    is vPLL at 2v+ safe for these chips?

    Can you talk about how they scale with vPLL?

    Thanks

    nice clockage mate

    are you modding PLL to increase available voltage or some other reason?

    K404 ive tried up to 2.2vPLL i think as well as some ridiculous other volts, I'll say that these chips are looking mighty resilient from early testing, yet to kill one (hoping i dont jinx myself LOL)

    Awesome runs GT

    It seems a lot of E0 stepping 8 can go pass 6.5Ghz but with average imc.....The other way around for E1 stepping 9 with really good imc but can not go higher than 6.45Ghz.

    It will be interesting to see how retail will scaleup

    Ideal PLL varies from chip to chip and can move the CB around or remove it altogether.

    It s only 2 acess vPLL option. They put VCCIO & VCCSA on Same rail and vPLL in different one with the mod. Next verison of the PCB will correct that. Access to vPLL is important to prevent CBB or CB and can be under or above stock (1,8V) ... depend of CPU itself.

    Since 327 but you need to mod the board.

    XE3 mod ... and also little mod to the background of the board + cut PCB
