Contents What are low voltage ram modules? What are high voltage ram modules? Can you mix low voltage and high voltage ram modules? Ultra low voltage ddr3 module – the ram of future Final words

Low voltage RAM operates at 1.25V or 1.35V

It decreases the stress on processor and motherboard

Low voltage RAMs are preferred over high voltage RAM modules

They encourage greener computing

What are Low Voltage RAM Modules?

These are standard RAM Modules that consume voltage between 1.5V and 1.8V

Usually older generations or RAM modules including DDR, DDR2, DDR3 had high voltage RAM

Nowadays, these are mostly used for overclocking purposes

What are high voltage Ram Modules?

Yes, a low voltage RAM module can work normally with a high voltage RAM module because it is backward compatible.

But, a motherboard that doesn’t support a low voltage RAM (1.35V) will run it at 1.5V because of this backward compatibility feature.

Can you mix low voltage and High voltage ram modules?

It is not advisable to mix these RAM Modules as doing so may diminish the useful life of these components and lower system performance.

- Low voltage RAM module is better because it consumes less electricity and produces less stress for the processor and the motherboard.

Low Volt or High Volt RAM: Which is better?

The difference between both RAM modules is

negligible in day-to-day tasks.

It will only matter if you overclock the RAM

modules or use a dozen in servers.

A new RAM Module is in town named Ultra Low - Voltage

DDR3 Module (DDR3U) – Because it is brought in service

from the third generation.

The RAM consumes 1.25V that is 10% less power than

commercial RAM chips.

It is being said the use of DDR3U will reduce the carbon

footprint of computing devices.

Ultra low voltage ddr3 module – The ram of future

A low voltage DIMM module is backward compatible and includes 1.25V

and 1.35V RAM memory.

On most memory module packets, the low voltage RAM can either be

written as 1.35V or ‘DDR3L’, where ‘L’ stands for ‘Low voltage’ or ‘LV

RAM’.

If Low Voltage DDR3L RAM is not supported by a motherboard, it will run

at the normal voltage of 1.5V.

Things to Note

If your system supports low voltage RAM module, then go for it. Otherwise, you can purchase a Standard RAM module. For most people, the price is a limiting factor. So if the price difference is low, invest in the modern technology (low voltage RAMs) that’ll stay relevant for several years.
