Dell Inspiron N5110 RAM Upgrade

If you open Google and search for Dell Inspiron N5110 RAM upgrade, the first couple of search results point to support threads on the Dell community website. In one such help thread, a person from Dell support says that this laptop doesn’t support a 1600 MHz memory module. Let’s see if it is actually true.

In the setup guide for this laptop, it says the memory type supported is 1333 MHz SODIMM DDR3. See Figure 1. Also, note that the maximum memory supported by this laptop is 8 GB.

Now, the question is what happens if you use a 1600 MHz DDR3 memory module with this laptop? I tried it. I tried a Samsung 4 GB 1600 MHz memory module in my Dell Inspiron N5110 laptop. It has got an Intel i3 series processor.

As you can see in Figure 2, the BIOS utility shows the Memory Speed as 1333 MHz. So, this laptop’s motherboard will run a 1600 MHz DDR3 memory module at 1333 MHz speed.

If you use two memory modules, one that runs at higher speed, say 1600 MHz, and the other that runs at a lower speed, say 1333 MHz, then the motherboard will run both memory modules at the lowest speed of the two, which in our examples is going to be 1333 MHz.

I had to upgrade RAM of my Dell Inspiron N5110 laptop because 4 GB was not enough. I inserted two memory modules in the sockets of my laptop. One memory module was Samsung 4 GB 1600 MHz PC3L-12800S (see Figure 3), and the other was SK Hynix 4 GB 1333 MHz PC3-10600S (see Figure 4). The BIOS showed total memory as 8 GB and memory speed as 1333 MHz (see Figure 5).

Did this become a Dual-Channel configuration? Yes, I checked in CPU-Z (see Figure 6). The motherboard supports the above two given memory modules in a dual-channel configuration.

Does more RAM means higher performance?

Generally, having more RAM would not result in higher performance. If you want to see a noticeable increase in the performance of your laptop, then you need to use Solid State Drive (SSD) instead of mechanical Hard Disk Drive (HDD). You need more RAM when you want to

  • Open a lot of tabs in your web browser
  • Open a lot of programs simultaneously
  • Run heavy games or graphics editing programs

Conclusion

You can use a 1600 MHz DDR3 memory module with a Dell Inspiron N5110 laptop. But the laptop’s motherboard will run this memory module at 1333 MHz speed. The laptop motherboard supports a maximum of 8 GB of memory. Though, some people have reported that they were able to use 16 GB memory with this laptop.

Is there anything I missed? Or do you have something else to contribute? Let me know in the comments. Thanks!

  1. Nope, actually N5110 supports 16GB memory too. It depends on the CPU, install 2670QM Core i7 then 16GB (8×2) 1333MHz works on N5110. And I really recommend to do that because it drastically decreases the pressure on CPU and HDD/SSD under stress.
    For example having a Visual Studio open in debug mode and a VSCode building nodejs modules is enough to take 7GB RAM completely and behind that border Windows starts to consume virtual memory which is very slow on SSD (it was on a PC system guess what happens on N5110).

    With 16GB dell official PC doctor CPU and memory tests don’t make the CPU to overclock (though CPU still overclocks under the real process tensions and we don’t have any voltage problem in the HWInfo stats). BUT all of this depends on the BIOS version too. Dell has a very good support and they released A11 BIOS update in 2020, though the last ASUS N55SL Core i7 BIOS update was 2014 though both of this laptops support 16GB 1333 RAM.
    Actually it’s been said that N5110 supports 1600MHz but it doesn’t have a lot of difference on CAS latency.
    If you go to the merket (to test when you buy) some repairmen may say us the 1600 needs more power and a need of a third party update on n5110 power firmware, actually it’s a nonsense.

  2. Thank you so much for explaining it so profusely and simply.
    My only question is, you had in your Dell Inspiron N5110 already a 4GB DDR3 1333 MHz RAM, so if you add a 8GB DDR3 1600MHz RAM, will the laptop work at 12 GB DDR3 1333 MHz RAM?

    Thanks.

    1. If we look at figure 1, we see the manufacturer of this laptop has also listed possible memory configurations of 2 GB, 3 GB, 4 GB, 6 GB, and 8 GB.

      It doesn’t lists 12 GB. So according to the manufacturer, this laptop doesn’t supports 12 GB RAM.

      You can try inserting a single 8 GB memory module, and see if the laptop turns on.

      If it does, insert the second module of 4 GB capacity and see if the motherboard supports 12 GB RAM.
