The Ultimate Guide for DDR3 Vs DDR3L Ram

Is there only the letter ‘L’ that brings the war for DDR3 Vs DDR3L RAM? Yes, but do you know this extra L has brought a revolution in between these two RAM?

The L here stands for low voltage standard type, but is it only about reducing power consumption or more of that? In this context, we will make a head to head difference between DDR3 and DDR3L so that you can make your decision on which one you must have.

Basic Comparison Between DDR3 vs DDR3L RAM

Both RAM is a type of Dynamic Random Access Memory (DRAM) widely popular to use on laptops, mobile devices, and desktops. DDR3 stepped inside the industry in 2007 as a triumph over some features for DDR and DDR2.

On top, DDR3 and DDR3L RAM allow chips up to 8 GB storage, and there are no significant differences. However, Patriot Memory Signature DDR3 RAM Pack is quite affordable to have. In terms of the supported frequency, both RAM support 800 MHz, 1066 MHz, 1333 MHz, 1866 MHz, and 2133 MHz.

If you look for the visual basics, you get the extra ‘L’ on both beside the name and the JEDEC (Joint Electron Device Engineering Council) compliant text on the RAM device. And this ‘L’ stands for Low Voltage Standard.

Comparison Between DDR3 vs DDR3L  On Power Consumption

Well, here comes the focus point for DDR3 and DDR3L Ram.

DDR3 RAM uses 1.5 V of power, and it is the fixed Voltage specifications for DDR3 Ram functioning. So, based on the voltage value, the power is consumed that much.

On the contrary, if you look at DDR3L, it comes with authentic Voltage compatibility. You can also take it as a dual voltage supporting technology here with the DDR3L RAM. It works with both 1.35 V and 1.5 V. Moreover, due to its less voltage supporting fact, it consumes radically less power than a DDR3 RAM.

So, less power consumption resulting in less heat generation in the data cycling process. A Tech DDR3L RAM with 1600 MHz frequency is such an upgraded laptop or notebook ram. DDR3L RAM provides an efficient and long-term performance by saving around 25% more power consumption in the long run.

DDR3 vs DDR3L Performance Difference

The significant difference lies in the voltage, which does not mean there is no performance difference between them. While with the DDR3, you get better, in DDR3L, you get the best.

Compared with a DDR3 Ram, DDR3L Ram consumes less power, which means less heat generation inside the chips. DDR3 usually comes with the 1.5 V of power usage to transmit the voltage lower zero to a higher 1 state. On the other side, this data transmission process using the voltage can be done way faster with DDR3L due to its less voltage use.

DDR3L RAM will generate less amount of heat while data processing comparing to a DDR3 Ram. So, here you can enjoy the dua;t voltage support that fastens the performance. Some DDR3 Ram also comes with the 1.3 V of voltage usage capabilities. Like the Patriot Memory Store DDR3 with 5 Rank module is such a Ram. So, here you can reduce the more heat production of the battery or device to some extent.

DDR3 vs DDR3L Speed Difference

As we said, the main difference between DDR3 and DDR3L is the voltage use; you can assume that speed for the data processing can be higher for whom.

Yes, this point goes for the DDR3L Ram for its less power consuming, resulting in faster operation. However, the speed difference is not that much yet. But if you compare based on the frequency rate, it becomes a fact then.

If you have any DDR3 Ram with 1600 MHz of cycling rate like Teamgroup Elite DDR3 16 GB ram has, then no comparison stands here with DDR3L.

DDR3 vs DDR3L Compatibility

When the thing is about compatibility, you have two options to ensure-pin compatibility and processor compatibility. Both Ram of SO-DIMM (Small Outline- Dual Inline Memory Module) IC has 204 pins on the card slot.

Those who seem to hover with the confusion can I use DDR3 instead of DDR3L– you can be sure after this discussion. So, it’s a yes for them as the pic number on both Ram cards is the same. However, if you don’t know about these pins, these are the metal pieces or the tiny connection string that connects the RAM card to the motherboard.

Let’s come to the compatibility with the processor. Here you might get some shock as the DDR3 Ram is only compatible with the 3rd gen Intel processors. The DUOMEIQI 1333 MHz SO-DIMM can be kept in the trial. But for the upgraded gen of processors, you need to switch to the DDR3L or DDR4, or others.

On the other side, you can use DDR3L in 4th gen processors or more and even in the AMD FX series processor.

Now, if your mind might ask that can I use DDR3L in DDR3 slot. The answer is yes if only your computer is equipped with the 4th gen processor or more.

Besides, in the DDR3 DDR3L compatibility of devices, it is best to use a DDR3 Ram in your personal computer, laptop, and networking servers. On the other side, DDR3l gives its best in mobile devices, laptops, or other embedded systems for faster performance results.

DDR3 Vs DDR3L Price Comparison

If you want to know DDR3 Vs DDR3L which is better then, both are better with individual criteria. However, the DDR3L Ram, of course, one step ahead. And the proverb says good things cost more needs no saying.

The DDR3Lram will surely cost higher than a DDR3 Ram. But you get more power consumption with faster performance too.

Which Should You Pick?

Upgrade of your storage device becomes crucial as our devices need to be updated with consistent technological performances. Our entire discussion about DDR3 Vs DDR3L Ram difference will surely help you come out of the total confusion and make your choice.

Based on user experiences and opinions, we can say that DDR3L Ram will bring an instant performance difference, only if you have a minimum of 4th gen Intel processor.  But if you don’t want to cross your budget or your device is available with 3rd gen or older processor, then, no matter, go for the DDR3.

DDR3 is no less in performance, but if you come out of the box then nowadays, DDR3U referring to the Ultra voltage consumption has been occupying its space.
