upgrading ram on old compaq nx9005

ok, I will have two modules from ASUS (2x512) and I would like to ask you guys if I can add them into my old HP compaq nx9005. the thing is that the old nx9005 only supports DDR PC2300 and PC2700 (as I found out... www.crucial.com) but the moduls that are in the Asus are probably DDR2 PC2-4200 or PC2-5300..... are these completely different or can I put them into the old hp? I have no other use for them so I would rather use them than to leave them in my drawer...thank you

 

you can't use them

 

The slots on the bottom of the DDR and DDR2 sticks are in different locations, if I recall correctly - as a result the sticks are incompatible and not interchangeable. Even if they did fit, the way the memory works would not function correctly with the motherboard. If you want to upgrade your RAM in the Compaq, you'll have to buy new DDR.

 

thanks guy....i actually dont wanna upgrade, its just that due to some changing in other laptops, ill have 2x512 free and I was wondering if I could use them somewhere....thanks a lot for the advice... rep given

 

one more thought....would the RAM modules fit into a PC by any chance? or do desktops have completelly different locks too.... thanks

 

Desktops usually have full size DIMM's while notebooks use half size SODIMM and also have different pin configurations, so notebook RAM wont fit into the desktops unless that desktop uses SODIMM's(SFF's like Mac mini etc)
