Ryzen 2400G new build problems

[xStampede]

Hi,

specs:
CPU: ryzen 2400g
motherboard: MSI B450M PRO M.2
ram: Corsair Vengeance Value Select 8GB 2666 CL18 (on motherboard compatibility list)
SSD: M.2 WD Blue 3d NAND 500GB
PSU: LC power LC300STX

PC CASE: Inter-Tech IT 607 Desktop http://

I'm experienced builder but it's my first time with AMD, had no problems with my 7 intel builds in the past.

i just build a brand new ryzen 2400g and i have many problems, first of all it have micro stutters, even when playing YouTube video in lower resolutions. It finishes Cinebench with a little bellow standard score of 750 average. I read a lot about this problem which seems quite common but noone of the solutions i found worked so far, i tried setting CPU multiplier to 36 cause on auto it ran at 3700 MHz according to CPU-Z which is higher than it's base clock.

updated BIOS but didn't solve the problem, there is a newer beta version that i still haven't tried.

I tried turning off Turbo boost and C-stages, at some points it worked for a while but then problems again

Motherboard has 8pin CPU connector but power supply has only 4pin one, so 4pin's are empty.

tried setting lower GPU clock and CPU clock but it didn't help, tried all different drivers,

now i'm even getting blue screens and windows 10 doesn't work correctly. At this point im out of ideas. I have no idea which part is defective and what is causing the problems. I hope anyone here have any idea on what to do next.

I will test ram first, memtest86.com should tell
reset CMOS battery first
What BSOD error is it?

1 stick or 2 stick so it can run dual channel?

1x 8gb stick

replace it with 2. early this week another user having the same issue.

I have put the ram stick in the second slot, the one further away from CPU, now it works fine but it probably won't last.

Also the PC was turned off for a while, it might have cooled down, im suspecting that motherboard with no VRM heatsink and no back fan might be causing it to overheat and cause microstutters.

The stuttering returned of around 10 minutes of playing YouTube video in 1080p. Trying memtest64 now, for how long should i run it?

I forgot to write the BSOD error down, will do it next time it happens. Will try removing CMOS later after memtest.

reset CMOS before memtest86.com is my suggestion
not 64
a couple of hours is recommended.

Where can i find the jumper cap?Should it be in the motherboard box?

Others say 7 passes through the tests is enough to clear the ram as good (though obviously one fail is enough to show it's bad).

JBAT1 is right below the battery.

JBAT1 is right below the battery.

I found JBAT1 but there is no jumper cap, and there are 4 pins while instructions show only 2 pins. Where can i get a jumper cap to put on?

 

[vapour]

In that case, just take out the battery, touch some metal before doing so. Wait for 1 minute and put back.

I have reset CMOS, same problem, in YouTube there are microstutters which are heard but hardly seen. Sometimes it works fine for 15 minutes if i turn off turbo and c-state.

sounds like a RMA MB to me.

Should i RMA the CPU too? Cause i bought it from another country (Germany).

 

[vapour]

cpu is much less likely to be the issue.
Do you still see Blue Screen? I would like to see the error before RMA. Are you sure all the drivers have been updated?

 

[xStampede]

Yea, i installed all the latest drivers from motherboard website, also installed latest the Ryzen 2400G drivers from AMD website, updated bios to newest non-beta version, tried all suggested solutions i found on google, nothing works for me. The best i get is 15 minutes of working before stuttering starts, and when it starts it doesn't go away until restart.


Also on front 3.5 jack for headphones, only leftside work, right side is mute, while on the back I/O 3.5 jack headhones work just fine.

Also VLC gives just green screen while windows default player doesn't put out side, just video works.

So should i RMA the motherboard?

 

[xStampede]

I think the BSOD was caused by my tinkering with settings, it doesn't BSOD anymore.

 

[vapour]

although highly unlikely, try to borrow a psu to test first. That LC Power is poor quality.

This is not my main rig, i will try with PSU from main rig tommorow, its EVGA G2 750 supernova, high tier superflower.

 

[vapour]

yep, let's rule out all other possibilities first.

 

[xStampede]

I tried to swap RAM, couldn't try PSU cause on my main rig the 4 pin CPU power goes behind the motherboard and it would be a pain in the ass tinkering with my perfectly working PC just to try it.

I decided to RMA the motherboard, after i lift up the stock AMD cooler i noticed there was a very small amount of non conductive thermal paste(factory applied) on the side of CPU, could have that been the cause of the problem? Or should i go on and RMA the motherboard?

Also when i was cleaning the paste from side of CPU a small amount went under the metal cover of CPU(or whatever it is called, the part you remove when deliding), could that make anything go wrong?

Hey, i RMA'd the motherboard, now after i month i recieved it back, on the return paper they wrote "no error found" and returned the exact same motherboard. I wrote a comprehensive error description, the company i ordered from is from another country Germany and is kinda big and busy so it's almost imposible to get in contact with RMA team, i don't know what to do at this point.

Considering that audio was working only if connected from back panel, can it be CPU fault or is faulty motherboard for sure?
