I would like to know if the Dr. Debug error codes that I am seeing when I turn my new PC build on are normal, or if i need to RMA the board...

The video of the error codes may be found here: https://www.dropbox.com/sh/f8lr25qi3tqqszs/AACnel7JdHPvwcft_GamKqxua?dl=0

I could not list them all here if i tried.  They flash to quickly when i first turn the computer on.  they go away completely when i am in windows, and everything else seems to be working normally.  I just dont want a defective motherboard later down the line...

My Build Specs:

-CPU: AMD RYZEN 1800x

-RAM: 64 GB G.Skill Flare X 2400 MHz DDR4

-CASE: Silverstone FT-02 No Window

-MoBo: AsRock Fatal1ty X370 Professional Gaming

-CPU COOLER: Noctua NH-D15 w/ AM4 bracket ASSY (with only 1 Noctua Fan installed due to clearnace issues)

-FANS 1: (3) AP181 180 mm Air penetrator

-FANS 2: (1) Exhaust fan that came on the case

-PSU: Seasonic 850 W Modular

-HDD for Main OS: Samsung 960 EVO M.2 500 GB

-HHD (Currently Unplugged right now but will be needed): Seagate 3 TB secondary HD from my older PC w/ all my files

-GPU: Radeon HD 4850 (I know its super old.  Waiting for vega maybe not sure yet :P)

This is perfectly normal. The Debug LED displays what part of the post process is currently occurring, there are numerous post tests that happen every time you power the system on or reset, each of these has a code that will be displayed. So when the system freezes during a particular test the code will remain on the display and give you an idea as to what test failed and what it was related to. It is a very useful troubleshooting tool 

What does "PO" without the quotes mean? Thank you.

Sys specs:

Ryzen 1700 3.0 Ghz (OC 3.7)

Fatal1ty Professional X370 mobo

32GB (4x8GB) Corsair Dominator 3000Mhz sys mem - Memory code: CMD16GX4M2B3000C15

2x GTX 9704GB gfx boards running side by side no SLI

I have tried...

Checked all cables, especially the main motherboard 24-pin and the 8-pin CPU cable. The gfx board, (single now) which I'm using for testing has all power connectors correct. All of lights (the stock cooler and sys fans) glow nicely and all the fans are powered and spinning.

I have even tried running the sys memory in 1A 2A format so that only 2 modules are in (2x8GB) = 16GB and still the same error message.

One last thing, when I remove all the memory the mainboard continuously changes error code numbers so I know that it detects the memory when I plug it in correctly as it stops on 'PO'.

Any ideas?

Ty very much.

Hi Datonyb,

Thank you for your message. Answer #1: This sys has not booted before. This is the 5th, maybe 6th cold boot so far since finished built a few hours ago. I have done as you've asked, and please correct me if there should be a different basic configuration:

Gfx card (single) the second one removed completely in the PCI Ex slot closest to the CPU. That is Slot #1 I believe.

1x single 8GB RAM module installed in the 2nd to furthest away from the CPU in Slot number 3 (of 4), and that I believe is slot A2.

I have waited 5 minutes on a timer to post this reply before confirming if I have POST or no POST and the answer is still no CMOS POST.

The mobo reads: "PO" as before. Monitor tested? Yes I have a 2nd PC here on standby, the (work laptop) I'm writing from, and the monitor screen works just fine when plugged in.

Ty for additional advice you Awesome Fans of Fatal1ty Motherboard line-up! I cannot wait to finally get to CMOS...then installing Win 10 Pro x64.

I have checked my clock and its reading about 6 minutes in PO-mode now, and so I'll hit 'Post reply'

"0d" Does that mean 'Zero DDR memory found' ?

I think it could be that this RAM is not compatible with the factory firmware of the motherboard. Would a company affiliate like to comment to help me out? If need be I'll buy a known compatible RAM module such as the G.Skill 16GB (2x8GB) DDR4 2400MHz CL15 Flare X memory to boot it then update the firmware.

Would someone like to give a 2nd opinion on this idea?

Thank you.

Following your instruction as exactly as humanely possible:

1. The PC was off when I woke up this morning. I removed the power cord from the wall, the Corsair PSU I use has a switch so I switched that to the O position.

2. Held my power button down for at least 10 seconds and pulled the CMOS battery while holding it down, and then let go of the power button.

3. Timing the CLR-CMOS jumper on a seconds wristwatch I let it be in the 'reset' position for 60 seconds and then back to normal position. I want to add that I did not put the Clear CMOS jumper back in the original position until after I put the battery back in. Hope that's fine.

4. After 1-3 I did your exact recommened steps for the memory: A2 and B2 slots only with firm (two) clicks. I've built many machines, but yes thanks. So that's just to be crystal: The 3rd slot away from the CPU (A2) and the closest slot to the CPU (B2) on my 4-slot DIMM mainboard.

I have now powered up after checking all power cables to the now single gfx board.

"0d" in a solid state after about 30 seconds of the mainboard running tests.

I wanted to add that when this system was built, as with all systems I've build in the past I always used an ESD band and protect all the parts with care. I have used a small dab of Arctic Silver 5 thermal compound on the CPU so I think everything is in order with the hardware.

This must be RAM-incompatibillity. Would you like me to buy a 2x of Flare X? 8x2=16GB memorycode: F4-2400C15D-16GFXR

Everyone who gets Ryzen always gets POST with that here in Stockholm.

I was thinking I could buy that and if I get post update the firmware, as this is factory firmware out-of-the-box.

Edit: This is my first Ryzen build in life. Feeling nervous for no reason at all.

Gfx card on closest slot to CPU

Reset CMOS again in off position - waited 30 seconds this time (Its enough) back in normal position.

Unplugged the cursed thing.

Re-plugged the cursed thing.

I called my local computer chain called Inet and they offer two very good solutions: #1 I can order the Flare X online and they will refund me if I return it within 14 days. The second choice is I can leave the rig at their local shop and for a small cost they will POST it with their own modules, and install my modules for me with the updated BIOS. The second solution is something I'm seriously considering trying as I have to work today (like many people) and frankly I don't have 3 days to spend on setting up a POST.

Edit for emoterage calmness:

I have built Intel and AMD systems for over 10 years and this is my most difficult challenge.

In your opinion, dataonyb, should I order some 100% returnable without cost RAM or should I leave it in the workshop for support? They told me they will give me POST and I just pay the small amount for their update of the firmware (If its not another issue).l
