Please add yet another compatible DRAM module to the Wiki

Unread post by udif » Mon Dec 02, 2019 4:07 am

Can you please add this working DRAM configuration to the Wiki?

TEAMGROUP Elite DDR4 16GB Single 2400MHz (PC4-19200) CL16 Unbuffered Non-ECC 1.2V SODIMM 260-Pin Laptop Notebook PC Computer Memory Module Ram Upgrade - TED416G2400C16-S01
https://www.amazon.com/gp/product/B01HOM9WCI/

I used 2x16GB to get 32GB.

For some reason at first it didn't recognize the 32GB configuration (I usually turned off the board after 5-10 seconds of failing to boot), but at one point I turned it on and went away, and when I came back, it was working.
Once it worked, further boot attempts were quick, even when I powered it down, disconnected the power and then rebooted the H2.
Does this make any sense? (long initial boot, quick boot afterwards)? Or is it some other quirky thing in my setup (perhaps the contacts are not 100% ?)

Thank you for the report. I've updated the WiKi page.

It is very normal.
The first boot needs a long post process to start the BIOS due to checking the RAM timing parameters.
Once the configuration is stored into the backup memory in the SoC, it boots quickly.
If you disconnect the backup coin battery for a while, you will meet the very slow booting process again.

Maybe you should add a note about this in the Wiki as well.
I didn't expect the long wait, and added/removed/swapped modules several times to rule out a bad module or a bad socket.
