    ATI 5750/5770 voltmod thread

    Usual rules... got a card? Post up high-res pics and lets get hardmods sorted out

    The guy I work with just bought one so I *might* be able to get 5 minutes with it+ a camera or get him to do it

    The 5770 reference has no IC2 interface ? Aka soft vmod, if you flash it to the asus bios you'll can use the Asus software for change the vcore.

    Best regards

    5770 has Volterra VT243WF memory VRMs (those north of GPU VRMs), and those chips don't need any external controllers so no need to try to find one.
    Shamino posted a possible mod for VT242WF over here - and it should work on VT243WF too. If it works on VT242WF, that is.
    You were not supposed to see this.
