|Your board: http://downloadmirror.intel.com/151...|
• Two 240-pin DDR2 SDRAM Dual Inline Memory Module (DIMM) sockets
• Support for DDR2 533 MHz and DDR2 400 MHz DIMMs
• Support for up to 2 GB of system memory
If the 2 sticks of RAM are the same type (by type I mean speed, not size i.e. 512 Mb, 1 Gb) it should work just fine - the 512Mb+1Gb. If they weren't the same type (one 533 Mhz and one 400 Mhz), the memory will only function as fast as the slowest speed of memory in the memory slot.
As far as RAM damaging anything, that's a non issue really. Just make sure you unplug your system from AC power and ground your self (your body & hands) to discharge any and all static electricity before working on your system, and avoid working on a system while on carpeting or even standing on carpeting.
If the motherboard doesn't recognize or like a certain type of RAM, the system will beep at startup and give you a beep code.
Just another stupid saying...
