I just figured that dropping it @ 1.30V .... 11+ hours.
My old 955 needed 1.225V for CPU/NB @ 2600(Crosshair III). Unfortunately , Everest did not read the CPU/NB voltage at that time(no proof), so its up to you if you believe it or not
I'm finding with the large FTT test to be a complete crap shoot on the x4 955 BE time-wise. Time of stability seems to have no correlation to if it will pass the 24 hr mark. It seems to be more related to the size of the test. I had lower voltages that passed the large ftt test but wouldn't pass the 512k test (would pass large ftts but would fail about 6 hrs in on prime95 blend).
This is one of the reasons this chip is driving me insane. I would have thought the same as you if my x4 955 BE wasn't be finicky with the IMC voltage.
I thought the same as you between 1.25-1.35 v. I found instability started earlier with more voltage so tried lowering it but couldn't pass a 24 hr run. After going past 1.375 I found stability increased in length again. I'm at 1.4v and so far 11 hrs in.
Also found sometimes increasing CPU voltage helps too oddly.Edited by evilferret - 1/15/11 at 11:51am
