Tell me if anyone finds this strange.. I recently upgraded my Logic machine to: Asus P4C800 deluxe, 512MEG DDR400 (Kingston) x 4, P4 3.0ghzE (1 meg cache). This is the model with the firewirse, gigalan, SATA, RAID etc.. I have a SATA drive for boot, hyperthreading is on etc etc.. this thing is just blazing. However, in logic I sometimes get "Out of memory" Errors.. ! Weird! Other parts in the machine: Layla20, UAD1, Matrox P750 Triple Head, WinXP Home. I had no issues on my athlon1800. Any Ideas? Neil
