I'm not sure what is changing it but I will keep a daily eye on it for awhile. I also set it at 20% as a compromise
I also have my swap file set at min & max @ 4gig. I just replaced the motherboard (DFI Lanparty Ultra-d) and am trying to get it tweaked out after a fresh install of Win 7 Premium 32 bit.
I do have 4 gig of dual channel ram (3 usable).
Some of the hardware just doesn't like the 64 bit version.
It would be nice to be able to lock down the system restore. I was just wondering if I was missing some reg setting or something.
