Specs: Windows XP
I have two different RAMs one of 1 GB & the other is 512 MB RAM. 512 MB is the RAM that i brought last 5 yrs back and 1 GB RAM is the one which i brought 1 yr back. Can i use these two RAMs so that i can get 1.5 GB RAM in total. Well the cache memory output of both RAMs is not equal. Am using Intel DDR 102 GGC2 Motherboard with Intel P4 Processor. One of My friend said it will damage the hardware if we insert these two RAMs. so plz guide me .

Your board:

• 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...
