msi 790 fx-gd70 thread

[inferKNOX]

Hi everyone, as you can see, this is my 1st Post.
I just bought this mobo recently and believe it or not, have read through this WHOLE thread! Why? Well I got quite a bit of general PC experience and am a PC Tech actually, but have no overclocking knowledge whatsoever.
I'm looking to overclock the CPU about 20% (3.84GHz) but if it proves too hard, I may fall back to, what seems to be for most, a pre-voltage tinker clock of about 3.6GHz. Hoping to keep Cool'n'Quiet on too, during overclock.

(I hope I'm not veering things OT, if so, please at least redirect me, but I think this all applies to this motherboard.)
So here's some questions:

1. Is overclocking memory necessary, because I bought A-DATA DDR3-1333 RAM that I don't think is very overclockable at all & is not an option for me.(Answered by shadow_419=post #819)
2. I noticed SNiiPE_DoGG bought the OCZ Platinum AMD Edition, which is lower voltage wise compared to the OCZ Platinum Enhanced Bandwidth Edition I've had my eye on (extended RAM heatsinks are not an option for me). The AMD edition says it's meant solely for AM3, which is hard to sell later, so my question is, is the higher 1.9v vs 1.65v bad for the Phenom II? (Answered by TurboDiv=post #816)
   I was thinking of getting the 1.9v and trying to dail down the voltage as best I can. Does that sound ok?
3. What is the benefit of NB overclock, is it speed gain, stability or to enhance the ability to overclock the CPU and/or RAM?(Answered by shadow_419=post #819)
4. Lastly, does overclocking decrease the lifespan of components? If so, it is significantly so? (obviously I don't mean Xtreme overclocking, just a 24/7 OC)
   I'd also like to get maximum life out of the equipment, hence my modest overclock ambitions.(Answered by shadow_419=post #819)

I hope I get some responses, looks like I got to this thread quite late when most have moved on.

@xplosiv: I saw online, that the OCZ3P1600EB4GK RAM is successfully used with this board. It's the same one I'm eager to get. Note the EB is for Enhanced Bandwidth.
Also, the 1.3 BIOS supports the 550, and the boards currently being sold should already have it, so I think that's another yes.

@Slave1974: I'd recommend u get the same Enhanced Bandwidth OCZ as I was talking about in my 2nd question and xplosiv is asking about.
