THIS IS NOT FOR NEWBIES!!
You should know how to solder very well, and have good soldering skills.
As usual, any damages you make to your motherboard is at YOUR OWN RISK and we (OCWORKBENCH
and Author) are not liable for any damages or whatsoever.
This is just universal vdimm mod wich works very well in this board. Both vtt
controllers output 1.65v which is half of vdimm.
Most, if not all,
dimms handle 3.3v, check datasheet of
dimm chips first to see if maximum absolute voltage is "-0.5v to 3.6v". Then
grab some ram
heatsinks and a fan, youīll need it.
Use a 47k pot between the 2 red points, and put it at half, reducing the
resistance to increase the voltage.
The board has a overvcore protection at 2.1v(if u put more your board wonīt
boot), wich may have a workaround by adding a pot to the vsense pin -> ground
and reduce the quantity of voltage the controller is thinking itīs receiving.
I havenīt any values tried for fixed resistors, but i think 1K ohm should yeld
As always go to www.ocinside.de
and do pinmods to 1.85v and then do the mod to push to <2.1v
My voltmod released, and iīm currently only running 1.82v, but i had it 2 months
My recomendations are: SINKS AND A FAN ON THOSE MOSFETS, they get very hot at
1.85v let alone >2v.
