I still didn't try the mod on the booster, but I'm using separate mosfet's because I also need to regulate the vbt/vtt as my board's supllie is smoked.. Maybe we can make a 3rd version of the mod where u use the other half of the lm358n and a mosfet (irf640) to make a vbt/vtt supllie, because with only the booster, the vbt/vtt doesn't follow vdimm... I think the only extra components are a mosfet and 2 identical resistors and maybe a small cap..

When using a decent mosfet like a irf640 orso I don't think it's necessary to heatsink it as vbt/vtt doesn't draw big currents...

I'll say it again: Nice job persivore!!!

Thanks Rub
Vtt is specified to need a maximum of 3amps iirc, so almost any small power MOSFET should be ok for a Vtt regulator and it souldn't need a heatsink. I don't know if the motherboards Vtt supply will like having an extra voltage put across it, as with the Vdimm supply and the booster, but I don't see why it wouldn't work. Putting the Vtt supply on the booster would mean that you would have to mod your board tho, which people might not want to do. I'll look into that
I was thinking about using the unused 1/2 of the LM358 for OVP, but I didn't think that it would be necessary.

@ b|lly
Thats a good idea. Is there enough space around the Dimm slots for an active cooler?
