Video driver crashes when multi-boxing

[declensions]

Hi guys, hoping to get some good help here.

I am multiboxing 10 diablo 3 clients using VMware, with 1 VM per client, all running on the lowest settings possible.

The problem I am running into is that every few hours my GPU driver will crash, and all of the VM screens will go black. I end up having to restart all the VM's because I can't do anything when the screen is black. (Just the VM screens are black)

I have tried 2 different GPU's, an nvidia GTX 460 and a radeon 5850 (both 1gb) and get the same problem.
I did not have this problem when I was running the bots on the Intel HD 4000 graphics (when I did not have a dedicated GPU). I wanted to take stress off the CPU so I installed a dedicated GPU
I think it may be a ram issue, since the intel HD 4000 shares the system's ram. Does having multiple VM guests count as having multiple displays?
Will I be able to fix this issue if I upgrade to a 2gb video card?

I need to make this work using VMware (in otherwords, 1 ip per client) so please do not suggest that I use isboxer unless there is a way to do the same. Your help is greatly appreciated.

My system specs:

gigabyte z77
i7 3770k (not overclocked)
OCZ vertex 4 ssd (120gb)
32 GB ram 1333
xfx radeon 5850 1GB
rosewill 650w PSU

Maybe the graphic card is becoming too hot after long sessions of playing ? I had the same problem with my 5850 before I finally noticed one fan had stopped working...

Intel's Ivy Bridge means CPU + GPU so there's no reason why using the HD 4000 would decrease CPU performances, except it may become a bit hotter and use the system's ram.

Odd, isn't the max number of party members 4?

I'm not using them in parties.


I don't think heat is the issue. It sometimes happens within 30 min of rebooting my comp. This computer is for dedicated botting, I'm not doing anything else on it. (no browsers open, bare minimum programs installed).

I just don't want to use the Intel GPU in order to prolong its life (call it paranoia), plus the intel HD 4000 does not run the clients that well after I open more than 5 VM with the game running it starts to get choppy.

And the truth is revealed! We're not going to help you bot. Good-bye.
