Is DDR3 1.5 V?

In the past, most DDR3 memory voltage ranged from 1.5 - 1.65v. More recently, dual 1.35/1.5 voltage modules came available at Crucial.com. While the lower voltage memory has some advantages over high voltage (namely lower power consumption), your system must support it in order to realize the benefits.

What is 1.5 V in RAM?

1.5V is the JEDEC standard for DDR3, therefore you will never fry a module at this voltage. Some sources: Hynix: "Hynix DDR3L SDRAM provides backward compatibility with the 1.5V DDR3" Crucial refers to this as Dual Voltage: In the past, most DDR3 memory voltage ranged from 1.5 - 1.65v.

Is DDR3 and DDR3L the same?

The main difference between DDR3 and DDR3L is in the voltage specification. Voltage specification for DDR3 is 1.5V, but the voltage for DDR3L is less, which is 1.35V. The letter L in DDR3L refers to low voltage standard. As DDR3L is a special type of DDR3 all other specifications except the voltage remains the same.

Can DDR3 run 1.35 V?

In order to run at 1.35V, all installed memory modules must be dual-voltage 1.35V/1.5V and the system must support DDR3L (1.35V low voltage) to enable the module to run at 1.35V.

Will DDR3 RAM work in DDR3L slot?

DDR3L is RAM that runs on lower voltage (1.35V) than DDR3 (1.5V.) Both are compatible and interchangeable in slots designed for DDR3 RAM. (However DDR3 won't work in a slot designed for DDR3L because it needs a higher voltage than the slot provides.

What happens if I put DDR3 in a DDR3L slot?

In almost all cases, the answer is no. DDR3L is a low voltage RAM which helps enhance battery life. The entire system is designed with this in mind. Using DDR3 in this system will most likely cause a failure to boot since the RAM will be trying to draw power to operate that simply is not available.

Can DDR3L fit in DDR3 slot?

DDR3 runs at 1.5V, DDR3L will run at 1.35V or 1.5V and is therefore backwards compatible with DDR3. If you're adding DDR3L to a system already containing DDR3 then it should work.

Is 1.5 V OK for RAM?

It's safe if the temperatures are okay. Mine is 33 C normal and 43 C during memory stability test. If you use a voltage higher than 1.5 v, you will get a lot of errors in memory stability test.

What is the lowest voltage version of DDR3?

In our recent blog post, we explained what DDR3L is — Low Voltage DDR3 that supports 1.35V and 1.5V operation. When configured at 1.35V, DDR3L memory can reduce server power consumption by 15% or more over equivalent 1.5V memory, especially on servers.

Are all DDR3 RAM compatible?

One thing to keep in mind is that memory needs to be the same type - memory modules are not forward or backward compatible in terms of generation types so DDR3 will not work in DDR2 or DDR4.

Can you mix different DDR3?

Don't even try. You cannot mix different generations of DRAM. In fact, you can't install a different generation of DRAM in your system at all. The reason is that your motherboard is built to process one generation of memory.

Can you run 1.35 V RAM in 1.2 V slot?

It should work just fine.

However if the system already has 1.2v ram installed this could be the power limit. As long as you don't perform any overclocking on the 1.35v ram it should have no issues.

What is the difference between 4gb DDR3 and 4gb DDR3L?

The main difference between DDR3 and DDR3L is the voltage. DDR3 ram runs at 1.5V whereas DDR3L runs at 1.3V. DDR3L rams are used mainly in laptops and small form-factor Pc's. You can run a DDR3L memory stick at 1.5V without any problem(most DDR3L memory supports it).

Will DDR4 work in DDR3?

DDR4 is not backward-compatible with DDR3 so a DDR4 DIMM will not fit on a DDR3 DIMM slot. Not only is the key notch of each DDR generation different (please refer to Figure 1 above), but the DDR4 pin size and arrangement is different from DDR3.

Is DDR3 PC3L same as DDR3L?

DDR3L, or PC3L is the same and stands for low power memory 1.35v. L after DDR3, or PC3 means low power. DDR3 or PC3-12800 is standard voltage ram 1.5v. PC3L, or DDR3L ram is 1.35v, but can operate on 1.5v as well, so even if your server does not support 1.35v memory, this ram will adjust its voltage to 1.5v.
