DFI LAN Party Model NFII Ultra B VDIMM mod

[Holst]

Following a request from Iolao I knocked this one up.

See the above lengthy thread for more info on the board.


The Vdimm is regulated by a simtech SC2616 the same as used on several other modern boards including the Epox 4PDA2+ rev2.

The successfull mod for 4PDA2+ is detailed here.

So the same pryncipals should apply.

The FB mod is pin1 to ground using 200k VR on 4PDA2+, resistance values may differ on this board so please take your time when turning the pot.

Question is where can you solder onto pin 1 (as this is an MLP package) This is pretty easy as with the excelent pics ive been sent we can easily follow the trace from pin1 to a SMT resistor on the board that we can easily solder onto.

The below mod is UNTESTED and should not be attempted unless you fully understand what you are doing.
I would appreciate if somebody could tripple check that I have got pin1 correct, and that my other logic is sound.
