[SOLVED] Help me solve a mystery ?

[Naks92]

Hi, this is my first post here. despite following this site for 10 years. I have never ran into an issue like this before. And I guess it's time to ask for help.
I recently upgraded to the new Ryzen 3600 processor. And everything's been going pretty smooth until today.
So today my PC started to act up.
I sometimes get random restarts (black screen, then bios post) and when I'm playing CS GO online, I get a BSOD with the error message : "kernel auto boost lock acquisition with raised IRQL"
I read somewhere that this could be related to the Wifi Adapter, so I turned it off and decided to play offline. In this situation, the game just crashes to desktop. I'll post my config and I'm hoping maybe some of you have come across this issue before. I've tryied many things like changing my RAM speed and timings (Issues were still persistent when all BIOS settings were on default.
Looking at my logs I noticed an error related to "nvd3dum.dll"

Config :
CPU : Ryzen 3600 (No OC)
Motherboard: ROG STRIX B450-F GAMING
GPU: MSI GTX 1050 Ti
RAM: 8Go TeamGroup VulcanZ 2666 (1 Stick - Single channel)
PSU: OCZ ZS Series 550W
Wifi Adapter: Asus PCE-AC68
CPU Cooler: CoolerMaster H410
SSD: Crucial 256Gb

I thought that the problem was related to my ram. But when I put it at D.O.C.P. my system becomes more unstable.
I ran memory diagnostics and it said that it was OK.

Thanks for reading. Any help would be much appreciated. Let me know what other information I can post to help solve this.

it could just be a random fluctuation would reduce the voltage enough when under load, if set to auto, to cause the errors you sometimes got. Since it wasn't a constant thing and only happens in game.

So, gaming is impossible now. Getting crashes way more often (Crash on start-up or max 2mins in-game). Should I up the voltage a little more ?

 

[Colif]

did you run Prime95 again after voltage change to see if it fixed errors?

could be the increase didn't fix it. I don't know if @PC Tailor is around, he might know more about this side,
You might want to set it back to auto until he appears

Prime95 runs pretty stable after manual voltage setting. no more failing workers. but in-game is worse after setting voltage to 1.4v.

After settting voltage to 1.425v gaming seems more stable. Will need to test for more time to know for sure. But from what I've been noticing with every change, it seems that these problems are related or at least affected by CPU voltage. I also updated the Bios firmware since a new one came out but no changes.

 

[PC Tailor]

The 3rd gen Ryzen can quite naturally run up to 1.5V usually between 1.3 and 1.5V
Mine actually runs at 1.45 pretty constantly with no BIOS manipulation.

It has a boost from idle feature whereby it applies heavy voltage to each core to boost it out of sleep and then stabilise which results in voltage and heat spikes when this happens. In effect, it boosts a core out of sleep, so you have a big amount of voltage rush into a small space, thus the big and seemingly random heat and voltage jumps.

In doing this it also boosts it to high speed, then decreases and stabilises or stays at boost speed. So I'd be monitoring how the CPU is performing in Ryzen Master or HWInfo for example. Do you have power settings enabled to Ryzen High Performance mode?

Hi, sorry for the late reply. I was on holiday for a few weeks. here's the latest update I have:
System is always unstable and Prime95 always gives me the same rounding errors on workers 3 & 4
Here's what I've tried so far :

- Disabling LLC didn't do anything.
-Disabling LCC with a negative offset of 0.1v : system posts but freezes after a few seconds in the BIOS.
-Setting the voltage to manual : 1,431v : better stability, but still results in some instability (BSODs and crashes)
-Setting voltage to 1.44v: Even better stability but upon checking HWinfo, my Vcore spikes to 1.497v and system is too hot on idle.

It seems absurd to me that I need to put the Vcore that high for stability. I am considering RMA the card but I'd like to run a final test by trying different ram. My friend is on his way with his DDR4 kit and hopefully I'll hafve some answers. I recently came across a couple more posts on the internet of people having the same exact issue.

If you go to this link and scroll down to the bottom, there is a post by a guy called Seba who had the same issue.

This one is from this forum but the thread hasn't had any new responses.

i have asked about this on another thread, some one might reply.

I am not sure if PC is around this week.

 

[Naks92]

so my friend brought his kit of ddr4 ram and I’m seeing no change in my system. I have returned the cpu and motherboard to the shop I got them from. Should take about a week to get a new cpu. Also gave the motherboard just in case. They’ll return it to me if it’s fine. Will keep you posted. I really think that there is a hardware issue, either with the CPU or the Mobo, but my money’s on the CPU.

I think the steps you've taken are appropriate.
Let us know what happens, apologies for not being around!

Hi guys ! So today I finally recieved my new 3600 after almost a month of a painful RMA process, but I got it. And it runs perfectly. No rounding errors, no BSODs, tested everything out. I guess I had very bad luck and got a dud CPU. I hope this thread can help solve this issue for people who may have the same problems. Thank you all for your patience with me !
