Can I increase the BIOS setting for the "onboard" video memory?

Currently the BIOS shows 8 MB allocated to video, in my HP Celeron D 340
machine. The machine has only onboad video.

The specs from HP's site read...

"Video graphics:

Integrated with up to 64 MB allocated video memory"

If I change the memory setting in the BIOS, will it change the
performance, and if so, how much should I increase the memory setting in
the BIOS.

The machine has 1 gig RAM. (The motherboard is an MSI MS-6577).

Thanks.

With 1 GB of RAM, chances are overwhelming that you will NOT miss
a piddling amount like 64 MB should you choose to allocate that
much to video.

As to whether or not allocating additional RAM to your video card
will do anything for your video performance, that depends
entirely on what you use your computer for.

Personally, since you have 1 GB of RAM to play with I would just
say that this is not worth spending any time dithering over:
just up your video RAM to 64 MB and be done with it. If you
only had 256 MB of RAM, this might be something worth thinking
about, but not when you've got 1 GB.

I certainly will change the setting to 64 MB. I guess no harm there.

I wonder why it was only set to 8 MB. The computer came with 512 MB RAM.

I also wonder if the onboard video processor would just grab RAM
automatically even if the BIOS setting was not changed above 8 MB. ...I
have no idea of how onboard video is supposed to work.

Thanks.

It was probably just the BIOS default and no one thought to
change it when the system was built.

By contrast, every system built around an nForce or nForce2
motherboard with IGP had a BIOS default of 32 MB.

It's possible that the OS, Win??, video driver can reallocate video memory.
Certainly 8MB is not enough video memory to run 1280x1024 at even 16-bit
color.

Amazingly enough, it's plenty for 24 bit color

1280 * 1024 * 24/8 = 3932160 bytes

Sure it is. I remember doing 1280x1024x24bpp once upon a time
with a 4 MB Matrox Millenium.

LOL, but these are the days of 512 mb graphics cards! My only
suggestion would be what does the graphics card manufacture suggest?

For example my Evga 6600 gt suggest to set the perfered bios memory
settings to 4mb for the aperature size. This is found on pg 13 of
their quick start guide under bios settings.

Yes this is a 128mb graphics card, it works fine as is but I know my
aperature size is maxed out maybe I will change it to factory
recommended 4 mb.

In a way it makes some sense, but I am not that knowledgeable to know
the whole reason.

Rthoreau

My bad, I forgot we were talking about onboard graphics, but it does
raise the question of why one manufacture suggests 4 mb aperature size.

I guess the real question is just how does the aperature size work in
modern bios'es? Is it a buffer, or does it allocate it to memory, where
exactly does it store it?

Everyone forgot that is for 2D graphics with only one buffer. For 3D graphic
accelerator card, you need two full buffers and one half size Z buffer. I
forgot the format but I think the factor is either 2.5 or 5 times of 2D
graphics needs.
