Mac Mini with 2GB of Ram - VRAM Problem

Hi,
I have bought a macmini with 2GB of ram, the system has arrived pre-installed and the "Sistem Profiler", in the section Grafic/Monitor it brought back 256 MB of VRAM (Shared memory). In fact I succeeded to play the Full HD video perfectly. 7 days ago I have re-install the operating system, to the end of the installation was not possible to visualize the Full HD video format. I have controlled the "Sistem Profiler", the VRAM was set to 64MB. How I can bring back the system VRAM (Shared memory) values to 256MB?

Help Me Thanks
Stefano

Sorry for my english 😟

The amount of RAM used by the video card is not preset at a specific amount...it goes up and down depending on how much video RAM is required by the specific program(s) you are running. There is nothing wrong with your computer.

Sorry, Do you know why the sistem not work fine with Video Full FD after the O.S. Re-Istallation?

Why the O.S. factory installation report 256MB of VRAM?

Thanks
Stefano

As I said before, the amount of memory given to the video card goes up and down. What the System Profiler reports will vary depending upon how much has been allocated at that moment. Stop worrying, everything is fine.

Is this fact true also on the 32MB Vram Mac Mini? I currently have 256MB Ram installes, and the unit is brutally slow, always has been. Wondering if after I install the 1GB Crucial Ram module I've just ordered, will the general computer operation improve significantly?

yes, a RAM upgrade will certainly speed your computer up immensely, especially if you have only 256mb right now.

No, on the G4 minis, the video sub-system was an ATI device with dedicated VRAM which was fixed at 32Mb. The only exception were the later units which had 64Mb VRAM. Either way, the amount of video memory did not vary by demand or use.

Wondering if after I install the 1GB Crucial Ram module I've just ordered, will the general computer operation improve significantly?

Yes, VERY significantly. It won't help video memory limitations which may be evident in games etc, but the system should change from being slow and sluggish to being smooth and fast with the added memory.
