    Default extremely high vdrop/vdroop

    Set to 1.55v in the bios it is about 1.472 idle and 1.392 ~ 1.402 running prime95. I have this thing overclocked to 3.6, and I have no idea how it stable at those volts. Can you help me with a pencil mod? I dont want any of that stuff involving soldering because I will break it. Thanks

    board is a ep45-ds3r with f10 bios

    What motherboard do you have? Have you tried LLC? Can you be a little more specific and someone will help you I'm sure.

    Hey Guy(ComputerRuler) I have the GA-EP45-DS3R too. What is it you are trying to do and if I can help, I will. I have had a GAEP45-UD3LR up to some pretty high clocks but, I bailed at about the moderate OC range.
    What make and model RAM are you using? About the parts information you can use the information programs from the sticky at the beginning of this thread. Then simply copy and paste the information everst works n\best at this. I believe its everest Ultimate edition or Sisoftware SANDRA here is a link http://forums.tweaktown.com/f69/late...y-tools-30530/
    I also have a thread here somewhere ahh here is link - > http://forums.tweaktown.com/f69/ga-e...estions-29086/ enjoy!

    Normal vdroop with 100% loading is about 0.06 volts with ep45 mobos.
    This isn't an issue unless you're trying for an extreme overclock (above 3.90GHz and/or cpu host frequency above 500MHz).
    Using LLC (Load Line Calibration) enabled will lower vdroop, but might shorten the life of your cpu. There are many opinions (pro and con) regarding enabling LLC.

    Follow steps 1 - 4 in this post to provide full hardware info and to post your current bios settings.

    Did you load optimized bios settings before you made your bios changes?

    I have no LLC. I dont see what bios settings have to do with a pencil mod.

    I'm not aware of an EP45-xxxx pencil mod for reducing vdroop, but there might be one available somewhere.
    LLC is a bios feature to help reduce vdroop, often by up to about 50%.
    I am trying to get rid of my vdrop/vdroop.
    As stated earlier, this is sometimes needed with extreme overclocks, but vdroop is your "friend" at stock or moderate overclock levels.

    Motherboard Voltage Control
    CPU
    Voltage Types------------ Normal -------- Current -----
    Load-Line Calibration ----------------- : [Disabled] <--- this isn't in your bios?
    CPU Vcore --------------- ?.????? ---- : [Auto]

    CPU Termination --------- ?.???V* ----- : [Auto]
    CPU PLL ----------------- ?.???V* ----- : [Auto]

    You seem to be fixated on eliminating vdroop. So be it.
    I'm out of this thread.

    Noope, not there at all. Anyways, I found a guide on how to do it. It involves some soldering, but I think I can do it.
