    You have to use DDR2 at 533MegaHertz, or 667MHz. That is PC2-4200 and PC2-5300, respectively. (SO-DIMM for laptops, and PC2-4200 is also known as PC2-4300 ) Ram memory Always has to be in Slot 1. (DIMM 1)The Processor reads Slot 1, First. What is the manufacturer name, and manufacturer code on the ram? You may have High-density ECC ram, which you cannot use. (Is it from Ebay?) It may be high performance ram memory, that uses above the factory default voltages for the laptop. It may have the wrong ram timings.  Post back in a Comment.

Probably a faulty ram socket. I have seen a few acer's with the same problem. There is a sort of fix but it's not normal. It was to insert something between the top ram board and the plastic cover just to press down on the ram board, not loads of pressure but enough to connect it properly.
Do it at your own risk though.

SOURCE: Problem with upgrading my acer extensa 5620z memory to 4GB

The Extensa 5620z comes with 1GB of DDR2 memory. That's two sticks of 512MB. This unit technically supports 4GB; 2 x 2GB modules. However, unless you're running a 64-bit operating system (if you have to ask how you'd know, trust me... you're not) then only about 3GB will be usable. There's no fix for this, it's just a fact. All standard 32-bit operating systems are coded this way
If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

SOURCE: Acer Aspire 5601 4GB memory upgrade problem

did you try swapping the order of the memory sticks in the machine? for example, if you put stick 'a' in slot 1, and then put stick 'b' in slot 2, did you reverse it and put stick 'a' in slot 2 and stick 'b' in slot 1? sounds corny but i have fixed many computer memory issues in that way. also - have you verified you did not get a bad memory stick? can you boot (and will the computer recognize) stick 'a', then replace it with stick 'b'? try that and post what you find out here.

I have Acer laptop Aspire 5570z module Zr1 with memory 1GB I want to increase memory 2GB or 3GB Is it possible or not What will be the expenditure?


Your laptop's RAM is upgradeable to up to 4 GB using two DDR2 533/667 MHz SODIMM modules.

So your upgrade options here are:
1. Buy a 1 GB DDR2 533/667 MHz SODIMM module & install it to get a total RAM of 2 GB (Price around US$ 25).
2. Buy a 2 GB DDR2 533/667 MHz SODIMM module & install it to get a total RAM of 3 GB (Price around US$ 45).

Cpu upgrade options on acer aspire 3660


You can upgrade your machine at your own risk but be certain to use a clean workspace, proper dis assembly instructions and have a grounded wrist-strap. I would make sure you have the latest bios for your machine and any firmware updates applied as well for the other devices in your machine.

Check out this thread as some have put a Dual-Core cpu in this machine.

Acer Aspire 5601 4GB memory upgrade problem


Acer systems are picky about the type of memory you use.
What is your RAM Speed on the old chips compaired to the new chip

You may have to reorder the same type of speed memory

Try this website it will tell you what will work with your system

Problem with upgrading my acer extensa 5620z memory to 4GB


Hi there.
I recommend you get another stick of SODIMM to replace what seems to be the faulty stick.
If you are using XP or Vista X86 (32bit) then the system will only recognize 2.8 - 3GB of memory, only 64bit operating systems recognize the full 4GB.


Good luck ad thanks for using FixYa!!
