said by signmeuptoo94:Is there a good way to identify DDR 1/2/3 RAM without a reference? A friend is bringing some RAM for me to check out to see if I can use it, but I cant just look at a stick and know it is DDR 2...
If all you want to know is if it's DDR vs. DDR2 vs. DDR3 --
sure you can! Take note of where the notches in the DIMM are (note the ruler at the bottom). I've used this visual method for years with DIMMs lacking labelling. Alternately for DDR1 vs. DDR{2,3} you can count pins (for standard "desktop" or "server" RAM (i.e. not SO-DIMM)), DDR has 184 pins while DDR2 and DDR3 has 240 pins.
For things like max speed and timing/SPD settings, no, you can't get those from visual inspection.
