Timetec DDR4-2666 16GB Replacement for Synology D4ECSO-2666-16G DDR4 ECC Unbuffered SODIMM 2666MHz CL19 Dual Rank
I tested the Timetec ECC RAM that claims to defeat the Synology RAM Vendor Lock in the same manner as the Arch branded memory listed elsewhere. This RAM is available in the US but can be purchased through Amazon EU and Amazon UK for a very reasonable price - £110 or so and the £5.21 delivery charge was discounted at checkout.
Amazon UK listing:
Timetec DDR4 2666MT/s 16GB ECC SODIMM - Amazon UK
Installed and tested over the last 10 days, alongside a Synology SODIMM that is not listed as compatible either.
As the Synology Vendor Lock Memory Test looks for specific named manufacturing brands the Timetec memory passes the check in a similar way to the original Synology memory, by listing just 4 digits of hex under the 'Manufacturer' tag.
As the SynoMemCheck only runs a boot and may be skipped entirely due to the boot sequence it can take a while for the check to actually spot 'unsupported' but otherwise ok RAM and actually log and notify it. The check can be run manually though via the command line:
There have been no mem_check failures logged under DSM6 or, more recently, under DSM7 and the RAM works perfectly and passes all tests.
Looks like a winner so far and I am now rocking the full 32GB of RAM in my RS1221+.
