2012 MacBook Pro 16GB RAM Upgrade

Why did you bump this year-old thread without any new information?

Anyway, I wanted to let you know that you're wrong about 1600Mhz RAM, it was supported going back to the first Sandy Bridge 15" Macs.

OK

I still like the new MacBook with 16GB upgrade - take care...

Sandy Bridge maxes out at 1333Mhz, so the 1600 will downclock itself. Most novice users will install 1600 and wonder why they don't see the full speed, so your post could be misleading to some. Either way, dhelix didn't say it wasn't supported. He/She said that the memory bandwidth was increased under Ivy to 1600 support, which is correct.

Thank you sir. I upgraded the new model 2012 MacBook Pro 15 I bought last week to 16GB - clocking @ 1600Mhz with the quad-core Intel 2.6 GHz "Ivy Bridge" i7 processor installed.

I did upgrade my 2011 iMac 27 with 16GB of RAM - clocking @ 1333Mhz (which is the the maximum speed with the Intel 2.7 GHz "Sandy Bridge" i5 processor installed in my machine). Not sure if the same year model iMac with an i7 Sandy Bridge can push 1600 MHz of RAM though.

I was looking at comments about a MacBook Pro 15 RAM upgrade - thought this was a current thread - that is why I posted here...

SwankPeRFection -

The mid- 2011 iMac 27 with i7 Sandy Bridge maxes out at 1333 HMz for RAM - just as you correctly indicated.

Will 16GB have a positive impact on the allocated memory for the HD4000 in a 13.3 Summer 2012?

I use boot camp to play games on Windows, and I believe it will improve, but I want to make sure before I sink the cash into it.

Thanks.

Positive, yes. Given there will be lots of RAM, more can be spared for the graphics subsystem. But since the GPU will still have to be wrangling with the CPU for access to the RAM pool, don't expect performance equalling that of a 15" model that has VRAM separate and dedicated to the task.

I do not know when you posted this question, I just found it today 12/10/2016 and see other responded. Yes you can install 12 GB Upgrade but you have to have the right ones, the 1333 MHz make your "BeachBall" frequently. The right ones are:

16GB Kit eRAM Memory (2 x 8GB) 204 Pin DDR3-1600 PC3-12800 1024x64 CL11 1.5V SODIMM's

"Data Memory Systems" is a good source and has the best prices. I use them for 20 years without any problems ever.
