Please log in for more thread options 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 memory. He wants at least 1Gig. | |||||||||||||

Please log in for more thread options 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: http://www.memorystock.com/eMachineseMachinew3502.html 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 says it will take up to 2x1GB DDR400 (PC3200). http://www.crucial.com/store/listparts.aspx?model=W3502 Kingston says much the same thing. http://www.ec.kingston.com/ecom/configurator_new/modelsinfo.asp?SysID=33012 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) chipset. 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. http://www.emachines.com/support/product_support.html?cat=Desktops&subcat=W-Series&model=W3502 To verify it really contains "1 x 512MB" now, and not some other configuration, use CPUZ. http://www.cpuid.com/cpuz.php 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 http://www.newegg.com/Product/ProductReview.aspx?Item=N82E16820141308 http://www.valueram.com/datasheets/KVR400X64C3AK2_2G.pdf 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 http://www.newegg.com/Product/Product.aspx?Item=N82E16820141424 http://www.valueram.com/datasheets/KVR400X64C3A_512.pdf 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. HTH, Paul | |||||||||||||

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? | |||||||||||||

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. Paul | |||||||||||||
