This is the same 45nm processor bug that seems to be an issue with this board and related ones. Intel needs to fix it, but since these are "obsolete" products, I doubt they ever will. The board has these issues, not matter what 45nm processor is used. With the older 65nm types, everything works correctly. It is important to point out that the system is totally stable while running the 45nm CPU's, it just has the issues reported below:
1. The board will not do a warm restart, even just getting in and out of BIOS after a save settings, just hangs.
2. The CPU temperature is always reported at 102 at bootup, it then increments as it gets hotter, nevertheless, the individual cores are always some 70 degrees cooler according to programs like Hardware Monitor. I've duplicated this error with 4 45nm processors (E8600, Q8400, E7600, E8500.
3. Fan always runs at Full speed.
This is like toyota refusing to acknowledge their sudden acceleration issues, but of course no on dies here if their computer has these issues.
I am having the same problem its a shame that intel wont step up to the plate and admitt there is a problem. I for one am done with them. The customer support I have received through this process has been aweful. I am going to be useing AMD from now on. What a joke i though intel was better than this.
