Hi Roy.
You said that you met a ram error,maybe you didn't insert the dimm in a correct slot.
from a pdf file the memory load order is as shown.

Thank you  for your advices about  the fan  connector. Maybe we have different definition of the first pin .May be we just counted from opposite side.

Do you  use  reg  ecc  ddr4  memory? It  seems that only this kind ram can be used on  the board .

As I have learnt, the p1 connector pinout should be as shown,but I need your confirm.
The 10、1 Pin is output for 5V equipment like sata from VRMs on the motherboard.
The 16 pin is a POWER_GOOD signal,which trun to HIGH when the PSU finish startting period.
The 17 pin is a 5v stand_by voltage which is different from z420's 11V.
The 18 pin is a negative 12V input for RS232.
The 8 pin is PS_on,connect this pin to groung will trun on the PSU.
The 9 pin PSU_ID tells the motherboard which psu is installed ,it is different from standard ATX psu.
If you have oscilloscope or logic analyzer, please capture the waveform of PSU_ID.
Thank you!

Thank you Roy.
I think the 6-pin fan's pinout  is connecting 6.5.1 together as groung, other pins are like generic 4-pin fan.
Because of Chinese Spring Festival I can't test it in about 10 days.
We can communicate with each other with a instant messaging software.
As for power supply I want to use a server psu DPS-800GBA so I don't want to use that adapter although that seller is close to me.
Thank you for your pinout again.
Here is a photo of the orignal fan from Taobao.

I just bought this board a few days ago.By measuring the impedance of pins from the connector , I guess the pinout is as shown in the attachment.But I cannot confirm that.So, your measurement will be the final result.
Finally, Can you share the pinout of  24pin-to-18pin adaptor?
