    That's all Prime95 large FFT?
    The -1 MCH ref is better than default?
    tRD usually boot and work or doesn't boot, but maybe on the edges it will just fail stress.
    It's my bed time, hopping to read good news in the morning.

    They don't seem to make you any good but worth trying.
    Not very likely at this FSB, but you may try changing MCH/CPU Clock skews up to 150 each.

    Thanks for the help Chike, I hope for some good news in the morning as well :P

    Yea they were all large FFT's since it freezes before small FFT's do (with that said, I haven't seen a small FFT freeze)
    In the BIOS, it will show "defaults", well it shows tRD as 11 so I might try that. Just tried the tRD 10 and -1 MCH Ref and got the Core 1&2 erroring out again. I'll play with CPU Ref's now.

    *EDIT*
    Downloaded the newest EasyTune and still locks up when I click set. Oh well.

    lol this is just hopeless. I gave up on 480 and went to 470 and that's not stable. I'm going to start yet all over again with 450MHz FSB and make sure it's plenty stable and increase tiny amounts. I just get too anxious... I want results in less than a few hours :(

    I thank Chike and lsdmeasap for their patience again.

    Use a old Easytune, here is the one I am currently using because I have the the same issue you mention with any of the latest ones and UD7

    Oh cool, thanks. That might help me not get as frustrated :) I would seriously almost pay to have someone come over and do this. I don't think I've been more frustrated with my computer.

    I'm sure I'm pretty stable at 450MHz FSB (heh, at least I'm stable at something) and with Easytune, I'll work my way up... again. I'm going to let this Prime95 run overnight just to make sure I have a 100% stable base then I'll post it so others can use it as well since I'm probably a bit high on the volts and very loose with the timings.

    I just gotta remember to calm down, take it easy and slow, and learn something along the way.
    I'll give you the rest of the night off lsdmeasap

    Well, I think I have good news and a little confusing news. The good: I'm pretty sure I'm 100% stable at 460MHz FSB and 3.68GHz (template below). I have been running OCCT Linpack for 4 hours 35 minutes and counting with no errors. The confusing news is that I ran Prime95 overnight with the same setup and I woke up and the computer was off. I checked the log and it had no errors and Windows didn't alert me that it was shut off improperly. Sleep is disabled so I don't know what happened. It ran for about 6-7 hours without errors so that combined with Linpack... I think it's stable. I did have to turn the volts down due to heat so I don't know how far I'll be able to go but I saw 78C on the NB and 76C on one of the cores as well. Maybe I'll run with this until I get a new CPU cooler and re-work the northbridge a bit.

    Comments and concerns about the template are welcome :)

    Wouldn't worry about 76c on the cores if it's during linpack test, but 78 on the NB is troubling, I don't think it should get anywhere near it.
    Is the NB HS getting very hot?

    Yea, I'm not too worried about it during Linpack but I'm at 460 and I would like to go higher and it would only get warmer so I had to kick the volts down. I can't tell about the HS getting hot since it's a bit cramped in my case:
    http://dl.dropbox.com/u/464376/websi...6/DSC05595.JPG

    Right now with the lower volts, I'm seeing 68-70 on the northbridge and 72 was the highest recorded on Real Temp so the voltage definitely helped and with that I'll go a a bit higher. When I get a new CPU cooler, I'll take off the NB heatsink, check the thermal paste and then attach another similar fan to it so it has better cooling. Right now that 1 fan is at 5v instead of 12v, bumping it up I'm sure would help but it's wired to the memory fans and at 12v the memory fans get too loud for my taste. In any event, it should be better after I work on it some more physically.

    Also, thanks lsdmeasap for EasyTune, it's nice to do the work inside Windows.
