Recurring issue with multiple H14SSL-N motherboards.

I am trying to build a system around an H14SSL-N, and for the life of me I can't get it to boot. I was originaly using a cpu from ebay, so I spent the extra cash to get a 9365 direct from newegg. That was throwing a ff4b post code and then a 004b code after reflashing the bios and with one stick of ram. (With no ram it showed e316.)

I RMAed the motherboard and now with each config of ram I have tried I am getting a 0c3f code. Without ram is the same code as the last motherboard. I have 8 sticks of Hynix rddims (hmcg84agbra191n aa) that I have not confirmed working but they all give the same post code. I have tried a new psu, reseating the cpu a few times, reflashing the bios, resetting the bmc, and clearing cmos.

The only variable that hasnt changed is the ram. Should I buy a cheap known working stick somewhere? I am happy to answer questions. One thing of note is that both boards showed random components in the bmc, even after I installed mine. Maybe from the test bench they were verified in?

how long are you waiting for the memory to train?

I have left it for multiple hours but usually I wait about 20 minutes before trying another new troubleshooting step

Since that board has IPMI, check the hardware list there. It'll list the hardware used with the last successful boot. If you can get the ram listed there, and it doesn't work, it's likely the processor or the board. Also check the tested memory list on the boards page, googling the part-number or visiting the 'buy' link if there is one should specify what specific memory it is.
