My Russian is not so good, but from what I understand, RT8105 should be the same as APW7065. For a higher output voltage (vmem), we need to lower the resistance from pin 6 (FeedBack) to ground. (already 780Ohm on my card).
A VR with a value of 10k or 20k to ground should do the trick.
Modding, testing, pictures tomorrow...
