I have a Toshiba notebook that has a AMD E1-2100 APU and I was wondering that does this type of APU use DDR3 or DDR3L?
Are all E1-2100 the same or are they different on different machines? I have the Toshiba C55D-A5163.
The laptop specs show 1333 MHz DDR3 SDRAM. You might be able to view the installed RAM part. no to determine if it's LV or standard SDRAM. According to the second link the processor can run either std. 1.5v DDR3 or 1.35v LV DIMMs. If adding to vs. replacing the existing DIMM you'll want to have matching RAM.

Well Toshiba techs said that my notebook uses DDR3 and not DDR3L but my notebook was using DDR3L so maybe it can use both types. Is it possible that this type of CPU can use both types? I did see other Toshiba notebooks like the Celeron N2820 and that did say it uses DDR3L on Toshiba specs. The specs PDF file for mine said DDR3 so I can only think that it can use both.
As my comment above states, the second link shows that the E1-2100 processor can use both std. 1.5v DDR3 and also 1.35v DDR3 LV. The DDR3L designation indicates that the processor can use both types of DIMMs. I would recommend that you use the same DIMMs and not mix DIMMs to insure reliable operation because mixed DIMMs do not always function reliably and/or may force the BIOS to lower the operating frequency, which is undesirable especially in a laptop.
I know to use both the same type of rams since mine has two slots but just wanted to make sure if I can use any types of DDR3 rams like 1.5v or 1.35v.
No you can not use just any DDR3 DIMM. You need a DDR3 SO DIMM according to various online RAM selectors. The first link above indicates the OEM RAM is 1333 MHz. Some RAM makers have online RAM selectors where you input the PC brand and model and it will tell you what part number RAM is required. You should be able to find info. on the DIMM installed in your laptop with an online search of the part number, just as I found the two links above and the link below.
The link below shows what Crucial states is the appropriate SO DIMM for your laptop but there are many choices. I'd confirm that the DIMM you intend to buy specifically is correct for your model laptop as application listings are not always correct and laptop makers can change specifications without notice. The maximum RAM supported by your processor is 16 GB so that means 8 GB. x 2 DIMMs is the max you can use. 8 GB. is typically plenty of RAM however.
