Inquiry on Upgrading Laptop RAM: Compatibility and Configuration

[SR_5521]

I'm planning to upgrade my laptop's RAM to 16 GB, and currently, I have 4 GB on my HP 250 G7 Notebook PC. The processor is an Intel® Core™ i3-1005G1 CPU @ 1.20GHz. Could you guide me on the recommended RAM speed (in MHz) that is compatible with my laptop? Additionally, I'm considering adding an 8 GB RAM stick to the second slot while keeping my existing 4 GB RAM in the first slot. Would there be any issues with having unequal RAM sizes, such as 4 GB and 8 GB? Furthermore, is it okay if one RAM stick has a higher Megahertz frequency than the other, creating an uneven frequency?

Spoiler

One Last Query is that can I upgrade my Laptop Processor because it is too laggy.

The processor is an integral part of the motherboard and cannot be upgraded.

You can install 2 x 8 GB of DDR4-2666 MHz memory in your notebook.

If you want to install DDR4-3200 MHz memory that will be fine as long as the memory is 1Rx8 and CL22.

It will automatically bridge to 2666 MHz because that is as fast as your notebook's processor can run the memory at.

You can leave the 4 GB memory chip installed and add an 8 GB memory chip and have 12 GB in total.

However, the memory will still run in single channel mode.

In order for the memory to run in dual channel mode, matching memory capacities must be installed in both slots.

Below is the link to the service manual:

The simple way to do this is to upgrade to a pair of identical guaranteed compatible memory modules. see the link for guaranteed compatible memory and SSD upgrades.

Your Core i3 processor is integrated into the chipset. That means that it is soldered on and not upgradeable.

Your other questions"

"Additionally, I'm considering adding an 8 GB RAM stick to the second slot while keeping my existing 4 GB RAM in the first slot"

That is a non-standard and sometimes failing upgrade path. You may only see one of the installed memory modules recognized by the OS and BIOS. I would not risk going that route.

"Furthermore, is it okay if one RAM stick has a higher Megahertz frequency than the other, creating an uneven frequency"

Not really. The modules will default to the lower frequency. That is still not the best plan for an upgrade.

Can you tell me in my HP 250 G7 NoteBook PC can I upgrade to SSD. If yes then what type of SSD can I use. Can I use M.2 (NVMe) SSD.

[Paul_Tikkanen]

Yes, your notebook has a M.2 slot that supports NVMe SSD's.

The slot is PCIe Gen 3.0, so if you buy a PCIe Gen 4.0 SSD it will not run at its maximum advertised read/write speeds.

This chart provides the maximum transfer speeds from the various PCIe generations:
