[SOLVED] Yellow DRAM lights, no beep codes

[shorty02]

Just built this rig, but I'm getting a consistent DRAM light with no video.

Board: Asus TUF Gaming x570 Plus
Ram: G.Skill Ripjaws V DDR4 3600 (F4-3600C16D-32GVKC)
CPU: AMD Ryzen 9 3900x
GPU: ASUS ROG Strix 2080ti

I've also added a small beeper to notify of any beep codes. I'm getting none. (Removing RAM sets it off so there's no issue with the buzzer)
Can't get any video output so can't update BIOS or do much of anything. I've pushed in the RAM pretty hard so it should be seated properly.

Does anyone have any ideas?
Thanks

Try one RAM module on slot A2 (4th from CPU) and see if the system posts.
Make sure the RAM is installed on slots B2 (2nd from CPU) & A2 (4th from CPU).

I've tried A2/B2, A1/B1, 1 stick and 2 sticks, in either config. Wouldn't I get some sort of Beep code if it the DIMM slot wasn't working?

The motherboard does a hardware check and the onboard LEDs will remain lit if a problem is found.
BOOT - Yelow green
VGA - White
CPU - Red
RAM - Yellow

To hear a beep you would have to install a 4-pin speaker.
That won't help, since you will hear the beeps codes for a RAM issue.
Make sure your CPU is installed properly, since it could also lit the RAM since the RAM controller is on the CPU.
Also check the the 8-pin and 4-pin ATX 12V CPU connectors (from PSU) are seated correctly .

I have a 4-Pin Speaker installed.

CPU Connector: I have the 8pin in. Don't have the 4-pin in since the previous mobo I had didn't have a 4-pin CPU PSU Connector.

Not sure how I would check to see if CPU is installed correctly. Not sure how I would install it wrongly to begin with. The CPU is in, locked in place and a cpu cooler on top of it.

I started having the same issue with a previously working X570 plus wi-fi, Ryzen 2700X, 2x Corsair V LPX 3600MHz 16 GB setup.
The issue started immediately after BIOS update to build 1407 (previous one was 1005).
There is the yellow led with no beep and no way to boot the system. Clearing CMOS had no effect.
Something worth to turn to ASUS with? Should I happen to get my problem solved I will post back here.

For AMD Ryzen 9 3900x, you might need both, the 8-pin and 4-pin ATX 12V CPU connectors or the system might not boot.
A resent and adequate PSU for your system should have those connectors.
I got a couple of inexpensive 750W PSUs and they both had 2x 8-Pin (4+4).

I've seen a few posts saying they've used this board without the 4 pin connector fine.
Will attempt using the additional 4 pin connector and report back.

Tried with the 8 & 4 pin CPU connectors. Still no luck.
Don't have another CPU that's compatible with the MOBO so I can't test a different CPU.
Open to any other advice before shelling out more money on a CPU that may or may not solve the issue.

I think they dont refund cause you updated bios, not sure though worth a try. Your model has 32mb flash file, do you know exact bios chip model maybe you can try flash to chip with SOIC clip? Just read from the chip with magnifying glass

You should try another PSU.
I was just building a similar system and was having the same issue.
I was using a Corsair 650W PSU.
I have used many Corsair PSUs and this is the first one that was faulty.
Just swapped the PSU and the system booted up.

Thats good idea, my comment was for "hiltz" situation

Issue was the CPU.
Dunno why it doesn't work. But went and bought another Ryzen 9 3900 to trouble shoot.
Boots up perfectly fine now.
