Topic: How does dedicated video memory work?

You have an ATI Mobility Radeon HD 4650 Graphics in there

So no, you have dedicated video memory built into the card. You have all 4 gigs of ram available since you are running Win7 64-bit, minus whatever it uses for system processes. So I would guess you have probably 3.5 gigs or so.
 
 
ok so how would i upgrade the video memory, i know where the RAM is, where would the video RAM be? on the video card?
 
The only practical way to increase video memory is to replace the entire video card.
 
Why do you think you need to upgrade the Video RAM?

If you are sweating this memory usage issue from your other post - then you are wasting your time in worrying. There is nothing WRONG with your system.
 
One of the reasons i bought this machine is because of the ability to do these upgrades. I realize it meets the required epecs right now, but for what its going to cost might as well max it... i figure it will only help... it says that video memory can handle up to 2GB... was just wondering how to go about it and though i'd run by the three wise men... :)
 
That's what kind of made me wonder.
Every time I've seen "up to xxx mb video memory" its meant shared memory.
 
djrasza,

You are missing the point here and in your other thread. Virtual DJ DOES NOT load your video in to video RAM. Video RAM is used for real time processing of video data - the rendering of graphics apps - in this case Virtual DJ, your MPG or MP4 video and any video effects/transitions you use!

Music and video are loaded in to RAM - your 4Gb. Now Virtual DJ itself has a very small memory footprint, this means you should have plenty spare for loading your audio and/or video. However, as cstoll has pointed out here (and in the other thread) it is your RAM not VIDEO RAM that is at issue.

My gig machine has minimal background processes running, no anti-virus, no "system tray" utilities, etc, etc. All of which pull on your main system resources - especially memory.

The first thing I would do is download and install GameBooster (http://www.iobit.com/gamebooster.html). This is one utility that WILL help. Gamebooster will shutdown any unecessary applications/processes safely, and then restart them when required. In fact the latest GameBooster can be set up to launch itself, shutdown services and then spawn an application (like Virtual DJ), then when you quit VDJ it will restore them.

Try it, then recreate the problem and see if its solved. If it is you will know it is because of uneccesary apps and processes running - something Rick refers to as "bloatware".

You then have a number of options:

1. Continue to use Gamebooster - I did until got my new gig machine ;-)
2. Uninstall the bloatware - but if your machine is not exclusively for DJing this might be in issue
3. If 2 applies, create a new partition on the hard drive, install Win7 again and use dual boot (this is what I do)

With 3, your gig partition will only have what you need installed. No e-mail, no A/V, etc. Just audio/controller drivers and VDJ! Simples!

Yes I do go online with my gig partition, but unless you are visitng dodgy web sites, opening unsafe e-mails then you should not need A/V for the amount of time you use it.

Now if the problem doesn't go away, your issue is likely to be a duff RAM chip which you can replace.

Hope this helps,

Roy

Ok so once it maxes out on the 1GB in the video card it will borrow from RAM up to 1GB to make 2GB overall...

i figured i wanted to upgrade to 8GB of ram anyways and while I was at it look into upgrading the video RAM... I knew i was asking the right people... thank you all :)
