HP Z240 Desktop

HP Recommended
Z240
Microsoft Windows 10 (64-bit)

Hello, I have an HP Z240 desktop I replaced the system board. Upon bootup I get a series of 3 beeps followed by 2 and it repeats 5 times, after that the power button just blinks red, cannot seem to find issue.

 

Thanks in advance.

you most likely have a ram/memory issue

 

recheck that you have the correct ram, and that it is installed in the correct memory slots Unbuƫered ECC or non ECC DIMMS only Do not intermix DIMMs of diƫerent technologies.

 

ECC Unbuƫered DIMMs (UDIMMs), Registered DIMMs
(RDIMMs), and Load Reduced DIMMs (LRDIMMs) are supported on your workstation

 

please read the z240 service manual (page 53)
