I have passed through a PCI-E graphic card to a VM with two cores and 2GB of RAM, all worked fine, but the problem is that

the VM turns very very slow when you set the RAM over 2GB

Iv tried to use 2.7GB to test if it's something related to 32/64bit problem, but the same, the VM became very slow (about 5 min to get into windows 7)

then I have reloaded the guest, the problem remains

then I have reloaded the host, the problem remains

weird, and I am not able to find any information about this, some ideas?
