Additional RAM not detected in BIOS

Jump to solution

Hi,

I have Dell Inspiron 15R n5110. I already have RAM of 4GB installed.

I wanted to upgrade it to 8GB so I bought another 4GB stick to put in the 2nd slot.

But the BIOS is not detecting the new stick. I checked on Speccy software and it is showing 8GB RAM with both slots utilized, but BIOS is not detecting the additional RAM and is still showing 4GB.

I ran the diagnostics from F12 and it showed no error.

Can anyone please suggest how I can activate the second RAM stick too? Or if there might be an issue?

P.S. - The new stick configuration is exactly similar to the one already in use.

 

Thanks!

Best regards,

Sanchit

Run the Dell diagnostics on the memory (F12 at powerup). Try one module at a time -- if the new module works in the first slot, but neither module works in the second, be sure the contacts are clean.

If they are, and both modules check out - the second slot is bad.

Hi all,

I have finally found a solution and it is working now. Both RAMs are now detected by BIOS and total 8GB is being used as per the Task Manager.

Steps:

  1. Check each RAM stick individually in all slots.
  2. If all slots and RAM sticks are working, put all RAM sticks in slots, and run F12 diagnostics just for Memory.
  3. It took around 1.5 - 2 hrs for me.
  4. System will restart automatically after successful test.
  5. Now the total RAM should be visible in BIOS.

Thanks @ejn63 and @inspiron 3593 for the suggestions!

Best regards,

Sanchit

Hi,

I ran the diagnostics with a thorough test for the below scenarios:

  • Old RAM stick in Slot 1 - Test passed 
  • Old RAM stick in Slot 2 - Test passed
  • New RAM stick in Slot 1 - Test passed
  • New RAM stick in Slot 2 - Test passed
  • Both sticks in Slots 1 and 2 - Test passed

Now I am not sure what to do next. Still my BIOS is picking only 4GB.
Any suggestions what I can do next?

 

Thanks,

Best regards,

Sanchit

Since the system does see the RAM, but doesn't use it, contact your memory seller to determine compatibility with your system.

1.Which Ram brand you are using ? (Ex: Adata , Kingston , Samsung , Micron , ............).  Did you try Kingston KCP or KVR ram brand?  

2. Try this way go to start then click on windows administrative tools then click on windows memory diagnostic and run the system. then finally it'll show the errors of the system. if not show any error message then problem is in your hardware side. 

3. reset the cmos battery ( follow the link :  https://www.dell.com/support/article/en-us/sln292953/how-to-troubleshoot-dell-laptop-battery-issues?...)

4. check the ram speed and specification (new ram and old ram).

5. try to install the windows 10 with your new ram and after that install the old ram and check.

6. wipe the hdd data properly (may be any software crash) and install the windows 10 again.

7. check the new ram any physical damage. 

8. make sure your laptop are clean (ram slot , and other slots).

9. final step : remove your old ram and work with your new ram for  slot 1 and slot 2 (buy the same new ram) and check whether the system is work or not. may be old ram can't be support with new ram for work.
