Hi,

As ever, i find the slight variations in numbers connected with RAM a bit confusing.

 

I just upgraded my RAM in my early-2011 Macbook Pro, so I was wondering if I can give these two SODIMMs to a friend who has a mid-2010 (2.4Ghz Core 2 Duo, 13") Macbook Pro.

 

According to the Crucial site, the numbers differ, but they are both DDR3. The RAM I have available is DDR3-1333 PC3-10600 CL=9, whereas it recommends DDR3-1066 PC3-8500 CL=7 for the 13" machine.

 

Do any of you know whether newer RAM modules can be put in the slightly older machine (or is this just a completely idiotic question)?

 

Thanks,

Tobias

    You can't use 1333 MHz RAM on a Mac designed for 1066 MHz RAM. Also, you want to install a memory stick complelety different than the one that a Mid 2010 MacBook Pro.

     

    Your friend has to buy new memory designed for that MacBook or that meets the requirements of that MacBook Pro. It's possible to buy memory in OWC or Crucial

    Thank you, Mende. I assumed this, however wondered whether there was a retrocompatibility as in the case of hard drives.

    In principle I agree with mene1's advice.  As an experiment when I installed new Ram in my late 2011 MBP, I took the original 2 GB RAM srticks and inserted them in my 2010 MBP.  It worked but the RAM was downclocked from 1333 Hz to 1066 Hz.  Clearly there was no performance enhancement. 

     

    Though my experiment suggested that this may work, there is no guarantee that there may not be issues later on.  Another reason not to install higher speed RAM is that the higher the the speed, the more unstable the RAM may become and also the failure rate is increased.

    So it would work, but at the lower speed? I would have thought that using higher spec RAM at a lower speed would make it more, rather than less stable.

     

    The performance increase I would expect is not from the faster speed of the RAM, but from the increase from 4 to 8GB.

     

    So, in essence, should I give Will my 2x4GB SODIMMs, or should he purchase the 1066 SODIMMs?

    Your logic is valid but not necessarily correct.  Operating at a lower speed does not mitigate the design parameters that enable the higher speed for the given RAM chip.. 

     

    More RAM allows you to rum more applications simultaneously or the the real 'glutton' applications more efficiently (reducing the need to access the HDD as often).  The CPU governs the speed.

     

    Mac's have a reputation for selectivity regarding RAM.  The bottom line is get the RAM with the specifications for the given MBP which in this case is:  204-pin PC3-8500 (1066 MHz) DDR3 SO-DIMM (13" mid 2010 MBP).  The most reliable sources for Mac RAM are OWC and Crucial as mende1 said.

     

    As an aside, the 2010 13" MBP can now accept 16 GB RAM.  I have only seen OWC offer this option.

     

    Ciao.

    Oh, Crucial does not offer the 16GB option if you search by machine, and OWC doesn't seem to be available in the UK.

     

    http://www.crucial.com/uk/store/listmodule/DDR3/list.html

     

    In fact, they don't list 1066 8GB SODIMMs at all. Looking around, it seems you are right about OWC, as they have tested it, but I haven't found a UK supplier of the SODIMMs

    Oh, and for the topic, the 13" MBP is used for animation and video editing.

     

    Thoughts?

    Look, try it.  Generally speaking, as long as the type of memory called for is the same (which in this case it is), then speed is the next factor.  Faster memory in a slower designated system, as you said above, should work.  It's usually the other way around that it doesn't work well.  Technically speaking, the RAM should downclock itself and as it does that, even it's CL will change.  RAM is usually build to run "up to" the spec indicated on it, so there should be no reason why it shouldn't run at one level slower.

     

    Install it and see what happens.  If the system boots, go into System Information and make sure all the memory shows up.  If it does, then use the system intensively for a week.  If it's going to crash due to RAM instability, it'll do it within that timeframe... especially if you're cramming it full with video editing work and really working that new RAM.  Basically, you want to push the machine as hard as possible for at least a week.  If after that it's stable and it's still stable after 2-4 weeks, it's all good.

     

    BTW, forget OWC.  Aside from Apple, they're the next most expensive part anything for Macs.  For RAM and hard drives it's kind of a rip off in my opinion.

    Two points;

     

    If you have return privileges, I would try two 8 GB RAM chips with the afore mentioned specifications and see what happens.  Incompatible RAM will not destroy the MBP.  I personally would be interested in the result.  From a practical perspective, 8 GB RAM probably will do.  Note that adding a SSD will enhance performance more than adding 16 GB RAM.

     

    Regarding  animation and video editing, a 13" MBP is not the best option.  A 15" MBP would suit those needs better due to a faster quadcore CPU and the larger display.  In the notebook format a 17" MBP is the best option, but alas they are no longer in the product line.  I recently purchased a refurbished late 2011 17" MBP for that reason and simply I prefer large displays.

     

    Ciao.

    So, you'd rather introduce an SSD to a system with only 4GB of memory and think it'll allow you to do more work.  From a speed perspective of starting the OS and apps faster and doing anything hard drive related faster, yes, but in terms of being able to do more without swapping memory to HD constantly, no.  Ideally, no Mac these days should come with less than 8GB of memory, but Apple's too cheap for that.

     

    The memory he's got is free.  Install it and see what the result are.  You have nothing to lose.

    SwankPerFection, greetings;  Let me clarify the point.  A MBP with 8 GB RAM and a SSD will be more responsive than a MBP with with 16 GB RAM and a HDD.  This is based on bench tests using CPU intensive applications.  Having said that, it also would hold true with 4 GB RAM.

    Beg to differ. The above will hold only if the workflow is identical in both conditions. Memory/CPU boound tasks such as rendering, numerical computation, etc., will be no more enhanced by the SSD once the code and data has been loaded to memory. And not even the fastest SSD can outspeed RAM.

     

    But for most Real World scenarios,  the SSD will have an impact  beyond that of just the RAM.

    I do wish to thank you guys, regardless of whether this has resulted in a clear outcome.

     

    I think it is fair to assume that, putting my 'wrong' RAM modules and the slowest/cheapest SSD would, in fact, increase performance. However using the 'right' SODIMMs and a mid-range SSD would probably be considerably faster. And regardless, it would be more ideal to render video with more RAM, more cores and an independent GPU. This may become a reality in the near future, however the MBP shall still be needed for working on the road.

    Look, if your buddy is looking for a free upgrade, upping from 4 to 8GB at no cost is pretty much a no-brainer.  Hook your buddy up and see how he fairs.  If the memory was to work for him now, would you rather give it to him or would you rather it gather dust in your drawer?
