Hye guys, I'm planning on changing my sets of Ram. The only CL7 ram that is available at my country is CMG6GX3M3A1600C7 and Team Xtreme 6GB 2000MHz CL9 kit.

I need to ask several questions about this sets of ram CMG6GX3M3A1600C7 (7-7-7-20 @ 1.65v)

1)what's the difference between the new "CMG" kits compare to the old "TR" kits.

2)Heard that a lot of dominator GT faced premature death, but most of them are 2000MHz kits, so are this kits effected by the "premature death virus" also?

3)So far I googled, a small amount of people saying that this kits are not a better Overclocker compare to the old one, but nobody posted any proof for it so if anybody have this kits I need your help since it's a very expensive kit so I need to read as much of infos as I can to be really satisfied with it.

4)I'm interested with Team Xtreme 6GB 1600MHz CL7 kit but it's not available in my country for triple channel. Here's the question. Can i buy 2 of those Dual Channel and use only 3 of the sticks (keep or sell the other stick) + (I know it's dumb but it's way cheaper than the Dom GT kit). Is it possible to do something like that? Anybody tried this before?

5)Any extra advice regarding my ram issue.

6) My system is i7 920 D0 + DFI UT + HD4890 + TRUE 120 Push and pull~

Thanks in advance for all.
