X370 Taichi SATA SSD goes missing

I put the old 1800x in the new msi xpower and the sata's are woring, 534 read 493 write. I'm guessing the taichi is faulty and i should rma? LE: another thing i noticed is the fans on the cpu cooler (ek predator 360) are a lot more quieter than on the taichi No other way to test it, unless you wait a while to see if the SSDs disappears again on the new board. Given the way the Ryzen platform is designed, it seems the Taichi is the problem. So either RMA or return to retailer. The fans are quieter on the other board no doubt because of the differences in the fan profiles between the two boards. Were you using the default profiles on each board, or a custom profile? Plus there are multiple built in profiles on both boards. There is no reason why they would be the same on both boards. There are no standards regarding fan speeds at specific PWM levels (4 pin fans) or voltage (3 pin fans). Also, every fan model is different in its specs, there are no standards for starting voltage, minimum and maximum RPM, etc. Were you monitoring the fan speeds on your EK 360 on the Taichi and MSI boards? If they are quieter with the MSI board, they must be spinning at a lower speed/RPM. There is no other possible explanation. Yep, the fan profiles are probably different. On the msi board they are inaudible, on the asrock they blasted almost full force :P Don't know why the stock setting would be full blast tough. I didn't change anything from the stock bios config.

Two possible reasons for using the Full On setting as the default.

The main thing is ASRock has no idea what CPU cooler is being used. Sure, you use liquid cooling, but most people don't. The full on profile is the default to protect people that use cheap CPU coolers or those trying to adapt semi-compatible coolers to AM4 mounting. Then ASRock hears from users that say, "Why did you let my CPU over heat!". That has happened.

The other reason is to inspire you to learn about the fan profiles.

Better description than mine with my poor english The BX100 is still disapearing sometimes when I soft-reset the system. Since it is on SATA3_4 while SATA3_3 has an normal HDD connected it is working fine when the system is runnig and it is BIOS-found. Not usind SATA3_3 and BX100@SATA3_4 it is still disapearing every soft-reset. This has to be some crazy energy-saving stuff or powerdelivery detection problem ... The Taichi BIOS is a bitch

From my post on page 1:

I'm not sure if your board's UEFI has these options, or what version you are using, I hope the latest 2.00 version. In the Advanced screen, do you see the AMD CBS screen?

If so, in that screen find the Promontory Common Options screen, and in there the PT SATA Configuration screen.

Two options in this screen, PT Aggressive SATA Device Sleep Port0 and Port1. Set both to Disabled.

In the AMD CBS screen, there is also the FCH Common Options screen. The FCH is the X370 chipset, which can support up to eight SATA III ports. It also has a SATA Configuration screen. Why there are both Promontory and FCH SATA screen options, I am not yet clear about. Both Promontory and FCH are terms for the X370 chipset.

Regardless, this SATA Configuration screen has Aggressive SATA Device Sleep options, again try disabling them.

I can't guarantee disabling these options will fix your problem.

My MX100 on SATA port 2 has never disappeared, through multiple restarts, a UEFI update, shutdowns, and a long Windows Sleep over a 24 hour period. I'm using a X370 Killer SLI/ac board.

I'm NOT saying you X370 Taichi users should not be having problems. Impossible for me to know what is going on with your boards. If this was isolated to the MX100 SSD, I should be having the same issue. That SSD is not empty, and I've accessed files on it multiple times to be sure it is working.

SSD speeds are Ok, although the 4K speeds are lower than I normally see on my Intel systems.

How are your speeds to either drive?
