|"What will happen if i install a (2048x1) DDR2 SDRAM on a SIMM slot, will it damage the PC or it just won't boot"|
Crucial states, "Each memory slot can hold DDR2 PC2-5300 with a maximum of 1GB per slot." I can't tell you for sure what will happen but it's highly unlikely you'll damage anything. My guess is either the system will refuse to boot or the 2GB stick will be recognized as 1GB.
HP, Crusial and you are all wrong! I've installed a 1x2048MB DDR2 800MHz in a DIMM slot it is all ok .
My Compaq Presario SR5080CF CTO now have
1x2048MB 800MHz, 2x512MB 667MHz and a 1x256MB 533MHz of DDR2 Dram.
