Can I have too much Ram in my Laptop?
In reality, the motherboard would likely recognise a lower amount of memory than you are aiming for, as it may misread the unexpected memory module as either not being there or as having a smaller capacity than it really does. This can even result in a system failure that will leave your laptop unable to even boot up until you remove the upgrade.
For example, if you had two SoDimm slots for RAM with two 4Gb sticks in them (making a total of 8Gb) and your motherboard supports up to 8Gb, then exceeding it will achieve...well, not much. If you were to replace the two 4Gb sticks of memory with 2 x 8Gb sticks, then your laptop will likely either not turn on at all or it will only recognise one of the sticks, meaning you still have 8Gb total!
Ask an IT professional about exceeding recommended RAM memory specs and they will tell you that it shouldn’t be done, as all, it does it cause problems. You’re essentially plugging in something the computer cannot correctly recognise (as it’s not programmed to do so), so you can’t expect the hardware to be compatible, even if it seems like it ‘should’ work.
There is another fundamental reason that you won’t achieve higher capacity by exceeding the recommended limit and that is that the BIOS and the operating system are designed to see the lower amount, so will only recognise that amount, regardless of how much is placed in the slot.
NecessityIf you are in the position that you are struggling for parts for your laptop and you need to use modules that are too large for your motherboard, then this is the only occasion that trying it might be a good idea. There is a chance it could work for you and there is likely to be no damage caused by trying.
If you want our advice, then we would recommend not installing more than your laptop is recommended to support, as it’s just not worth the effort. If you have no other choice then it might be worth trying, as it may recognise at least some of the installed memory upgrade.
