    i didn't pay much attention to vcore but i'm guessing auto did something >.> and yeah it doesn't make sense that 5 mhz and pc won't boot, thats why i'm blaming auto volt lol

    why is you core voltage so high 1.44 is to high

    I had the same thought actually, though i took his word when he said he dropped them to stock.

    i guess 1.44 is stock because i loaded bios defaults.. Should i manually set it?

    Also, when i enabled linking it booted fine, but as soon as i put the ram ratio to 1:1, im getting the boot problem, i upgraded to 4GB ram recently if that makes a difference...

    if you didn't manually push it up then it should be stock voltages...

    I did some small research and i'm starting to think that its 1.44 by defaults... must've been the processors at the time.

    Don't touch the vcore, try just pushing the FSB up. Leave the Vcore to default or manually set it to default.

    I actually see some people with 1.41 vcores on their CPU-Z.

    hmmm what kind of rams are you using? are they of the same spec? i.e. if 4 dimms all 4 DDR2-800?

    I'm guessing your Rams don't like being overclocked much...

    Im using four of these:

    http://www.newegg.com/Product/Product.aspx?Item=N82E16820146599

    All running in dual channel.
    Also should i leave it at "linking"?


    I also set the overclocking option to manual. Is that right? I could also choose between "AI Overclocking" where i can increase overclocking by percentages.

    I'm not familiar with AI Overclocking since i use a Gigabyte board, but yes, use manual overclocking. It may be that the rams don't like having their bus speeds changed... you can leave them alone for now, focus on one bit at a time.

    With everything at defaults, pump up the fsb by increments of 0.1 ghz or so (usually i like to take big jumps for the first time, since i know its possible) though you shouldn't stretch it too far. You're not using any overclocking heatsinks so i'd suggest 3.3 Ghz safe for starters.

    Go into windows each time and check stability. If unstable, add a little or less vcore and see how it affects, if not turn down the fsb or sometimes even turn up.

    I've heard of strange occasions of cpus not liking certain speeds i.e. will boot at 3.2ghz, will not boot at 3.3. but will boot at 3.4ghz

    Play around but be gentle with your numbers. Once you find a good core speed and is stable, start tampering with the 1:1 ratio of your ram.

    My guess would be that 3.6ghz be your golden number. 400 FSB, 400 Mhz ram, so the full DDR2 800 at synchronous.

    Okay, thanks alot for the assistance. I will see what i can do

    Hmm.. As i increase my FSB my core voltage is increasing also... which is giving me some pretty high cpu temps. For example i only increase FSB 10 and it set it to 1.536.

    The E6850 has a VID of 1.35V most of the time. VID = default voltage for those people that didn't know that

    So dustin, are you suggesting mine is too high?

    sounds like you have yours set to auto voltage, yeah as dustin said throw your voltage back down to 1.35

    Yes thats too high, remember when I yelled at you about having 1.52v? You want to make sure your voltage is UNDER 1.4 with a stock cooler.
    Since you recently upgraded to 4 gigs, I don't know what that link is for, but that is low quality RAM, probably the same low quality you have right now, don't buy it.
