DDR2 error 5 beeps

[Profk99]

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.

Thanks for the reply! I suppose I'll have to work with the old configuration! Thanks again and stay safe & healthy!

You're very welcome.

You stay safe and healthy too!

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