It’s a prevalent situation: you desire to include or replace a DRAM module in your computer. But you currently have one more module. Can you mix and enhance DRAM via various generations, speed, latency, voltage, or manufacturers?

In this blog, we’ll check out what happens in each of these scenarios, and finest techniques to ensure that your computer system memory is the perfect enhance for your device.

Before we dive into what happens when you mix different types of memory, let’s take a look at what precisely differentiates one DRAM module from one more.

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

Speed: This refers to exactly how conveniently your computer system can save and also retrieve information from your memory module. In basic, quicker DRAM is much better.

Latency: Also recognized as “timings,” latency describes the number of clock cycles to finish a read/create task for your system’s CPU. The reduced the latency of your DRAM module, the much less time it takes to complete these work.

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

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

Different Generations of DRAM

Let’s say you have actually older DDR3 RAM in your device. Can you install a DDR4 module alongside your DDR3 to gain better performance?

No. Don’t execute it. Don’t even attempt. You cannot mix various generations of DRAM.

In truth, you can’t install a various generation of DRAM in your device at all. The factor is that your motherboard is constructed to process one generation of memory. In fact, each generation of DRAM has a different placement of pins so that you can’t accidentally install the wrong module in a computer.

The verdict? No. Never before. Imfeasible.

Speed, Latency, & Voltage

What happens as soon as you install DRAM modules of different speeds?

Nothing interesting.

While you have the right to technically mix speeds, tbelow is one essential thing to note: your DRAM would all run at the speed of the slowest module. For example, if you have a DDR3 1333MHz device and also install a second module at 1600MHz, they would certainly both run at the 1333MHz speed.

The exact same thing happens via modules that have actually various latencies. The system will certainly run based on the module with the slowest timings. Another point to store in mind is what speeds your motherboard deserve to take care of. If your motherboard have the right to only take care of a 1333MHz module, then a 1600MHz module would certainly run at 1333MHz.

What about DRAM modules through various voltages? You guessed it: both modules would run at the better voltage.

For example, if you have actually a 1.5v module in one slot and a dual voltage (1.35v/1.5v) design in the various other, your system will certainly run at 1.5v. If you wanted your DRAM modules to run at 1.35v, every one of them would certainly have to be 1.35v and also your motherboard would have to support the reduced voltage.

The verdict? Possible, though you will certainly lose the benefits of the more efficient module. If you can afford to replace all the modules with much faster, lower-latency modules, you will certainly obtain the best advantage. If you are trying to conserve money, you will certainly get the best value by purchasing an additional module via the same rate and also latency.

If you are competent at overclocking, it is possible to adjust the BIOS and also various other settings to tweak the performance of mixed-speed modules. But it deserve to result in unpredictable outcomes.


We have establimelted that you definitely can’t mix generations of DRAM. And it’s not optimal to mix modules with various speeds, latency, or voltage.

How around mixing brands of DRAM?

Theoretically, if the other traits (generation, speed, latency, voltage) are the very same, tright here have to be no worry utilizing DRAM from two various brands. Though some older DDR3 units need matched sets of memory.

Another thing to keep in mind is that many kind of memory brands perform not manufacture their very own DRAM; they simply assemble the modules. Tright here are just a handful of true memory manufacturers, so you will certainly eventually be selecting DRAM from those sources.

Slight variations in the assembly process, not to cite the differences in manufacturing among the manufacturers, might influence the performance of the modules. While it is unmost likely, tright here is always the opportunity of the modules not functioning together and also bring about the Blue Screen of Death for your system.

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

We’ve extended the assorted scenarios in mixing and equivalent various DRAM modules, and the potential pitdrops. Overall, the simplest solution is to prevent mixing DRAM altogether. Memory is very affordable these days, so it’s not essential to danger handling the hassle of incompatible modules.
