RAM upgrade for Synology DS1815+
My NAS been 6yrs now. I feel it slow down quite sometime. Like
1) The media player respond slow to the NAS file. Got to wait abit each directory.
2) Torrent file process slow if too many in 1 time.
3) Slow in photo/video upload in photo station
4) Photo station or Server log in slow.
Start to suspect that the RAM is not enough. NAS original comes with 2gb Ram. Follow the NAS spec, its max can upgrade is 6gb. Mean I can upgrade another 4gb Ram. There is 2 slot on the motherboard.
So brought a 4gb DDR3L 1600mhz Sodimm Ram. Install and try to boot up.


It doesn't want to boot up. The button light flashing nonstop and nothing happen.
Thought the Ram is bad. Or not match? But I brought 1pcs only. Can't test to prove.
Then I remember I did upgrade my PC Ram last time and got spare 2pcs of 4gb = 8gb Ram. But the model is slightly different.

I give it a try. But this time I take out the NAS 2gb original Ram and replace both together with 2x4gb Ram. That is 8gb which is over the NAS spec max 6gb.


Then boot it up and it run! No error.

I thought WTH synology bullshit with the 6gb max Ram.
Log in to server and check any error. Nothing. Cache increase in memory and everything run fine.

Speed and response increase so much now. No lagging.
Wonder can I install 8gb x2 =16gb ram.
