Nucleus Memory Upgrade

Memory is dirt cheap now.

Adding it for future concerns is a reasonable action.

Can’t you ssh into a Nucleus and check for installed memory and use via top?

Perhaps the Nucleus memory spec should be increased, but I’m pretty sure it’s sold as an appliance, and not as something to be tinkered with.

Adding RAM status to the web admin page would be really useful, but it would probably lead to reports of 64Gb RAM sounds better the 32Gb, or some such! I’d also want reassurance from Roon that this extra RAM is actually utilized, otherwise, why do they set the spec so low?

I run a Nucleus, with over 8k albums, and around 115k tracks.
It works perfectly. Surely if Roon thought that it needed more RAM to run ROCK, they would have sold it with more?

Not technical enough to do this lol

I think you can safely assume that if the system boots with the new memory installed then it is using that memory.

Performance far more likely to be determined by the speed of the database and DSP ie the processor and the system storage (the SSD card). It won’t be determined, significantly, by RAM size or the speed of the disk holding the music files. I assume that Roon Labs have designed the system software to function with the given RAM, so I am not sure you would see any performance improvement.

That is a big part of the problem I think. When I built my MOCK I had something of an internal struggle limiting myself to a pair of 4gb sticks.

I felt the processing time is faster after adding 8G, boot faster and as well as loading music. Not hearing any SQ different yet

Then it probably is using the ram. That’s useful to know. Enjoy the music :slight_smile:

How do you know when ROCK is running out of system resources? Both CPU and/or RAM?
I have nearly 6.5K albums, so 85K tracks on NUC5i3 with 8GB RAM - this could go to 16GB, but would it make a difference?

Good find!

Yes - excellent hunting!

I remembered coming across it when helping someone with a 300k library on nucleus. (Search Danny Nucleus Memory)

Good find, but still no way to verify after adding the RAM into Nucleus.

I don’t think it would go through POST if it wasn’t being used. Just guessing though!

So, now you have two memory slots, one with a 4gb stick and one with an 8gb stick?

Although there’s no hard and fast rule against mixing different size memory sticks, another 4gb stick would’ve been sufficient.

Unless you’re a gamer or want to run multiple VMs, 8gb is enough for most things, especially with the Linux fork that the Nucleus uses.

Why would you??

A symptom of needing RAM is a crash, nothing else. Roon OS does not have a swap file or do anything else memory based on the SSD. It’s all in RAM.

If you added RAM, you shouldn’t feel any changes other than “its not crashing anymore”.

If you weren’t crashing before, adding RAM will not cause your system to speed up (Nucleus doesn’t swap), and should have zero other impact other than growth potential. Roon doesn’t use more RAM just because it has access to it.
