    500x7.5 is nice. You should be able to go 500x8.

    On the subject of NB temp, I'm not calling you a liar here, but your definition of hot must be really off, or extremely different compared to mine. You don't expect the metal to be cold to the touch? To me hot is something I can't bare to touch for more than a couple of seconds without having to take my hand away (eg DDR-500 SDRAM @ 2.85V), and too warm is something that gets uncomfortable after 15-20 sec.

    Ive run at 486FSB with 1.5v MCH and I could hold my hand on the heatsink all day long.

    Well, yesterday I only could briefly touch the heatsink. I guess anything over 2s would hurt.

    I'm runing Orthos large FFT now on a 1.5 MCH Core. I'll give it 30 mins to heat everything up, then see how hot mine is. Ambient is 23c.

    Well, HWmonitor says system temp 46, CPU around 80. The case is opened, because the outtake fan on top of it isn't working too well for the CPU - I have to move it back to the rear side. Or might just buy another one and blow the hot air out with two fans:D

    Ouch, that is pretty hot. Does RealTemp or CoreTemp and or Everest Verify that your CPU is 80C?

    If so, you need to back way off, because if your CPU is 80C then your cores are likely 90+

    Well, it's been that way for 18 or so hours, and no problem.
    Uhm, when I closed the case yesterday thinking the change of outtake fan would improve the situation, I freaked out a little, because the temperature reported was at 95 degrees That looked seriously bad.
    It is 78-80 indeed, this HWMonitor utility is really accurate (comes from same guys as CPU-Z I think; same site at least). I will tune VCORE further down when I am finished testing. So far there were no problems really.

    23 hours table - custom test. 2048-4096FTT, memory to use, all available

    shall I test more and differently? like in-place large and even blend as well?

    You won't have any initial problems. You could run your CPU with core temps of 95c for 24 hours witout issue. It's long term damage that's the problem. At 95c, the CPU wouldn't have a very long life. You could well end up with a dead component in a matter of months.

    Use RealTemp for CPU temperature monitoring. IMO, CPU socket sensors on motherboards are as useful as a chocolate fire-guard.

    As for stability, Prime Blend runs both small and large FFT's alternately. If it's 24 hour Prime stable, it's solid enough to be called generally stable.

    Consider a new CPU cooler (Thermalright Ultra 120 eXtreme, Noctua, Scythe Kama Angle etc) if you're getting more than 65-70c using Prime (measured in RealTemp). Your current one simply isn't up to the job if temps are that high on 4GHz with such a relatively low voltage. Also consider maybe a new case or a complete overhaul of current case fans, wiring etc to improve air flow. You should as always have a minimum of one 120mm front set to intake, a 120mm rear as extraction, and any top fans you have should also be set to extract. It's most likely your sky high case temps that are effecting both CPU temp and causing you to have a hot running NB.

    Dude. I repeat. The CPU is passively cooled. There is no fan on it. It actually is excellent cooler if it's able to keep the CPU going overvoltaged and being tortured by Prime95 :) In normal situations the temperature is around 40 in idle. Under 70 in heavy load. It's Thermalright HR series something, can't remember exact model. In fact one generation newer than U120-e, which I did own as well.
    I can't possibly get better case than my Antec 182 :P
    All I need to do is to work on the airflow. For now I attached an extra fan blowing roughly on the CPU.

    Art, I run 64bit Windows 7 and of course I do have 64bit version of HWMonitor. I know what I am doing, at least software-wise :D
