I just HAVE to post this cos I receive a lot of PMs about the Vmem modd and I'll post here so as to be seen.........
The VTT is a bit dificult cos a trace HAS to be cut.....So we leave it........
The whole Vmem thread on IC7 Mobo is WRONG......It's based on trick the winbond chip to read less Vmem and on it's output give more........It wants some mamperes to work right......With ONLY one resistor and a BIG one(330 Ohms) you drop it's "reading" voltage BUT you DON'T feed it with the current it wants so as to work properly......The secret is : Unsolder the R50 resistor and on it's place solder a 10 Ohms(ten Ohms) resistor......Now on the left side of the resistor of the 10 Ohms,the side that is close to winbond chip,you SOLDER a trimmer of 220 or 200 or 330 Ohms to GROUND.........After soldering it you take a multimeter and you put it in Ohms reading.......You trim the trimmer so us to show you it's max resistence....You'll NOT see 330 Ohms(in case of a 330 trimmer....You'll see about 70 Ohms.......If I remember well.....Boot up and you'll mesure with a 200 Ohms trimmer about 2.73Vmem........You can now trim it slowly and you can get Vmem as much is your 3.3Volts line minus .12Volts......Example.....IF your 3.3Volts line is 3.4Volts , you'll get about 3.28Vmem.........and so on......If you modd your PSU at 3.6Volts , you can get as high as 3.48Vmem..........With this modd you do NOT have to worry IF your mobo is going to start or not cos with the way the Vmem modd is done(with the 330 Ohms resistor in R50's place) is wrong........With this Modd It'll start........Good luck.........
