Solved!

DDR2 error 5 beeps

HP Recommended
HP Compaq DC7600 CMT
Microsoft Windows 10 (32-bit)

Hi there,

I've inherited this desktop system, working fine but just a bit slow. Installed memory is 2x1 gb ddr2/553mhz and 1x2Gb ddr2/800Mhz.

I've tried to upgrade with 2x4gb ddr2/800mHz but the system won't start, just repeats 5 short beeps.

Apparently, something's wrong with the memory.

Any help would be more than welcome!

Hi:

 

There is nothing wrong with the memory.

 

The max memory your PC can take is 4 x 1 GB of DDR2 memory.  DDR2-800 memory will run at a max speed of 667 MHz.

 

Some folks have installed 2 x 2 GB of DDR2 memory in there, but a 4 GB memory module definitely will never work.

 

See the dc7600 quickspecs below...the memory upgrade info can be found on page 7.

You're very welcome.

 

You stay safe and healthy too!

 

Hopefully, you will be able to get vaccinated now, or very soon.
