no, in your mod V2 stands nothing about lifting pin4. As far as i understood is pin 4 the pin where the ATTP-1 gehts the anode-signal of the thermal diode ? When i lift this pin the ATTP gets no more signal from the diode or misunderstood i something ?
Ive build a 0815' SMBus extension with the MAX1668MEE first, tried to connect THDA and THDC on a sensor input of the 1668 (used cd-Audio-cable with huge groundwires connected to ground on the Vcc Socket and on my circuit). Got temps at 29 or 30°C, no fast reactions like all others told like the behavior of the int-diode should be. So i implemented a MAX6657 in the same circuit only for the cpu-diode, coz it seems that the whole world uses 6657 for the int-diode ;-).
Same problems as before, 29-30°C and no reactions under prime95 or idle.
In the meantime got some problems with the SMBus, posting at the MBM board, got some response from someone who done this mod while disconnecting the THDA and THDC pins from the Mobo for measuring, but i thinked that the thermal guard function of the abit makes this solution not so easy for me so he found your post here and told me about it.
As far as i know, (no learned electrician) is there not big difference between the winbond and the max6657 ic in the handling of the 'hardware-input' (both specified too for cpu-diode measuring) leaving offsets out.
So after my mail to you i connected the cd-rom audio cable (only one wire)
to the pin4 and to the DXP on the 6657. Same results, 29-30°C.
Checked my circuit again, tried different sensors , all worked perfect on the 6657.
changed the 6657 to another one .. same problems...
Cutted the cable (interferences?) as short as possible (shorter then the lenght you need to reach the winbind) same problem...29-30°C....
Today i got my new cpu, an 2600mobile IQYHA, had a rest of hope that maybe it was my old Thunderbird who made the problems, rechecked the soldering of circuit and of pin4 ... all ok, but ...
yes .. same problems .. 29-30°C .... no fast reactions .. nothing like it should behave ...
so im out of ideas what to check or try with the 6657 solution...
So a new roman, but thats my whole story about my journey exploring the SMbus and the nf7-s v2 ....;-)
