3 beeps then 2 beeps after new ram

HP Recommended
Omen 870-224
Microsoft Windows 10 (64-bit)

I installed new ram then it started beeping 3 times then 2 and won’t start up,   I moved the old ram over to the other slot to see if it was bad and got the same thing, so I moved the old ram to the first slot and it’s still beeping,   I’ve tried to rest to board by taking the battery out, any More opinions?

Did you have the power cord attached while you were doing this?

Depending on the age of the PC and the BIOS vendor...



I would remove all RAM.

Do a hard reset, and run an F2 diagnostic on the RAM.


Then repeat with the original RAM and compare results.


Then swap the old for the new and repeat, analyse the 3 results and post any anomalies or conclusions.


First:- Turn off the computer, press and hold the PWR button for 4 seconds.

Then - Leave only keyboard and mouse connected, disconnect all externally connected
devices such as Docking Station, USB storage devices, displays, and printers.
Unplug the AC adapter from the computer.

Next - Press and Hold the Power button for 15 seconds to Hard Reset.
Rinse and Repeat; Re-Connect the AC adapter.

NOW begin checking/testing/proving the Hardware is fit for purpose.
Power on your PC, press ESC (repeatedly), then F2 at the prompt.
Choose System Tests (Fast Test does a 4 minute hardware check).

The BIOS does need to acknowledge the RAM changes and just swapping without allowing time for a re-acquisition may be the problem. So go into the BIOS and view the results of any amendments.
