Anyone installed Komputerbay 16GB (2x 8GB) DDR3 PC3-12800 1600MHz RAM on their MBP?

So Intel is lying and the processor does not support the RAM that it is currently running at 1600MHz?

I guess it's easier to just type without trying - please don't waste our time though, this is a legitimate question with an answer that's not yet been reached.

You don't have it. Depart.

Nobody (except you) is talking about Intel, in the OP's Mac the ram will run at bus speed, whatever you think.

The OP gives no specifics, you're right, but having been down his exact path, I can completely understand him, and he seems to agree.

You, on the otherhand, are demonstrably wrong, yet continue to waste our time.

What do you mean, who's talking about Intel? Intel makes the component in the computer that needs to interface with the RAM that we are discussing. What else would we be talking about? Bus speeds?

Link me to something that demonstrates that my and the OP's Intel Core i7 2720QM or 2820QM will downclock 1600MHz RAM to 1333MHz.

I'm here.

I have been following this discussion for some time. Looks like no one knows much about this memory "Komputerbay" sold by Amazon.

I have been using this memory in several of my company computers for the past year and I have never had a problem with it.

I have three (3) of my computers (all HP's with the 8GB (2 x 4GB) DDR DIMM (240 Pin) 1333 MHz PC3 Sims and another four (4) with the 16GB (4 x 4GB) DDR DIMM (240 Pin) 1333 MHz PC3 Sims.

I purchased it the first time because it was so cheap from Amazon and because to this date Amazon has had a very good name for me. Any questions or problems I have ever had with one of their sellers they have taken care of at once.

I put the first memory in a older computer that I was going to get rid of. But thought I would up grade it with cheap memory just to see if I could get a little more time out of it. I have been using that computer now for 17 months since I upgraded the memory and the thing is still working perfectly.

In December 2010, I upgraded the rest of my computers because of the good luck I had with the first set and all of my computers have been running like new with the extra memory I added. It has actually saved me thousands of dollars because I have not upgraded my computers as I normally do about every 3 years.

After making my last post I thought of something that may be of a problem to some of you that or not better then average or experts in the computer field. I do not claim to be a expert, but I have been building my own computers for more then 20 years.

Some of you should question your operating system before you go out and buy new memory. It is very important that you know if you have a 32 bit or 64 bit operating system.

The following is something everyone should know before they go out and purchase memory, mayby to find out it will not work even when your mother board directions said it will work. This is something that every computer builder knows or he/she will not be in business very long:

How much memory your Windows OS will recognize depends on which version of Windows you are running.

32-bit versions of Windows will see (and utilize) only 3GB or 3.5GB. To utilize more memory, install a 64-bit version of your OS

People that is directly from the book.

As some of you may have noticed my posts were not about a MAC. I was only using the reference of my computers in regard to the memory from Komputerbay sold through Amazon. The original question was Does anyone know about it and is it any good.

@Csound1:

You've really got to go out and do a bit more research before posting again on something that you obviously are not quite up to actual speed on -- as in : what is the actualy compatible memory clock speeds for any of the i7 Quad-Core machines, (including Apple's) vs. what is post by Apple themselves as being their "officially" recognized compatiblility with all of their i7 Apple's machines.

Turns out that all i7 Quad-Core Intel motherboard can handle memory clock speeds of up to 1800Mhz without having really any problems. And though the native Bus speeds of the newest i7 Quad-core Mac is officially listed by Apple as running at only 1333Mhz, they can and will easily upclock themselves to a even higher base bus frequency - if, or when it is correctly paired with compatible, higher clocked memery modules of up to 1867MHz. There have been some reports of minor system, and/or application instability at the highest 1867MHz clock, but there has been little to no reports of instability, or incompatibily issues when utilizing the PC3 12800 (1667MHz) memory modules in any i7 quad-core based computers right now -- and that is also certainly true for any of Apple's current i7 QC line-up.

