1800x & x370 Taichi Freezing issue

my taichi will downvolt to the 0.400 range

with c6 disabled

i presume the global c states is doing that as i leave that enabled

i use the ryzen power plan

maybe worth a try
but bear in mind im on bios 3.1 and have no need to use a later bios

Hi John. I'm running 4.40, because 4.41 is still marked as beta and i'm waiting for more feedback on it.
The memory is running fine though. Memtest86 with no errors for hours. Memory usually fails when stressed, but in my situation i only have problems when idle.

I think I've already figured this out, but thank you for all your suggestions. Will keep monitoring for a few more days and declare this case closed (pun intended).

Yup. I believe when set to "Auto" it defaults to "Low Current Idle", effectively bringing down the minimum CPU voltage to 0.4v. I've changed it to "Typical Current Idle" and now it never goes below 0.8.

Not sure if this would fix crashing, but it definitely helped my system to survive long periods of idle without freezing...to death. It's been a whole day now and it still runs.

Latest as of now - 3B7QCXE7

Stability.... Finally.

My config AMD ryzen 1700x
ASrock X370 Gaming X
Radeon RX560 (MSI)
RR622 Esata Raid card.
32 GB Adata Spectrix 2666 memory
2xHGST 2.5 drives in Mirrored config.
Bios (Latest)

SO what worked for me and your mileage my vary on this.

Initally I had to have OC my chip disable cool and quiet and disable the system C sstates, as well as set the PCIE slots from auto to GEN1.

This gave me quasi stability would stay up 2 to 3 days before locking up.

I had replace the PROC, the Video, the PSU and memory pretty much everything. save for the System Board, and had requested a replacement from ASROCK (but they were ignoring me at this point.) so I started looking into other vendors system boards when I noticed that pretty much all other vendors boards only have 5 PCI-E slots. and thought could this be some kind of timing issue so I moved the RR622 from the bottom PCI-E slot to the one above the the 1st x16 slot.

Boom Stability... for over a week now up 24x7.  Running at Bios defaults only changes were to change the drives from AHCI to Raid, and set the fan profiles to performance.

when I'm not there it runs the BONIC platfom to contribute to medical research so it's pretty much stressed 24x7

So it looks like there is some kind of timing issues in slot 6 for PCIE devices. SO my suggestion is to move any add in cards up as close to slot 1 as you can.

Additionally I also find the system is more stable with a Radeon card as opposed to Nvidia so either AMD did something hinky to make their cards more attractive or Nvidia is having some kind of issue or ASrock has some timing issue that is evidenced in Nvidia moreso than with a radeon.

Go figure.
