Having problems with your IBM PC 350 PC Desktop ?

RAM Upgrade Acer ASE380-UD421A. It appears that when I use all 4 memory slots this falts the machine it beeps and won't start. Okay, the machine came with 2 - .5 gb memory boards and two other empty slots. I bought 2 - 1 gig PNY DDR2 memory boards. I put those into the empty slots for 3 Gbs of memory, the machine beeped and wouldn't start. I took the board in the slot 4 out and it worked, I had 2 gigs of memory. I put the two new boards in the first two slots and nothing in the 3rd and 4th slot,


Answers :

How much memory your Windows OS will recognize depends on which version of Windows you are running. 32-bit versions of Windows will see (and utilize) only 3GB or 3.5GB. To utilize more memory, install a 64-bit version of your OS. More information about OS memory maximums can be found at http://www.crucial.com/kb/answer.aspx?qid=4251

\015\012Not only is there a maximum amount of memory that your computer motherboard can accept, there is also a maximum amount of memory that your operating system (OS) can accept. For instance, when you install 4GB of memory in a 32-bit Windows system (the most common version; 64-bit systems are typically used by high-end users), your system reports only 3GB or 3.5GB.
\015\012First , we can assure you, there isn't a problem with the memory. While Windows allows for 4GB of memory to be addressed, it does not equate to 4GB of physical memory. \015\012Some of the memory (regardless of how much you have installed) is reserved for use by the devices that you are using, such as a graphics card, PCI card, integrated network connections, etc, meaning it is unavailable for use as normal main memory. \015\012Upon startup, your system calculates the amount of memory needed for these devices; if you haven't maxxed out the memory in your system, it's invisible to you, and all your physical memory (the installed RAM) is available for use. However if you've maxxed out the DRAM in your system, this amount will be deducted from your physical memory, so you can't use 100% of your DRAM. \015\012The maximum memory limitation varies by operating system, For instance, the 4GB memory limitation doesn't exist in 64-bit versions of Windows.
