How To Check If I Have Free Ram Slot
Upgradeable recommends the CPU-Z scanner tool to identify what type of RAM your computer uses and how many slots there are available. |
Here is the quick guide to identify your ram, the number of slots and how much it will cost. |

Tips for a compatible upgrade
Match new RAM to your existing ram speed. You do not get a speed increase mixing fast and slow ram, it always defaults to the slowest speed. There is a chance the new RAM will not be compatible. So there is no upside, and all downside - not a good bet.
Use the computer model information to search Upgradeable for your model. We do not charge more for brand specific RAM. Do not assume you can use 8GB or 16GB modules by default. Some models are limited to the amount of RAM it can use. If you are unsure internet search your model with 'max ram'. If your computer has 2 slots and the maximum RAM is 16GB then the biggest module you can use is 8GB. However if the maximum ram is 8GB then the largest module you can use is 4GB. This is number one reason for incompatible RAM.

When the DirectX Diagnostic Tool opens, click on Display 2; you should see the information about your discrete GPU. The VRAM you have can be found at Display Memory. We hope that this helps you to. See the brand of the memory modules name under the 'Manufacturer' column. Checking memory part number. To find out the part number of each memory module, use these steps.

Recently, I upgraded my laptop’s RAM from 8 GB to 16 GB and if you are on the same page wondering whether it is running in the dual-channel mode. Here is how to check it.
Foremost, check on the manufacturer’s website that your motherboard supports dual-channel memory. Next, it’s pretty straightforward and you require an app called CPU-Z. But before that, we will have to understand what is the dual-channel mode and how to ensure you install a RAM in dual-channel mode. If you are well aware of these concepts, you can move ahead to this portion.
Consider the channels as roads from your RAM to the CPU. When there is a single channel or a single road, the vehicles have to drive in a single line behind each other. Whereas in the case of dual-channel memory, 2 vehicles can drive simultaneously which leads to an increased number of vehicles or more data being sent.
Now, there is an intermediatory unit between the RAM and CPU known as the memory controller which guides the data to and fro.
Previously in the single-channel architecture, there was a single path to send data. So, the memory controller couldn’t route data simultaneously from 2 RAM sticks. This caused the CPU to wait and it is known as the bottleneck effect. Later, we doubled up this wired route which is known as dual-channel architecture (you also have triple and quad-channel, let’s leave it for this article). This enabled the controller to route data simultaneously from 2 RAM sticks to the CPU. Hence, the CPU has enough data to process every time and it doesn’t have to wait. This eliminates the bottleneck between the CPU and RAM.
So switching to dual-channel will let you better utilize your CPU with the only bargain being the increased RAM stick. To show the difference between single-channel and dual-channel, I did a benchmark with a single Crucial 8GB 2400 Mhz RAM and 2 x 4 GB 2400 Mhz RAM sticks. The results show that when in dual-channel mode (ie. 2 x 4 GB sticks), the read-write speeds are about 25-30% higher.

How to choose RAM for dual-channel mode
To begin with, I am using an Acer E5-575G laptop which uses SODIMM memory sticks. In simple words, DIMM is basically longer memory sticks for desktop motherboards whereas SODIMM is a smaller memory stick for notebooks. Here, I am using a SODIMM memory for my laptop which has 2-memory channels.
Laptops have only 2 memory slots so they are supposed to run in dual channel (if supported on the motherboard). Desktop motherboards, on the other hand, have 4 channels and even 6 to 8 channels, so you need to put the RAM sticks in channels that are similarly color-coded. For instance, in the below figure, the RAM channels are colored black and blue. So, if you insert the RAM sticks in the blue slots or black slots it would run in dual channel mode. In case you insert one of the stick in the black slot and the other one in the blue slot, it won’t run in dual channel mode.
With all the complexities aside, now let’s move down to RAM specs. There is a lot of confusion on RAM specs and what dual-channel requires, let’s discuss those.
Foremost, it’s advisable to buy RAM kits or the same RAM units. The reason being, the RAM needs to have the same Double Data Rate version (DDR), the same frequencies and the capacity to run at full potential. Having said that, there are some misconceptions about the dual-channel mode.
- If you have RAMs with different frequencies it won’t run in dual-channel mode.
Wrong! In case you have a 2400 Mhz RAM and 1800 Mhz RAM, it will run in dual-channel but will fall back to the lower 1800 Mhz frequency.
- Similarly, if you have an 8 GB RAM and a 4 GB RAM stick, it won’t run in dual-channel mode.
Wrong! This is called mismatched memory. However, due to modern-day CPUs, it will still run in dual-channel mode. The first 8 GB will run in dual-channel whereas the rest of the 4 GB will run in the single-channel. To know more about this, read about Intel’s Flex memory mode and flex mode even works on AMD CPU’s. Have a look, at the following screenshot.
However, if you have the budget and resources, it is advised to use a similar specification memory.
How to check dual-channel mode
The easiest way is by using a third-party app called CPU-Z. Download, install and open the app. The first page would provide you a summary of the CPU specifications. Move over to the Memory tab and in the first row you would see a labeled as “Channel #”.

This shows you the memory channel mode. In my case, I have a couple of 8 GB RAM sticks installed on my laptop. So, you can see the channel mode says “Dual”. In case, you have memory sticks running in single-channel mode, it would show up as “Single”

Additionally, you can also check the dual-channel mode through a benchmarking app like MaxxMem. Moreover, some manufacturers like the ASUS or the Acer predator show the memory channel mode in the BIOS menu itself.
For iMac, you can do so using the System Information inbuilt app. Navigate to the Memory tab and you would see memory slots. Count the number of Banks to determine the number of channels. In my case, we have Bank 0 and Bank 1 which means dual channel.
In the case of Linux, you can use the following command
