Ask your self this question:
Is all the bandwidth at 1333 used by the processor? In fact is all the bandwidth at 1067 used by the processor?
Limit your answer to the use on a desktop system, not server....and be truthful.
for 99.555555555% of end users the best way and safest way for them eek out more speed is to lower the latency, if you can increase IMC clock then add this also but you can leave the ram speed and voltage alone.
There will be the 200 users here on XS who run 2000+, we all know that but 200 users here does NOT pay my salary, the money is with the other 99.55555555555% that populate the world and want to have a little extra for nothing, hence play it safe and go with subtle tweaks that gain you increases without the need for huge vdimm or vcore increases.
So yes I know running 2000 may be slightly faster, what i am talking about here is doing it in a safe 24/7 environment where people pay for the ram and the processors they use and are not sponsored or rich enough to not care. I get freebies, I think we all know that, but i try to advise caution and look after all manufacturing parties involved...I have killed more ram, more CPU's and more motherboards than most testing so i tend find out quick what is the best way to approach new tech. In this case I feel its best that end users use low vdimm, they get away from thinking they have to run 2000+ until we can produce those dimms in quantity and at a voltage that does not harm. Remember most of the guys here have Micron DDR3, this still needs high voltage even on i7 for high clock speed so advising low latency really is the way to go.
While I am waiting for the CPU's to arrive, run some tests for us showing a fixed CPU speed, differing ram speeds and the effects of latency on writes and access. Push this into some games so we can see where the FPS are going and then plot a correlation of ram-speed Vs FPS Vs ram voltage. Then we can see just how much gain there is at 2000 over say 1500 with 9-9-9- at 2000 and 5-5-5- or 6-5-5- at 1500. factor in the risk values also running 2000 with higher vdimm and then we can all look at whether its worth it. Best you use older Micron D9 for this test, not the newer (various manufacturer) low voltage DDR3 then is just being released (we are testing too
) as most jumping to i7 will do so with the ram they have to hand...not go and buy more.
Don't ask me to do this though...i will get 1 CPU and in no way am I risking killing it.
