528x ram/memory upgrades
I am looking to upgrade the ram in my 528x, currently with the stock 4g. Has anyone upgraded theirs yet? Is there a list of compatible ram or details/specifics somewhere? also considering upgrade ...
The 600 series can use a higher speed RAM than the 500 series
RN526X/RN528X: 4 memory slots (Max: 64GB), support up to DDR4-1866
RN626X/RN628X: 4 memory slots (Max: 64GB), support up to DDR4-2133We don’t support upgrading the RAM. You do so at your own risk. Be sure to run the memory test after replacing the RAM.
Very strange, I spent a few minutes googling and keep seeing something like this example:
https://www.newegg.com/Product/Product.aspx?Item=N82E16820326400
This shows both ddr4 *and* ddr3 ?!?!
16GB 288-Pin DDR4 SDRAM ECC Registered DDR3 1866 (PC3 14900)
I can't seem to find anything that has ddr4-1866 / PC4-14900
for other's future reference, I found some additional info on my specific device:

I googled the part # TS512MLH72V1H and got https://us.transcend-info.com/Embedded/Products/No-688
which handily shows the specs and part #'s for other sizes too
Now, trying to find those in stock somewhere for a reasonable price..
For future reference for anyone looking to upgrade their 528/628:
I ended buying this ram and it past a couple memory tests and I have been running it for a bout a week now with no apparent issues.

I only bought 1 stick so far. Been monitoring with htop and while it has always pushed close to 4gig ram usage, I haven't seen it meet or exceed yet, rest is used for system cache.
And while I am still bottlenecked by cpu at times, the overall system has been much smoother and more responsive.
Anyway, so far so good on the ram upgrade.
Just to add - for anyone else searching the forum.......
I used these for a 628x:
Samsung M393A2G40DB0-CPB0Q
4 x 16GB to give the full 64 GB supported (memory repurposed from a decom'd server)
Specs here from Samsung:
Memory test passed and no issues to date.
