Thx. I always lock it down so it cannot resize itself all the time, but I think I set the min to what the max was at the time, 1536 as I recall. Either way memory usage hasn't been a problem at all, I kinda question whether a couple of these guys have even tried the OS or are just repeating something they read about 64bit OSs hogging resources.
An interesting advantage to having a dual+ boot setup is that you can use one to repair the other. For instance I went a bit too far with an OC on XP32 shortly after I set this system up and corrupted the registry, no boot, no safe mode...nada. Ordinarily I'd boot BartPE, go in and restore a backup copy of the hive, or at worst restore the original. Unfortunately for reasons I haven't yet uncovered BartPE hates this system and will not load on it. However I was able to do the same thing from within XP64 that I would usually use Bart for. Saved me a reinstall since I hadn't created any backups or ASRs yet. Just a small extra I guess.
