Without knowing exactally which it is, even if it is value ram it is sort of hard to tell you, but I would definately not go over 2.9 volts. My Geil DDR500 has a max of 3.1 and its pretty nice ram. Your stock volatage is probably 2.6 or 2.7 so try bumping it up to 2.8 and then run "Memtest" (google it) and see if you get any errors.
