5x WoW and Vista 64

[Contagion]

You can use the PAE switch to get Vista 32 to address more than 4GB of memory.

The question is if the WoW code supports PAE mode.

Microsoft supports Physical Address Extension (PAE) memory in Microsoft Windows 2000, Windows XP, and Windows Server 2003 products:

Windows XP (all versions) 4 GB of physical RAM* (*Total physical address space is limited to 4 GB on these versions of Windows.)



Vista doesn't support PAE because it already has a 64bit mode. XP doesn't support > 4 GB even with PAE mode. Not sure what the point is then unless it helps overcome the 1G of RAM lost due to be being allocated for video devices.



All that said, the best option? Download the X64 Win7 RC and get 8G of RAM (or more if your motherboard and wallet support it). You'll have to upgrade to the real Win7 release when it comes out, but it's better than switching to Vista at this point.
