Retrofitting laptop RAM?

My laptop has 16 GB of RAM, but due to video editing, this is a little bit small. There are 2 slots in total.

Question. If I take out the old RAM and replace it with two of the same new ones, will I still have problems? Does the new RAM have to have something in common with the old one when the old one comes out?
Question. Desktopram is the same as laptopram. So from the dimensions.
Question. When I have replaced the RAM bars, I have to change something. (Bios, or something)

1) If you put in the same RAM again, you will have the old problems again. There must be 32GB. Pay attention to the maximum RAM speed of your laptop.

2) Absolutely not. Colloquially one speaks of notebook / laptop RAM. I don't know the right name either.

3) No.

Just has to be the same version. So you can't pack a DDR4 RAM in a DDR3 board and vice versa. But you can take any SODIMM, it doesn't have to be a specific brand.
No, the dimensions are different (e.g. 204 pin SODIMM DDR3 vs. 240 DIMM DDR3)
No.

It depends on the total size the notebook can manage. Some are already at 8GB at the end, others at 16 and still others also manage the 32. You have to research that with the manufacturer beforehand about the model
NO. Desktop is DIMM and Notebook is SO-DIMM. Differ in size
NO, you don't have to do anything anymore. THAT is actually PnP

If I take out the old RAM and replace it with two of the same new ones, will I still have problems?

There will be no problems with the same RAM modules. However, if more RAM is built in than the mainboard can address, the computer will buckle. So inform in advance how much RAM is possible.

No!

Question. When I have replaced the RAM bars, I have to change something. (Bios, or something)

Usually nothing needs to be set separately. With larger RAM modules, however, a BIOS / UEFI update may be required. With my older Lenovo ThinkPads, I also had to flash the BIOS first so that 16 GB of RAM was accepted from the board instead of the original 8 GB.

NO, you don't have to do anything anymore. THAT is actually PnP

Thats not really correct. Especially with older motherboards it can happen that you first have to upload a different BIOS / UEFI so that more RAM can be addressed. I've also had older desktop boards that only ran as it should after an update.

Regarding the last point: not entirely true. Especially with older boards it can happen that an update has to be installed first. My older ThinkPads now eat up 16 GB of RAM instead of the original 8 GB.

Yes, that's right. Depending on the laptop, a maximum of e.g. 2x8GB is possible.

Hi, thanks for the reply. If I buy 32 GB crucial Ram sodimm, which is DDR 4, then does that fit? My mainboard has 2 slots. Or do I have to see if the mainboard can manage 32 GB at all? My laptop is 1 year alo, an hp. If that fits, do I then buy DDR 4 RAM, let the laptop battery run out, install the RAM and turn it on again?

Yes, you have to see if each slot is designed for 16GB. Which laptop do you have then I can take a quick look and link it here.

You should also be able to change it with the battery in and charged. Which off, switch on, and then 32gb should be in the task manager.

Thank you for your great support. My model is HP Pavilion Laptop 15-cw1xxx. Is from 2020.

Supports a maximum of 16gb, i.e. 1x16gb or 2x8gb.

OK thank you!

The first thing you should find out is the maximum storage capacity your laptop can support. You would have to know the laptop model and which processor is used. So this information would have been helpful to be able to help you further. Then you have to pay attention to the RAM type (DDR3 / 4), the type (DIMM / SoDIMM) and the supported speed. SoDIMMs are normally used for laptops / notebooks. You don't have to set anything in the BIOS / UEFI for new memory.

Which laptop model do you have?
Which processor is in it?
What kind of RAM modules are used so far?

My model number is: HP Pavilion Laptop 15-cw1xxx.

With Ryzen 5 3500 U, so far I module with 16gb ddr 4 ram has been used.

Channel is single, and SoDIMM. A very helpful user told me a maximum of 16GB, but why two slots when only 16GB is possible? In addition, I have often read something online with a maximum of 32 gb

Sry one last question. I also did some research online and read something of a maximum of 32 gb several times. I have exactly the same laptop at home, if I take the RAM out of it and put it in mine, then I have 32 GB. But if the system can only handle 16 GB, will I cause problems? Really, really thanks!

Do you have the links to do forums or pages where that was. The HP specsheets are unfortunately very poor. It may be that I made a mistake.

If only 16gb are possible and you put in 2x16gb then the PC just won't start. But if a maximum of 32GB should be possible then that is as originally intended (i.e. Switch and switch on).

So, the processor supports up to 32GB DDR4-2400 dual channel RAM.

However, this can be limited by the BIOS / UEFI of an OEM manufacturer such as HP. But since 32GB dual channel RAM kits are also available for the laptop, 32GB could actually work.

After that you can use a 2x 16GB DDR4-2400 Dual Channel SoDIMM RAM Kit, which shouldn't be cheap. However, faster memories will probably only run as DDR4-2400 RAM. I don't know whether the BIOS / UEFI of your laptop supports XMP for overclocking the RAM.

So the PC just won't start but nothing breaks?

Many thanks! If the RAM is faster, will it work, but only as 2400?

You're welcome. What could still be that you might have to update the BIOS for this.

Yes.
