As you said in the comments : Memtest is failing Apple Hardware Test indicates a possible memory failure This a clearly a bad indicator for your memory. The fact that a premium reseller is not taking your MacBook Pro for some obscure reasons would make me call a huge bulls**t. They have to take if it's defective !

I just installed 16gigs 1600mhz ram in a 2011 17 inch MacBook pro i7 2.2 and it's working great and is running at 1600mhz in the system report.

"Web Content Process" = "Tab" is a wrong assumption. A Web Content process can hold more than one tab. Depending on the implementation details of Safari, it might be possible that after closing the last Tab related to a particular Web Content Process it does not automatically mean to close that Web Content Process. It might be feasible for Safari to keep ...

My macbook had this issue before the 10.10 update, and after the update, the issue re-appeared. I just had to redo the procedure and it works again.tried it on 10.10, and it appears to work.

You ideally want both banks the same, this will allow interleaving which almost doubles the memory access speed. In computing, interleaved memory is a design made to compensate for the relatively slow speed of dynamic random-access memory (DRAM) or core memory, by spreading memory addresses evenly across memory banks. That way, contiguous memory reads ...

Given your budget (512GB SSD is quite expensive) I'd buy 8GB RAM + 256SSD and keep the 500GB HDD as a storage volume instead of the super drive. Depending on your country, it'll cost you around 200$ which is less expensive than a 500SSD and will bring you a lot of speed.

The brand shouldn't really matter. I have G Skill in mine with no problems. The stock was Samsung. The trouble with that specific model is that it doesn't clock down faster RAM properly thanks to some hardware bug with the Nvidia chipset. It's very important to only use 1066 MHz DDR3 with this model (you can usually get away with faster on other models). I ...

http://www.crucial.com has an app you can download to tell you which you need. Kingston & Corsair have drill-down selectors, but Crucial's is far easier.

1) RAM Upgrade As far as I'm aware, the laptop cannot be upgraded beyond 8GB. This is due to restrictions by the CPU and chipset architecture in that particular model. Unless you are a real power user who does lots of video editing or likes to have a lot of applications open at a single given point in time, 8GB should be perfectly fine. DDR4 ram is NOT ...

Clearly you should test your RAM Using the Apple tool for that To launch the hardware tests, boot your Mac with Option-D held down immediately after you hear the boot chimes, and the tests will download from Apple's servers. Using 3d party tools for that: MemTest for Mac OS X Tests your RAM

I think I had something like that happen to me at one point. Try taking all the ram out, blow out the memory slots carefully and put in one memory stick at a time and see if you get any issues.

Remove all RAM and reseat it. Do not reinstall the upgrade until you can determine the cause of the problem. Unfortunately, you may have physically damaged something during the memory upgrade. Also, just for kicks, did you try zapping the PRAM? I've never seen this have an effect on any of my machines but it's worth a try.

Perhaps the RAM simply became loose. You said it worked in another computer. Try putting it back in the original and make sure it is all the way in.

Sounds like your Logic (mother) board is done. You should see your RAM in the About this Mac. Try resenting the SMC and the EFI.

I chose the 4GB version and used the extra $$$ for more storage. I replace my laptop every year or every other year (Apple's computers hold their value and I usually resell them for 75% to 80% of what I originally paid). So if the 4GB RAM became limiting, I would just deal with it until the following year.

The memory you are talking about (also called RAM) does not "store". It only "temporary" stores. It is used for when computer is running to shuffle stuff around getting it from your hard disk (memory) and putting it back to it pending what you are doing. It does not stores anything permanently. Your files are stored on your hard disk. So go ahead and ...

Battery life is heavily dependent upon how you use the system. Things such as leaving screen brightness at maximum can have significant effect on how quickly power is drained from a charged battery. Applications such as running guest operating systems inside of a virtual machine can be I/O- and CPU-intensive tasks that will also reduce the longevity of a ...

To get a better look at your power consumption: Open the Activity Monitor in your Utility folder. Click on the Energy Tab. Look how much power is Each application consuming, and how much over time. Also look for "app nap" capability (application will go to sleep if not used)

Mountian Lion uses 2GB RAM, Mavericks 4GB. Windows 7 2GB... I don't want to know what the new Yosemite is going to gobble (especially a bad move of Apple soldering RAM t logic board in new MacBooks... the idea of plug-in chips in soldered chip holders would have been a better solution if RAM cards were omitted), and avoiding it because of this issue and ...

The mid-2011 iMac uses 4 - 204-pin PC3-10600 (1333 MHz) DDR3 SO-DIMM, so it seems that you've purchased the correct memory. The most likely cause of the problems you're seeing are improperly inserted- or faulty RAM. It can help to blow out the memory slots with compressed air and ensure that the RAM does not have grease or grime on any of the contacts prior ...

Your question seems to have invalid data. There is no A1287 MBP model. There are A1286, A1297, A1278 and A1286. Would you please clarify? I would be happy to help with the correct information. (There are others, but those are the closest IDs to what you wrote.) MacBook Pro A1278 configurations are as follows: 13" Mid-2009 Max 8 GB RAM PC3-8500 1066 MHz ...

I have here two helpful Links for you: Apple Support Serial Number & Apple Support Memory Upgrade I don't have experience with this memory, but i think it should work ;) But please use the provided Links and double check everything. I don't know how it is in Jp but in Europe you can send the RAM back to Amazon if it does not work. "Normally" a wrong ...
