Operating System: Microsoft Windows Vista (64-bit)
Hello... I've got an old HP xw6200 desktop computer with Windows Vista installed and 3 sticks of RAM memory, each having 1 GB. Problem is... it uses only 2 GBs out of those 3... and that's because having 3 sticks of RAM is not a valid configuration. It works only with 1, 2 (1 pair) or 4 (2 pairs) - the 3rd one is seen by the BIOS and the OS, but is not used.
So... I decided to buy another stick... an (apparently) identical one. When I insert it and turn it on, I hear 5 beeps and the system is not working or booting. The one from the lower part of the image (the 'IBM' labeled one) is what works... so it's one of those that are installed in 3 pieces. The one from above is what I bought and wished to provide as an upgrade. Apparently, the only difference is the 'eco' label. The machine simply rejects it... 5 beeps and no boot. I tried leaving it with two of the good ones and the BIOS and OS both see it but, as in the previous case, it isn't used.
So my question is... is it a suitable RAM module and should have worked with those other three (but is defect/broken or something like that) or it isn't compatible with this computer at all? I also cannot find any RAM settings in the BIOS.
Unfortunately, mixing memory modules that are not exactly alike rarely works.
The modules need to be:
Of identical manufacturer, capacity, bandwidth, and type ( 1-sided or 2-sided) and in the proper slots.
A smart way to upgrade is to purchase from a memory manufacturer that guarantees compatibility with your desktop PC. I suggest Crucial.com as a good source for these. The downside in your case is that PC is old.The memory is no manufactured by Crucial.
