Memory Upgrade

[Fred]

Planning on increasing my desktop memory.
I currently have:
128MB 200MHZ DDR SDRAM - 1DIMM

I would like to add 512 to the existing memory.
Can I do this by adding the 512 to the open slot & will it be compatable
with the existing 128?

When looking at available upgrades I see reference to PC2100, 2700, 3200.
But I see nothing that refers to the 200MHZ that I currently have.
Can anyone suggest what is my best course of action when buying.

Also, my computer will take up to 1 Gig but are there any limitaions
going over the 512 with a Win ME operating system?

TIA,
Fred

Fred,

The easiest way to check what memory is suitable for your PC is to use a
site such as http://www.crucial.com/ and enter details of your PC, etc.
and see what they have to recommend.

Win Me, like previous Win 9x operating systems can handle up to 2GB of RAM
(although often there are problems with greater than 1GB) so if you have
more than 512MB it is essential to limit the virtual cache to no more than
512MB as follows:
To limit vcache, open system.ini and add the lines
[VCache]
MaxFileCache=512000
Note that this will still mean that all memory is available to
applications but is simply limiting the amount used as virtual cache
memory See KB 253912 - ""Out of Memory" Error Messages with Large
Amounts of RAM Installed" (http://support.microsoft.com?kbid=253912).

See also:
MS KB 296773 - "Computer May Not Hibernate with More Than 192 MB of
Memory" (http://support.microsoft.com?kbid=296773). This makes reference
to an updated file vmm.vxd. Contact Microsoft, explain the problem, and
mention 296773 and you should be given details of how to obtain the patch
and the password of the day. Note that there should be no support charge
for this call other than for any telecom charges incurred in ringing
Microsoft.

RAM" (http://support.microsoft.com?kbid=304943).
