Memory explanation needed

So I'm reading W350STQ description and slightly confused regarding the memory explanation.


a. Dual channel DDR3L
b. Three 204 pins SODIMM sockets, support DDR3L 1600MHz
(Real operation frequency depends on processor)
c. Two DIMMs per channel option is only available in 4 cores processor
d. Expandable memory up to 24GB, depends on 2GB /4GB/8GB SODIMM
module

So my question is
1. Does it support normal DDR3?
2. Regarding point a and b, does this mean I can have up to 3 sticks but it can only utilize 2 channel (64bit x 2)? Same speed as 2 sticks?
3. I'm not sure what 2 DIMMs per channel mean @_@

Thanks in advance

 

Good morning,
DDR3L memory is simply our good old' DDR3 memory but working at a lower voltage (1.35V instead of 1.5V).
#1. Yes, the computer will support normal DDR3 memory, but your general power consumption will go up.
#2 and #3. Your have three slots but they are using a dual-channel configuration, which means your slot 1 and 3 are channel A and your 2nd slot is channel B (or vice versa). Therefore you can populate all three RAM slot and have your computer running in dual-channel.
That explains why you can go up to 24GB or RAM, although in that situation you would have twice the amount of ram on channel A.

 

Morning,
I see, does that mean the transfer rate of 3 SODIMMs is as fast as 2 SODIMMs since they both have dual channel?
It's just it has more capacity if need be?

 

Yup, that would be it. You are in dual-channel anyway so the rate will be the same.
Actually even in single Channel it has been proven that the speed difference is pretty much non-existent.

 

Alrighty, thanks! Have a good day~
