Is There a Way to Increase The V-RAM Above 256MB

Hi, I have had my mac mini for about 5 months, and in that time have also maxed out the ram (4GB). I was wondering if there is a way to force the amount of Video-RAM above 256MB. Is there any thing i can change in system preferences?

Is this a good question?

This model uses a GeForce 9400M that shares memory with the system. I have not found where that could be upgraded, but:

Officially, this model is capable of supporting 4 GB of RAM, but as first reported by MacminiColo, this model unofficially can use 8 GB of RAM after applying EFI Firmware Update 1.2. You might try that route.

Depends which OSX version you are running and the amount of system RAM installed. On a 2.3 i7 2012 Mini with 16Gb system RAM, 1536Mb of RAM is allocated to the Intel HD4000 graphics when running OSX 10.11, but only 768Mb when running OSX10.10.5

The Late 2012 mid-range Mini (2.3 i7) ships with 4Gb RAM and the Intel HD 4000 chipset, and allocates 256Mb to graphics I believe.

I have just upgraded the RAM to 16Gb (thanks OWC) and the System Report shows that currently 768Mb is allocated to graphics.

So adding physical VRAM, no; the machine allocating more RAM to graphics, yes, by adding system RAM.

Hope this helps. Will add an SSD to the second slot in the next week or so and the little mini should be purring along nicely.

Interestingly, my 2012 Mac Mini 2.3 i7 with 16Gb of RAM has increased memory allocated to VRAM when running El Cap 10.11.1

On About My Mac I note currently the Intel HD4000 graphics has 1536Mb allocated to it.

I understand El Cap shifts a lot of work to the GPU, so I guess this will improve performance. Certainly seems fast enough!

Even if your Mac mini is full ram there's no system option to ad more ram (vram) to the video card but that would be a nice feature.

'mayer' is fairly correct. When the using a mac with the GeForce 9400M GPU installed according to Apple:

"The NVIDIA GeForce 9400M allocates a base amount of 256 MB for video and boot processes at startup. For example, a MacBook Air (Late 2008) with 2 GB of RAM installed has 1.7 GB of memory available to Mac OS X and applications (2048-256=1792). Mac mini (Early 2009) computers with 1GB of memory share 128MB of main memory with the NVIDIA GeForce 9400M."

We have an A1283 (Mac Mini Early 2009) with 2GB of RAM installed. The video portion in the Graphics/Displays portion of System Profiler shows 256MB of VRAM allocated after startup.

ADDITION:

Just upgraded from 2GB to 4GB on the Mac Mini (macmini3,1). Took out the original 2x1GB Chips and replaced with 2x2GB DDR3 Chips.

Now there is a total of 4GB RAM with VRAM still at 256MB and now the available RAM for system is 3.75 GB.

It does speed it up somewhat.

Next upgrade: replace Fujitsu 160GB 5300RPM HDD with 8MB Cache to 160GB 2.5" Western Digital Scorpio Black 7200RPM SATA 3Gb/s 9.5mm Notebook Drive with 16MB Cache. We'll see if it makes a significant difference.

The video ram is a fixed amount that is a separate piece of ram from the main RAM. It comes with the video card/chip and cannot be upgraded unless you buy a new video card. I cant really understand what you mean by ‘maxing out the RAM’ please explain further

He's installed two 2GB PC3-8500 DDR3 SODIMMs and maxed out the RAM.

As Mayer refer to -The video ram is a fixed amount that is a separate piece of ram from the main RAM. It comes with the video card/(VIDEORAM) or V RAM for short this chip and cannot be upgraded unless you buy a new video card. The cost replacing V RAM depends speed model GPU but it is not effective to replace V RAM unless buy thousands of VRAM different speeds which is not cheap .The bios in these graphic cards -Customised mac only!! .A duo bios subset available older desktop mac MacPro pre 2013 Intel Model Only - AMD was ATI and NVIDIA card to keep older MacPro update till card no longer available if it can sourced...

In world two major players market fixed VRAM (AMD/ NVIDIA) non shared and shared memory with existing Desktop or Laptop Ram (Intel Graphics) no ram for graphics.

This is a video card that uses system memory because it doesn't have any integrated.

Apple has jumped around with different designs over the years. As such you need to reference a given system. Some use dedicated RAM others use the systems memory.
