Ryzen board, no post

patchfile wrote: So the wife and I ordered parts from Newegg to build 2 Ryzen computers. We only use Asrock motherboards and Newegg would only let us preorder one of each board so we had to get different boards. Not a big deal, I got the Killer/ac and she got the PRO4. My parts all got here first and I am up and running with no major issues for the last few days. The PRO4 showed up yesterday and I put her computer together but it would not post. I spent all day on it. I tried different PSU's, GPU's, RAM. Put My CPU on her board and her CPU on my board, both worked fine on the Killer/ac but nothing worked on the PRO4. At one point I dug out an old motherboard speaker and plugged it in to hear the error codes and was met with silence. I even took everything off the board except the CPU and heatsink and still got no error beeps. Oh well, has to be a bad board, so I got an RMA number and shipped it back to Newegg. Fast forward to this morning and I get a call from my Brother-in-law who also ordered the same parts as me to build his new gaming rig. He also has the Killer/ac, and he is having the exact same issue as the PRO4, no post, no error beeps, nothing. I have been doing this for a long time, I built my first computer in 1993 and I build 3 or 4 computers a year for people who depend on me for tech support and gaming information. Having two boards from the same manufacturer both refuse to post or give an error code seems like too much of a coincidence.   I am wondering if there is some trick to these new Ryzen boards that I am missing. Did we just get super unlucky with two DOA boards? Or am I missing something? I appreciate any information you can share.

Unfortunately, the default setting for the Boot Beep option in the UEFI/BIOS, Boot screen, is Disabled.

So until you can get into the UEFI/BIOS and enable that option, you won't get any beeps from the POST beep speaker.   That is the default setting of the Boot Beep option of every ASRock board's UEFI/BIOS I have used.

That is a choice I don't understand, since having the POST beep speaker enabled when a board is used for the first time would be the most useful. We then have situations like this where the user reacts in the only way they find logical. I want to be clear that I don't blame you in any way.

Memory compatibility as a function of UEFI/BIOS support, which seems to be the case between the two boards (assuming nothing else is wrong, such as bent pins in the CPU socket with Intel systems, that does not apply here) remains a mystery to me. It is also something the user can do nothing about to fix on their own, short of a UEFI/BIOS update. That is, if they are able to do that.

We have struggled with DDR4 memory compatibility with the three earlier DDR4 compatible systems, Intel's X99, and their 100 and 200 series chipset boards. Ryzen systems have initially seemed to be even worse regarding DDR4 memory compatibility. That may really be caused by the existing base of DDR4 products being solely designed for Intel systems. Plus Ryzen is so new, we are still learning its memory compatibility requirements.

The bottom line regarding DDR4 memory is, we must be certain it is compatible with the system we have. When things like this happen, how do we expect users to react?

Welcome to the Ryzen thread 

Couls it be the PSU? It came from my old system AMD 990FX Fatality board. I'm lost..and I'm a retired Information technology guru :)

Bought the pwr sply 2/11/16. It is the EVGA Supernova 1000 G2 gold. With all the stuff I had hooked up, could I have overloaded the psu. I did a v & w count and thought I was safe. 

Just wanted to chime in and make sure people who are failing to POST have also unplugged all headers: HD Audio, USB 2.0/3.0.. anything not critical for system function.
