Solved: Upgrade RAM Probook 450 G4 - HP Support Community

alberto9491 · ‎03-09-2017

I recently purchased a Probook 450 G4 with 8 GB of RAM.
I purchased a module 8GB Kingston KCP421SD8 / 8 for the purpose of upgrade to 16GB.
I put it in place of the original, and works well.

But I can not put in the free slot neither the new nor the old module.

As seen from the picture, the two slots have different retaining tabs.
In the left one (factory occupied) engages easily.
In the right (free) does not fit in whole (as seen in the second image).

What should I do to fix it?

Thanks and regards.

That is your own choice. I do recommend that you use two absolutely identical memory modules.

The image you posted does indeed show that the format of the memory chips on the modules are decidely different.

If identical, the modules should run in dual channel mode and that is a plus. It allows for more efficient use of the modules, reducing a bottleneck.

Ii actually looks as if the module is not inserted correctly. There should not be any gold on the module pins visible if inserted properly. The left hand memory module is correctly inserted.

Have you tried putting the original module in the slot?

Is your notebook still in warranty?

Yes, I have.

Yes, it is in warranty. I bought it three month ago.

Should it enter in the slot easily?

Memory modules always fit in relatively easily.

Gently press in from the top of the module and then gently press it down to click it in place.

There should be no gold visible from the pins on the bottom of the module.

I was able to let it in, making a more strength.
At the start, this happened:
1) with the old module in the factory location and in the new in the free: the system as not started by doing beep, beep...
2) with the new module in the factory location and the old in the free: it has sent a message for a change in memory size from the last startup and then everithing was right.

Do you know why there was a beep, beep...

When upgrading installed memory in a PC, it is a best practice to install a pair of absolutely identical memory modules.

Since the modules you have in place are different capacities, the notebook's BIOS has an issue with that.

That is why you got the error beeps.

You are fortunate that the notebook still boots up to Windows.

Most people are not that lucky.

Kudos are appreciated.

Marking my last post as the solution will help somene who has the same notebook as yours not have the same problem you did when upgrading their notebook's memory.

Can I leave the things like that or it is better to replace a memory with a alike ?

Anyway, the two memories has the same capacity (but different brand): 8 GB.

Is it wise to upgrade HP ProBook 450 G4's memory from 8GB to 16GB? Isn't 8GB enough?

erico · ‎04-25-2017

8GB should be enough.

I would think that16GB is overkill, unless you are editing video or doing something else that has a similar memory requirement.
