I'm sure it was DDR. I t doesn't really say on the module. but I ordered it specifically for the Presario.
The invoice lists it as " 512MB SDRAM SODIMM (144 Pin) LD 133MHz PC133 FOR Compaq Presario 1700T"
How can I get to the "Setup Menu" ? It "boots" to the Compaq "flash" screen, but there is no "Press F1 [F2, F10, etc) for Set-up message that I can see.
