PC3 is standard voltage (1.50V) while PC3L is low voltage (1.35V) – A system that requires PC3L cannot support PC3 RAM. PC3L RAM works in a PC3 based system because it runs on the standard voltage and works in conjunction with PC3 RAM within the system. 12800 MB/s (DDR3-1600) vs. 10600 MB/s (DDR3-1333)
Yes, your laptop supports DDR3 (PC3- refers to DDR3) SODIMM memory, if the PC3L memory you have is SODIMM (204-pin) then you can install without problems, otherwise if it is DIMM (240 pin) then don’t even think about it.
If CPU-Z reports that the memory is running at 1.35V, that means you have DDR3L memory. Also, PC3L is a synonym for DDR3L. If you are planning to upgrade your RAM, buy a DDR3L stick. If you are planning to use the existing stick in another laptop, do so without hesitation, it can also run on 1.5V.
When I googled these terms I found the following: “PC3 or DDR3 operates at 1.50V while PC3L or DDR3L is the low voltage memory module that operates at 1.35V.” This makes it appear as if the two terms mean the same thing.
DDR3L is backward compatible with DDR3. However, DDR3 is not upward compatible with DDR3L. If a motherboard requires DDR3L (common in many new laptops), installing DDR3 may not work.
Look for DDR3 sodimms rated at 1.35V, that’s DDR3L. So basically DDR3 can run in DDR3L slot but it may damage MB and battery due to higher voltage and heat issues? It won’t damage anything. Your CPU is specified to use regular DDR3.
DDR4 is not backwards compatible with DDR3, so a DDR4 DIMM will not fit in a DDR3 DIMM socket.
DDR3 requires a voltage of 1.5V, while DDR3L only requires 1.35V. DDR3L consumes less power than DDR3. DDR3L generates less heat compared to DDR3. DDR3L is mainly used in mobile devices such as laptops and embedded devices, while DDR3 is mainly used in PCs.
No, PC3 = DDR3. You just need to match the PC3 number to the DDR3 frequencies. See en.wikipedia.org/wiki/DDR3_SDRAM#JEDEC_standard_modules. You should get either 12800 (1600) or 10666 (1333).
No, it won’t work. You need DDR3 memory, PC3 detonates DDR3 and PC3L means DDR3 low voltage. 1.5V is normal DDR3/PC3 and 1.35V is DDR3L/PC3L. DDR4 would be PC4.
No, DDR3 and DDR4 are not cross compatible.
There is no difference in function or performance between 1.5V DIMMs and 1.35V DIMMs operating at 1.5V in the same system.
Edit. I’ve just checked the Samsung catalog and I can now confirm that your Samsung M471B5273CH0 PC3L is a dual voltage module.
DDR3 stands for Double Data Rate type three, but does not imply a specific frequency or bus rate. The PC3-xxxx denotes the speed rating of the respective RAM and means that the memory is certified for that bus speed. So the DDR3 RAM PC3-1333 runs at 1333MHz while the PC3-1066 runs at 1066MHz.
Yes, you can. But the 1600 runs at 1333. Footnote: This is also the case if you use 1600MHz RAM on a motherboard that only runs at 1333MHz – it runs as fast as it is allowed to run.
Can you mix different brands of RAM? In short, the answer to this question is yes. Regardless of the RAM brand, speed, and size, you can theoretically mix and match RAM in your system. although it might prove problematic. Depending on the setup & workload, you might not even notice a performance difference.
You can use memory modules of different speeds as long as they are faster than those specified for your computer. It is recommended to use modules with the same speed as those already installed in your system. When you mix speeds, all modules will run at the speed of your slowest modules.
Debunking RAM myths one by one
You can do a lot with RAM: mismatched sticks, different speeds, different sizes and so on. In most cases you will just end up with a slower computer. Still, it’s always best to customize your RAM sticks.
DDR3L is a dual-voltage capable memory SoDIMM that supports both 1.5V and 1.35V operation.
