FAQ about Acer Aspire 5503 RAM
What kind of memory does the Acer 5503 take?
It uses DDR2 SODIMM modules - the laptop-sized memory sticks. Make sure you get DDR2, not DDR3 or DDR4, they won't fit or work.
How much RAM can I put in the Acer 5503?
Maximum is 2GB total. It has 2 slots, so you can do 2x1GB sticks. Don't bother trying to install more - the system won't recognize anything above 2GB.
What speed RAM should I get for the 5503?
Get 533MHz (PC2-4200) modules. Faster RAM will work but it'll just run at 533MHz anyway, so no point spending extra on faster sticks.
Can I mix different RAM sizes in the two slots?
Yeah, you can do something like 1GB + 512MB if you want. Just remember the total can't exceed 2GB. Matching pairs are ideal for dual-channel performance but mixing works fine.
Do I need to remove the old RAM when upgrading?
Depends what's already in there. If you've got 2x512MB and want 2GB total, you'll need to replace both with 1GB sticks. Check what you have first before ordering.
