Memory type for the acer am5630-u5209a

considering that acer is made currently over 200 different motherboards accepting several different types of ram - WHICH MOTHERBOARD?!?

if you want an answer - you need to state correct question, telepathy is grossly overrated... in general - if your motherboard is running win7 and have free slots - it should accept 4gb ram.

to check and be sure go to the acer site, find your motherboard and check specifications for it, then you will know what and how much of memory your motherboard will accept.

I am not seeing any motherboards at the normal places I would look. How old is this computer? If it is less than a year, call Acer Tech support and they should repair it at no charge. As for sound card, it is built into the motherboard. If you have a PCI slot left open you could add a seperate sound card.

Hope this helps

The e RAM specifications for your Acer are -
Memory - DDR 266/333/400 expandable up to 2GB

According to the manufacturers specs these are the memory specifications you need, and the maximum the motherboard will accept...

3 x 168-Pin DIMM-socket
for up to 768 MB memory SDRAM
with 8, 16, 32, 64, 128 and 256 MB size

the upgrading can be done only if the motherboard support if your laptop had sata provision you can use them if you dont have you cant use sata check the motherboard

Surely to load XP is a DownGrade. As this notebook is dual core, I would run Vista 64 or better still Windows 7 64.
If you wish to persist with an old system, you require SP3 for XP.That may be available from a software store but is no longer supported by Windows.
Try http://www.notebook-driver.com/laptops-information/acer-aspire-4520-notebook-technical-specifications/ for drivers that you will require to have support from Acer.

Hope that clarifies your situation.

go to acer support find your machine and operating system then download the drivers you can also do a BIOS update however be very careful doing a BIOS update you can render your pc completely useless and will be un-fixable

Pointers are variables which store memory address of other variables.
It is denoted by an astrix *
Pointers and normal variables must have same data types.
Need of Pointers:
As said pointers variables store memory addresses of other variables, this can be used when we want to perform some calculations on a variable, we pass the address of this variable to the function from using pointers, thus any changes made to the variable will directly affect the variable as it is pointed to the same memory location.
It can also be for pointing various memory locations e.g. video memory. In the days of Dos we could actually read and write directly on to the video memory using address 0xB8000000 hexa decimal address.
Declaring a pointer:
int a = 10;
int *p = &a;
Here are passing address of a to p. Make sure that the data types should be same.
When we use pointers as arrays, it is much faster then the usual array iterators.
int num[] = {43,52,54,53};
int i=0, *j;
j=&num[0];
while(i<=3) { cout<<"num ["<<i<<"] = "<<*j<<endl; j++; } // This peice of code is faster than following method
for (int i=0;i<=3;++) { cout<<"num ["<<i<<"] = "<<num[i]<<endl; }
As we are directly working on memory.
Pointers are most commonly used to allocate memory dynamically, using new operator.
int *p = new [10];
This code allocates for 10 integer type array dynamically.
Dont forget to release the reserved memory using new operator by delete operator.
delete []p; // Frees the reserved memory.
This is an overview of pointers, as it requires study and practice.
Please rate. Thanks :)
