My father has one of these and it only has 365mb of memory, with
Windows XP Home SP2.

Can someone tell me exactly what he needs to buy to upgrade the

He wants at least 1Gig.

The standard RAm for that machien appears to be 512MB, so not quite sure why
you are seeing 365! Did you mean 256? Perhaps you were reading the 'used'
amount of RAm in windows? Best thing to do is right click on My Computer on
the desktop, look at properties and that will tell you the amount of RAM.

I went to google and searched for "w3502 ram" and found loads of results -
here is one example:

It looks like the machine takes DDR400 (not DDR2). So that is PC3200 speed.
It also appears to be able to take a 1GB DIMM, so perhaps you could even buy
two of them - open the PC case and see how many RAm slots are there. if
there are 2, then why not get 2GB (a matching pair of 1GBs) - will never
need to upgrade again.

Crucial and Kingston have search engines.

Crucial says it will take up to 2x1GB DDR400 (PC3200).


Kingston says much the same thing.


KVR400X64C3A/128      128MB 400MHz DDR Non-ECC CL3 (3-3-3) DIMM
KVR400X64C3A/256     256MB 400MHz DDR Non-ECC CL3 (3-3-3) DIMM
KVR400X64C3A/512     512MB 400MHz DDR Non-ECC CL3 (3-3-3) DIMM
KVR400X64C3A/1G     1GB 400MHz DDR Non-ECC CL3 (3-3-3) DIMM
KVR400X64C3AK2/512     512MB 400MHz DDR Non-ECC CL3 (3-3-3) DIMM (Kit of 2)
KVR400X64C3AK2/1G     1GB 400MHz DDR Non-ECC CL3 (3-3-3) DIMM (Kit of 2)
KVR400X64C3AK2/2G     2GB 400MHz DDR Non-ECC CL3 (3-3-3) DIMM (Kit of 2)

The machine uses a Celeron D at 3.2GHz, and ATI Radeon Xpress 200 (RS480)
I guess it has two RAM slots.

The specification section of this page, says it ships with "1 x 512MB".
Your father could use an additional 512MB stick, as the cheapest way
to get to 1GB total.


To verify it really contains "1 x 512MB" now, and not some other configuration,
use CPUZ.


Apparently, the RS480 is a dual channel chipset. What that means, is
you could get slightly more memory bandwidth, if the two memory modules
installed were matched. There aren't usually a lot of ways to make a 512MB
module, and the usual way is with 16 chips. If you were to blindly buy another
DDR400 stick at the 512MB size, chances are you'd get another module
with 16 chips on it. There is a small chance you could get an 8 chip module,
and advertisements are generally pretty poor at giving that kind of
detail. Purchasing a matched pair of some capacity, would be another
way to solve the problem, but would leave you with a spare 512MB stick
sitting around. (A spare can come in handy - I've had a spare DDR sitting
around for a couple years, and actually needed it for some testing
recently, so it saved me a trip to the store.)

So if you went to a 2x1GB configuration, buying a single kit would
solve the matching problem for you. This 2GB kit of 2x1GB isn't
that expensive, at $67. The reviews look pretty good (less than
the usual number of bad, out of the box experiences). So if you
aren't on a tight budget, even a 2x1GB config is within reach.

KVR400X64C3AK2/2G  DDR 400 (PC 3200) 2.6V  CAS3=(industry average type)  $67


If you only want to buy another "1 x 512MB", this is an example of a
16 chip module.

KVR400X64C3A/512  DDR 400 (PC 3200) 2.6V  CAS3=(industry average type) $21


Memory which is CAS2.5 or CAS2, answers a request for data in fewer
clock cycles than a CAS3 stick. But again, the difference are minor,
and don't usually justify a big price increase. In the case of your
computer, my concern with using any higher performance "enthusiast"
type RAMs, would be a lack of voltage adjustment on the DIMM slot.
Some of the "hot" memories, need a bit of extra voltage to work
well. With the Kingston products above, it should be "plug and
play", and no tuning needed.


Re: emachine W3502 memory question

Thanks GT and Paul.

He does have 512MB, have no idea where the the 365 number came from.
He went to Best Buy, Circuit and one other store yesterday and none of
them had DDR400. (had the hanger for it but were out of stock)

Is this type of memory not very popular?

Sure it is popular. Just buy it online if a local store cannot help you.

I got mine from ncix.com (because I'm in Canada, and many US online sellers
don't ship here).  You may see me post a lot of Newegg links, but I
actually cannot buy anything from them. They don't ship to Canada.

It's hit or miss what you can be sure to find in a local
store at any moment unless you only need a generic type of
part like "Hard Drive" rather than some specific make,
model, capacity, etc.


That link should show 512MB and 1GB DDR400 (aka PC3200)
options.    Newegg ships pretty fast, usually about 3
business days later the part arrives.

Thanks again guys. He's gonna get it from Newegg.