I've been very successfully using a pair of Kingston's 4GB (2x4GB) PC3 12800 1667Mhz Hyper-X SODIMM memory modules in my i7 QC Mac Mini Server since it was first accquired last October. I also custom installed a Crucial 256 M4 SSD in the primary HD slot as well. For about a month or so after that, I singlehandedly held the highest Mac Mini Geekbench score ever posted at 9857. It has since been slightly surpassed by a couple of folks who have either upgraded to the 2x8GB modules, also running at 1667MHz, or have 2x4GB chips running at the highest 1867MHz speeds possible.

And as can be clearly seen and accurately measure by these Geekbench scores, the higher clocked memory chips are indeed running at their full base clock speeds - which are very dramatically boosting the overall Mac Mini's systems perfomance scores - especially in regards to the more memory intensive applications and tasks like Video compression or image batch processing..etc.

So, in short, if anyone is interested in getting the very best performance that's currently possible out of your current i7QC Mac, then run, don't walk , at buying your own higher clocked SODIMM memory modules - if your budget allows. I'm now very nicely running my Mac Mini Server on 16GB's (2x8GB's) of PC12800 @ 1667MHz without so much as a hick-up, and ding so at least 20-30% faster than Apple's "official" advetised base 1333MHz speeds

And one more note on utilixzing these higher clocked chips is your i7QC Mac: make sure that you ahve installed all necessary system updates (at least 10.7.2), and all firmware/hardware updated proir to installing them. Some have reported compatibility issues if they are installed immediately right after first buying a new i7QC computer - since the earlier i7 QC Mqacs came with only the base 10.7 Lion install, and also didn't have all of the essential firmware updated installed (like the Thunderbolt one) and such.

Chuckedm: I don't think anyone doubts that Komputerbay RAM will work in some, probably many, machines. But the thrust of the original question was whether a particular Komputerbay RAM kit was a good choice for someone with a MacBook Pro. Your own experience may or may not have any bearing on that. It is true, as I think someone has mentioned above, that MBPs can be pretty finicky about RAM, and that out-of-spec RAM of various brands sometimes doesn't work in them even when by rights it ought to.

stevielee:

You are 100% correct except in that PC12800 is 1600MHz, not 1667.

Otherwise, perfect.

My bad!

I mistakenly conflated the extra 67MHz from the higher PC3 15000 1867MHz memory clock speeds with it's lower clocked sibling PC3 12800 running (as you correcly stated) @ 1600MHz. Thanks for picking up on my error there. Must try and proof read my posts more thoroughly in the future becuase I see at least a dozen more typos in that posting above. Big fumbling digits - pared with tinykeyboard devices are my posting's ultimate undoing.

Cheers!

I'll keep it simple for you, I recommend using ONLY the parts that Apple recommends for their machines, even though you are right I couldn't give a ****, if Apple says 'use this' I second that, are we finally clear?

mate, this is a discussion, we share useful information here, so if you are not really helpful then please just excuse yourself, because everyone here apart from you is being very nice and helpful

I am not the one suggesting using parts that are not recommended by Apple, who's choices so far have turned out to work well. Do what you like, I will recommend what I choose.

@Csound1

Look, I'll also keep it "real simple" in addressing your original post stating incorrectly that if one were to install the higher clocked PC3 12800 memory chip running at 1600MHz, or a PC3 15000 module running at an even higher clock of 1867MHz, that the systems bus would still run ONLY at the base 1333MHz clock - because, according to your limited "apple recommended" ONLY information on this subject, you authoritatively asserted that any of Apple's i7 QC's computers with a base bus frequency of 1333MHz cannot possibly exceed this speed to match the higher clock speeds of the 1600MHz, and 1867MHz memory modules. Aside from your unquestioning adherance and complete reverence to Apple's officially recommended seal of equipment approval defense subterfuge, I tries to hopefully provide the OP (and any others here who might also be interested in the subject at hand) with technicaly relevant and experientially accurate information regarding the upgrading of memory in any i7 QC Apple computer right now -- so that they might also enjoy beinb able too more fully utilizing their machines to thier more optimal operational potential.

And whether you could give a flying @##$% if the information I provided is correct, or official approved, or sanctioned by Apple themselves -- is besides the point, because this thread is not really about what you personally give a S%@t about, but more what everyone else may give a S%@t about.

Best to you regardless!
