Thread: Q9550 + EP45 UD3R ...too much voltage?

    Default Q9550 + EP45 UD3R ...too much voltage?

    Hi guys, I've been trying to figure out a stable setting for days now. And i just can't seem to get it right, If i get my memory right then something or the other is wrong. This is my first time OCing but so far im getting the hang of it and ive been OCing for five days straight now.

    Problem: is i finally found a stable speed but it seems that my voltage is too high, while i read other people setting and its around 1.2ish. Please help me. I just want to get 3.3 Ghz STABLE (i like odd numbers)

    system:

    Cpu: q9550 E0 stepping (heard this runs cooler and better)
    MB: GA-EP45-UD3R
    RAM: g skill pc2-8500 1066mhz 5-5-5-15 4GB(2x2) + 2gb(2x1) = 6gb total
    PSU: 600w FSP Epsilon

    here we go: (bold is my setting)

    If i set the Vcore to auto, then vdrop gets higher about .16 but vdroop is always good no matter what i put.

    The reason why i set it to 1.31875 because when its on auto, it will automatically set it to 1.312 or so.

    So far its stable (knock on wood) under prime95 for more than 10 hrs. and i checked single sticks of ram at 1066 at 5-5-5-15 for errors using memtest86+ and theyre all fine.

    Thanks a lot for helping me.

    UPDATE: Since i figured that the voltage is too high, I decided to change the voltage again manually.

    I reduced the voltage to 1.2675( or something like that), which is 1 notch higher than 1.25 (auto setting). I did this cause i read somewhere that the MB tends to overvolt when set to auto. I ran IBT and it passes and memtest86+ and it passes too.

    My vdrop and vdroop is much much better than before.

    Does this sound right to you guys? and do you guys think i should lower it to 1.2500v (vcore) or lower than that or do you think its fine now?

    thanks again for any help guys.

    My Q9550/UD3P/8GB DDR2 runs 3.5Ghz 412x8.5

    With BIOS CPU vcore set to 1.18125v Which reads 1.152v @ idle in CPU-Z.

    So, you might wanna try for a lower vcore.

    My Q9550 has a VID of 1.300V and it will run at 8.5 x 445MHz at stock voltages!!

    Every chip is different, but you shouldn't have to touch the stock (Normal) voltages to hit 400MHz FSB.

    I have been told many times to change all the voltages to "normal" instead of "auto" On "auto" the board will bump the voltages too high. It should be more stable with all (except the ones you change manually) to "normal". Hope this helps.

    Yeah, that was a typo...D'ho

    Meant 1.152v

    set pci e to 100mhz, as when raising fsb, you also raise the pci e mhz, which can cause corruption.
