Ram speed? Differences Betweem 1066Mhz & 1333Mhz - Benchmarks if you got em'

Ok this thread is to ask the question about the performance difference between the two ram speeds 1066Mhz and 1333Mhz.

I personally wanted to know if the difference would be easily noticed.
Would 4/6GB of 1333 be better then 8GB of 1066??

I ask because I know more ram capacity usually is better, but 8GB is already alot and prolly overkill

I am sure many have asked the same question, or something similar before so I know this thread will generate alot of good info.

 

unless you run heavily ram-intensive programs, I doubt you will notice much of a difference. Ram is almost never the bottleneck.

Performance would be higher on a ram-intensive tasks with 8gb of 1066 in a dual channel configuration versus a single 4gb 1333Mhz or 6gb1333Mhz.

Ram speeds really dont matter unless you use the igp a lot, then you might see noticeable differences

 

It would still be dual channel on 4GB/6GB.. just 1333Mhz being the difference.

I have been doing some googling and I seem to have come to the same conclusion; its better to have more ram at those speed differences.
The only exception to this would be if you are overclocking (not), or if the speed is alot faster. Even then the super fast ram might be only a minimal increase.

If anyone has any more input, I appreciate it all.

 

The only time you'll notice any benefit from increasing the speed (bandwidth) is when you play games on integrated graphics. Every other situation, you will see zero real life benefit from any speed as timings change inversely and balance it out.

 

I doubt you'd see much performance difference from 1066 to 1866 for that matter either. RAM frequency just doesn't have a major impact on performance. Unless you are overclocking (on an unlocked CPU), there is no reason to pay a premium for fast expensive RAM. The price difference between 1066 and 1333 (and maybe even 1600) should be pretty small though, so get whatever is the most reasonable for the money.

The stuff that's a waste would be the 1866+ or other expensive fast RAM with special timings, cooling, etc... In general, there are very few laptops out there where you are even able to do real overclocking, and the m17x is not one of them.

 

+1Ghz or more over stock, across four cores is not real overclock? Could you please give me an example of one of this few laptop that can be really overclocked since the M17x it is not one of them?..

 

Sorry, I should've specified R3, since that's what the OP was referring to.

"Now, how far can you OC the bclk? This will vary by CPU and mobo, but you will most likely be hard pressed to get more than a 5% increase on a non-K/XM CPU."

Intel locks down all the non-extreme edition CPU's now, aside from a few select "K" models. Unless you get an extreme edition CPU in your m17xR3, you are not really going to be able to do any significant overclocking via the BCLK. Thus, faster memory is going to be of little concern when the frequencies aren't linked and you're only getting a 5% overclock.
