It’s a typical situation: you desire to include or change a dram module in her computer. But you already have another module. Have the right to you mix and also match theatre with various generations, speed, latency, voltage, or manufacturers?

In this blog, we’ll discover what wake up in every of this scenarios, and also best practices to ensure the your computer memory is the perfect complement for her system.

You are watching: Why is it important to match the latencies of the older modules to the newer modules

Before we dive right into what happens as soon as you mix different types of memory, let’s take it a look at what precisely differentiates one dram module from another.

Generation: This refers to the variation of the plays chip. Each generation of DRAM to represent an development in speed, latency, and voltage.

Speed: This describes how easily your computer can store and also retrieve data from your memory module. In general, much faster DRAM is better.

Latency: additionally known as “timings,” latency describes the variety of clock cycles to finish a read/write job for her system’s CPU. The lower the latency of her DRAM module, the less time the takes to complete these tasks.

Voltage: This is the power consumed by the theatre module.

Brand: The manufacturer and/or assembler of her memory, prefer

Different Generations of DRAM

Let’s to speak you have actually older DDR3 lamb in your system. Have the right to you install a DDR4 module alongside her DDR3 to get better performance?

No. Don’t do it. Don’t even try. You cannot mix different generations of DRAM.

In fact, you can not install a various generation of dram in your mechanism at all. The factor is the your motherboard is built to process one generation the memory. In fact, every generation that DRAM has a different placement of pins so the you can not accidentally install the not correct module in a computer.

The verdict? No. Never. Impossible.

Speed, Latency, & Voltage

What happens when you install DRAM modules of different speeds?

Nothing exciting.

While you deserve to technically mix speeds, over there is one thing come note: your DRAM would certainly all operation at the speed of the slowest module. For example, if you have actually a DDR3 1333MHz system and also install a 2nd module in ~ 1600MHz, they would certainly both run at the 1333MHz speed.

The very same thing happens through modules that have different latencies. The device will run based on the module v the slowest timings. An additional thing to save in mind is what speeds her motherboard deserve to handle. If your motherboard can only manage a 1333MHz module, then a 1600MHz module would run at 1333MHz.

What about DRAM modules with different voltages? girlfriend guessed it: both modules would run in ~ the higher voltage.

For example, if you have a 1.5v module in one slot and a double voltage (1.35v/1.5v) model in the other, your mechanism will run at 1.5v. If you want your theatre modules to operation at 1.35v, every one of them would have to be 1.35v and also your motherboard would need to support the reduced voltage.

The verdict? Possible, though you will shed the services of the an ext efficient module. If you have the right to afford to change all the modules v faster, lower-latency modules, girlfriend will get the ideal benefit. If you are trying to save money, friend will obtain the best value by purchasing second module through the very same speed and also latency.

If friend are skilled at overclocking, the is feasible to readjust the BIOS and other setups to tweak the power of mixed-speed modules. However it deserve to lead come unpredictable results.


We have developed that you absolutely can’t mix generations that DRAM. And it’s not optimal come mix modules with various speeds, latency, or voltage.

How about mixing brands of DRAM?

Theoretically, if the various other traits (generation, speed, latency, voltage) are the same, there must be no concern using DRAM indigenous two various brands. Though part older DDR3 systems need matched set of memory.

Another point to keep in mental is that countless memory brands perform not produce their very own DRAM; they just assemble the modules. There are just a handful of true storage manufacturers, so girlfriend will eventually be choosing DRAM from those sources.

Slight sports in the assembly process, no to point out the differences in production amongst the manufacturers, might affect the performance of the modules. While that is unlikely, there is always the possibility of the modules not functioning together and also causing the Blue display screen of death for her system.

The verdict? continue at your very own risk and consult the manufacturer’s documentation.

We’ve covered the miscellaneous scenarios in mixing and also matching various DRAM modules, and the potential pitfalls. Overall, the most basic solution is to avoid mixing theatre altogether. Storage is incredibly affordable these days, for this reason it’s not to risk handling the problem of not compatible modules.
