Almost seems like it is Heat related, but that is not the case here. I take temps with my Laser while testing and after to see how hot the NB/Mosfets/SB etc are. 32C is the max I get on the NB for instance,(very good cooling), with about 28C idle.

Funny thing is that if I wait an hour or so, reboot and try the exact same tests again, they pass? Not looking for help just a statement. Just a quirk in the chipset I believe. Again, seems heat related but does not show as such.

Heh, think I sorted it out, it's my cpu, further degrading. Damn 45nm's.

I jacked up the Vtt to 1.25v (was at 1.20v) and bumped up the vcore one notch and now it's perfect. I just backed the vcore down one notch to where it was leaving the Vtt at 1.25v and I'm retesting. It's weird as my cpu hates any Vtt setting between 1.20v and 1.24v, but at 1.25 it seems to be fine.

I don't think it's the P45 chipset, although I had very odd behaviour from my P5Q-D, which is one of the reasons why I RMA'd it. I just wish my board could do higher than 666 MHz on the ram, it's pretty weak in that department.
