No kind of, but not that generic ... the NAS does (for example) require 1.35V DDR3L, requires single channel resp. can't work with dual-channel-SO-DIMMs,, Compare the notebook memory you have in mind with the commonly known working Crucial or Kingston modules.
Thanks schumaku,
I'll keep that in mind when looking for SODIMM replacement.
I have just bought a Qnap TS-253A-4G my first NAS and would like to now about this Crucial DDR3L-1600 SODIMM SC - 8GB RAM is okey for this model. What is maximum RAM 2X4GB or 2X8GB in the spec stands 8GB but is it per block or is it toalt 8GB. I can see 2X8GB works with a TS-451.
Ok sorry this is the first time I use this. I had written this when I came to think it was better to write it in my own thread. It will not happen again.
Are you guys noticing a large performance increase from 2x4gb(8gb) vs 2x8gb(16gb)? I'm planning on running virtualization with just one instance of centos running a nodejs web server.
My guess is that QNAP will recognize the 16gb, but may not use all of it.
More memory is certainly better - not that the NAS will use all of it - but a VM with 8, 12, or some 14.5 GB has certainly the higher potential, requiring less swapping. That much about "not use it".
I tried with one module : This one > Kingston KVR16LS11/4
Worked perfectly, but 4 hours later my QNAP TS-251 freezed.
I tried to reboot and never worked again, so I returned his ADATA modules and worked perfectly.
What´s wrong about that 4 gb Kingston module? I have to use a pair? Can´t work in single mode?
Does the module / kit have to mention DDR3L, or is it enough if the RAM specs state it runs with 1.35V?
I see this voltage constantly stated as the max for Qnap TS451, but almost any (with some exceptions) DDR3 1600 module I see has this voltage listed, even though it's not listed as "DDR3L".
EDIT: also, is it better to buy a kit (say, 2x 4GB) or can you buy two identical (individual) modules (same model, manufacturer, specs)?
DDR3 1.35V should be fine ... as this is DDR3L. Not your mistake: I'm impressed that even major brand makers fail to provide complete and appropriate information.
Kits are commonly come with a lower price. Using two of the same make and model does not cause any issues.
Thank you Kurt for the advice and the nice welcome.
I'm now sporting a nice new RAM upgrade in my Qnap NAS. Went with Crucial CT2C4G3S160BMCEU, which is a 2x4GB DDR3L 1600 kit.
The store advertised it only as DDR3 SODIMM (and didn't list the part number either), but after a quick email exchange with them it turned out it was indeed DDR3L 1.35V. Why the online store doesn't properly list the products they sell you ask? Who knows...
NAS booted up without a hitch and new memory is visible and functional. Most excellent.
Well, I'm not sure if this is going to work for me.
I'm on TS-451+, not sure why other people get max 64gb with dmidecode, but I show max 8gb.
# dmidecode |grep -A 2 -B 6 -i maximum
Handle 0x0028, DMI type 16, 23 bytes
Physical Memory Array
Location: System Board Or Motherboard
Use: System Memory
Error Correction Type: None
Maximum Capacity: 8 GB
Error Information Handle: Not Provided
Number Of Devices: 2
For the money, I'd rather buy the max and do the job once--RAM is cheap. But if it's not going to support it, or worse, won't booth with unsupported memory... I suppose I'll have to stick with 8gb.
So, I'm curious if this is a 451 vs 451+ thing, or if in the newer versions they've changed hardware or patched something to limit the capacity. I bought this NAS last week.
EDIT: It says "Number Of Devices: 2"... does that mean each slot is a device, therefore max is 16gb? I'm kind of thinking of just buying it, and sending it back if it doesn't work.
