    Default Need help optimizing X3220 (Q6600) OC on GA-EP45-UD3L

    Hi all, I'm new to these forums. I recently began overclocking my X3220 on a GA-EP45-UD3L. Here are my specs:

    That isn't very long test at all? Why did you say you are stable, or am I misunderstanding you?

    You need to run Prime95 or Orthos, one at a time only, for 12-24 hours or so not a few minutes.

    Try these changes

    Ahhh I see...I was doing stability testing incorrectly this whole time. I thought having both Prime95 AND Orthos would accelerate the process but I was wrong.

    I will input your settings into bios and attempt stability testing the correct way and get back to you.

    Yes, you need to test for much longer for starters. 4-8 hours shows you are fairly stable, 10-16 shows you are very close, and 24-x shows you are for sure stable.

    Quicker is not going to tell you anything, and running two similar test like that at once is actually slowing things down and could cause errors in itself.

    If you want quick testing, and you have a good cooler, try LinX for 10-20 passes with All/Max memory chosen

    I managed to get Prime95 to run stable for 4 hours with the following settings. Load temperatures hover around the 65C mark for the hottest core in CoreTemp. I am looking to further optimize my system if possible.

    Nice, so it ran 4 hours then you stopped it right, it didn't crash out?

    As far as LLC is concerned, it appears the Q6600 series can handle it fine. However I am still a little paranoid about it shortening my CPU life. Do you think it would be better for me to turn LLC on and reduce voltage or keep it off and use an elevated voltage? BTW my processer is G0 stepping.

    Thanks again for your expertise.

    Great to hear man!!

    LLC is only scary because of a few reported CPU's dying a long time ago, which were never proven to be caused by LLC directly.

    I suggest using it, then you will be able to use less Vcore at Idle. See how you are stable now for 6 hours at 1.44 Vcore under load? All you need to do is enable LLC, then adjust your BIOS Vcore until again under load you get 1.44V, which will be much less at idle then you are using now.

    It is safe, I have always used it myself and never have any problems on any systems. It is up to you of course, but I'd use it so you can use less vcore overall

    Following your advice I made the following changes:
    Load line calibration......................[Enabled]
    CPU Vcore….……….........................1.48V

    Computer was again stable for 6 hours in Prime95 before I stopped it. I will continue trying to optimize the voltages as I go. One thing that bothered me is that under load the temperatures could approach 68-70C. Is that ok for my processor?

    Ya that is ok temps, and actually not that bad.

    Keep in mind you never will load your computer like Prime95 does, only when using prime95 :)

    Keep testing, you may be able to lower the Vcore more still, and maybe Vtt a little too
