B450-VDH w/2400g Unstable
« on: 18-December-18, 13:51:55 »

I have:

B450-VDH
AMD 2400G
G.SKILL Fortis DDR-2400 (F4-2400C15D-16GFT) 
Patriot Scortch M.2 240GB


I had the hardest time to get it to boot, it would just hang at CPU.    I have 2 monitors, 1-HDMI and 1-VGA.    I had to disconnect the HDMI monitor to get it to boot randomly.   I flashed it to M20 firmware (November 2018).    It got better.    Was able to boot most of the time.   Onto installing Linux.

I got Mint installed, had to manually install 4.18 kernel to get any sort of graphics support.     So far, great.    Stable, running BOINC/World Community Grid computing for 24 hours straight, went back to O/C RAM to 2666 (baby steps) and still rock solid.  Until....

If I plug into HDMI or DVI for second monitor the machine locks up hard --- pull power plug.


Thoughts?

I did figure out that Virtualization was not turned on in the BIOS.

I turned that on and the system is a heck of alot more stable.

I am running 2 monitors now VGA and HDMI.

I am running Mint Linux with kernel 4.19.10 (thank you to UUKU app)

I'm still getting some lockups and have to remove powercord to reset the unit....but it's a whole lot better.

A continuation of this thread...

I'm now using BIOS: [font=DINPro-Regular, Arial, Verdana, Geneva, 微軟正黑體, sans-serif, sans-serif]7A38vM3[/font][/color]

I am using Linux Kernel 4.20.6
I'm using the Mesa Drivers from GIT
I'm using the AMDGPU firmware from GIT

I am still having lockups and instability.

I can only think that since updating all the Linux drivers and code has done nothing that there has to be something with the BIOS.

Can anyone point me in the correct direction for BIOS settings?    How about Beta BIOS from MSI?

Check default ProcODT by Ryzen Timing Checker.
And set one step higher than default ProcODT Value.

For two single rank RAM, ProcODT is 60 or 68.6

I ran a Linux tool and here is what I found:

Try 60 ohm for ProcODT.
Check with warm reboot After set values and get black screen on warm boot, try one step lower ProcODT Value and cold boot.

I tested 60 and the machine became extremely unstable.    It spontaneously rebooted within 20 seconds of just being booted and logged in.    I tried another boot cycle and it crashed upon trying to boot...

I tried 68 and it seemed to be alright there.  


I put it back to auto for the time being......

I just flashed 7A38vM4 and what a nightmare.

Flashed from USB key as usual and at the end everything just went blank....monitors keyboard and power light on case....but power was still on, fans and HDs still spinning....

I waited another 5 minutes and nothing.    So pressing power button did nothing....great....pull power.....

Press power button and things spin and no lights anywhere....do this 4 or 5 times...

Finally pull battery, put jumper on for 5 minutes...nothing.....do it again for another 5 minutes....nothing

Finally pull battery put jumper and pull drives from SATA connections......and that does it....booting in BIOS safe mode.....I can get into the BIOS, and set all my settings. 

F10 to save my settings and reboot......

Power light is on and nobody home...no monitor, nothing...grrrrr

press power button does nothing....pull power

press power button....things turn on and spin but no lights and monitors.......this is getting old

pull power, wait.......press power button......


everything fires up!     I boot into Linux!  Woo hoo.....fsck required for all disks!    eeek 10TB of disks.....ok sit and wait for 5 minutes....

fsck is complete!    Woooo Hooo!      I am back.....

Sooooo I thought M4 BIOS would fix my problems.....I was wrong.......

Any suggestions?    I'm getting ready to swap parts.....   I've been building PCs for 20 years....I NEVER had any of these issues........

...but the thing is, is that once the machine is in Linux and running, it is quite stable.   Not 100% but it's come a long way.

I figured out that if I have any of my VirtualBox consoles up, that eventually the whole machine will become non-responsive and eventually halt.

I can transcode video for hours on end and it will be solid.

But warm reboots are about 25% successful and hard power ons are 50-60% successful.

Any thoughts on power supply issues maybe?   If so, you'd think I wouldn't stay up and running either....

Any thoughts on different RAM?

Any thoughts on different motherboard?

If warm boot fails, it need to set ProcODT one step higher or lower values.
I also have unstable RAM problem after changing power supply.

Some of voltage parameter need to be change but I don't know.
I think setting ProcODT is simple and fast.

If ProcODT don't work, try change CLDO VDDP setting.
Default CLDO VDDP value maybe 700. But I don't know about this value.

So on my board I can't find CLDO_VDDP only CPU VDDP.     Is this the same thing?

No, It's different.

Another way is change RAM primary timing. try 14-15-15-15-40(Tcl - 1 and Tras + 1).

In my case, unstable status appears after 80+ CWT oem power supply,
and I stablize by making even Tcl and one step higher ProcODT.

I left ProdODT on AUTO.\

I set the RAM timing as you recommended... Tcl -1 and Tras +1

Warm boot might be better....cold is still hit or miss.

Any thoughts on further tweaks?

Try ProcODT 48/53.3(may default)/60/68.6 and set VCore voltage 'Auto' to 'Offset Mode'. I guess ProcODT is better works on VCore Offset mode.

No VCore "offset mode" on this MSI board.

I've tried ProcODT at 68.6, 60, 53.3 and cold starts are horrible.

I'm testing 48 right now but it's looking to be the same.

I updated to the latest BIOS last week.   No change in stability.
