Yeah, i'd like to at least go 1.35v for some 900mhz action on water.:up:Quote:

In addition to that, I almost burnt the card last night, straight after writing a drunken post on i4 i started playing with the volts, not realising my probe was in the vCore (CPU) read not vGPU. Kept turning and wondering why my volts werent budging.
Next thing i smelt an aweful burning smell and i pretty quickly realised what was happening. Dont know what i had turned teh volts up to, but the card seems to have survived. :clap:
that is amazingQuote:

lucky it wasn't air cooled
how the heck did it survive such a spike
WOW MAN
you just gave hipro ideas i think :D
watches him bench at 1.8V now :rofl:
Given the burning smell, i'd say at least something was damaged.
Maybe i burned a phase of the power supply circuit?
But teh card still runs, havent benched it though.
Bump for more details/confirmation/numbers on the GT OVP mod.

Anymore info from anyone, or has everyone just gone into the main thread?Quote:

Alex, does your resistance across the OVP resistor read constant value? Or always changing?
Ohhhh.......C'mon you guys.......!...... :D .....Who's gonna solder extra coils in parallel with the existing ones so to avoid the BIG Vdroop of it and then test it in real?.....
ONLY thing you need, is to unsolder some coils from an old motherboard and then solder them onto the VGA with a lot of heatage on the soldering iron..... ;)
hipro5 The purchase of the coil also I shall try to make this mod.
Get some .68uH at 25A+ each (at 25*C)..... This you can be put?
Yes.......ALSO if you don't mind, solder a couple of electolytic capacitors in parallel with the ceramic ones.....2200uF/6.3V whould be fine.... ;)Quote:

Can i use the caps and R47 coils from a P5B Deluxe?

For anyone interested in performing hipro's vGPU smoothing mods, here's a confirmed correct diagram of how to achieve it
http://img.photobucket.com/albums/v3...scan-front.jpg
The caps need to be electrolytic 1500, 2200 or 3300 uF with the '-' terminal on the ground side of the SMD cap, and the '+' terminal on the vGPU side.
The coils should be from an old mobo and just soldered across the existing ones.
Thanks T_M for the help...... :)
Tried the caps couple weeks ago, not of great use, no better overclock or higher benchable voltage. It's the coil that needs a mod. 'Any coil' will not help, you need right value's.
Darn, and i was about to do the mods with 'any values'.
So, what do i need?
'any values' from 0.47uH to 0.82uH...You can put even a 1uH.....:DQuote:

Is it the size that determines the value? If so from a photo could you say if OK or not?

going to do this now that there is a picture!!!
GREAT JOB GUYS!
T_M what will those mods achieve for you
Higher GPU clocks
