[dgaschk]

Has anyone tried disabling these settings:

 

A760G M2+ BIOS Manual

Internal Graphics Mode

This item allows you to select the memory mode used for internal graphics device. Options: UMA (Default) / Disable

UMA FrameBuffer Size

This item allows you to choose the UMA frame buffer size for internal graphics . Options: Auto (Default) / 32M / 64M /128M / 256M / 512M / Disabled

 

I hate to think that 1/8 of my RAM is being wasted by a video buffer.

The UMA frame buffer steals about 200M of RAM in its default configuration.

 

UMA FrameBuffer Size set to default (auto):

root@192:/mnt# free -m
            total       used       free     shared    buffers     cached
Mem:          1770       1729         41          0        241       1349
-/+ buffers/cache:        139       1631
Swap:            0          0          0
root@192:/mnt# 

 

After setting UMA FrameBuffer Size to 32M:

root@192:~# free -m
            total       used       free     shared    buffers     cached
Mem:          1993        382       1610          0          3        311
-/+ buffers/cache:         68       1924
Swap:            0          0          0
root@192:~# 

 

Note the total increases by 223M.

 

This setting should go in the wiki under http://lime-technology.com/wiki/index.php?title=Hardware_Compatibility#First_Time_Configuration.

Great find.  I need to check mine on my older server.  It only has 512 Meg of ram and a little more available to it sure would not hurt.

I'll confirm this when I get a chance, then add it to the wiki.  Or, if you are impatient, you can add it yourself
