    Dfi infinity p965-s vdroop HELP!

    Hi!!In the pic below i draw the pwm layout of the dfi!!I need help from the experts here to find what i must do for the vdrop mod!!The px3539 is an 1 to 4 pwm controller connected with 4 px3511 mosfet drivers!!!The px3539 has two fault outputs so i think the mod can be applied there???Also the 8 solid capacitors around the socket are 560uf at 2.5v,i was reading the blitz mods from hipro and i was thinking if i can add in parrallel 8 tantalum capacitors around 100uf to reach 2000uf (standar capacitor size) on each capacitor!!!

    I'm also interested in voltage modifications with this board, I need vcore mod, I found 1.95V to small for some CPU's. Any help is appreciated.

    For the vmod i think that the pin you need is the vsence!!This is the feedback input so i guess this will do the job!!But i'm nto sure about this!!!!

    Ford took an NSX , cut it in the middle , examined it with a microscope , to admit that they can ' t built anything like that !

    I've already ask question about Vdrop mod on DFI P965-S.

    HERE

    But apparently it's not possible and not useful

    Good luck

    yeah i agree!!It's very difficult to find something for vdroop!!!But i searched a little and i found a datasheet from another company that makes a very similar chip!!It's 6-phase but all the cacteristics are the same!!!So here are two pins that they seem like they manage the vdroop!!But i can't really understand their funcionality so anybody how knows these can help???

    I am impatient to see what that will give…

    There is small a vdroop but which can be rather painful at the time of large OC.

    Moreover I have just installed a HR-05 on my DFI P965-S and it goes well

    -5°C in idle and not tested yet in full
