I just got a 512 stick in today. I tested it, and it ran @ ddr 433 with timings of 2-2-2-11 perfectly stable. This was with DEFAULT voltage! Does this mean it is bh-5? I don't know why I got it sooo cheap if it runs so good! The stick of ocz ram in the sig will not run at this speed (reboots before windows), but together in Dual Channel they run GREAT @ 2-3-2-11. Also, in windows, when you right click my computer.......it is suppose to say 1.00 gb right? I though it would say 1024 mb........
