Well, I found something new to and get the blood flowing again.

VirtualBox is a very low overhead virtual machine that runs anything but this is only for Ubuntu folks. It loads quickly, no need for rebooting either when installing or uninstalling. It is very quirky for me but it's working now after a few days of problems with the client locking up.

At this point the only tips that I can give is to make sure that 4 procs are chosen, 800MB of RAM, 5GB of HDD and bridged networking selected, oh and don't forget to mount the CD/DVD drive to install Ubuntu.

Of course this is for quad users only as I haven't tried it on my X2 dual yet, if it would work at all. One other thing if you're running a GPU2 client then make sure you set VBox'es affinity to first three cores and set the GPU to the last one. There is a command to set GPU to auto use the last or any other core, but I have to find it again.

The PPD increase is quite substantial, from 2K with VMWare to 2.6K with VBox. A decent gain if it works.

Well, I just got this going properly I believe, though time will obviously take its toll if I got it wrong again! I'm getting 7/8 min./TPF giving the VM all 4 cores ! The GPU's are set to low priority and the VB is set to idle. Oh, I gave the virtual machine 800MB. I'll do the math here and it simply works out to ~4K PPD!:shocked: Erm, call it double?

Here's a screenie, my quad is not OC'd either. I just hope it's doing good science, not like that driver I posted about last spring which was found to be defective at the least.
