No one here seems to know it. I have a vaio ST series which rewuires a ddr3l and a lenovo x230 that runs on ddr3. I used the ddr3 on the lenovo to the vaio and the vaio detected it and worked well. I guess the diffrence is with the power. Putting a ddr3 will make your battery to discharge faster compared to getting a ddr3l.
DDR3 and DDR3L are high performance RAM used with latest motherboards and processors. DDR3 memory can be classified into two types:
1. Normal DDR3 Memory
- RE: DDR3 on a DDR3L slot You should consider trading the DDR3 stick for DDR3L. DDR3L uses less power so you could squeeze out some more time when on battery. Some of the newer Intel CPUs require DDR3L as well so keep that in mind.
- DDR3L modules are backwards compatible with DDR3 by design. Manufacturers use the same integrated circuits for DDR3 and DDR3L. The highest quality ICs are tested for operating at 1.35 volts and are branded as DDR3L if they run properly. Other than that, there’s no difference between them.
- DDR3 memory on the other hand is actually 1.5Vs. Now the primary problem is that Intel has officially listed support for DDR3L standard, not DDR3, which actually has a voltage of 1.35V.
2. DDR3L Memory
Normal DDR3 or DDR3 RAM is a high speed single voltage computer memory that runs on 1.5V (volt). It is the successor of DDR2 memory and the primary benefits of DDR3 memory over DDR2 one is faster speed / frequency & bandwidth, needs lower voltage and generates lesser heat. Generally the speed of a DDR3 Memory ranges from 1066MHz to 2133MHz. Some even faster DDR3 memories exist but they are very expensive and are not that much popular. DDR3 RAM is not compatible with systems that specifically require 1.35V memory for their working.

What is DDR3L Memory?
DDR3L or DDR3-Low Voltage RAM is a high speed computer memory that has same pins and size that of a normal DDR3 RAM but it is dual voltage memory. DDR3L memory can run on both 1.5V and 1.35V, which means it can run on both low and high voltages. DDR3L memory is also backward compatible with DDR3 which means you can run DDR3L memory on a system or motherboard that uses or requires traditional or normal DDR3 RAM. In DDR3 SoDIMM “PC3L” is written on the JEDEC compliant text (Sticker on the RAM module) for identification purpose and in normal DDR3 memory the text written is “PC3” only. DDR3L is generally used with Intel 4th and 5th generation processors and AMD FX series CPUs. The main advantages of DDR3L memory over DDR3 is lesser power requirement, lesser heat generation, support for new processors & motherboards and somewhat increased performance.
There is also a less common DDR3LU (DDR3 Ultra Low Voltage) RAM that operates at 1.25V which is even less than DDR3L RAM.
Comparison of DDR3 and DDR3L Memory
DDR3 Memory | DDR3L Memory | |
| Voltage | 1.5V (Single Voltage) | 1.35V and 1.5V (Dual Voltage) |
| Pins | 240, 204 | 240, 204 |
| Backward Compatible | No | Yes, backward compatible with DDR3 |
| Size | DDR3 DIMM / SoDIMM | Same as DDR3 DIMM / SoDIMM Memory Module |
| Usage | Up to Intel 3rd Generation (Ivy Bridge) or older Processors | Intel 4th Generation (Haswell), 5th Generation (Broadwell), Skylake Processors, AMD FX series and higher processors |
| Advantages | Better and Faster than DDR2 RAM | Generates less heat and consumes less power than normal DDR3 RAM. Also performs a bit better than DDR3 RAM |
| Identification | PC3 written on JEDEC compliant text (Sticker on RAM module) | PC3L written on JEDEC compliant text |

DDR3L modules are backwards compatible with DDR3 by design.
Manufacturers use the same integrated circuits for DDR3 and DDR3L. The highest quality ICs are tested for operating at 1.35 volts and are branded as DDR3L if they run properly. Other than that, there’s no difference between them.
yes it is correct, that they should use the same Chips. So from a functionallity point of view it is really just the same compatibility issue as with DDR3 from one vendor to another vendor (or even just for one die shrink to the next die shrink).
JEDEC defines that the DIMM needs to be backward compatible. So if a JEDEC compliant DIMM is operating at 1.5V should be tested and verified from the vendor. But not too many DIMM vendors really state that the DIMM is JEDEC compliant.
E. g. I have seen DIMMs with devices not supporting specific CL that they would need to support to be JEDEC compliant ..
And in this case thre is no need that the DIMM really is backward compatible (even if it is just a question of Speed, or reliability over time).
Even standard DIMMs are theoretically interchangable, there are many compatibility issues between motherboard, controller and DIMM out there .. and DDR3L will not make it better ..
Guess thats the usual difference between theory and praxis ..
and so I prefer to look at the DIMM spec and at least verify that the 1.5V is a supported voltage on a DDR3L DIMM if I intend to use it in a DDR3 System…
