Memory allocation 132Mb

[ciprol]

New to Parallels Desktop and have just installed RC1 on my MacBook. The installation occurred when I had the base RAM amount (512M) and in the memory setting, Parallels recommended 132Mb for my Windows XP VM. Fair enough.

Now I've increased my MacBook to 2G of RAM, but Parallels continues to say that 132Mb is the maximum it recommend for my installation.

I've tried once to use a setting around 396 but Windows XP ran sluggishly. Not sure if there are other factors involved there. Irrespective, is parallels Desktop still thinking that I only have 512Mb of physical RAM? Anyone else seen this?

On a similar note, is there an optimal memory allocation for Windows XP VM under Parallels Desktop? I understand that Virtual PC used to run best at 256M allocation. Any more would actually deteriorate performance. That came out of a M$ engineer. Anything Parallels officially recommend here?

Thanks!

I woul drecommend that you just uninstall PD and reinstall, that should clear up you rmemory isues. Hopefully your VM images are in a directory other than where PD is installed.
Once you reinstall yuu can just reload the VMs you've created and you should be back in business.

in terms of how much RAM to allocate, I've found that the more the better the performance but I do believe that there is or used to be a limit ofaround 900meg. I use 900 for all my VM except Linux which whacks out the Linux images in PD if its more than 512megs.

HTH,

If you look in preferences under the Parallels menu, there's a memory tab. You need to bump that up. I also went to 2GB and made it around just under 1GB or something (I can't check at the moment) This allowed me to then configure the VM to just under 900MB and things have worked well. When I went more than that, overall system memory got a bit too low. Hope that solves it!

Thanks. That solved.

I have to say that there are a lot of configurations under Parallels. Still getting to know the program.
