I passed 1st battery of tests and continues. I'm pretty sure it will keep pass those test without anyerrors, after all memories there are 2x512MB samsung and for this machine I was choosing ram's recommended by the manufacturer this motherboard. Regarding nvidia, I don't like their binary policy but I may tell you that both intel 925XE machines can run indefinitely (for days even months until I reinstall new kernel) each with a lot of simultaneous openGL with nvidia on 2 monitors in dual head, dvb receiving over usb (here I mean USB 1.1 only) firewire traffic, SPDIF output, ethernet traffic on both interfaces and all that through enabled SMP, PREEMPT and PREEMPT BIG_KERNEL_LOCK and it is not going to crash. As soon as I enable EHCI there it comes. Otherwise I have option to use EHCI and don't use SMP but not them both.
