Hello, and thank you in advance.

Today, I installed an 8 gb 3200 MHz ram together with a 4gb 2666 MHz ram. I read somewhere that this is fine since the higher ram will just clock down. Now, when I booted it with the 12 gb ram, it fails to boot normally and loops in "Automatic Repair couldn't repair your PC". So, I immediately put the 2 4 gb 2666 Mhz ram but it still couldn't boot and stuck with the same problem.

I also tried reseating the ram with all possible combinations (with and without the 8 gb 3200 Mhz Ram). But no luck. I don't have an xmp settings in my bios.

Any ideas?

System:
I have an Acer nitro 5 AN515-54-56VR.
i5- 9300H
2x4 gb dd4 2666 mhz ram CL19
128 ssd / 1tb hdd
Windows 11 (latest updates)

Ram:
Acer 8gb 1R*8 PC4 3200 CL22

Update your post to include full system hardware specs and OS information.

Go to Acer's website and download the applicable User Guide/Manual for your Nitro.

I found this link:

https://www.acer.com/ac/en/AE/content/model/NH.Q59EM.04Q

(Do verify that that link is correct for your Nitro.)

Reference the User Guide/Manual along with any Acer Forums or FAQ's to verify that you have indeed installed supported RAM and in a supported configuration.

Where did you purchase or otherwise obtain the RAM?

Hello and thank you for the reply. I've purchased the ram on an acer retail store. This new ram specs are:
8gb 1R*8 PC4 3200 CL22

Yeah the link you gave is right. The ram installed in my laptop is a CL19 and the new one is CL 22. do you think the ram timing got messed up when I tried to put the 2 together?

Are your sure that that was a real Acer store? Link? Just because "acer" may appear in the URL does not mean that the site is truly Acer.

The next step is to verify that your Nitro does indeed support the new RAM. You will need to dig into the specs to be sure. Both motherboard and RAM.

Another way to check if the purchased RAM is compatible is to visit the various RAM manufacturers and search for RAM options that match your Nitro.

For example (not a recommendation or endorsement):

https://www.kingston.com/en/memory/search

I made a quick search but did not note any RAM that matched your Nitro. Could be that my search criteria was incorrect.

You can search Kingston but also other manufacturers as well. Look for some consensus on supported RAM, specs, and installation configurations.

= = = =

After that you will need to review how the new RAM was installed.

What you did and how you did it.

Start with Acer:

https://community.acer.com/en/discussion/650530/i-want-to-upgrade-my-storage-in-the-acer-nitro-5-an515-54

However you can find third party tutorials as well.

For example:

https://www.windowscentral.com/how-upgrade-ram-your-acer-nitro-5

That windows central link may or may not be fully applicable so I recommend looking for similar links and comparing the instructions.

However, be very cautious because some links may be incomplete, have errors, be out of date, or just be completely wrong in one way or another.

Yes, I bought it in an Acer shop in a mall. I checked the bios first when I installed the new ram it reads 12gb (8+4). After that I can't boot to windows anymore. So I went back and remove that 8 gb 3200 ram. Return my 2 old 4gb 2666 ram and restore the bios settings to its default configuration. But, the problem (can't boot to windows) still persists.

EDITED

"But, the problem (can't boot to my desktop) still persists. " [My underline.]

Typo? did you mean laptop?

= = = =

Also found Crucial's website:

https://www.crucial.com/compatible-upgrade-for/acer/nitro-5-an515-54-(intel)

Do the listed RAM specs match the RAM that you purchased?
Yeah sorry about that. My laptop can't boot normally and windows can't diagnose the problem.

Sadly, No. It didn't matched up. I forgot to double check all specs of the ram and directly installed it to my laptop.

Crucial recommends a:
DDR4 2666 - CL19 - 2R*8

Old ram:
DDR4 2666 - CL19 -

The one I bought:
DDR4 3600 - CL22 - 1R*8

Unfortunately, getting the RAM specs all matching, etc. can be problematic. Many factors involved and sometimes the information is not as clear and reliable as it should be...

Just FYI:

https://www.cgdirector.com/can-you-mix-ram-brands-memory-modules/

= = = =

Are you able to return the purchased RAM to the Acer store?

Take the RAM specs with you (for laptop and the RAM sticks you have) and have the store help find the correct match for the laptop and existing RAM modules.

If possible take the laptop with you. That way you can test on-site to ensure that the laptop will indeed boot and work with what ever RAM and/or RAM combination needs to be installed.

Hopefully the Acer store is professional and proficient enough to help do that....

I see, I'll do that as soon as I can. My question is, is there a way to fix the issue of my laptop not booting up even though I returned my old ram back?
