X370 Taichi crashing on stock settings and C6

Just picked up a 2700x and had the same issue with 1700. I'm using the latest 4.60 bios. For ram, I'm using G.SKILL F4-3200C16D-16GTZ.

I'm wondering if C6 and Global C-State are the same things. What ever documentation I can find is very bad.

What ever documentation I can find is very bad.  I'm worried it could be a hardware fault since another person with similar spec don't have any problems with C-state enabled. My next suspect would be my RAM. Off the top of my head, I manually set the clock speed of my 1700 to 3800, fixed voltage of 1.3v, fixed Soc of 1.1v. I had both LLC at Level 3. Keep in mind every chipset is different so the exact config may not work for you. The general idea is that I'm manually setting values and I assume when I manually OC all those nice little features, like C-States, are disabled.

just a quickie as my dinner is served

but 1700 at 3800 with 1.3v is on the low side for that , that may be an issue

ah, I forgot to mention that I tested my RAM with Memtest for about 1.5 hour, and no errors were found. It might not be enough to conclude anything, but that's reassuring nonetheless. Also, when I experienced my crashes, they weren't the same as you ricestream : instead of getting a black screen, the first time, Windows froze completely (the HDD LED was still blinking from time to time, but I had to press the reset button), the second time (Windows), it made a blue screen and rebooted, and the third time (Fedora), it was a random reboot as well, with an "hardware error" message in the logs.

I thought about something : could it be possible that due to the "silicon lottery" you mentioned, the default/auto settings of the X370 Taichi are not enough for some CPUs that need a bit more voltage to function properly on idle (not sure whether this would be considered a hardware defect...)?

@datonyb : I have been afraid to change the RAM settings because I'm not sure if I need to change other voltages at the same time, such as that of the SoC. And I use this machine for my work too, so I'd rather have it slower than unstable :) Because I've heard that 2933 MHz doesn't bring much over 2666 MHz, wouldn't it be safer to try that? The problem if I want to try such a frequency is that then, I have to set the voltage myself, don't I (because IIRC, there isn't an XMP profile that I can choose for lower speeds)?

I would be interested in swapping parts to see if it changed something, but for me it is a difficult thing to do, as building PCs makes me very nervous, and I have a physical disability which makes it even more difficult (couldn't build the computer without help, and the people who helped me don't have much time anyhow). I could probably test another GPU on the Taichi, but not the GeForce 1070 in another PC, because I don't have another machine where it would fit. I also don't have another PSU available. My current PSU is a Corsair RM650x. As to the storage, I have a simple Sata mechanical HDD, which limits the problems on that side I guess (since I've seen people whose crashes were actually caused by SSDs)

Sorry about that, I generally pay attention to this kind of thing. Edited my message
