Since Crucial has gotten some sense back and prices on DDR are back over 60 for a 256 stick I am starting to look around. I went to the Mushkin site and they have 3 different types. Could anyone clue me in on the differences. One is BASIC, one says nothing special, and one says High Performance. a 512 BASIC stick goes for 112 and seems too good to pass up. Can anyone offer some insight? (oh building an amd 1600xp on epox 8hka+ with gainward gf2 ti500 golden). If you can suggest something else then hit me. Oh also, i saw and FS/FT post about 2700 DDR... can I use that and a 2100 stick at the same time?
