You need to confirm the USB HUB power whether it is enough. The USB 2.0 power output standard 5V/500mA ; The USB 3.0 power output standard is 5V/900mA. If the USB HUB power is not enough. it's possible caused USB can't working normal. And if the USB 3.0 is connected to the devices via the USB HUB 2.0, the USB speed only USB 2.0 standard.

ESD stands for Electrostatic Discharge. Static electricity is the energy found in the air surrounding us and can damage electronic components in computers hard disk drive, floppy disk drive, memory modules, motherboards etc. To protect memory modules from being damaged by ESD, always keep an electronic component in its anti-static package until you are ready to install it. For an added measure of protection, use an anti-static wrist strap, which can be found almost in every electronic retail store.

Make sure that you have the correct memory for your system, you may try to the step the following,

1. Shut down, and remove all the memory modules from your system.
2. Insert one memory modules at a time, maximum capacity memory first insert. The memory is seated properly in the computer socket with both clips locking on their own.
3. Boot the system up to ensure its compatibility, to check the memory module does work.
4. Insert one memory module at a time and boot the system up to ensure its compatibility. And running step 1 to sep 3 after add one memory modules each time.

If this computer have the latst BIOS of the system. And you have identified a defective module, you can contact the original purchase shop or to contact the authorized agent for RMA service in you local. Or contact us customer service mailbox.

For the Windows operation system, right clicking on the Start button and then choose the System option on the pop-up menu. You can see the installed memory RAM information.
For the Mac operation system,  select About This Mac from the Mac menu.
For the Linux operation system, open the terminal app or login to the remote Debian server using ssh command. Type the free command: cat /proc/meminfo

Memory doesn't have to be installed in pairs, but some high end motherboards support dual channel or quad channel memory which can (under some circumstances) dramatically increase performance.
Note. using on the dual channel or quad channel that memory have to are same capacity, we also suggest use the sample brand of DRAM with installing in dual or quad to avoid the system crashing.

No, DDR3 and DDR2 that are different clock speeds, voltage and memory slots(or missing tooth).

More memory allows you to run more programs at once. usually doubling the amount of memory in your system will give you sample "space" to work and will make an obvious difference in overall speed.
Suggest the following,
Almost used for internet, office programs : 4GB to 8GB
Almost used for small games, video play : 8GB to 16GB
Almost used for multimedia editing packages or graphics-intensive game : 16GB or above

DDR3L is low voltage memory at 1.35V. DDR3 memory adheres to the 1.5v standard. For the SO DIMM DDR3 memory, we provide is of dual voltage and will operate in both 1.35V and 1.5V environments.
