i5 13" MBP, 8gb 1600Mhz, 16Gb 1600Mhz, 1866Mhz?

The performance increase that you will see from faster memory will be tiny. Literally, it won't be noticeable in intensive applications.

Just had a further look at the Pixmania website, definitely go for the Corsair Vengeance 8GB 1600MHz kit that you have listed. You won't need 16GB of memory, and the 1866MHz kit will not give you a performance boost that is worth 30€.

What about the argument regarding ram speeds for the Intel HD 3000 (as well as the oncoming HD 4000) will improve FPS in games?

I will provide benchmarks for the 1866mhz if we have someone else with the same specs as mine with 1600mhz and 1333mhz to show the difference.

Edit: I realize you don't believe the performance boost is worth the money, well what about the $200 (student discount) upgrade from the 2720qm to the 2820qm (now 2760qm to 2860qm) just for .1ghz and 2mb l3 cache?

Have you done any tests? It actually gives a decent boost to the Intel HD 3000, kinda of like over clocking one's video card memory speed.

I have done some tests between 1333 MHz and 1600 MHz using the HD3000. It gave me an extra 1.5 fps in the Cinebench 11.5 GPU test. It also gives me an extra 400-500 points in Geekbench. These are both valid points for bragging rights, but not much else.

I have done the tests with 1333 MHz and 1600 MHz. It would be great if you could provide figures for 1866 MHz RAM. Please use Cinebench 11.5 so that we have a valid comparison.

Good point with the memory, my mind naturally assumes that people don't game on the MBP 13", even after reading that they will

However, I wouldn't be surprised if the jump from 1600 to 1866MHz made very little difference, but this is just guessing. Even so, I wouldn't say that the price difference would be worth it.

As for the 2760QM vs 2860QM...I'm a little confused, we're talking 13" MBP here...?

1866mhz works perfect in my 2.3ghz i7, but there is no 16gb for 1866mhz though. I would love to see it soon!

I've got a MacBook Pro 8,2 Quad Core 2.3ghz i7 as well. Are you using THIS ram by any chance?

http://canadacomputers.com/product_info.php?cPath=24_326_327_609&item_id=046261

I'd like to upgrade my Macbook Pro for some more faster ram, but I remember reading months back how Macbook Pros were having difficulty with the 1866mhz RAM from Kingston.

Any input?

I have read multiple times that 1600 MHz RAM works in early/late 2011 MBP's
I think it was corsair or ocz RAM.

 

[M5RahuL]

I found that my MBP is:

Intel 6 Series Chipset
Vendor: Intel
Product: 6 Series Chipset
Link Speed: 6 Gigabit
Negotiated Link Speed: 3 Gigabit
Description: AHCI Version 1.30 Supported

It should accept the 8GB or 16Gb 1600(1866)Mhz?

Can anyone tell me how to check / get this info for my MBP ?

I upgraded to 8GB but checking now it shows running at 1067 Mhz

1600mhz RAM has been verified to work on MacBook Pros for a long time. I'm looking at getting 1866mhz. I do a *lot* of graphic design, so I'm hoping the faster RAM will benefit me.

Looking at this RAM: http://canadacomputers.com/product_info.php?cPath=24_326_327_609&item_id=046261

It states CL10, which I remember reading here on Macrumors there were problems running RAM with anything above CL9.

I can get the same ram but in 1600mhz form at half the price, literally... which makes me wonder if 1866mhz is even worth it.

It is only a 200 MHz give or take increase not worth it IMO since I (think) you are in NZ like me you will be better of with the 1600 MHz RAM.

 

[TheOriginalKi]

Sorry to hijack but does any one know if 1866mhz RAM will work with a 2.3 i5 early 2011 13" MBP?

 

[yatoyally]

Best solution and price

I have just order this one:

http://www.tpoinformatica.com/kingston-16gb-2133mhz-ddr3-non-ecc-cl11

What do you think about it?

 

[drsruli]

I have been instructed to "max out" the RAM on MacBook Pro "Core i5" 2.3 13" Early 2011 (C02FK6PEDH2G). Assume that price is not a factor. DDR3L is preferred over DDR3, the next criteriom is maximum size, and then speed. If I could find DDR3L 32GB (2x16GB) 2133mhz CL9 would this be my dream ram? Would it perform in this machine? Seriously, will the 16GB 1866 RAM work for this model?

 

[Samuelsan2001]

16gb is the maximum and it won't run the 2133mhz, to be honest just use the same as what it came with, far less chance of issues and it really will make no perceivable difference to the performance.

- You should use 1333 or 1600 MHz. Anything above is a waste of money. And beyond 16 GB won't work either. And there's no reason to prefer DDR3L for that machine, since it will just adjust to the DDR3 voltage the machine requires.

The impression that I got from Crucial was that these Macs could use the lower voltage.

ANY increase in performance will be justified. If the 1866 RAM will work, then I should use it. Will it?

 

[JTToft]

- They can't. I'm sure Crucial hasn't said or stated that they can. The modules will work fine because DDR3L modules (which are 1.35V) are designed to work with machines that require regular DDR3 (which is 1.5V).
In other words 1.35V isn't preferable over 1.5V. It's equally as good.

- 1867 MHz will probably work, yes. But just like 1.35V modules, it will work because it's designed to be compatible, not because those 1867 MHz will actually be utilised on a machine which can run only up to 1600 MHz.
Similar to the way a SATA III drive will work on a computer that only has SATA II.

You can purchase 1867 MHz DDR3L 1.35V modules. But they will work identically to 1600 MHz DDR3 1.5V modules in your machine.

 

[drsruli]

Hmmm... some posters seemed to indicate performance gains , however slight, with the 1866 RAM.

I guess that you did answer my question. Having said that, considering the price difference right now is slight, I should still get the "best" RAM that will function, with an eye towards cannibalizing it when the machine is ultimately retired. But I need to know that it will DEFINITELY work. (That should have been my first stated criterion - the RAM must definitely work.)

- Well, that's a completely different consideration. If you factor that in, it may make sense to "overbuy". But strictly for the machine you mentioned, it doesn't.

If you have any side by side performance comparisons or benchmarks between 1600 MHz and 1867 MHz on the same Mac, I would like to see it.

 

[drsruli]

AH... many of the posts IN THIS THREAD indicate that there may be a small boost with the faster RAM.

BUT - Will it work (reliably)?

- Much of the stuff in this thread seems to be old information or purely theoretical musings.
I would get 16 GB 1600 MHz with as low a CAS Latency as possible (which is probably CL 9).

well im using MACBOOK PRO 13INCH MID 2012 2.9ghz i7 and 16GB 1866mhz RAM for a month...its runs super smooth BUT kernel panic always happened ..my Macbook restarted by itself....so i changed back to 1600mhz..there not much difference btween 1600mhz & 1866mhz..maybe 5%-10% bit faster but that kernel panic damn annoying....
