I still use successfully and satisfied my AMILO A7620 with an AMD Athlon XP-M processor. So far I had the original two RAM modules of 256M each.
I now wanted to upgrade to 2G RAM. I purchased a Kingston 1G RAM Module (the one that is indicated on the Kingston website for the A7620 with XP-M processor). Removing the two 256M modules and inserting one 1GM module in the lower slot works fine. The computer starts and works perfectly.
However, when I insert in the upper slot additionally a 256M module then the computer makes a short start up bip, makes a very short blue screen and then Windows XP starts up, but goes after that into the Blackscreen from where you can select in which mode you want to start Windows. Clicking on "Start Windows in normal mode" repeats the procedure and I finally have to switch off the Power. Removing the 256M module and keeping only the one 1G module then everything is OK again.
I thought it might be the combination and purchased a second 1G RAM module, but the same happens as described above.
Does anybody of you have had a similar experience and/or has successfully brought this to work? Please let me know.
I am not sure if one can test if the processor is REALLY the XP-M (even the stickers say so...), because according the specs only the XP-M version allows for 2G upgrade, the normal XP version only for 1G. Is there a possibility to verify this, any hints how to do that?
Or can it be the BIOS version (which I have difficulties to believe it could be the problem because the machine basically starts)?
Would be great to get some help from some of you. Thanks in advance.
