System:

AS Rock AMD B350 ITX/AC Motherboard

Samsung 960 EVO m.2

Ryzen 5 2400g CPU

G.Skill DDR5-3200 (16GB)

I'm unable to get anything out of the motherboard.  All it does is turn on the CPU and Chassis fans.  It won't POST or display anything.  It is labelled as being compatible with the 2400g and has a sticker on the bios stating a compatible p4.40 BIOS.   The only components that turn on are the case and CPU fans.

Everything was purchased from Amazon.   I've attempted the following.

- ordered a 2nd motherboard of same model.  Same results.  (both labelled as P4.40 Bios)

- tried resetting CMOS jumper

- tried resetting CMOS jumper for 4 hours as detailed in some other threads

- tried different monitors & HDMI cables.

- tried with all components removed except for basic ones, i.e. ram, cpu, m.2

- tried with different ram both 1 slot and both slots filled.

Any ideas are appreciated.

Thanks,

Ray

The psu is an FSP AURUM 500W 80 GOLD and the case is the Raijintek Metis Plus.  I've removed the power and connections several times on 2 separate boards with same results.  Things were properly seated.

The memory is not on the QVL.  Perhaps that is it.   I've ordered up some new ones that are listed on the Raven Ridge QVL and will go from there.  

I've gone with Corsair  CMK16GX4M2B3200C16

Thanks,

Let us know how it goes with the new RAM.

The new set of RAM is as mentioned above.  Cruicial:   https://www.amazon.co.jp/gp/r.html%3cC=21LZXCDLASPJD&K=3EISGN3IPFCRS&M=urn:rtn:msg:20180327081845484cc9b99e574d4583d2f88fa110p0fe&R=2CVZ9A0HHSLCX&T=C&U=http%3A%2F%2Fwww.amazon.co.jp%2Fdp%2FB0143UM4TC%2Fref%3Dpe_1807052_289327182_tnp_email_dp_1&H=XIVAJTS4WV97Z5N3CHAEMRD70BSA&ref_=pe_1807052_289327182_tnp_email_dp_1" rel="nofollow - CMK16GX4M2B3200C16

If there is a Raven Ridge BIOS version sticker on the BIOS chip and or board packaging, ASRock updated the BIOS. I have been assured this is the case by sources I trust. The only possible way that anyone can receive a board with a Raven Ridge Ready sticker on the box when the board has not been updated is in the case of a mixup with a return at the retail outlet in which case the serial number on the box would not match the one on the board.

 

I have been scratching my head over this one too. 

I have heard some users simply powered on the machine and left it powered and returned to a post screen. It my be worth trying. I would use a DVI monitor with adapter cable and give it a shot (this combo works most of the time in case the issue is the display output mode). 

If after 30 mins being powered up there is still not post, let us know. It may help to attach a PC speaker to the system and test without memory to see if you get the no RAM beeps. Turning off the post beep (set by default to off) does not effect error beeps so you should get something. Given this is the second board, check the serial numbers and see if they are close, if they are then they may both be from a bad batch (box dropped in shipping for example). From what I have seen boards are generally shipped in batches of 10 so this is a possibility. 

Stree's suggestion of disconnecting the M.2 is also a good one. Remove everything that isn't needed for post. Problems like these are a real pain. We will help you through it.

Thanks for all your comments.   

I'm going to let it run for an hour just to see if anything pops up as Xaltar has mentioned.

Cheers,

OK, so here is what we know:

1) 2 Motherboards, same issue

2) 2 Kits of RAM tested, one of which is on the QVL

3) No PC Speaker activity (even with no RAM installed?)

Logically, the odds of 2 boards being dead or for some reason not what they claim to be is exceedingly low, particularly given the variance in serial numbers (not same batch).

It's time to go old school on this thing.

1) Set up one of the boards outside the case on it's product box

2) Install a single stick of RAM in the slot furthest from the CPU

3) Hook up your power supply being sure you have an 8pin CPU power lead hooked up to the board, not a PCIe 8pin.

4) Make sure your PC speaker is hooked up

Test

If there is no life then remove all RAM from the system. If there is a beep code let me know, if not then try the other board in the same way. If both boards provide no beep codes with no memory installed then you need to try another PSU. Regardless of BIOS version, if you have no RAM and there is a pin compatible CPU installed then you should get a beep code. Before the board even checks the CPU the RAM must be initiated so no RAM - beep code.

If you do remove the CPU, make sure you check for bent/missing pins. Missing pins will be obvious, a solder pad with a nub in the middle of it. Blank areas are just unused pins not missing ones. 

Let us know how that goes and please feel free to ask questions if you want clarification on any of the steps.

- I had already both Motherboards outside of the case for testing purposes as you described in your last response.  

- The latest board, I did as you recommended and couldn't get it to beep with zero ram, 1 stick of ram produced same result. 

- Went and did the same to the first motherboard.   It beeped with no ram.   Finally, something.

- Put on the basic connections and it started to work.

- The ONLY different thing I did between the 2 boards was on the original board that was suddenly now working, I had accidently left the reset CMOS jumper set overnight.  Previously I had left it for an hour with no luck.   

So it is good that it is now working.  But, no idea why it suddenly sprang to life and displayed the same symptoms across 2 new boards.  Now I've moved on to a continuously crashing windows 10 OS while trying to run the updates and any installs.  

Thanks for all the comments.   

For the crashing, download the very latest installation media from MS and create a new install medium. 

Make sure you install with factory defaults in the UEFI (no XMP in particular)

Only have the OS drive installed during installation

Now we see what else is going on.

Wondering if I should grab each driver manually from the site vs using their supplied CD to get the latest stuff.   I've already updated the BIOS to 4.45.

Always download the latest drivers, the CD is just a coaster you get for free 

This does not happen with latest insider builds because they fixed the issues with Raven Ridge in them, official ISO's will become available next month, until then you need to update windows after install.
