Increasing your vRAM size to reduce related Crash Hangs/VRAM issues.

[Walt 178]

Here's a quick simple guide on increasing your vRAM size for your virtual machine in order to reduce related issues of crashing. Not all crashes are fixed by this.

 

Crash hangs, BSODS and Virtual memory errors can be fixed by this. Not always, but can be.

 

Go to your virtual machine folder which contains all your files for the VM to run. Default is:

C:\Users\Exiled\Documents\Virtual Machines

 

 

In this file, add this line to the bottom of it or update it if it is in your .vmx file already

 

svga.vramSize

 

All sizes are done in bits. So to increase your vramsize to 256mb

 

You would need to type:

 

svga.vramSize = 2048000000

 

then save and close.

 

 

 

Make sure your virtual machine is off before attempting this. Make a back up of your .vmx file before editing it.

 

Make sure you know what you are doing and if your video card cannot support to give 256mb to the VM it will not work and do nothing. This guide is for more tech savvy users. 

VMs usually have 64mb to start out with.

 

You can find out how many bits in are 64mb by typing:

"64 mb in bits" into google.

Can virtual machines utilize external video cards?

Or are you referring to the integrated graphics of some processors?

My GPU (GTX 980) reports 0-1% utilization even with multiple VMs running, it feels like all the work is done by the iGPU.

 

I'm also asking because I might be building a new PC soon and I'm wondering if I should go with a quadcore + igpu (such as the 6700K) vs a sixcore with no igpu (such as the 5820K)

 

Have you tested what kind of build works best for running multiple VMs?
