- Would you do me a favour? Download Geekbench 3, run it, and post a screenshot of the resulting browser window?

there you go..i did asked some advices from other people including Kingston..they said the RAM that i enquired not compatible with my MBP..

so let say i get the Kingston HyperX Impact SODIMM - 16GB Kit (2x8GB) - DDR3L 2133MHz RAM....my macbook can runs at 2133mhz too?
- I'd say no. But that's why I was asking Erdbeertorte to run Geekbench. The Intel CPU only supports up to 1600MHz, so my suspicion is that his About this Mac only reports what's in the machine, not the speed it's actually running at.

- I will. Quite loving that setup. I'm on 1600MHz as well (Corsair Vengeance), but feel a bit cheated if it can actually run higher.

What sort of speeds are you getting from those lovely 850s?

well at this moment this Data Doubler is the best..i used the normal aluminium bracket before...i dont like it...dont reallly care about wether the color of that data doubler match with my SSDs & RAM...by the way..OWC RAM are sucks!!!! 2 times i bought it..both was a big failure...before this i used ADATA RAM...and it runs smoothly no complaints...i just got this kingston RAM last week....so far so good..but really wish if can go 2133mhz..hahaha

- Yup. Certainly is the best. I'm just weird in liking the nicely colour-coordinated look of my internals.
I'm currently eyeing the MCE OptiBay Extreme. It's designed to provide stable SATA III speeds on 2011 machines with SATA III, which otherwise have been known to be flaky. I'm wondering if it will also provide stable SATA II speeds with SATA III drives on 2011 machines that only have SATA II optical bay speeds (such as mine), which has otherwise also been known to be problematic. Any idea?

What happened with your OWC RAM?

OWC RAM?? it doesnt work like how i expected....thats all i can say...
well regarding the Optibay..i cant comment anything because im not really know much about it..but im happy with this OWC Optibay..

- The word from Primate Labs/Geekbench is that Geekbench reports whatever the OS reports.
So now the question becomes whether OS X reports the speed based on some self-identifying information the RAM modules transmit, or if it reports it based on the actual speed it's running at.

I'm having trouble seeing how it could possibly run at 2133 when the CPU doesn't support it according to Intel.

Hey

I just updated my MBP 17' Late 2011 with that Kingston 2133 Mhz and it shows that worked on full speed! (yay). For test, my first attempt was check will it work on my iMac 27' Mid 2011 with full speed. But it only work on 1333 Mhz speed.

- I still can find no good reason this should work. The limitation of the Core i7 should be the deciding factor, and it only supports 1600MHz.

Can you think of some reason this would work other than the fact that it seems it does (I'm still skeptical that those System Information numbers actually mean what we think they mean)?

I have no clue why it worked. With that RAM My MBP working blazing fast! Seems to be legit. Later i will do some tests and results post there.

I look forward to seeing some test results, as I'm considering going from 8 to 16GB and if the higher speed RAM works and provides an effective performance advantage over the lower speed RAM.

My typical use is running Parallels and a few open apps in OSX one of them being FireFox with many open tabs, and I guess the additional RAM would be a benefit.

Q1 - Can I expect significant performance gains going from 8GB to 16GB

Q2 - Can I expect significant performance gains from the 2133 vs 1600

Thank you for answering the geek bench-team.

So - running geek bench with 1600 and 2133 Mhz Ram under sane conditions should be z´the only way to find out… apple shurely never ever will inform you because they want to prevent customers from upgrading with 3rd party products… sadly…

upgrading the 2nd disk from HDD to second sad or just exchange the sweet little SSD by a much bigger SSD would though be perhaps the best thing to do for more real-life performance the Thread Opener, I guess? Apart from upgrading to 16 GB Ram (1600 MHz) , of course…

data doubler is though pretty nice… and I´d still like to know if the 2133 Mhz RAM is just ACCEPTED to use it with 1600 speed (If I recall it correctly, this was stated in a MacPro-Thread for other Ram and other speed as well, showing also that there is no important changement on performance)
OR:
if the 2133 RAM will really run with its full speed - even than the question is if this is important in real-life...

Q1 - Depends on your usage. But looking purely at the amount of RAM, yes, 16 GB will be able to provide lots greater performance than 8 GB.

Q2 - Essentially, no. The gain from the jump from 1333 to 1600 has been shown to be in the 1-2% area. A very unscientific extrapolation would be that since that 20% increase in clock speed yields 2% increase in performance, the 33% increase from 1600 to 2133 should yield a 3.3% performance increase.
IF it actually runs at that speed.

Hey!

So, i run Geekbench 3 on my MBP and iMac. When i see results, fell shocked at all...

What be in a test: MacBook Pro 17' Late 2011 (Core i7-2860QM, 16Gb 2133Mhz RAM)
iMac 27' Mid 2011 (Core i7-2600, 16Gb 1333Mhz RAM)

Attached two pics with memory results. How we can see, its twice speed bump!

If needed, i saved full results of Geekbench test.
