Apr 14, 2013 9:17 AM in response to dhelix33by SwankPeRFection,You might want to add doing a complete shutdown on the system as #1 to that list. I've seen people put a system to sleep and then fry it when they install the memory because they weren't thinking.

Apr 14, 2013 9:24 AM in response to dhelix33by studyplenty,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.

Apr 14, 2013 12:41 PM in response to studyplentyby SwankPeRFection,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.

Apr 14, 2013 1:19 PM in response to SwankPeRFectionby dhelix33,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...

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

Aug 1, 2013 7:37 AM in response to iamlayneby Elliot Rodriguez,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.

Aug 1, 2013 3:58 PM in response to Elliot Rodriguezby Courcoul,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.
