Hi

I purchased 2x1gb Kingston RAM to upgrade my Dell Optiplex gx620 (mini tower) to 3gb on Windows XP. I inserted them in two of the 4 slots, next to each other and left the existing 512k RAM in the remaining 2 slots.

After switching the PC back on, it just beeped and would not start up. I subsequently removed the 2x1gb RAM, and replaced them with my old 512k RAM, and the PC booted up and is back to the original total of 2gb.

Is there a possibility that the 2x1gb RAM I purchased are defected, or not compatible with the Dell Optiplex gx620?

Got to be more specific. What brand of memory did you get exactly? You said you bumped it to 3 but then you removed the new ones and put in the old ones? Sometimes computers can't adjust to memory properly. These are meant to run DDR2 533/667, but i have put 800 in these guys with no issues.

Also how many beeps did it beep at you or what it just one long beep?

Thank you for taking the time to respond to my inquiry. The new memory I purchased are labelled per below, and the beeps were short beeps when I started up the PC. So I just put my old memory back so I could continue to use my PC in the meantime.

Odd. Did you try more than one DIMM slot? Maybe bad slot? And next time pay attention to the beeps and let me know if the interval between beeps is short or long. Like if it was a Beep beep beep ..... Beep. So a short shot short long. This will help me diagnose what is going on.

as for as memory goes that should work just fine. not sure why its giving you issues.

You can't just put the two 1gb next to each other. Refer to your manual. You need to put them in slots 1 and 2. The slots are actually in the physical sequence of 1,3,2,4. Therefore put one 1gb in slot 1 (the top slot) then miss a slot and put the other 1gb in slot 3. The memory has to be in matched pairs so don't use the other two slots unless you have a pair of eith 512mb or 1gb to put in there. One 512mb on its own won't work.
Good luck
