Hello! Today I upgraded the ram in my macbook pro 15 "late 2012 (i7 2.3 ghz) bringing it to 16GB. Ram is Samsung 1600MHz. Vram I have noticed, however, that the HD4000 is not increased to 768MB (as it should be 4gb ram = 386mb vram, 8gb ram = 512mb vram; 16gb = 768MB vram.) What can I do about this "problem" does anyone know anything? (sitema is the mountain lion aggornato latest version).
Thank you.
MacBook Pro, OS X Mountain Lion (10.8.2)
Hey evh92,
The VRAM dedicated to the integrated graphics card is not the same as the RAM you just upgraded, so upgrading to 16 GB of RAM will not change the VRAM dedicated to the HD 4000. Hope that helps!

But then as you increase the video memory? Because I've heard several times that, after an increase of RAM to the Mac, the video memory increases ...😕
Sorry about that, I was completely wrong. The integrated chipset does share memory from RAM. From what I was told there is no way to reallocate memory for the HD 4000 graphics, I may be misinformed on that too though... The article does mention for HD 3000 graphics chipsets, "8 GB of RAM, 512 MB allocated. Exception: 384 MB is allocated on 15-inch and 17-inch systems." and if I look at my 15" 2012 MBP I have 384 MB allocated with 8GB of RAM. I'm going to do some more research and if I find anything interesting out i'll post it here.
The video memory (Vram) on any Intel integrated graphics is dynamic meaning that the amount allocated is dependant on :
The amount of total memory installed in the machine ie 2Mb, 4Mb etc
The program being used and how graphically demanding it is.
Thus the machine will allocate anything from 64 Mb upto 768Mb, you as the user can not normally change this.
(This is the same for Windows machines with Intel graphics)

Hey all, I upgraded my Late 2012 Mac Mini's RAM to 16 GB. I noticed after the upgrade that my VRAM is now 1024 MB listed in system info and diagnostics. Just figured I'd share this.
Can you please share some pictures of your mac mini system info? Is it still recognizing the 1024Vram? Which brand was your ram?
Upgrade to Mavericks and it will allocate 1GB of RAM to the integrated Intel chipset for 1024MB of VRAM. With Mavericks compression of memory, Apple has allocated more RAM to VRAM.
Thanks a lot for the picture and the informations.
I would like to know if Mac Book Pro Laptop of 2011, (with cd drive) has the ability to increase the Video Memory, if so How??The 2011 models i have seen have only 384 Video memory. Need to ensure it has at least 1GB video memory. I need to run and install certain video software. Thank for help. Any suggestion is most welcome. . And how does one increase the video memory?
This video will help you to know how increase the video memory after increase your Ram memory. i have an early 2011 macbook pro 13.3'' A1278 intel core i5 2,3 Ghz with an integrated intel hd 3000 with 384MB shared OS X El capitan. Thanks to this video, i was able to increase to 1024MB of memory shared after increase my Ram memory to a 16GB 1333Mhz DDR3. Hope it will be hopeful for you. You have to disable the SIP before if u are using OSx Capitan, after finish you can enable it again. For info: Update OSx make video memory back to standard value. Good luck
