Thanks Ssathenth, made sure the after splitting the the second  4+4 plug that it read CPU on the molex plug before plugging into the board. 

We have been up and running for two days now. I did a four our stream last night with no issues. 

So, hopefully we should be in business going forward.. this thing is a beast!


Cheers,
Scott

The 8 pins on your PSU are for CPU -and- PCI-E. Make sure to use the right cable for plugging into your board, but plugging PCI-E cable and CPU cable into any 8 pin on your PSU will work. The 6 pin on PSU are only for sata and 4pin molex.]]> Mon, 12 Feb 2018 03:11:50 +0000 https://forum.asrock.com/forum_posts.asp?TID=7617&PID=45014&title=x399-tahichi-power-connections#45014 <![CDATA[X399 Tahichi power connections : Ok, Bios 2.0 definitely fixed...]]> https://forum.asrock.com/forum_posts.asp?TID=7617&PID=44948&title=x399-tahichi-power-connections#44948 Author: loooper15

Ok, Bios 2.0 definitely fixed the m.2 boot issue. Installed the drive, rebooted no issues. 


Well, I guess we will see how it goes...

Ok, well, here is what we know right now haha..

If I plug the 4 pin CPU in the "correct" way the latch at the top of the board, no boot, no post, no fans, nothing nada.

If I plug it in like as shown in the manual, turn 4 pin connector 90 degrees to the right, latch on plug now on the right side of the motherboard connector, volia.. it boots. 

Current CPU voltage at idle .850
Tdie a nice 25c

I believe another issue I was facing was with the m.2 drive installed it would loop forever, I found another thread stating this was a known issues with older bios. 

I have updated to 2.0 and am currently putting in the m.2 drive to see if she will post.

OS is currently installed on the older traditional SSD Crucial m4 drive.

MisterJ, thank you very much for help and guidance on this adventure haha :)


Thanks!

I never heard such and am not sure I believe it.  I assume if you plug it back in, you will boot as long as the offending SSD is out.  Obviously you can boot without it, but I would not run without it - perhaps causes droopy core voltage.  We do not know your setup.  Please post your specifications.  I prefer them in you signature as mine are.  Did ASRock comment on the 4-pin orientation and version number?  Good progress, though.  Enjoy, John.

Ok, more to the story. Removing the 4pin by itself didnt let the board finishing posting. Then I was looking at everything for the 1000000 time and decided to remove the m.2 drive from  m2_1 slot..... boom went to bios..

further testing moved it to m2_2, no bios... didnt try m2_3. 

I had another SSD on the traditional sata connection, left that connected and now installing windows 10 on that drive.

We will straighten out the SSD etc as we go... 


Thanks for all the responses... wonder what we should do with this empty 4 pin slot hahah...

Ok, got this response from a tech. 

The 4 pin connector is for over clocking the CPU and is not required for boot.


Hmmm

MisterJ, Yeah, looking at the boards on different sites, the latch is definitely different. I did get a response from tech support and I asked about the latch and sent a picture. Even in his example pictures it shows the latch to the right. Now I know this could be a version change.. but we will see.


Thanks!

loooper15, I know it says technical questions cannot be answered here but if it were me, I would call 1-909-590-8308 in the USA and scream.  Can you go to a store and look at another board close by?  Good luck and enjoy, John.]]> Fri, 09 Feb 2018 03:43:29 +0000 https://forum.asrock.com/forum_posts.asp?TID=7617&PID=44860&title=x399-tahichi-power-connections#44860 <![CDATA[X399 Tahichi power connections : Thanks MisterJ, much appreciated!I...]]> https://forum.asrock.com/forum_posts.asp?TID=7617&PID=44858&title=x399-tahichi-power-connections#44858 Author: loooper15

Thanks MisterJ, much appreciated!

I have a ticket open with ASRock. But not sure as it states to go through the reseller first.


We will see...
