RAM upgrade issue. Black screen

[nick46]

I installed a second 4GB stick in this machine I get a black screen. The RAM was purchased from crucial and is defintely correct.

When I swapped out the original memory for the new module the machine did boot but seemed to get stuck in a repair loop during the boot sequence. When I replaced the original memory the machine booted fine.

I tried the new memory module in another compatible machine and I get a similar problem i.e. stuck on boot, which suggest it is perhaps faulty.

Returning to the HP machine I tried several other compatible modules which I know are healthy however I still get a black screen i.e. the PC doesn't turn on.

Any thoughts/suggestion will most welcome.

Thanks!

Thank you for being a part of HP Forums, 

It'll be an honor to guide you through the steps needed to identify your concern and/or address your query.

When it comes to memory modules, things may get a bit complicated if the right size and type isn't used, 

hence its always recommended to check the HP service and maintenance guide: Click here for details. (refer to Page.2 of 19 under "Note about systems configured with 4 GB of memory").

That said, your device is only compatible with the below details:

• Dual channel memory architecture

• Two 204-pin DDR3L SODIMM sockets

• Supports DDR3L SODIMMs:

  • PC3L-12800 (1600 MHz)

  • PC3L-10600 (1333 MHz)

• Supports up to 4 GB on 32-bit* systems

• Supports up to 8 GB on 64-bit systems

   NOTE:

* - 32-bit systems cannot address a full 4.0 GB of memory

If you've not been using these details during the replacement/upgrade, please do it now and it should fix the issue,

However, if you've made sure the above is compatible as per the above information and yet the issue persists, I recommend you run a hardware test on the device using the Hardware diagnostic test - by tapping on F2 key during the restart of the PC, and get back to us with the results of the test.

Let me know how that pans out

I will have a colleague follow-up on this to ensure it's taken care off,

As I need to know if the issue has been resolved, to get proper sleep at night.
