OK, small FFT is the main test if you are running solely a cpu overclock
Large FFT is the main test to check you cooling/max temps
Blend is the test it all test lol, it's the one to make you cry
looking at your settings I would say that your vcore is too low for 3.6GHz, I need 1.3v in the bios which equates to 1.264v idle, 1.216 load.
I've never bothered to look for stress.txt, I have no idea where it resides, I looked for it in the P95 directory, nada, I tried help but it failed to load, lol
EDIT: at 400MHz FSB you're running your memory at 1:1 yes?? so at present you're only overclocking your cpu, yes? (just trying to eliminate variables)
EDIT2: 1.1375??? = "1.136 to 1.152" ???, mate, if your running 3.6GHz with those voltages you're doing real well
