Taichi Ultimate, no post, code 3E, 15, 67

Hello,

I Recently purchased new MOBO. x470 Taichi Ultimate
Completed installation and plugged in power cord.
Computer turns on automatically and gives code: 3E, 15, 67 then dies.

Specs are as followed

CPU: R5 2600X and R3 2200G
GPU: EVGA RTX 2080 TI Black
Memory: Trident Z RGB 16 GB 3200 CS 16
Storage: Samsung Evo 970 500 GB & Crucial MX500 2 TB
PSU: EVGA 850 G3


Troubled shoot by:

Removing ram and only booting with 1 stick.
Removed and replaced CPU with R3 2200g
Removed CPU fan to have easy access to replacing of both CPU
Thoroughly visually inspecting both CPU for bent pins, none found.

I did notice that in removing the CPU from the socket, there was an unusual click before the lever is in the full upright position.

Check EPS cables and swapped 4 pins EPS around in case one wasn't the right one.

All different variations gives same codes and computer still attempts to start without pressing power button.

I was never able to reach the BIOS since the computer dies after code 67.

I'm really at a lost and am not sure what to do next.

It could be the ram.

I did transfer over the ram from an Asus x470-i motherboard and it worked fine there.

Is it normal for one ram kit to work with a certain brand of motherboard compared to the next? I know that there are "AMD" ram kits but I had this ram kit from before and figured i'd use them.

DDR4 RAM is tricky to navigate. There are many different kits that are not on QVLs that work perfectly fine and there are some that simply won't allow post. It is very much a hit and miss scenario. Things have greatly improved since AMD launched the AM4 platform but there are still a few RAM kits out there that simply won't work with it.

You are correct, the W denotes the color variant of the RAM. As for LPX kits, I have used 2 different LPX kits on my X370 Taichi without issue but I have seen a few reports on the forums using other LPX kits that didn't turn out well. Both my kits are older and no longer available new so I won't list their part numbers. The kit you found is on the QVL so it will work but, if you are looking for a cheaper option, bare in mind you can also check the QVL of the RAM itself, so long as AM4 boards are listed for the kit it should work fine. We see a lot of people having good luck with GSkill's Flair X RAM kits as well as their Fortis line on the budget end.

Good luck and let us know how it goes

Kshendel, I have seen numerous people have issues trying to use Trident X RAM with Ryzen (AM4), here and on other forums with multiple brand boards. I will always be honest on these forums, if I suspected the board was at fault I would have immediately recommended an RMA.

If only that were always the case, we would get a lot fewer threads like this The issue is that the fail safe defaults are determined by the RAM's JDEC information not an industry standard. In other words, if the RAM in question has a default JDEC of 2400 or 2666 and the system is unable to post with those settings you are out of luck. In some cases, if you install a different RAM module that is able to post you can manually set the frequency to 2133, save and exit then install the troublesome RAM. After all that it most often will post but is still unable to run at anything beyond 2133 without extensive tweaking and messing about. For the average user this is impossible and for most more savvy users it is simply unacceptable to spend money on something that does not function as advertised. The only time I would recommend the workaround I mentioned is in the case of a user being unable to return the RAM for some reason.
