Can I use 1.5 V RAM instead of 1.35 V?

Generally, lower voltage is optimal as it consumes less power and in turn, may generate less heat. However, it is important to note that the overall system must support DDR3L

DDR3L

The DDR3L (DDR3 Low Voltage) standard is an addendum to the JESD79-3 DDR3 Memory Device Standard specifying low voltage devices. The DDR3L standard is 1.35 V and has the label PC3L for its modules.

(1.35V low voltage) to enable the module to run at 1.35V. If the system does not support DDR3L (1.35V low voltage), the module will run at 1.5V.

Does voltage matter on RAM?

We recommend being conservative when increasing DRAM voltage. Increasing voltage too much can damage your system. By default, DDR4 runs at 1.2v, while many memory module kits are rated to run at around 1.35v with XMP. Raise your voltage slowly until your system is stable; we recommend not going above 1.4v to be safe.

Is it safe to run RAM at 1.5 V?

It depends what sort of RAM it is. If it's DDR3, 1.5V is the default setting. If it's DDR4, 1.5V is an overvolt, but not uncommon for heavily overclocked memory, and is unlikely to cause any damage. The default voltage of DDR4 is 1.2V, and most XMP kits use 1.35V, but very high-end kits can go up to about 1.65V.

Can I use DDR3L instead of DDR3?

DDR3L is pin-compatible with DDR3. DDR3L is a dual voltage capable memory SoDIMM, which supports operation at both 1.5 V and 1.35 V.

Can I use different voltage RAM?

What about DRAM modules with different voltages? You guessed it: both modules would run at the higher voltage. For example, if you have a 1.5v module in one slot and a dual voltage (1.35v/1.5v) model in the other, your system will run at 1.5v.

1.35 V RAM in a 1.5 V system - Will it fry or overclock? (2 Solutions!!)

Is it OK to mix and match RAM?

Can You Mix Different RAM Brands? In short, the answer to this question is: yes. No matter the brand, speed, and size of the RAM, theoretically, you can mix and match RAM in your system, though it may prove to be problematic.

Can I mix 1.2 V and 1.35 V RAM?

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. Hope this helps.

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.

Are DDR3 and DDR3L RAM 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.

How do I know if my RAM is DDR3L or DDR3?

DDR3L can run on both 1.35 V and 1.5 V, while DDR3 runs only on 1.5 V. If CPU-Z reports that memory runs on 1.35 V, that means that you have DDR3L memory. Also, PC3L is synonym for DDR3L.

What is unsafe RAM voltage?

Based on the information provided by members of the community, it is safe to go up to 1.4V with DRAM voltage. Going beyond 1.4V may cause damage to the RAM and is not recommended.

Is 1.5 V too high for CPU?

Anything above 1.45V is overkill for any modern CPUs. Higher voltages are possible assuming you're running some exotic cooling like LN2 but this will still take its toll on the lifetime of the chip due to electromigration.

Can high voltage damage RAM?

If you set your RAM voltage too high, it can cause memory errors (which can cause crashes) or can damage the RAM, but it won't damage the CPU.

Is all DDR3 1.5 V?

DDR3: DDR3 is a single voltage capable memory SoDIMM, which supports 1.5 V operation only. It is NOT compatible with computers using 4th Gen Intel processors, which exclusively support 1.35 V operation for memory.

What is safe voltage for DDR3 RAM?

The stock voltage with DDR3 is 1.5 volts. As guidance the maximum JEDEC recommended voltage is 1.575 and supposedly modules should be able to handle 1.975 volts without permanent damage, though they don't have to function at this level.

What is the best RAM voltage?

It is recommended to set the voltage below 1.5V, and at the same time, do not rush to make a large adjustment. For the DRAM Voltage, directly input the value with keyboard.

What is the difference between 1.5 V and 1.35 V RAM?

1.35V/1.5V or 1.5V? Generally, lower voltage is optimal as it consumes less power and in turn, may generate less heat. However, it is important to note that the overall system must support DDR3L (1.35V low voltage) to enable the module to run at 1.35V.

What does L stand for in DDR3?

see less L stands for "low voltage," which is 1.35V instead of 1.5V. If your computer supports or requires 1.35V RAM, it will use less power, reduce heat and extend battery life, DDR3L is the designation some manufacturers use to say the RAM runs at 1.35V.

Is DDR3L slower?

The DDR3L RAM consumes lesser voltage compared to the DDR3. This reduces heating and enables faster operation. Also the lower the operating voltage, (1.35v, 1.25v) the faster the memory can theoretically operate because the transition from a zero to a one state requires less voltage shift.

What happens if you put DDR3 in a DDR4 slot?

When mixing DIMMs of different operating speeds, the motherboard will underclock the faster one so it will only run at the speed of the slowest DIMM, unless you overclock the slow DIMMs.

What happens if you mix DDR3 in a DDR4 slot?

All RAM isn't the same and DDR3 and DDR4 can't be used interchangeably. You can't insert a DDR3 RAM stick into a DDR4 slot because it's not backward-compatible. The stick won't fit into the slot and, even if you did get it wedged in there somehow, your motherboard won't recognize the format.

What happens if you install RAM in wrong slots?

What happens if the RAM slots on a motherboard are not in the correct order? If you so happen to install RAM in the middle slots (2 & 3, instead of 1 & 3, or 2 & 4), you just won't benefit from the dual channel mode, which means slower performance.

Can you mismatch RAM kits?

Theoretically, you can mix different RAM brands in your computer system, but you may encounter some problems. Sometimes mixing different RAM brands can lead to a drop in performance, but if you consider your options carefully, you may be able to avoid issues.

What does increasing RAM voltage do?

As with CPU overclocking, increasing the input voltage of a component will result in higher energy consumption and greater heat output. Memory voltage is a key ingredient to achieving a stable overclock. In a standard memory overclocking use case, consider 1.5V as a maximum, but aim for lower whenever possible.

Can I use 2 Rams with different speeds?

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 of the same speed as those already installed in your system. If you do mix speeds, the modules will all run at the speed of your slowest modules.
