Slow vs fast ram

[Hood]

What sort of bs statement is that?
How about this: if you aren't excited about the performance of your computer, you are not an enthusiast.

That's a good one too. By that I meant I have done without certain things so I could spend the money on a part that was really beyond my budget. I am semi-retired due to health reasons, and on a very limited budget, so upgrades require sacrificing something or an unexpected windfall. Since I consider myself an "enthusiast", I often find myself wanting to buy the latest and greatest hardware, but being a realist on a tight budget, it's not always possible. Also it's best to wait through at least 2 or 3 generations of hardware to do a major upgrade, to make it worth it. That's why I want my Ivy rig to be as fast as possible - so I can safely skip Haswell and Broadwell. My next major upgrade should include DDR4 and SATA Express, or it's not worth it, so it looks like I'll have until 2015 to save my pennies.

You hit the nail straight on the head

As for the op's Q I had a set of 2133 cas 9 1.50v dominator platinum 2x4gb sticks.
upgraded when I didnt need to as the platinum sticks would clock up very well but the numbers just didnt scale up with the clocks

I moved up to a set of Kingston’s HyperX 10th Anniversary Edition memory 4x4gb 2400MHz c11 sticks and the difference was impressive to say the least... I never looked back at the corsair sammy chips. So imo I think you cant go wrong upgrading. The numbers prove to be way faster and these things beat alot of 2666mhz sticks out there on the market.
check out Daves review here, you might be surprised

That review is very synthetic heavy. Like who cares what Sisoft Sandra, 3D Mark 11 or Superi says. I don't make my purchased based on random numbers.

The non synthetic tests shows it virtually makes no difference. In most situations that review shows the 1600MHz sticks going toe to toe with the 2400Mhz Sticks. Not sure that review helped your cause.

Nothing wrong with 2133Mhz Sticks, if I was building new I would recommend shooting for the highest frequency possible. But in the OPs case its just silly to remove his good memory sticks and spend 80€ for a superficial boost.
