ACER ASPIRE XC 603 adding RAL

Terwaan · August 2017

Hello,

I want to add an additional 4GB DDR3 RAM to my ACER ASPIRE XC 603.
Question: where do I connect it to the motherboard?

Hi,

When you open the side panel, you can view the slots by the side of CPU fan.

Thanks, are all brands of DDR3 4GB RAM compatible with the original installed 4GB DDR3 RAM?

Hi,

You need to get DDR3L, 1333MHz type SODIMM RAM, you can install CPU-z and find the exact specs of your current memory, get the matching RAM.

These are the part numbers, you need only one module.

OK, It seems that the original and the to be added memory can't communicate.

The original is a KINGSTON 4GB 1Rx8 PC3L-12800S-11-12-B3

The new memory is a 2-Power: MEM5103A.
The 2-power is a dual-rank. I think the Kingston is a single rank. Is that the cause of the problem?
If so, do I need to buy an additional 2-power dual rank or do I need to replace the 2-power by a single-rank RAM?

Best

Hi,

Did you buy the memory module quoting the part numbers I posted? I think many people have problem in upgrading with memory upgrades using any other matching modules with same specs( eg: Crucial or other brands).

I would suggest you to buy memory module especially made for Acer, like in my links below.
