hi there, i have a gateway mx3225 laptop runnin xp it came with 256MB ram stick in it, i looked up the max ram that i can use and everything showed 1GB so i bought a stick, but when i install it, nothing will run on my comp. the power light comes on, but that is all....... i had a 256mb so-dimm 200 pin DDR2 533 mhz pc-2 4200 stick in it, and i bought a 1GB so- dimm ddr2 pc2-5300 667mhz, which on the package showed would interchange. the guy at the store even pulled up my comp specs to make sure it would work. any info would be greatly appreciated.That exact model is not LISTED here: http://www.crucial.com/index.aspxthe guy at the store was having the same problem, on the crucial site.then he SAID he found my model somewhere.It appears to be the right specs and it should work. It's possible that the 1GB is defective, so take it back. If a replacement doesn't work, you'll have to contact Gateway.
http://support.gateway.com/s//Mobile/Q106/Magic/1008829nv.shtmli took it back, i am gonna BUY another one some where else and give it a try. what is FUNNY the stick was a kingston, and according to their site, 512 is the largest i can use
According to Gateway that machine will take 1G...Just to say that I had the same problem with a Sony laptop. The problem was that the RAM appeared to clip in but actually wasn't pushed in enough. Make sure that no part (or very little) of the copper connector is showing above the slot.you can just barely see the copper when it was installed. i did some reading up and this issue seems to be a problem on the mx3225. one guy tried 4 models of 1gb ram before he got one to work. so another guy having the same problem bought the same part number ram stick and his worked.unfortunately it is like $99 for a stick, but thanks to ebay i grabbed one for $19 ill post the results when i get it installed.RAM incompatibility...i figured i would post this for everyone to read, it may save other folks from trying to figure out whats going on..........


We no longer make 1GB modules that will work in this computer. We can no longer get the low density chips that are compatible with this and similar computer. You should return this memory to your place of purchase and see what parts Gateway recommend for this computer.
