sounds like you have an older MoBo.  Do you have another expansion slot??   You could probably find another 256 in the dumpster and test it out but if your looking to put 1Gb in than you could get the Samsung or the hynix cheaper than the Kingston 512's

Travel to Crucial.com and enter the machine info and/or run the online scanner and it will tell you exactly what type and how much RAM can be added...
You can then shop around your area for the best deal.
