Rockpro64 RAM issues
#1
Hi All,

What methods are you using to test memory? I have clear Debian install(not depends what distribution is used) and when the bigger size of memory is allocated with memtester and shows multiple failures.

The same not depending from power source 12v3A and 12v5A was tested:

Code:

Why I am testing is that Debian crashes during regular operations. Rsync is not usable including any other higher load tasks which finishes with random backtraces.

I don't own RockPro64 but there's something about memory glitches in the wiki, does that match your symptoms?

Please install meemtester and check out memory stability.
sudo apt-get install memtester
sudo memtester xxxxM

For 2GB Board xxxx = 1700
For 4GB Voaes xxxx = 3700

I am having the same issues:

Support at Pine is unfortunately terrible, and I had to open up a paypal dispute.
