Hi, I am looking to purchase more RAM but I need some help concerning compatability issues that may occur.
I will post my system specs below so that once you have read my problem you can go back and see them.
Microsoft Windows XP Professional (5.1, Build 2600) 32 bit
System Manufacturer: Compaq Presario 061
System Model: EP150AA-ABU (SR1729UK) GB610
Processor: Intel(R) Pentium(R) D CPU 2.80GHz (2 CPUs)
Graphics Card: NVIDIA GeForce 8400 GS 512.0 MB
Memory: (This is the part I need help with) 1022 MB RAM
DDR2 PC2-4200U 512MB x2 sticks
I have 4 slots altogether
I did a scan online for my computer SR1729UK and it told me this:
Each slot can hold up to 1GB.
I also did some research, I was told from several sources that my Operating System, being 32 bit, can only make use of up to 3GB ram so having 4 would be useless.
The online scan also showed that recommended RAM for my PC would be DDR2 PC2-5300.
I have searched online and also visited my local PC World and found these sticks without any trouble so I am ready to buy them.
I want to have 3GB of RAM as having 4 is useless as my OS would not use 4 so would it be possible to keep 2 slots occupied by my current 512MB DDR2 PC2-4200U sticks and the two other slots occupied by DDR2 PC2-5300 1GB sticks.
Would this be compatible, bearing in mind that the brand who manufactures the 5300's is different from the brand who manufactured the 4200U's current sticks.
Or, would it be better to just buy 3 DDR2 PC2-5300 1GB sticks and have all of the sticks the exact same, would there be any less power, any trouble or effects if did the first option.
