Having made a quick vmode on my 8800GTX, I wanted to share with you the steps to follow to help you and can motivate the uninitiated. The goal is not to present the vmode the 8800GTX, but rather to show the steps and procedures of this one.
WARNING: I am not responsible if you toast your graphics card. The experiment is hazardous, you do so knowingly.
1st Step: The hardware.
Indispensable to a vmode GPU:
- Potentiometers
- Soldering iron 15W or even less
- Son
- Screwdrivers
- Multimeters
- Pewter
Not mandatory but strongly recommended :
- What steps up (get on the old molex power for example or the recup like me)
- Scotch and / or glue gun
- Welding tongs
Here you need a pot of 20kohm for Ram and a 500Ohms of the Core.
2nd Step: Welds and installation of pot and molex.
Before addressing the welds on the pcb, you weld on the pot. It will in addition to workout.
You can use colors to differentiate.
So I would take for the Black Mass, Red for the Core and White for the Ram.
- Start by taking your meter and your screwdriver to put your pot to their respective values. Let 20kohm 500Ohms and in my case.
- Can your pot Core (500Ohms) solder black and red. (Mass and core)
- On your pot Ram (20kohm) solder black and white. (Mass and ram)
- And to finish on your molex, solder the black, red and white. (Mass, core and ram)
