Hi,

 

I have a build based on a Core i7, the first CPU was a 13700K but it got replaced with a 14700K after it fell victim to the intel bug, but I'm still having problems, including crashes and kernel errors (and yes, I have the latest BIOS). It could now be a new fault related to the BIOS/CPU, or a MB, RAM, or HBA problem. I have no spare hardware so it is hard work trying to get it stable. 

 

At this point I'm getting really tired of fighting with it so I want out. I'll re-purpose the hardware for a PC running windows, if it gives me grief it can go back to store under warranty (they only understand windows). 

 

The question is - where do I go for my Unraid build? I run Plex and Jellyfin, the arr suite, two instances of Frigate (with external TPUs), and a bunch of other stuff....

 

The way I see it I have three options:

• Buy another system more or less the same (e.g. Core i7 again, different MB, 4x16GB RAM to make it easier to diagnose future problems etc). Pros - cost effective, easy to do. Cons - May well get the same problems again. 
• Buy a new system based on the Core Ultra range with a Z890 chipset MB. Pros - no more voltage problems, power efficiency. Cons - Need to run Unraid 7 Beta, no support for iGPU transcoding so will need to buy an Intel Arc, possibly swapping one set of problems for another, pay a premium for bleeding edge, not a lot of community support. 
• Change to AMD. Haven't run AMD for 20+ years as had bad experience in the Athlon days. Pros - probably cheaper, no intel crap. Cons - will need a solution for HW decoding (up to 5 parallel streams) so either a recommended graphics card or an ARC (I assume they work with AMD), and then Unraid 7.

 

Thoughts? What would you do in my position? And if you pick an option, any recommended specs...especially if I need a graphics card for transcoding....I've not bought one for years. I can take any size MB....so there is no form factor limitation....

 

Any help gratefully accepted.

Have you runn a memtest yet?

 

I ran memtest a bunch of times a month or so back when the CPU decided to die. Everything passed....it is possible that now the RAM is having a problem, but I've also read in places that the Intel fix for the over voltage issue can also create problems. Some of the errors imply the MB has a problem, but as always it can be anything...which makes it so hard to diagnose when you don't have a stack of swappable parts. 

 

I posted here about the current problems I'm having....

 

The issues are intermittant....but they always show up....

@ChirpyTurnipyou are not alone...

i have a i7-14700K too was crashing daily multiple times a day every now and then id get a few days.

Whent he bios updates came out it was okay but i would still find the system had crashed a couple times a week..

But now for some reason in the last few days ive been getting all kinds of segfaults. random containers crashing and rebooting.

Ive even have had my jellyfin db just get corrupted.

I have tried swapping around my ram and im still seeing segaults, no matter which sticks im using.

im down to two things also, my MB or the cpu.

Ive even tried stressing the hell out of the system with like https://github.com/Mysticial/y-cruncher
 

ran 100% cpu cores running 100c using 90gb of ram for 30 minutes, while maintaining all my services and it was fine.....

i have no idea what is causing this and it is driving me insaneeeeeee

Yup. Check out my tale of woe here: Kernel Bug Error

 

Nothing has improved for me - but I've pretty much eliminated everything except CPU (previously replaced) and the MB. 

 

I now have a new AMD machine (sadly only running a 7600X - so less than half the compute power of the i7, and no GPU transcoding) but this machine can now do all my Frigate work + Arr apps. The CCTV storage is local, but the Arr apps write back to the main Unraid machine via NFS shares. 

 

In the new year I plan to convert the failing Unraid server into a WIndows machine (new desktop PC) and then I will build a Core Ultra-based machine as my new main Unraid platform. According to Lime Tech there should be support for Arc GPUs from v7.1, this should be a small hop from 7.0 once that is released so hopefully early next year.

 

If the flakey Unraid machine stays up with with just storage + Plex as loads I will keep it running until 7.1 is available, if it stays really bad then I will move early and the bandwidth impaired will get minimal transcoding. 

 

So we will see....personallly I'm leaning towards this being another CPU problem....but it might work fine under WIndows....so we shall see! 

 

In the meantime I think I will soon upgrade both Unraid systems as I hear there is a nasty NFS bug - I've not come across this yet, but after a nightmare run of late I don't really need to stumble into another cesspit of despair!
