Yes, you can .

Many notebooks have combination 2 GB stick + 1 GB stick.

 

thanks for replying ,,,, but u know whats my problem ,, i am traveling saw i am not my country>> i am in egypt ,, and here they are a little bit what can i say ,,, they dont know enough about notbooks , and they said to me there will be problems in the pc , u must have the same ram in each slot ,,,

then i will upgrade it (2gb in a slot ,,, and 512 in another slot ,,,

great ,,,,

thanks bro

 

Memory sticks can be from different manufacturers, different size and different speed. Speed will be set up to work as the slowest one.

But there is still a problem. Motherboard of Aspire 5570 supports up to 2 GB RAM.

 

the 5570Z has 2GB limit but not the 5570. It will take 2GB per slot, though only show you around 3.3GB usable.

 

i cheked that ,, it can be upgraded untill 4 gb ,,,,,, but i didnt understand what u mean that (Speed will be set up to work as the slowest one. )

 

if your 512mb stick is 533mhzand you buy 2gb stick 667mhz, you loose the speed of your 2gb stick, i.e. the whole ram will be at 533mhz

 

Yes, you have right . I messed 5570Z and 5570.

In my search for information, this is the closest I found to what I am looking for; however, before I place my order for additional ram, I need some assistance.

1. My wireless keeps giving me "limited or no connectivity" messages. I have deduced that it may be an issue with the operating ram. I currently have 2 512MB of DDR2 533 MHz.

2. The information in my manual says

System memory
- Up to 2 GB of DDR2 533/667 MHz system memory, upgradeable to 4 GB using two soDIMM memory (dual-channel support)
- 256/512 MB of DDR2 533 MHz memory, upgradeable to 2 GB using two soDIMM modules (dual-channel support) (for TravelMate 2480)

Specific information
OS: MS Windows XP Edition
Processor : Intel(r) Celeron(r) M CPU 410 @...
Chipset: Intel(r) 955XM/945GM/PM/GMS/940GML
Harddrive: HTS421240H9A100.37.26GB

My question is: Can I upgrade to 4 GB of DDR2 667 MHz only (totally bypassing the 533 limitation that I currently have) or am I limited to 2 GB of DDR2 533 MHz for my particular laptop?
