I just purchased a used Compaq Presario 2596US laptop and I want to add another 256MB of memory. Currently it has the following RAM: Infineon HYS64D32020GDL-6-B 32M x 64 SDRAM PC2700S-2533-0-A1 256MB, DDR, 333, CL2.5 All the memory configurator's tell me that this laptop should have DDR 266 PC2100 in it. I would like to use one of choices if possible: Kingmax 256MB 200-Pin DDR SO-DIMM DDR 333 (PC2700) Notebook Memory Module MSAB62D - OEM or Kingmax 256MB 200-Pin DDR SO-DIMM DDR 266 (PC2100) Notebook Memory Module MSDB62D - OEM These are available from newegg.com for under $21.00 (great price!) WHICH ONE SHOULD I USE? THANKS!!! PCBUILD maintains hundreds of useful files for download visit our download web page at: http://freepctech.com/downloads.shtml
