Hi.
Since audirevana didn’t detect my system memory, I couldn’t configure the preloaded memory. How do I solve this?This seems to be causing problems when I play upsampling music.
Thanks!
here is the debug info

Welcome @LichungLiu,
What an odd problem. It seems there is something wrong with your Windows installation.
Just to double check:
How much memory does Windows itself report? (Look in Windows task manager/performance/memory).
Do you have problems with other programs not recognizing RAM in Windows too?
This is the first time I see a problem like this. Sorry but I don’t know what to think of it.
I will signal @Antoine (official support) here. Maybe he can shine a light on it. He will probably react during working hours (monday - Friday). You can also send a mail to [email protected]
Here is the problem that @AndyLubke is addressing from your debug information report, note the bold text below:
Maybe you need to reinstall Audirvāna?
Thank you for your concern.
I’ve reinstalled windows11 and audirvana but still the same result.
It works fine when I use another computer, but on this one I modified the fanless case and power supply in order to run Audirvana.
The thing is:
Why Audirvana thinks you have a windows 11 system with 0gb of memory?? that is why it put the lowest memory buffer size… 256mb and can’t be moving forward.
First, no one can have a zero memory on a computer…
Did you buy that memory stick elsewhere…
have you tried to remove your memory from the computer
and add them back again to see?
Then again, why it is only Audirvana buggy with that when all other softwares are good with it??
Monday work day coming soon 
wait for @Antoine to see
It is highly doubtful that the Audirvāna team will be able to help you when the platform has been modified… You will need to prove that it can run another audiophile digital-audio application, especially since you already know that Audirvāna is operational on another computer… What do you think the Audirvāna team can help you with…? This is a bizarre case and if AndyLubke has never seen this behavior, it is a gross anomaly which points to some form of damage to the computer platform or memory bus or the physical memory.
My intel nuc modification only has a fanless case and uses a linear power supply, without modifying the computer platform or memory bus or the physical memory.
The strange thing is that I originally plugged in two 16GB memories, but the pre-loaded memory can be adjusted by plugging in only one 16GB stick.
I currently have a 16gb stick plugged in, and I would be very grateful if this weird problem could be solved.
Thanks!
So with one of the 16 GB RAM sticks plugged in Audirvana works, recognizes the memory and you can adjust the preload buffer in Audirvana?
I think you discovered the problem yourself. This is not something Audirvana can fix. There seems to be some sort of hardware problem. Did you try another (new) RAM stick instead of the faulty one? Did you try to place the RAM sticks in different slots or switch them? If you use your NUC only for music 16GB RAM is more than plenty. Maybe you can live with that?
It is always wise in these cases to do a thorough diagnosis of the RAM in your computer by using the memory diagnostic tool in windows:
How to Use Windows Memory Diagnostic
Again: The root cause of the problem is in your hardware/computer configuration and the fix must be found there. This problem IMO can not be solved in Audirvana.

The fact is, that you handled the computer system platform by modifying the fanless enclosure and changed the power-supply… These variables along with potentially defective RAM card or other RAM pairing disparagement, or potential slot damage, and the fact that Audirvāna system operations are normal when you have a single 16GB RAM card installed puts the responsibility on you to solve…
You are better served by seeking advice from the hardware platform manufacturer, Intel and Microsoft… Maybe the Audirvāna community can provide insights, however you must temper your expectations… It appears you have identified the source of the problem yourself… The majority of help and insights you will receive from the Audirvāna community forum will be in the software configuration and the synergistic relationship with your DAC and network synergies.
Hi @LichungLiu ,
Some additional information. I also have a modified NUC (put it into a fanless case and replaced the external switching psu brick with a linear one). In my case everything works well with Audirvana.
Audirvana sees my 32 GB RAM perfectly and I can adjust the preload buffer in Audirvana.
Specifics:
- NUC i58BEH
- 32 GB RAM (2 sticks of 16 GB RAM)
- 500 TB internal SSD
- AKASA Turin fanless case
- OS: Windows 11 pro
- Installed: Audirvana Studio, Audirvana Origin, Foobar2000
- Audiophonics Linear external power supply (LPSU100 19V 5.25A 100W)
- External DACS (via USB): Topping DX9, Holo Audio Cyan2 (both played via ASIO)
- Local Music library is on a external USB SSD and on my NAS
This strengthens my opinion that there must be something wrong with your configuration/hardware. The fix of that problem lies outside Audirvana.
I understand this does not give a solution for your problem, but at least I hope it points to some logical direction where to search.
Could this be a issue with mismatched ram modules? Or is there a setting in the BIOS or windoz itself to enable/disaable the support of multiple simms/dimms/sticks?
I remember messing with BIOS for memory setup when I built my ASUS watercooled, de-lid, overclocked i8700K windoz 10 now 11 years ago… 
Hi @LichungLiu,
Wehn you are on the audio settings page, what do you see under the Computer section under Windows 11 (26100)?
Does it display the correct amount of RAM your computer can use?
I agree that this issue involves a wide range of aspects, so I have also considered the bios settings and hardware.
Maybe I’ll check my existing memory with Windows Memory Diagnostic. Thanks!
I am using memory from the well-known manufacturer Kingston, but I suspect it is a memory compatibility or pairing issue.
I have purchased two Micron 16gb memories and will compare and test them after receiving them.
Thanks!

Hi.
If I plug in a 16gb memory, audirvana will display 16gb normally.
If I insert two 16gb sticks, it will become 0.
