short, x470 needed a firmware upgrade to support the 3600. The red LEDs for the DIMM are designed that way and do not indicate a problem]

Hi, everyone. Just put together a new build using logicalincrements.com's "Good" build. I don't get any video signal and I have the CPU and DIMM led's lit on the mobo. More troubleshooting steps below.

CPU: AMD Ryzen 5 3600

GPU: ASUS GeForce GTX 1660

Mobo: MSI x470 gaming plus max

RAM: 16GB G.Skill Ripjaw v series (2 x 8GB)

SSD: 512GB Intel 660p M.2

Power: EVGA 500

What have I done? I've reseated every single part twice (DIMMs, CPU, GPU, all Mobo power, fan, cpu cable connections). I've tried booting with just one dimm or both, no difference. DIMMS are in slots 2 and 4. GPU is in slot PCI_E1. SSD is in M2_1.

What happens: when powered on I get three red lights on the Mobo (one for each DIMM, one for the CPU). All fans are on and I have power to the GPU. My monitor does not get a signal from the GPU. I've used HDMI and DP. I've tried the MoBo HDMI and no matter what I can't get a video signal. Is there anything obvious I am missing? Do you need any more information?

Thank you in advance!

I feel your pain. I too am dealing with this board in a new build. The DIMM LEDs are supposed to light up. The CPU (I assume the EZ-check) LED is not supposed to light up. When I had this issue, I discovered the reset switch on my case was stuck in the engaged position. I disconnected it and it fired right up. (Unfortunately, the board now exhibits VGA errors....sigh)

Thank you for your reply. I'll let you know if I solve it. Also, thanks for the DIMM LED info, I suspected that wasn't a problem but wasn't sure.

The debug LEDs light up momentarily, but if they stay on solid there could be an issue.
Unplug the system and try JBAT1 (clear CMOS).

Is your RAM kit a new purchase or used? Have you tried cleaning golden finger, boot with one stick of RAM and swap slot 2 and 4?
Also, is there any CPU bent pin?

Hello - thank you for your reply. First, the lights on the mobo for the DIMMS are designed to indicate that the RAM is recognized. So, that is not a problem. Why they use a red LED to indicate a problem (the CPU), as well as the existence of RAM, doesn't make sense (at least use a green light!).

Next, the CPU light went away when I installed a 1700 CPU. Then I was able to get video and update the BIOS for the 3600. Even though the x470 was supposed to work with the 3600 out of the box, it didn't.

Problem solved.
