Same here, I used E8400 the temps on Xeon E3110 are way too high when dual prime for ten minutes then E3110 reset it self when temp hit 91c. I never had a promblems with E8400. The damn chip behave differently it idle at 48c then at Load increases by 4 factors in seconds..... I though these Cpus are the same? Xeon chip are in fact superior processor chip (server) What are the thermal Threshold on Xeon E3110? The E8400 @ 72c.......I'm really stumped on the Xeon
