    Ya, sorry about the confusion on the settings I gave. Looks like I was sleeping at the wheel!! Sorry man!

    Passing Memtest sounds good, looks like that part of things is ok for now.

    Your cores failing means you need more vcore of course, are temps ok enough under load to raise the Vcore? If so raise this a few notches and if you still fail try a few more notches. Then if you still are failing post back your failed settings.

    thing is before OC'ing, my average temp ranges between 46-51 and on full load its around 57-63. those temps seem to be a little higher than expected but i am using an aftermarket heat sink (Tuniq). i'll raise the Vcore higher and report back my results.

    Thanks

    Hmm ya that is a bit high if those are stock temps.

    You sure you did not use too much thermal paste? And you sure your cooler is fully and tightly connected?

    Is this Tuniq Tower 120 or another one?

    yep im using a tuniq 120 and artic silver 5 TC. i dont think i used too much compound and ive tightened it to the point where my fingertips have blisters.. i thought about remounting it but...

    Be careful of the dram voltage value on the p3 bios, there is a bug where the voltage basically lies to you. Also, the higher it gets the more incorrect it gets. Its much more noticeable at voltages past 1.7. It was the cause of many of my stability problems before I basically said f-that ran the memory at 1066 and overclocked my cpu. It ended up being faster and much more stable.

    Well if you remount, post us some pics of the CPU and bottom of the heatsink when you remove it. Then we can tell you if you used to much or not.

    I have not used a Tuniq, but read good things about it and planned to get one for a customer a while back before he decided to go water. I at least thought they were pretty good, but maybe not for quads so much?

    I raised and tested the Vcore up slowly from 1.225 to 1.28. I've been getting progress, rather than 2 cores fail instantly within minutes, 1 core failed after a couple of hours.. 3 while the rest kept at it for 6. but my temps ranged between 64-71. i tried increasing the CPU Term and MCH core to 1.26 to see if that helped but it still error'd a couple of hours into the test. Should i continue to raise my Vcore? i had the same results with CPU Term and MCH Core at 1.24v, should i just keep it at those levels?

    I probably wont remount until i get my system stable. but i will post pics once removing the headsink.

    I would leave MCH Core at once place during your testing, whatever you found to work best either 1.24-1.26 sounds good.

    Then raise Vcore until things do not fail. If you feel Vcore is getting to be a bit much then raise Vtt, but don't raise them all together or you will never find what works

    I'd say maybe set MCH to 1.24 or 1.26 then set Vcore to 1.32 for now and Vtt to 1.28 and see how that goes. If all is well then you can try one lower Vtt first, if no luck raise it back and then try less Vcore until you find the sweet spot

    Reporting back,

    im still testing for stability, primetests seem to run much longer between 6-10hrs before failing, so its some progress. my current voltage setting below: FSB: 450 - 3.37ghz, ram is 1500mhz @ 3.33D.

    Also i reseated my heatsink. below are the picture you requested.





    It doesnt seem like i applied too much AS5, however i did apply it incorrectly for a Quad core CPU so i followed AS5's instructions. Cleaned both CPU and heatsink thoroughly and reapplied ( 1 strip down the middle). seated it nicely. and the results?!...

    i still get the same average temp . Ah well at least i tried. i may look to lower Vcore and upping Vtt as my temps have hit 74 degrees!

    Ya, that does not look like too much Paste, I think you are fine there. Just must be that heatsink isn't as good as we all expected when you bought it :)

    I think the best method is a small amount in the center, the "Pea" or "Rice" method. I used to know where a great review on all the methods was posted with test results and images of how they look after being applied. And they concluded the same as well

    I think you may just need more Vcore, so your Vcore and Vtt are not so close together. That or you need less Vtt with more Vcore. Just something that could be the issue, often when they are close like you have it can cause issues, but not always.
