Windows 10: Can I mix Ram Sizes?

Not sure if its just me but I see a lot of websites with inconsistent not very clear information. So I thought I'd ask my friends at 10 forums.

Can I have varying sizes ram on my mother?

From what my research tells me, yes, but it needs to be the same DDR and same speed so 1066MHz in my case.

Could I get some confirmation on this please.

Thank you =]

RAM

Hi,

there is no best brand, several brans are practically equal. Personally I prefer Kingston Value RAM.

Mixing two brands with identical parameters (not only size) is not a problem.

Mixing memory with different parameters (even of same brand) may cause some problems.

Check motherboard compatibility list before buying RAM.

 

Ram mixing

Ram Mixing is possible by these factors:

1. Voltage and frequency must be same as the other ram.

2. Ram mixing can be only done if you have ram values multiplied by 2(eg. 2gb and 4gb, 4gb and 8gb)

3. the type of ram must have the same DDR value and DIMM type





As you can see its running both 2gb and 4gb ram at the same speed on a 2 slot motherboard!

No drivers, No Anything needed. Just add your ram and done!

Just be careful of what factors that is needed to mix ram, because it can affect the motherboard itself.

Have a great day!

 

Issues with total memory size of dedicated available RAM

Hello Gevorg,

Thank you for posting your concern in Microsoft Community an we regret for the inconvenience.

From the description provided, I understand that the motherboard you are using has 4 DIMM slots which supports up to 8 GB of dedicated RAM.

To be able to understand the issue better. let us know how are you viewing the total memory size of dedicated available RAM in your PC.

Now, in one case, if you are using more than one module of RAM, and the frequencies at which they operate are not the same. There will be two outcomes:

• The modules will conflict in terms of DIMM frequencies and it will declare memory failure.
• Instead of downclocking one or more RAM/s, the motherboard will reject the ones from being accepted.

In order to ascertain if the hardware is correctly configured, I suggest you to check the system information in the BIOS settings. Refer to the manufacturer provided manual to know more about on how to access the BIOS settings.

In another scenario, your computer may also be allocating part of your RAM to other hardware modules, such as your network hardware.

As a secondary workout, I suggest you to increase the Virtual Memory and check if it helps. Follow the steps below.

• 
  Click Windows key + R to open the RUN command utility and type
  msconfig.exe, then press ENTER.
  
• 
  Click on Boot option and select advanced options.
  
• 
  Check the maximum memory box and change the value accordingly.
  
• 
  Click on Apply and Ok to save changes and click Restart the computer.
  

Hope the above information is helpful.

Thank You.
