Definition of LowVoltage in RAM context

The term „LowVoltage“ has a similar meaning across the field of computer equipment. Meant are hardware components that differ from Normal Voltage products, especially in voltage consumption and equipment details. LowVoltage modules in the RAM context refer to DIMM- and SO-DIMM-modules, which function under reduced operating voltage. For example, LowVoltage-RAM of type DDR3-RAM are being operated with 1,35 Volt compared to Normal Voltage DDR3 with 1,5 Volt. Mostly, the energy-saving RAM variants are marked with an L in their model name.

The concept of DDR-SDRAM has continuously been refined since the beginning of the new millennium. For comparison: The predecessor module DDR2 still has an operating voltage of 1,8 Volt. Not only the necessary voltages drop with the new modules, there is also a rise of data transfer rates. Let’s take a look at the continuing advantages of LowVoltage modules:

Advantages of LowVoltage modules and what’s their use in practice?

There are some advantages coming along with LowVoltage RAM. According to the type of application, they have more or less noticeable effects:

Long battery life
Especially for mobile use, which relies on longer battery lives, the enery-saving LowVoltage modules are very well suited.

Low heat development
In fact, reduced voltage leads to lower heat development. This affects the CPU stability of the system in an extremely positive way. This again has many more advantages: For example, the error rate of the storage controller drops considerably.

Lower operating costs
The reduced operating voltage implies energy-saving accompanied by savings in the operating costs. This rather doesn’t fall into the weight in the field of homeoffice. However, with some more computer systems or server landscapes the cost differential is clearly noticeable. Thus, the electricity bill can be brought to its knees.

Eco-friendly

Saving electricity also means doing good for our economy. Low-power hardware distinguishes itself with an eco-friendly production cycle and lower power consumption. Clear differences are being noticed with an increased load, respectively when your system has a big RAM storage, which isn’t in idle mode.

When you have a server system and you want to optimize the power consumption, you should take the component main memory into consideration.

Mixing Normal RAM and LowVoltage – does that work?

Even when there is still a variety of CPU and motherboard combinations that don’t support LowVoltage, LowVoltage RAM from CompuRAM can be used in such systems all the same. Our energy-saving RAM namely is backward compatible. They can be mixed with “normal” RAM without difficulty. This can be explained as follows:


What happens exactly when I mix LowVoltage modules with normal RAM?
That’s also up to the manufacturer of the system. Every system manufacturer can configure this differently. For example, he can prevent a mix mode at Normal Voltage if he wants his systems to run in LowVoltage mode in any case. The so-called “Power-on-self-test” of the BIOS checks with every system start if the components of the PC are functioning. In the just-named configuration unsuitable modules – in this case “Normal Voltage” RAM – would prevent the system start.

Is my system working with LowVoltage modules?

The product database of CompuRAM is extensive and prepared for all eventualities. When you buy LowVoltage modules for your particular system at CompuRAM, you don’t have to worry about this. CompuRAM LowVoltage modules can also fall back to work as 1,5 Volt modules.

Currently, I have installed LowVoltage modules, can I build in modules with normal voltage of CompuRAM, too?

If LowVoltage modules are already installed in your system, you should extend it with LowVoltage modules. It is not sure if your present modules are able to work in Normal Voltage as a fallback. We will gladly consult you.

Currently, I have installed modules with “normal” Voltage. What happens if I mix these with LowVoltage modules from CompuRAM?

Our LowVoltage modules are working under “Normal” Voltage as well as under reduced voltage.

Conclusion:

LowVoltage modules can, in some areas of operation, for example at larger server landscapes or in mobile devices, unlock their advantages such as lower operational costs and longer battery lifetimes. CompuRAM LowVoltage modules can be mixed with normal RAM without difficulties. When ordering modules at CompuRAM, you don’t have to worry: Our product database doesn’t fail, we only provide you with compatible modules.
