8800GT VMods

[Mascaras]

This guide applies only to the G92 based nVIDIA 8800GT 512MB with the reference design circuit board.
If your card has different layout feel free to report here, and, if possible post clear pictures of the card.





Btw, here are some easily accessible vGPU measuring points:

Addendum:
- stock vGPU voltages for this card are 1.05v (2D idle) and 1.10v (3D load)
- stock vMEM voltage for Qimonda GDDR3 (HYB18H512321BF-10) is 1.80v ±5%
- 1kΩ (or higher) variable resistor can be used for the vGPU mod in order to maintain the minimum voltage close to stock. A 500Ω VR will force the vGPU slightly higher than stock vGPU even when the VR is tuned for the lowest vGPU = maximum resistance.
- vGPU pencil mod turned out to be virtually impossible
- usage of a multimeter is strongly recommended
- ENJOY! :up:

[EDIT:]
8800GT features the same vGPU (Primarion PX3544BDSG) and vMEM (Intersil ISL6549CBZ) controllers as 8800GTS and GTX, devising the mods shouldn't be much of a problem eventhough the PCB layouts aren't the same, the controllers' sense pins are...

Since I don't have a G92 based card I'm going to need some assistance from people who actually have the card for detailed pics of some areas of the card [done] and some resistance measurements [done].

A guide for performing the mod via variable resistors or pencil can be found in this thread/post once required data is available. Alternately, as it is likely people are already working on the mod it might happen that all will only find here is an external link to the mod instructions (if such a guide pops up before this thread delivers).

Discussion about the mod sparked in FUGGER's G92 thread here.







Oh, and here is the vMEM mod & vMEM measuring points (stock vMEM is 1.8v ±5%)

up to 1.2v >> safe
1.2-1.4v >> should be OK
+1.4v >> dangerous

alguem cunhece uma pessoa de confiança k faça os Mods a esta grafica?
