ACer 9424 RAM issue
Hi people.
According tot he specs on the ACER 9420 notebook series the 9424 should be able to deal with 4GB of Ram. So I installed a matched set Kingston. And what happens? The bloody thing only sees 3GB! Anybody have an idea OR done the same without any problem ( in which case I have a hardware issue - still under guarantee). Other question: The mainbord in the 9420 series has a dip-switch on it. ANYBODY have any idea what it is for? ( Acer doesn't seem to). |

ACer 9424 RAM issue
This is a limit of 32-bit OS's in general. They can only 'talk to' 2^32
(i.e. 4GB) memory addresses, but some of those addresses are reserved for hardware. If you want to read more about it check out this link, although it's pretty tech-y: http://blogs.msdn.com/oldnewthing/ar...22/218527.aspx wrote in message ... Hi people.

ACer 9424 RAM issue
You guys and all of your rampant speculation... Let me give you all a clue..
If you want to see more than 3.25GB's of memory, install a 64 bit OS. ALL 32 bit OS's (Mac OS, Linux Ubuntu and Windows) do this. At the Mac store they don't even offer 4GBs for 32 bit machines. wrote: its the OS.not acer I am sorry guy but you are wrong.
