1. How did you find 528 MB stick of RAM ? Did you think 512 MB?

I want to upgrade it to : 1x528mb+1x2gb

Well....there won`t be TOO MUCH difference between 2 GB and 2.5 GB of RAM, and the 2 GB stick will run at the 512 MB stick speed, so you may actually LOSE performance. So, I suggest getting 2x1 GB stick of RAM (identical), where you`ll benefit the Dual Channel Technology (if your motherboard supports it).

NOTE: Make sure the sticks are supported by the motherboard.

Google is your friend

Where are you getting that figure from?
There's no such thing as 528mb memory modules.
Thery're 64, 128, 256, 512, 1,024 mb (1gb) etc. on modern computers
The amount of ram you have installed in the mboard is shown as the Physical memory amount in System Information.
(Start - Run - type: msinfo32 , click on OK or press Enter - look on the right side.)
Some bioses subtract the amount of ram that's shared with the onboard video - the video built into the mboard - from the total amount of ram installed, and that may also be subtracted from the Physical memory amount in Windows.

See response 5 in this for some info about ram compatibilty, and some places where you can find out what will work in your mboard for sure:
Correction to that:

All the ram you have installed will automatically run at the speed ratings of the slowest module. You need to determine what that is for the modules you already have. If that isn't obvious on the labels on the modules, if you have brand name ram, it is usually easy to look up their specs on the brand name's web site by using the part number on them to search with.
If the ram is generic, that may be difficult or impossible.

If your think computer is slow with 2 - 512mb ? modules installed, adding more ram won't help much - you have other problems.

Here are the specs for your machine. It will take up to 3 gigs of ram running in dual channel mode. I would scrap the 512 chip and install 2/ 1 gig chips running in dual channel mode. The extra 512 by combining them won't make much difference and you should use identical ram for the best performance. 1 gig in each slot. A matched pair.

Thx for the link to acer support: RAM / Max RAM Up to 2 GB of DDR2 533/667 MHz memory, upgradeable to 3 GB using two soDIMM modules (dual-channel support) .
now a new question arise : does generic memory work fine if instaled? ( they cost less than the brand name one to save some bucks mainly on ebay).

See the part in Response 2 starting at
"See response 5 in this for some info about ram compatibilty,..."

What ever ram you get will work fine, providing you use your Aspire 9300 model to search for ram that will work in your model for sure. Memory Giant is one of the ones that can supply you with generic ram that is guaranteed to work in your model.
Otherwise, don't randomly buy ram using only the meagre info about the ram Acer or whatever brand name system or mboard manufacturer supplies - that's usually not enough info to ensure the ram will be compatible - unless you get ram that has the exact part number found in their tested ram list for the model.
